Machine Features

Saw Head
Figures 1 and 2 depic t the main features of the Model J-7015 Horiz ontal Cut-Off Bandsaw. T he machine consists of a machine base onto which is installed a saw head.
Figure 1
The saw head (Figure 2) consists of a drive motor, drive pulleys, gearbox, blade wheels, blade guides and support s, control panel, blade tension/blade tracking mechanism, wire brush, and the saw blade.
The drive m otor is mounted on a piv oting plate that swings outward to provide V-belt tension. The motor is fitted with a step pulley; the V- 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 (driv en wheel) is mounted on a shaft that is part of the blade tensi on/tracking mechani sm. The blade tension mechanism is used to tighten the saw blade on the blade wheels.
Machine Base
The machine base consists of a coolant collection pan m ounted on two panels that form the legs of the machine. A shelf is provided under the coll ection pan that support s 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 wit h 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 collecti on pan to the coolant tank. A screen is provided in the collecti on pan to screen-out c utting debri s as the coolant drai ns into the coolant tank. Coolant is added to the tank by pouring c oolant into the collection pan. The tank is easily r emoved from its shelf f or cleaning and maintenance.
Figure 2
7
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 driv en bl ade wheel s haft so the wheels are al igned. Tr acking adj ustment s are generally made after the saw blade is changed but may be required periodically due to wear over time.
An electrical enclosure is attached to the leg panel on the right side of the machine. The enclosure contains the switches and fuses required for operation and pr otecti on of the dr iv e motor (Figur e 3).
Remove the saw fr om the shipping skid; discard any hold-down devices. Place the saw on the shop floor; secure the saw to the floor using mounting anchor s secured through four holes in the machine base. If the saw will be used to cut long pieces of stoc k, allow plent y of room for t he length of the stock .
Minimal assembly is required (see to Fig. 4), consisting of mounting the control box, motor,
pulley guard/cover assembly and motor drive belt. The mounting hardware is already in place
on the saw head. Loosen or remove the hardware, plac ing the components (listed above) in place and secure. For the drive belt, refer to the Drive Belt section on page 19.
Figure 3
Work Stop
A work stop 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. T he 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 br ac k et is moved in or out on the rod to establish the length of the workpiece.
Control Panel
The control panel is mounted on the top of the saw head. Refer to the Controls and Indicators section (page 9) f or a description of the controls.

Unpacking and Assembl y

Machine Setup
The cut-off saw has been pre-adjusted at the factory and sev eral test pieces hav e been cut to verify cutting accuracy.
Figure 4

Electrical Connection

Electrical connection must be made by a licensed electri cian. The wirin g methods and practices must comply with local electri cal codes.
The machine uses high voltage electrical power that poses a significant risk of serious injury or death if proper precaut ions are no t ob served
Connect the machine to the electrical power branch circuit (refer to the Wiring section on page 31). Observ e the following guideli nes when connecting the saw to the power source.
1. Make sure the saw is disconnected from the
electrical power branch circuit (trip the required circuit breakers or remove the required fuses).
8
2. Place a warning placard or tag on the service panel to prevent accidental electric al shock.
3. W hen installing the mot or power cord into a receptacle, make sure the plug is compatible with the receptacle.
4. When using hard-wired connections, connect the wires as shown i n the Wiring Data section.
5. Install the f uses or reset t he br eak er s.
Check operati on of t he saw.

Controls and Indicators

Control Panel

The operating controls for the cut-off saw are located on the control panel (Figure 5) and consist of the f ollowing c ontrols and indicat or s:
Coolant Pump Swit ch – turns the coolant pum p on and off.
Emergency St op Sw itch – pr ess to stop the dr ive motor. Note: A micro switch also stops the motor when the workpiece is cut and the saw head is complet ely down.
4. Loosen the drive motor locking handl e. Pivot the motor inward to slac k en the belt.
5. Select the speed using the placard on the cover. Put the V-belt in the pulley grooves of the pulley f or the desir ed speed. Refer to Figure 6 for belt locations and the speeds available.

Belt Position
Start Switch – press to start the drive motor. The saw head must be in the raised position.
Power Light – indicates that machine is plugged in and the outlet circuit breaker is turned on. T he machine does not need to be running for the power light to be on.
Feed Rate Control
thi s knob i s used to set t he
amount of downward f orce that is applied to the saw blade. The feed rate is proportional to the opening of t he valve. When set t o zero, the sa w head is locked i n the raised posit ion. Increasing the valve opening (countercloc k wise adj ustment) increases the feed rate; decreasing the valve opening (clockwise adjustment) reduces the feed rate.

Blade Speeds

The Model J-7015 horizontal cut-off bandsaw has four blade speeds. The dif fer ent speeds are obtained by changing the position of the motor drive V-belt on step pulleys. Change blade speeds as foll ows:
1. Disconnect the electrical power from the cut­off saw branch circuit to prevent accidental motor start-up
2. Set the saw head at the fully down position.
3. Remove the knob f rom the drive belt cover. Swing cover out and downward to expose the V-belt and pull eys.

Blade Selection

The cut-off saw is delivered with a saw blade that is adequate f or a variety of cut-off jobs on a variety of common materials. A 10-tooth, general-purpose blade is provided as standard equipment with the machine.
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 bl ade configur ations (toot h pitc h 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 toot h 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 to cut hard-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 workpiec e 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.
4. Keep the hydraulic cylinder needle valve in
the same position and begin a second cut on the same or similar workpiec e.
5. W hen the blade has completed about 1/3 of
the cut, increase the f eed r ate. Watch the chi p form ation until cutting is at its
most efficient rate and allow the saw to complete the cut (refer to Evaluating Blade Efficiency on page 10). The blade is now
considered ready for use.

Operations

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 hy draulic cylinder (Figure 7) and a feed rate control (Figure 5). The feed control cylinder resi sts motion in the downward directi on to control the feed rate. The control cylinder offers no resistance when raised upward.
The feed rate control knob (Figure 5) 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 slightl y open, the cylinder permits slow, or light, downward for ce. Opening the needle valve further incr eases the feed rate and applies mor e weight to the saw blade and workpiece.
Blade Break-in Procedures
New blades are very sharp and, theref ore, 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 specifi c blades on specific materi als. However, the following procedure will be adequate for break-i n of JET-supplied blades on lower alloy ferrous materials.
1. Clamp a secti on of round stock in t he vise. The stock should be 2 inches or larger in diameter.
2. Oper ate the saw at low speed. Start the cut with a very light feed rate.
3. When the saw has compl eted 1/3 of the cut, increase the feed rate sli ghtly and allow the saw to complete the cut.
The needle valve is adjusted until the saw is operating efficiently. The efficiency of operation is usually evaluated by observing c hip formati on. Blade efficiency is further described below.
