INSTALLATION

1.Foundation:

In order to achieve the accuracy from the 1118H TOOLROOM LATHE, it is essential that the machine be installed on a solid concrete base to eliminate any possible vibration and be properly leveled. Should the machine be used free-standing it is important to check regularly to be sure the machine is level

2.Lifting the machine:

The gross weight of the lathe is approximately 830kgs. This should be taken into consideration when choosing the equipment for lifting the lathe.

It is recommended that the machine be lifted using a rope or cable placed around the bedpan as shown in Fig. A. The carriage should be moved towards the tailstock for balance and padding put between the edges of the machine and the rope or cable.

2

3.Cleaning:

Each lathe is coated with a rust proofing grease prior to shipping. This grease should be removed with white spirit or kerosene before moving the cross slide, carriage or tailstock. DO NOT USE CELLULOSE SOLVENTS FOR CLEANING AS IT WILL DAMAGE THE PAINT.

When cleaning, pay particular attention to the slides and spindle nose. It is important that the end guard is removed. After cleaning, all parts should be dried with a soft cloth and coated with a thin film of oil.

4.Leveling: Fig. 2

After the lathe is placed on its foundation it must be properly leveled. There are six adjustable feet located under the corners of the pedestal base.

a.Place one pad under each of the feet

b.Loosen the setscrew “A” and use a pinwrench to raise or lower each foot as appropriate for leveling.

c.Be sure all feet resting firmly on the pads.

d.When leveling is completed, tighten setscrews “A” and recheck the lathe to be sure it is still level.

5.INSPECTION:

When you take delivery of the lathe, be sure to check for any possible damage caused by shock or vibration during transportation. Also check to be sure that all parts, tools and accessories are with the lathe.

6.LUBRICATION:

Once the lathe is in place, leveled and ready for use, proper lubrication is critical. Please follow the recommended daily, weekly and monthly lubrication instructions.

a.Vertical Screw:

Lubricate the vertical screw “C” via grease fitting “A” (Fig. 4) monthly or as needed. Add a few drops of light oil in the vertical screw “C” (Fig.4) and the brake cork “B” (Fig. 5).

b.Carriage Lubrication:

Fill the reservoir with Mobil Vactra Oil No. 2 or its equivalent. Maintain oil level in sight window “P” (Fig) 6.

c.Gear Box and Clutch Lubrication:

Maintain oil level in sight window “S” (Fig. 7). Carriage gearbox can be filled by removing plug “R” (Fig. 7). Use automatic transmission fluid Mobil 200 (Esso ATF or its equivalent). Oil should be changed every 400 hrs. The oil drain Plug “T” is located under the carriage gearbox (Fig. 7).

CAUTION: Use of any other type of oil in the gear box may result in damage to the Clutch surfaces.

d.Headstock Lubrication:

To absorb the radial and axial forces, the headstock spindle has precision

Preloaded angular contact ball bearings. These bearings are packed with grease for the life of the bearing and require no further lubrication.

7.ELECTRICAL CONNECTIONS;

The 1118H is shipped completely wired. To connect the power, do the following:

a.Turn the main switch “A” (Fig. 8) to “off” or “O”.

b.Check the voltage required which is indicated on the label at the rear of the electrical panel.

c.Loosen screws “B” (Fig.8) to gain access to the electrical connections.

d.Connect the power source to the terminals identified as, R.S.T. and the ground “G” in the electrical panel (Fig. 9).

e.To check for proper rotation, place control lever “H” (Fig. 11) to the “LOW” position, pull out spindle locking pin “E” (Fig. 11) and turn “C” (Fig.10) to the forward position. The spindle rotation is counter clockwise when viewed from the supply and interchange any two leads of the R.S.T. connections and re-connect the power. The rotation should now be correct.

Q P CAUTION: Running the lathe in the wrong direction will result in damage to the spindle speed change unit.

22.CROSS SLIDE INDICATING RING:

For convenience the indicating ring “B” (Fig. 20) on the cross slide is graduated in both inch and metric increments. (Increments are .001” and 0.02mm). The dial is spring loaded to simplify moving to a desired location. Type ad operation of the clutches are the same as the carriage. To use the taper attachment (if installed) nut “N” (Fig. 22) must be loosened.

23 QUICK ACTION TOOL POST COMPOUND SLIDE ASSEMBLY:

The compound is equipped with a quick action slide assembly, when used in conjunction with the auto thread length control described on page 7 will allow cutting threads into a blind hole or against a shoulder. Handle “K” (Fig. 23) is used to operate the quick action slide assembly. When making a cut for threads the handle is in the forward position and moved back toward the operator at the end of the thread. Feed for the thread depth is similar to a conventional lathe. The compound dial “J” (Fig 23) Is graduated in .001” and 0.02mm increments and is spring loaded to simplify moving to desired location.

23. POWER FEED UNIT:

The carriage power feed unit is mounted on the carriage and is powered by a direct current motor. (See Fig. 23).

The power feed can only be operated when the machine is running. To start the power feed turn cam switch “A” (Fig. 24) to the desired position. (This switch has three positions to control the direction of travel, “STOP” “LEFT” and “RIGHT”). The feed knob “B” (Fig. 24) controls the feed rate for both the carriage and the cross slide.

The feed rate should be pre-selected to suit each particular job depending on the type of material being machined, diameter of material, type of cut and tooling being used. Note: The numbers on the feed control do not represent thousandths per revolution or inches per minute. It is recommended that test cuts be taken to determine the proper feed rate and RPM for a particular job and the results recorded for future reference.

25:COOLANT:

The coolant pump is controlled by Switch “C” (Fig. 25) and has three positions, “ON” “OFF” and “AUTO” When in the on position the coolant is constant and it the

“AUTO” position the coolant is only on when the machine is running. The sump should be cleaned on a regular basis.

26.TAILSTOCK ASSEMBLY:

Pre-loaded ball bearings have been installed to support the load between the tailstock and the spindle. The tailstock spindle is graduated in both inches and metric. (1/8” and 1mm increments). The total travel is 3 ¾” or 92.25mm. The dial ring “D” (Fig.27) is spring loaded and graduated in both inch and metric. (0.001” and 0.02mm increments).

27.TAILSTOCK SPINDLE LOCK:

To lock the tailstock spindle move lever “H” (Fig.28) toward the spindle and away from the spindle to unlock.

28.TAILSTOCK LOCK:

The tailstock can be locked in place using lever “E” (Fig. 28). Lever “E” should be adjusted between clamp stops “F” and “G” (Fig. 28) so that when fully clamped it

does not touch stop pin “F”.

THREADING

CAUTION: DO NOT RUN THE SPINDLE IN REVERSE WHEN THREADING. The Tool Room Lathe is designed to cut threads quickly and accurately. The quick-

change gearbox permits instant selection of up to 36 different English and Metric threads. Threads can be cut to a shoulder by setting the automatic stop to a predetermined point in either direction. Before cutting a thread, select the proper cutting speed for the size of the thread and material to obtain the desired finish. MAXIMUM RECOOMMENDED THREADING SPEED IS 1000 RPM.

To set the quick-change gearbox for a desired pitch, pull the spring loaded knob “A” (Fig. 29) out as far ass it will go and lower it until can be moved sideways to the desired notch directly under the thread required. Raise the handle so the plunger can drop into the hole. If the handle cannot be raised far enough for the plunger to drop into the hole, loosen knob “F” (Fig.29), open the gearbox door and rotate gear “B” (Fig. 34) until the gears mesh allowing the handle to be raised.

Set ENGLISH / METRIC knob “B” (Fig. 29) so thread system to be cut is at the top, if it does no engage loosen knob “F” (Fig. 29) open gearbox door and rotate gear “B” (Fig.34) until it engages. To engage gearbox turn knob “D” (Fig. 29) to the treading position. If the sliding gear in the gearbox does not mesh with the headstock spindle gear it may be necessary to turn the headstock spindle by hand using the handwheel “P” (Fig. 31) until a definite click is heard.

Set compound at 61º and position cutting tool in compound slide tool post. Position the carriage so the tool is in the center of the part to be threaded.

Lever “F” (Fig. 11) is used to control direction of feed. When moved to the left carriage travel is to the left, when moved to the right travel is to the right and when in the center position the carriage is stoped.

NOTE: CARRIAGE POWER FEED UNIT IS NO USED FOR THE THREADING OPERATION.

Place lever “F” (Fig.11) in the center position and engage lead screw nut “Q” (Fig.32) by moving lever “R” (Fig. 32) clockwise. Set the two carriage stops “I” (Fig. 30) by loosening set screw “H” (Fig.30) to approximate thread length and re-tighten set screw “H”. Final adjustment of the stops can be made with adjusting screw “G” (Fig. 30). Make a trial run with the tool away from the work to pick up the shoulder or end of the triad by using the tool post slide. The tool should clear the right side of the thread by approximately 6.5nn.

NOTE: LOCK CARRIAGE STOPS SECURELY BEFORE STARTING THE THREADING OPERATION. DO NOT RELEASE CARRIAGE NUT “Q” (Fig.32) UNTIL THE THREADING OPERATION IS COMPLETED.

Once the stops are set, move the carriage to the right using lever “F” (Fig.11) and adjust the tool by use of the cross-feed.

Left hand threading can be done with the spindle running in the “FORWARD” direction, except the threading will be done from left to right.

OUTSIDE CHANGE GEARS

A set of five gears and bracket are provided as standard equipment for cutting threads not available in the quick-change gearbox. When set up per the chart on page 18, 10 threads per inch or 0.25mm pitch can be cut. Three gears are shipped on the bracket and the other two are in place of the shafts as shown at positions “O” and “F” (Fig.35).
