6.0 MACHINE FEATURES

Figures 1 and 2 depict the main features of the Model EHB­8 Horizontal Cut-Off Bandsaw. The machine consists of a machine base onto which is installed a saw head.

6.1 MACHINE BASE

The machine base consists of a coolant collection pan mounted on two panels that form the legs of the machine. A shelf is provided under the collection pan that supports a coolant tank.
The machine bed mounts on the top of the collection pan. The bed supports the vise and the vise-tightening lead screw.
The coolant tank is equipped with a pump/motor assembly. The pump/motor circulates coolant through tubing to cool and lubricate the saw blade, the blade guides, and the workpiece.
A drainpipe is provided to connect the collection pan to the coolant tank. A screen is provided in the collection pan to screen-out cutting debris as the coolant drains into the coolant tank. Coolant is added to the tank by pouring coolant into the collection pan. The tank is easily removed from its shelf for cleaning and maintenance.

6.2 SAW HEAD

The saw head (Figure 2) consists of a drive motor, drive pulleys, gearbox, blade wheels, blade guides and supports, control panel, blade tension/blade tracking mechanism, wire brush, and the saw blade.
The drive motor is mounted on a pivoting plate that swings outward to provide drive belt tension. The motor is fitted with a step pulley; the drive belt connects to a second step pulley that is mounted on the input shaft of the gearbox.
A speed-reducing gearbox is mounted on the back side of the blade wheel box on the right side of the machine. The blade wheel (drive wheel) is installed on the output shaft of the gearbox.
A second blade wheel is located in a blade wheel box on the left of the machine. The blade wheel (driven wheel) is mounted on a shaft that is part of the blade tension/tracking mechanism. The blade tension mechanism is used to tighten the saw blade on the blade wheels.
The mechanism also has adjustment screws that enable the saw blade to “track” evenly on the blade wheels. The adjustment screws change the angle of the driven blade wheel shaft so the wheels are aligned. Tracking adjustments are generally made after the saw blade is changed but may be required periodically due to wear over time.

6.3 WORK STOP

A work stop (refer to Figure 3) is provided with the machine to allow cutting multiple pieces of identical length (refer to Figure 12). The stop consists of a rod onto which is installed a stop bracket, a tapered stop, a clamping knob and a locking handle. The rod is installed in a bore in the front of the saw bed. The stop bracket is positioned on the rod with the tapered stop toward the end of the workpiece. The bracket is moved in or out on the rod to establish the length of the workpiece.

7.0 UNPACKING AND ASSEMBLY

7.1 MACHINE SETUP

The cut-off saw has been pre-adjusted at the factory and several test pieces have been cut to verify cutting accuracy .
Remove the saw from the shipping skid; discard any hold­down devices. Place the saw on the shop floor; secure the saw to the floor using mounting anchors secured through four holes in the machine base. (Refer to Figure 1 for floor anchor bracket location). If the saw will be used to cut long pieces of stock, allow plenty of room for the length of the stock.

8.0 ELECTRICAL CONNECTION

The operating controls for the cut-off saw are located on the control panel (Figure 4) and consist of the following controls and indicators:
Coolant Pump Switch (A) – turns coolant pump on and off. Emergency Stop Switch (B) – press to stop the drive
motor.
Note: A micro switch also stops the motor when the workpiece is cut and the saw head is completely down.
Start Switch (C) – press to start the drive motor. The saw
head must be in the raised position. Power Light (D) – indicates that machine is plugged in and
the outlet circuit breaker is turned on. The machine does not need to be running for the power light to be on.
!
If the bulb is out, lamp will not light, but machine may still have power.

9.2 BLADE SPEEDS

The Model EHB-8 horizontal cut-off bandsaw is equipped with electronic variable speed raging from 80-310 FPM. The speed change is completed by turning the speed control knob (Figure 5) located to the right of the machine on the main motor. Change blade speeds as follows:
1. Raise the saw head so that it is not in contact with a work piece.
2. Press the motor start button on the main control panel.
3. Adjust the speed to correspond with the material that you are cutting (Figure 6 on page 9) Note: speeds are approximate.
!
Adjust speed dial only when machine is running.
Feed Rate Control (E) – this knob is used to set the amount of downward force that is applied to the saw blade. The feed rate is proportional to the opening of the valve. When set to zero, the saw head is locked in the raised position. Increasing the valve opening (counterclockwise adjustment) increases the feed rate; decreasing the valve opening (clockwise adjustment) reduces the feed rate.

10.0 BLADE SELECTION

The cut-off saw is delivered with a saw blade that is adequate for a variety of cut-off jobs on a variety of common materials.
Refer to Figure 6 for the speeds recommended for various materials. These speeds, while appropriate for many common shop cutting needs, do not encompass the wide variety of special blade configurations (tooth pitch and set) and special alloys for cutting unusual or exotic materials.
A coarse blade could be used for a solid steel bar, but a finer tooth blade would be used on a thin-wall steel tube. In general, the blade choice is determined by the thickness of the material; the thinner the materials; the finer the tooth pitch.
A minimum of three teeth should be on the workpiece at all times for proper cutting. The blade and workpiece can be damaged if the teeth are so far apart that they straddle the workpiece.
For very high production on cutting of special materials, or difficult to cut materials such as stainless steel, tool steel, or titanium, you can ask your industrial distributor for more specific blade recommendations. The supplier that provides the workpiece material should be able to provide you with very specific instructions regarding the best blade (and coolant or cutting fluid, if needed) for the material or shape supplied.

10.1 BLADE BREAK-IN PROCEDURES

New blades are very sharp and, therefore, have a tooth geometry that is easily damaged if a careful break-in procedure is not followed. Consult the blade manufacturer’s literature for break-in of specific blades on specific materials. However, the following procedure will be adequate for break­in of Jet-supplied blades on lower alloy ferrous materials:
1. Clamp a section of round stock in the vise. The stock should be 2 inches or larger in diameter.
2. Operate the saw at low speed. Start the cut with a very light feed rate.
3. When the saw has completed 1/3 of the cut, increase the feed rate slightly and allow the saw to complete the cut.
4. Keep the hydraulic cylinder needle valve in the same position and begin a second cut on the same or similar workpiece.
5. When the blade has completed about 1/3 of the cut, increase the feed rate.
Watch the chip formation until cutting is at its most efficient rate and allow the saw to complete the cut
(refer to Evaluating Cutting Efficiency section 11.2). The blade is now considered ready for use.

11.0 OPERATIONS

11.1 HYDRAULIC FEED CONTROL

The weight of the saw head provides the force needed to cut through the workpiece. The cut-off saw has a hydraulic cylinder that controls the feed rate of the saw.
The hydraulic feed control circuit consists of a single acting hydraulic cylinder (Figure 7) and a feed rate control (Figure
4). The feed control cylinder resists motion in the downward direction to control the feed rate. The control cylinder offers no resistance when raised upward.
The feed rate control knob (Figure 4) controls the rate at which the saw head is lowered. The control knob (needle valve) controls the rate at which the hydraulic fluid is released from the hydraulic cylinder. When the needle valve is closed, the cylinder is locked. With the needle valve slightly open, the cylinder permits slow, or light, downward force. Opening the needle valve further increases the feed rate and applies more force to the saw blade and workpiece.
The needle valve is adjusted until the saw is operating ef­ficiently. The efficiency of operation is usually evaluated by observing chip formation. Blade efficiency is further de­scribed on the following page.

8-in x 13-in Horizontal Cut-Off Bandsaw

11.2 EVALUATING CUTTING EFFICIENCY

Is the blade cutting efficiently? The best way to determine this is to observe the chips formed by the cutting blade.
If the chip formation is powdery, then the feed is much too light, or the blade is dull.
If the chips formed are curled, but colored – blue or straw colored from heat generated during the cut – then the feed rate is too high.
If the chips are slightly curled and are not colored by heat – the blade is sufficiently sharp and is cutting at its most efficient rate.

11.3 WORK SETUP

Referring to Figure 8:
1. Set the feed rate control knob (C) to zero.
2. With the lifting handle (A) raise the saw head (B).
3. Turn the vise handwheel (D) counter clock-wise enough to free the moveable vise jaw (E). Then pull the moveable vise jaw away from the fixed vise jaw(H).
4. Place the workpiece (F) on the work table (G). For long workpieces, provide support at the other end. If necessary, provide additional downward clamping to hold the workpiece securely on the worktable.
5. Clamp the workpiece (F) in the vise by first pushing the moveable vise jaw (E) against the workpiece. Then rotate the vise handwheel (D) clockwise to secure the workpiece.

11.4 SETTING THE VISE FOR ANGLE CUTS (NON-MITERING VERSION ONLY)

Referring to Figure 9, the vise can be adjusted through a 45-degree arc as follows:
1. Loosen the lock handle (E) that secures the fixed vise
jaw (D).
2. Rotate the fixed vise jaw (D) to the desired angle,
setting it to the scale on the back edge of the table. For accurate cuts, use a variable protractor to set the
position of the jaw, aligning one side of the protractor with the blade.
3. Tighten the lock handle (E).
4. Loosen the hex head bolt (A) on the moveable vise
jaw (C).
5. Place the workpiece (B) between the vise jaws (C, D).
6. Set the moveable vise jaw (C), pressing it against the
side of the workpiece (B) and fixed vise jaw (D).
7. Tighten the hex head bolt (A) on the moveable vise
jaw to secure the jaw.

11.5 SETTING THE VISE FOR SQUARE CUTS

The procedure for setting the vise for square cuts is identical to setting for angle cuts (above) except that a machinist’s square is used to set the angle of the fixed vise jaw (A, Fig.
10). Align one side of the square with the side of the slot (B, Fig. 10) in the table.
!
Never operate the saw without blade covers in place.

11.6 SETTING BED FOR MITERING CUTS (MITERING VERSION ONLY)

The saw head can be adjusted through a 45-degree arc as follows:
1. Ensure that power is turned off and then loosen saw
head miter lock.
2. Rotate the saw head to the approximate desired angle
as specified on the miter angle gauge. Then verify the exact angle with Engineers square.
3. Lock the saw head miter lock. The miter locking lever
extends through a slot in the front face of the saw bed. Rotate the lever to the right to tighten the lock and to the left to loosen.
4. Load the work piece and continue with steps below.
Make sure the blade is not in contact with the workpiece when the motor is started. Do not drop the saw head on the workpiece or force the saw through the workpiece.
To start the saw:
1. Clamp the workpiece in the vise. Refer to Figures 10 and 11 for examples of workpieces in the vise.
Be sure the blade is not in contact with the workpiece when the motor is started.
2. Start the motor and allow the saw to come up to speed.
3. Slowly set the saw down onto the workpiece and adjust cutting speed with the speed control knob (described on page 9).
4. Do not drop the saw head or force the cut. Let the weight of the saw head provide the cutting force.
5. The saw will automatically shut off at the end of the cut.

11.8 COOLANT FLOW AND NOZZLE POSITION

!
CAUTION
The coolant pump must be submerged before operating to prevent damage to the pump.

11.7 STARTING THE SAW

Important: The efficient operation of the cut-off saw is de­pendent upon the condition of the saw blade. If the perfor­mance of the saw begins to deteriorate, the first item that you should check is the blade.
If a new blade does not restore the machine’s cutting accuracy and quality , refer to the Troubleshooting section (or the blade manufacturer’s guide) for conditions to consider and adjustments that can be made to increase the life of the blade.
To change the blade, refer to the Changing Blades section on page 17.
12
Adjust the coolant flow shut-off valves at the top of the saw head weldment. The flow should be no more than the saw blade can draw into the workpiece by the movement of the blade.
The coolant flow can be stopped in two ways:
by the coolant selector switch (A, Fig. 4) on the control box (the preferred method)
by closing the shut-off valves
Note: The coolant pump is self-circulating when the shut-off valves are closed.

12.0 ADJUSTMENTS

12.1 BLADE TRACKING ADJUSTMENT

Refer to Figures 13 and 14. Blade tracking has been set and tested at the factory.
Adjustment is rarely required when the blade is used properly or if the blade is correctly welded.
If adjustment is needed:
1. Using the blade tension handwheel (D), make sure
the blade is properly tensioned. Keep proper tension at all times.
Note: Blade tensioning is described in the Changing Blades section on page 17.
EHB-8VS | EHB-8VSM
2. Raise the saw head (A) as shown.
3. Open the wheel guards (B).
4. Remove both of the blade-guide bearing
bracket assemblies (C).
5. Loosen three hex locking screws (E) in the
head weldment (G).

8. Turn the adjustment screws (F) to stop the motion of
the blade on the wheel as it gets closer to the wheel shoulder.
Put a 6-inch length of paper (J, Fig. 14) between the blade and the wheel as shown (the saw is still turned
C
on). The paper should not be cut as it passes between the wheel shoulder and the blade.
9. Turn the adjustment screws (F) slightly.
Repeat the insertion of the paper between the wheel shoulder and the blade until the paper is cut in two

CAUTION
While performing the following, keep the blade from rubbing excessively on the shoulder of the wheel. Excessive rubbing will damage the wheel and/or the blade.
6. Start the saw. Turn the adjustment screws (F) to tilt the idler wheel (Figure 14) until the blade is touching the shoulder of the idler wheel.
Note: As a general rule, make the same adjustment to the two adjustment screws on the right (F, Fig. 13). The single adjustment on the left is independent.
7. Next, turn the adjustment screws (F) so the blade starts to move away from the shoulder of the wheel then immediately turn the adjustment screws in the other direction so the blade stops – then moves slowly toward the shoulder.
!
Keep fingers clear of the blade and wheel to avoid injury.
J, Place paper here

Note: You may have to repeat the check with the paper several times before the blade and the shoulder cut the paper into two pieces. Do not hurry the adjustment. Patience and accuracy here will pay off with better, more accurate, quieter cutting and much longer machine and blade life.
When the paper is cut:
10. Turn the adjustment screws (F) slightly in the counter-
clockwise direction. This ensures that the blade is not touching the shoulder of the wheel.
11. Shut off the saw.
12. Tighten the hex locking screws (E).
13. Install the blade-guide bearing bracket assemblies
(C, Fig. 13).
14. Position the guides so the top bearing just touches
the blade (see Blade Guide Bearing Adjustment on page 16) .
15. Close the wheel covers (K, Fig. 15).

8-in x 13-in Horizontal Cut-Off Bandsaw

12.2 BLADE GUIDE ADJUSTMENT

Referring to Figure 15: The EHB-8 Bandsaw has two adjustable blade guide
assemblies, each consisting of the blade guide support or bracket (B, H) and blade guide (A).
The position of the blade guides is important in order to make accurate cuts and prolong blade life and is determined by the size of the workpiece. Adjustment is made as follows:
Left Blade Guide
1. Place the workpiece (G) in the vise (F) and clamp tightly (refer to Work Setup on page 8).
2. Loosen the left lock knob (C) only.
3. Slide the guide support (D) left or right so that it just clears the piece to be cut (G).
4. Tighten the lock knob (C).
Right Blade Guide
The right blade guide assembly is set at the factory and rests against the stop (E). It normally does not require adjustment, except to provide clearance for workpieces to be cut at a great angle. If adjustment is required, the procedure is the same as for the left blade guide adjustment.
It is always better to try a new blade when cutting performance is poor. If performance remains poor after changing the blade, check the blade guides for proper spacing. For most efficient operation and maximum accuracy, clearance between the blade and the guide bearings should be 0.001 inch. The bearings will still turn freely with this clearance. If the clearance is incorrect, the blade tracking may be affected.

12.3 BLADE GUIDE BEARING ADJUSTMENT

Referring to Figure 16: Guide bearings and guide inserts are located on either side
of the saw blade and provide stability for the blade when the saw is in operation. These bearings rotate on an eccentric shaft so the distance from the blade can be adjusted for optimal performance.
Blade guides provide blade support. Guide bearings and blade guides are initially adjusted at
the factory and should rarely require adjustment

Check the blade to make sure the welded section is the same thickness as the rest of the blade. If the blade is thicker at the weld, the guide bearings may be damaged.
EHB-8VS | EHB-8VSM
15
If required, adjust first one guide bearing and blade guide assembly then the other as follows:
1. Using a 3mm hex wrench, loosen two set screws (A) securing the eccentric bushings.
2. Using a 5mm hex wrench, loosen two socket head cap screws (D) securing the carbide blade guides
(E).
3. Position the bearings (B) by turning the bushings (C) with a flat-head screwdriver. Set the clearance between the bearings (B) and blade (F) at
approximately 0.001 inch. When properly adjusted, the blade should be in a
vertical position between the bearings as shown in Figure 17.
4. Tighten the set screws (A).
5. Adjust the blade guides (E) so they support the blade without pinching and tighten the socket head cap screws.
6. When the adjustment is correct, the guide bearings should rotate freely with slight pressure of the finger (blade stopped).

12.5 VERIFYING ADJUSTMENT ACCURACY

Refer also to Figure 18. T est cuts can be used to determine whether or not you have
adjusted the blade accurately . Use 2 inch round bar stock to perform these test cuts, as follows:
1. With the bar stock securely clamped in the vise,
make a cut through the bar stock.
2. Mark the top of the bar stock.
3. Move the bar stock about 1/4 inch past the blade so
you can begin a second cut.
4. Rotate the bar stock 180 degrees so the mark you
made is now at the bottom of the cut.
5. Make a cut through the bar stock.
6. Use a micrometer to measure the thickness variation
between the top and bottom of the disk you have cut from the bar stock.
The saw blade can be considered correctly adjusted when the variation measured is no more than 0.012 inch across the face of the disk. If you do not have a piece of 2-inch bar stock available for a test cut, use a larger diameter test workpiece rather than a smaller one. The maximum thickness variation on any test piece should be no more than 0.006 in. per inch of stock diameter.

12.7 COUNTERBALANCE SPRING TENSION

!
Disconnect the cut-off saw from its electrical power source.
The counterbalance spring is located on the rear of the saw table (refer to Figure 20). The counterbalance spring is used to adjust the amount of down force the saw arm puts on the workpiece when the hydraulic control cylinder is fully open.
If adjustment is needed:
1. Raise the saw arm to its full upright position and lock it in position.
2. Set the spring tension by adjusting the nut until 1-1/4

13.1 CHANGING BLADES

!
Use leather gloves when changing the saw blade to protect your hands from cuts and scratches. Use protective eye wear that meets ANSI Specification Z87.1
!
Disconnect the cut-off saw from its electrical power source.
Referring to Figure 21 (pg. 18):
1. Raise the saw head (A). Set the feed rate control knob to zero to lock the hydraulic cylinder, which will hold the saw head in place.
2. Open two hinged blade wheel covers (C).
3. Remove the blade guard (D) and column blade cover (E).
4. Turn the blade tension handle (F) counter-clockwise until the blade hangs loose.
EHB-8VS | EHB-8VSM
17
5. Using leather gloves to prevent cuts and scratches, pull the blade off the drive wheels (H) and out of the blade guides (J). Store the removed blade carefully before proceeding.
6. Slide the new blade into the blade guides (J), then loop the blade around the drive wheels (H) such that the teeth face towards the back and the smooth side faces towards the front.
This will permit the vertical side of the teeth to contact the workpiece first.
7. Push the blade so it is seated against the shoulders of the wheels (H).
When it is seated against the shoulder, turn the blade tension handle (F) clockwise to increase the tension. Do not over-tension the blade; tighten it just enough so it does not slip while cutting.
8. When the blade is properly tensioned, reconnect the saw to the electrical power source.
9. Check and adjust the tracking of the blade. Refer to Blade Tracking Adjustment (on page 14) if necessary.
10. Close the wheel covers (C).
11. Put 2 to 3 drops of oil on the blade.
1. Set the arm at the full horizontal position.
2. Open the drive belt cover to expose the drive belt and pulleys.
3. Loosen the belt tension adjust knob located in the rear under the motor (see Figure 23 for knob direction). Lift the motor upward to loosen the belt.
4. Remove the worn drive belt.
5. Put the replacement drive belt in the pulley position for the speed you require (refer to the Blade Speeds section on page 9).
6. Tighten the drive belt by turning the belt tension adjustment knob (see Figure 23). The belt must be secure enough it does not slip when the machine is running. Do not over tighten. This will cause prema- ture wear on belt and pulley bearings.
7. Reinstall drive belt cover and install knob.

4. Clean the chip sludge from the coolant tank. The frequency should be determined by how often the
saw is used.

15.0 LUBRICATION

Lubricate the following components at the specified frequencies and using the lubricants defined as follows:
Ball Bearings – the bearings are lubricated and sealed – periodic lubrication is not required.
Blade Guide Bearing – the bearings are lubricated and sealed – periodic lubrication is not required.
Upper Wheel Bushing – six to eight drops of oil each week. Pivot Points, Shafts, and Bearing areas – six to eight drops
of oil each week.

16.0 COOLANT

Change coolant on a frequency appropriate to the type of coolant being used. Oil based coolants can sour. Refer to the coolant supplier’s instructions for change frequency.
The general-purpose coolant is a mixture of water-soluble oil and water. Mix one part of soluble oil to ten parts of water (one quart of oil to ten quarts water). Eleven quarts of coolant is the amount required for the coolant pump to operate properly.
There are numerous coolants on the market that are formulated for special applications. Consult your local distributor for details in the event you have a long range production task, or are required to cut some of the more exotic materials.

14.0 CLEANING

1. Clean off any preservative on machine surfaces. After cleaning:
2. Coat machined surfaces of the cutoff saw with a medium consistency machine oil. Reapply the oil
coating at least every six months.
3. Clean up accumulated saw cuttings after use. Make sure the lead screw and rapid nut are kept free from saw cuttings and other material that would cause damage.
