3.0 Safety warnings

1. Read and understand the entire owner’s manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This lathe is designed and intended for use b y properly tr ained and experie nced personnel o nly. If you are not familiar with the proper and safe operation of a lat he, do not use until proper t raining and knowledge have been obtained.

5. Do not use this lathe for other than its intended use. If used f or other purposes, JET disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always wear approved safety glasses/face shields w hile using this lathe. Everyday eyeglasses onl y have impact resistant lenses; they are not safety glasses .

7. Before operating this lathe, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended. Do not wear gloves.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adj usting wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes, use extreme caution and replace the guards immediately.

16. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of m oving parts, breakage of parts, mounting a nd any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

17. Provide for adequate space surrounding work area and non-glare, overhead lighting.

18. Keep the floor around the machine clean and free of scrap material, oil and grease.

19. Keep visitors a safe distance from the work area. Keep children away.

20. Make your workshop child proof with padlocks, master switches or by removing starter keys.

21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury.

22. Maintain a balanced stance at all times so that you do not fall or lean against moving parts. Do not overreach or use excessive force to perform any machine operation. Never force the cutting action.

23. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and safer.

24. Use recommended accessories; improper accessories may be hazardous.

25. Maintain tools with care. Keep cutting tools sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories.

26. Do not attempt to adjust or remove tools during operation.

27. Turn off the machine and disconnect from power before cleaning. Use a brush to remove shavings or debris — do not use your hands.

28. Do not stand on the machine. Serious injury could occur if the machine tips over.

29. Never leave the machine running unattended. Turn the power off and do not leave the machine until it comes to a complete stop.

30. Remove loose items and unnecessary work pieces from the area before starting the machine.

Familiarize yourself with the following safety notices used in this manual:

This means that if precautions are not heeded, it may result in minor injury and/or possible

machine damage.

This means that if precautions are not heeded, it may result in serious injury or possibly even

6.0 General Description and Nomenclature

Figure 2 – General Description of ZX Lathes

Bed and stand

The lathe bed (A) is made of cast iron with low vibration and high rigidity. Two precision-ground vslideways (B), reinforced by s upersonic frequency hardening, offer precision guidance for the carriage. The main drive motor is mounted in the stand (C) below the gearbox.

Headstock

The headstock (D) is cast from high grade, low vibration cast iron. In the head, the spindle is mounted in precision taper roller bearings. See section 12.0 for detailed explanation of controls. The electrical box is mounted to the rear of the headstock.

A 3-Jaw scroll chuck (E) and a 4-jaw independent chuck are included.

Feed gearbox

The gearbox (F) is made from high quality cast iron and is mounted to the left side of the machine bed.

Carriage

The carriage assembly is composed of the Apron, the Saddle, the Cross Slide, the Compound Rest, and the four-way Tool Post.

Apron (G). Quick travel of the Apron for positioning is accomplished by means of a bedmounted rack and pinion, operated manually by the handwheel on the front of the apron, or automatically by the feed direction handle.

Saddle (H). The saddle is made from high quality cast iron and rid es along the v-ways.

Cross Slide ( the saddle and used for cross feed operations. It moves on a dovetailed slide which can be adjusted for play by means of the gibs.

Compound Rest (J). The com pound rest, which is T-slotted and mounted on the cross slide, can be rotated 360°, allowing tapers to be turned. The compound rest travels on dovetailed ways, with adjustable gibs.

I). The cross-slide is mounted on

Four-Way Tool Post (K). The tool post is a turret design, mounted to the compound rest. It holds up to four tools simultaneously, and includes an indexing function. (Always use a

minimum of two clamping screws when installing a cutting tool.)

Tailstock

The tailstock (L) slides on a v-way and can be locked at any location by a clamping lever. The tailstock has a heavy duty quill with a No. 4 Morse Taper or No. 5 Morse Taper (18 ” and 22” model s) and etched graduation scale. The tailstock can be offset for taper cutting.

Leadscrew and feed rod

The leadscrew (M) and feed rod (N) are m ounted on the front of the machine bed. They are connected to the gearbox at the left and are supported by bearings on both ends. Both are equipped with shear pins.

Spindle direction control axle (O)

Spindle rotation can be reversed by simply moving the control lever (P) mounted at the right of the carriage. (Allow spindle to come to a stop before reversing.)

Travel setting rod (Q)

The stops can be moved and tightened into position at any point along the rod, to limit travel of the carriage.

Thread ch aser (R)

Simplifies the process of setting leadscrew/carriage positions in relation to the workpiece, by indicating the point on the leadscrew where the half nut can be reengaged to continue threading.

Steady rest (S)

The steady rest serves as a support for shafts on the free tailstock end. The steady rest is mounted on the bedway and secured from below with a bolt, nut and locking plate.

Follo w rest (T)

The traveling follow rest is mounted to the saddle, and thus follows the movement of the t urning tool. Only two fingers are required as the place of the third is taken by the turning tool. The follow rest is used for turning operations on long, slender work pieces. It prevents the work piece from flexing under the pressure of the cutting tool.

Work lamp (U)

Adjustable halogen lamp with independent on/off switch.

Coolant nozzle (V)

Fully adjustable gooseneck; flow is regulated through a valve lever at its base.

Foot brake (W)

Activates a braking strap at the motor for emergency stopping of all lathe functions.

Chuck guard (X)

Hinged, with upper and front windows.

Micro stop (Y)

Used for manual carriage operation.

7.0 Unpacking

manual before attempting set- up or operatio n! Failure to comply may cause serious injury.

8.0 Installation

8.1 Leveling the lathe

It is imperative that the lathe be on a level plane; that is, where headstock and tailstock center points remain aligned throughout the tailstock travel, with the bed ways absent of twist and thus parallel to the operational center line.

1. Finish removing all crate materia l from around the lathe.

2. Unbolt lathe from shipping pallet.

3. Choose a location for the lathe that is dry and has sufficient illumination (consult OSHA or ANSI standards for recommended lighting levels in workshop environments).

4. Allow enough room to service the lathe on all four sides, and to load and off-load work pieces. In addition, if bar work is to be performed, allow enough space for stock to extend out the headstock end. If used in production operations, leave enough space for stacking unfinished and finished parts.

5. The foundation must be solid to support the weight of the machine and prevent vibration, preferably a solid concrete floor.

6. Sling the lathe as shown in Figure 4, using steel rods or pipes of sufficient strength inserted through the holes in the bed casting. Do not lift lathe by the spindle. With adequate lifting equipment, slowly raise the lathe off the shipping pallet. Make s ure lathe is balanced before moving.

A lathe which is not properly leveled will be inaccurate, producing tapered cuts. Also, the

center point of the tailstock will vary as it is positioned along the bed, thus requiring constant readjustment of the set of the tailstock.

8. Use a machinist’s precision level on the bed ways both front to back and side to side, as shown in Figure 5. Take the reading in one direction every ten inches. Make sure the ways are clean and free of any debris before placi ng a level upon them.

9. Deviation over bed length (see Figure 5): a) Maximum 0.02/1000mm b) Maximum 0.04/1000mm

Figure 5: Leveling

10. Tighten foot screw nuts evenly to avoid distortion.

11. Leveling should be inspected occasionally, and especially if the accuracy of the lathe begins to diminish.

Figure 4: Lifting the lathe

Confirm that all suspension

equipment is properly rated and in good condition for lifti ng lathe. Do not allow anyone beneath or near load while lifting.

7. The lathe can be placed upon the cast iron leveling pads under each foot hole, and adjusted using the adjusting bolts with hex nuts. Or, it may be secured to the floor using bolts placed head-down in the concrete, and using shims where needed to level the machine. Refer to Figure 1 for mounting hole dimensions.

8.2 Completing installation

12. Clean all rust protected surfaces using a mild commercial solvent, kerosene or diesel fuel. Do not use paint thinner, gasoline, or lacquer thinner. These will damage painted surfaces. Cover all cle aned s urfaces w ith a light f ilm of 20W machine oil.

13. Open the end gear cover. Clean all components of the end gear assembly and coat all gears with a heavy, non-slinging grease. Close the end gear cover.

8.3 Chuck preparation (three-jaw)

Read and understand all

directions for chuck preparation. Failure to comply may cause serious personal injury and/or damage to the lathe.

The three-jaw scroll chuck i s shipped pre-installed on the lathe. It can be used for clamping cylindrical, triangular and hexagonal stock, and has reversible jaws.

The four-jaw chuck has independently adjustable jaws, and permits the holding of square and asymmetrical pieces. It also enables accurate concentric set-up of cylindrical pieces.

Before removing a chuck, place a flat piece of thick plywood across the bedways under the chuck to prevent damage to the bedways should the chuck fall from your hands. Alternatively, many users make a wood chuck cradle that sits atop the ways and accepts the specific diameter of chuck, for easier installing and removal. Figure 6 shows an example.

• If the index mark (A) is not between the two

arrows, i.e. the cam turns beyond the indicator arrows, then remove the chuck and turn the camlock stud IN one full turn.

• If a camlock will not engage, remove the

chuck and turn the camlock stud OUT one full turn.

Figure 7: Camlock

6. Make sure chuck is secure on the spindle with the camlocks correctly engaged.

Figure 6: Chuck cradle

To remove the chuck:

1. Support the chuck while turning six camlocks 1/4 turn counterclockwise with the chuck wrench from the tool box.

2. Carefully remove the chuck from the spindle and place on an adequate work surface.

3. Inspect the camlock studs. Make sure they have not become cracked or broken during transit. Clean all parts thoroughly with solvent. Also clean the spindle and camlocks.

4. Cover all chuck jaws and scroll inside the chuck with #2 lithium tube grease. Cover the spindle, camlocks, and chuck body with a light film of 20W oil.

5. Lift the chuck up to the spindle nose and press onto the spindle. Tighten in place by turning the camlocks 1/4 turn clockwise. The index mark (A, Figure 7) on the camlock should be between the two indicator arrows (B) when tight, as shown in Figure 7.

8.4 Break-in period

Do not run the lathe above 560 RPM for the first six hours of operation, to allow gears and bearings to adapt and run smoothly.

9.0

Maintenance/Lubrication

Lathe must be serviced at all

lubrication points and all reservoirs filled to operating level before the lathe is put into service. Failure to comply may cause serious damage to the lathe.

The ZX series lathe is shipped with oil in the reservoirs. Coolant is not included.

Use clean lubricants and check levels often, including before each working shift. To ensure proper lubrication, oil levels should not be less than the center of the oil sight glass. Try not to overfill, as this may cause leakage.

A chart is supplied in section 15.0 for quick reference to all lubrication points.

Unless specified otherwise, the lubrication points require a non-detergent, ISO 68, SAE 20W oil. The recommended brand for this lathe is Mobil DTE® Oil Heavy Medium.

1. Chuck – In addition to the lubrication already described in section 8.3, daily lubricate the chuck with SAE 20W oil through the ball oiler, shown in Figure 8.

Figure 8

2. Headstock – Oil must be up to indicator mark in oil sight glass (A, Figure 9). Top off with SAE 20W. Fill by removing the plug o n top of the headstock. To drain, rem ove drain plug o n the left side of the headstock at the lower rear corner. Drain oil completely and clean out all metal shavings. Refill after the first month of operation. Then change the oil in the headstock every two months.

3. Gearbox – Oil must be up to indicator mark in oil sight glass (B, Figure 9). Top off with SAE 20W. To add oil to the gearbox, remove two screw s on t he t op co ve r a nd r e move c o ve r . To drain, remove drain plug (C , Figure 9) on the left side of the gearbox. Drain oil completely and refill after the first three months of operation. Then change oil in the gearbox ever y si x m o nths.

Figure 9

4. Apron – Oil must be betwee n indicator marks in the oil sight glass (A, Figure 10). Top off with SAE 20W. Remove oil plug (B, Figure 10) to f ill. T o d r ain, r e m o ve d ra i n plug o n bo t t o m o f apron.

Drain oil completely and refill after the first three months of operation. Then, change o il in the apron annually. Pull knob (C, Figure 10) on the one-shot lube system and hold f or several seconds to allow oil to fill the pump. When the knob is released, oil will flow through various oil lines to lubricate the ways and cross slide surface. Perform this twice daily or as needed. When t he oil leve l is be low t he ind icato r ma rk, oil must be added.

Figure 10

5. Leadscrew and Feed Rod – Daily lubricate two ball oilers on the right side bracket (A, Figure 11) with SAE 20W once or twice per shift.

Figure 13

Figure 11

Saddle – Daily lubricate ball oiler (A, Figure

12) on handwheel shaft with SAE 20W. The anti-dust felt on both ends of the saddle

where it contacts the ways should be cleaned weekly with kerosene. If the felt becomes damaged, replace it.

6. Compound Rest – Daily lubricate two ball oilers (B, Figure 12) on top of compound rest with SAE 20W.

7. Cross Slide – Daily lubricate one ball oiler (C, Figure 12 – opposite side) with SAE 20W.

8. Toolpost – Daily lubricate one ball oiler (D, Figure 12) with SAE 20W.

10. V-Belts – Regularly check and adjust the tightness of the v-belts to prolong their service life. See section 14.6, Belt replacement and adjustment.

10.0 Coolant preparation

Follow cool ant manufacturer’s

recommendations for use, care and disposal.

1. R emove ac cess cover o n tailstoc k end at t he rear base of the lathe. Make sure coolant pump has not shifted during transport.

2. Pour four gallons (approximate) of coolant mix into the chip pan.

3. After machine has been connected to power, turn on coolant pump and check to see that coolant is cycling properly.

4. Replace access cover.

11.0 Electrical connections

Electr ical connections must be

made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded while in use to help protect the operator from electrical shock and possible fatal injury.

Figure 12

9. Tailstock – Daily lubricate one ball oiler (A, Figure 13) on top of tailstock with SAE 20W.

The main motor is rated at 7-1/2 HP (or 10HP f or model 2280ZX), 230/460V and comes from the factory prewired at 230V. Confirm that power available at the lathe’s location is the same rating as the lathe.

Power is connected properly when rotation of the forward-reverse knob (see E, Figure 15) to t he left position causes the spindle to rotate counterclockwise as viewed from the tailstock. If the chuck rotates in the clockwise direction, disconnect the lathe from the power source, switch any two of the three power leads (not the green ground wire), and re-connect the lathe to the power source.

11.1

25. Bed Cover (C, Figure 18): can be easily removed to clean out the stand.

• Never exceed maximum speed limitation of the work holding device.

• Before starting spindle, check that each handle or lever is at correct position to ensure normal engagement of gears. The spindle direction control lever should be at neutral position.

• If the brake becomes ineffective, turn off machine and adjust brake immediately.

• W hen operating spindle direction contro l lever, always turn it to correct position; never use “pre-position” for cutting at a reduced speed.

• Jaw teeth and scroll must be fully engaged, to prevent the jaws from breaking and being thrown from chuck (see Figure 19).

Figure 19 – Insufficient jaw tooth engagement

• Avoid long workpiece extensions, as parts may bend or fly off (see figure 20). Use rests or the tailstock for support.

13.0 Operation

The operator should consult shop manuals such as “Machinery’s Handbook” for cutting speeds and feeds appropriate to specific workpieces. Correct feed depends upon material to be cut, cutting operation, tool type, chucking rigidity, depth of cut, and desired surface quality.

IMPORTANT: A llow a break-in period for t he new lathe so that gears and bearings can adapt; do not run the lathe above 560 RPM for the first six hours of operation.

The following points must be

observed when operating the lathe:

• Ne ver tur n an y ha ndle s o r le ver s w he n spi nd le is at high speed.

• Change spindle speed only after spindle stops.

• Change feed rate only when spindle is at low

speed or is stopped.

Figure 20 – Improper setups

• Avoid short clamping contact (Figure 21, A) or clamping on a minor part diameter (Figure 21, B). Face-locate the workpiece for added support.

Figure 21 – Improper setups

13.1 Tool setup

The cutting angle is correct when t he cutting edge is in line with the center axis of workpiece. Use the point of the tailstock center a s a gauge and shims under the tool to obtain correct center height.

Use a minimum of two clamping screws to secure each tool.

3. Select desired thread using levers (B/C/D/E, Figure 22).

4. Set selector lever (A, Figure 23) to correct posit ion (ne ut ral).

5. Engage the half nut lever (B, Figure 23).

6. Make a test cut with scrap material and check results before cutting regular material.

13.2 Feed and thread selection

1. Reference the feed and thread chart on the front of the headstock (A, Figure 22).

2. Move levers and knobs (B/C/D/E, Figure 22) to the appropriate position according to the feed and thread chart.

Figure 23

14.0 Adjustments

Adjustments to the lathe,

especially those involving alignments of bearings, spindle, leadscrew, clutch, etc., should only be performed by qualified personnel, as improper alignments can damage the machine and/or create a safety hazard.

Turn off main switch and press emergency stop button before making adjustments to lathe.

14.1 Chuck jaw reversal

The three jaws on the scroll chuck are reversible, to hold stock with larger diam eters. See Figure 24. Loosen two screws with the provided hex key, remove jaw, and rotate it 180-degrees. Re-install jaw, and tighten each screw in in crements until fully tightened.

Figure 22

13.3 Thread cutting

1. Set forward/reverse lever (F, Figure 22) to desired direction.

2. Set selector levers (G/H, Figure 22) to desired R.P.M.

Figure 24 – Chuck jaw reversal

14.2 Gib adjustments

After a period of time, some moving components may need adjustment for play (or “backla sh”) due to wear. Do not overtighten gib screws as this can hasten wear to components.

14.2.4 Half Nut

Gib screws are located on right side of apron (C, Figure 26). Loosen the jam nuts and rotate the screws clockwise until any backlash is corrected. Then re-tighten nuts.

Figure 26 – Half nut gib adjustment

14.2.1 Saddle

Turn gib screws on eit her side of the saddle at t he rear to adjust the drag on the saddle.

14.2.2 Cross slide

Gib screws are located at front and rear of slide opposite to one another (A, Figure 25). To adjust drag, loosen rear gib screw one turn, and tighten front gib screw a quarter turn. Rotate handwheel to check play. Repeat as needed until slide moves freely without play. Gently tighten rear gib screw.

14.2.3 Compound rest

Gib screws are located at front and rear of compound rest (B, Figure 25). To adjust, use same method as for Cross Slide.

14.3 Tailstock off-set

Follow the procedure below to of f-set the tailstock to cut shallow tapers:

1. Loosen tailstock i n position by lowering locking handle (B, Figure 27) a nd loosening hexagon head eccentric shaft at back of tails tock.

2. Alternately loosen and tighten front and rear screws (D, Figure 27). Note: Front screw is shown.

The scale on the end of the tailstoc k base indicates amount of offset, and helps when re-centering.

If clamping force needs to be adjusted, use the hex nut beneath the tailstock body.

Figure 25 – Gib adjustments, slide and rest

Figure 27 – Tailstock offset

14.4 Removing gap bridge

1. To remove the gap bridge, remove four hex socket cap screws, and two hex cap bolts.

2. Tighten the hex nut s on the tapered a lignment pins to loosen the pins. Once loosened, they can be removed.

3. Gap bridge can now be removed.

14.5 Installing gap bridge

1. Clean the bottom and the ends of the gap bridge thoroughly.

2. Set gap bridge in place and align the ends.

3. Loosen the nuts on the locati ng pins and push down through the gap into the lathe bed.

4. Replace four hex socket cap screws and tighten alternately until all are snug.

14.6 Belt replacement/adjustment

1. Disconnect machine from power source.

2. Open end gear cover, remove lower rear cover and lower side cover. This will expose the motor and v-belts.

3. Loosen upper hex nut (A, Figure 28). Place scrap piece of wood under motor to act as lever. Lift motor up and block temporarily.

4. Remove belts. Install new belts onto pulleys.

5. Lift up on motor and remove temporary blocking.

6. Tension belts by loosening lower nut (B, Figure 28) and tightening upper nut (A, Fig ure

28) until light finger pressure causes approximately 3/4” deflection on each belt.

7. Install covers and connect lathe to the power source.

Figure 29 – Tailstock/Headstock alignment

14.8 Cross slide nut adjustment

The cross slide moves via a lead screw which drives a nut. This can be adjusted if backlash develops. Backlash is identified by turning the cros s slide handw heel le ft a nd rig ht – if there is a delay before any cross slide movement, the nut needs adjusting.

Tighten or loosen the two screws shown in Figure 30 until backlash is adjusted out.

Figure 30 – Cross slide nut adjustment

Figure 28 – Belt adjustment

14.7 Aligning tailstock to headstock

1. Fit a 12” ground steel bar between centers of the headstock and tailstock (Figure 29).

2. Fit a dial indicator to the top slide and traverse the center line of the bar.

If adjustment is needed, align the tailstock using the off-set screws (D, Figure 27) until the tailstock is aligned.

14.9 Shear pin replacement

The lead screw and feed shaft are equipped with shear pins, which are designed to break in order to protect the drive system against overload. A broken shear pin must be replaced.

Knock out the broken pin; line up the holes and insert new pin.

14.10 Steady rest adjustment

Always lubricate the fingers with grease before using the steady rest. The point at which the fingers contact the workpiece require continuous lubrication to prevent premature wear.

To set the steady rest (see Figure 31):

1. Loosen hex nut (A) to slide steady rest along the ways.

2. Loosen knurled handle (B) until it can be pivoted out of the slot.

3. Loosen three lock knobs (C), and back of f the fingers (D) using knurled handles (E).

4. Pivot the collar on its hinge and position steady rest around workpiece.

5. Firml y tighten hex nut (A).

6. Set the fingers snugly to work piece and secure by tightening locking knobs. Fingers should be snug but not overly tight.

Always lubricate the fingers suf f iciently with grea se before operating.

14.12 Carriage stops

Adjust each stop (Figure 32) by loosening two set screws, and sliding it along the rod. Rotate the stop so that the raised area is upward to contact the carriage. Tighten both set screws securely.

Position the raised area downward when the stop is not being used.

Figure 32

Figure 31 – Steady rest adjustment

14.11 Follow rest adjustment

The follow rest mounts to the saddle with two socket head cap bolts. The follow rest should be mounted so that locking knobs point away from chuck.

The sliding fingers are set similar to those on t he steady rest – free of play, but not binding.

15.0 Lubrication schedule and general maintenance

Regularly scheduled maintenance is crucial to ensure a long service life for your machine. The schedule below shows general cleaning, lubrication points and coolant replacement information for the ZX Series Lathes. Push stop button and power off before lubricating.
