Kaizen Project-Horizontal Band Saw[edit]

What the machine is and what sort of cutting it is good for

Black and White diagram on right showing all parts of saw, could use existing diagram

The Horozontal Band Saw in the shop is a Kalamazoo model H9AW, it can be used to rough cut metal or plastic (NO WOOD) stock to length. It has a cutting capacity of 9" Round and 9" by 13.5" rectangle at 90 degrees or 8" round and 8" by 8" rectangle when rotated to 45 degrees. The jaws jaws can open to 16" and it has a infinitely adjustable cutting speed between 62 and 390 FPM (REMINDER: only adjust when running) via a belt system.

Operation[edit]

controls

General usage procedure overview

-For more specific details see other sections 

-Make sure the machine is clean

-Lift handle and lock in position, finger tight on the lock is all that is needed.

-Load material and tighten in vice, Righty tighty lefty loosey, if loose the vice is free to slide by hand.

NOTE: No thin vertical material as it can damage the blade.

-Adjust blade holders as needed to clear stock, excessive clearance can introduce excessive blade wondering.

-Turn on coolant/ cutting oil if needed

-Place emergency stop button in the extended position.

-Turn on machine (press green button).

-Adjust speed as needed, see speed chart for general guide.

- Slowly turn head speed feed control to the left to let head down.

Ask shop manager about head speed, too slow caused the blade to rub and subsequently dull, to fast forces the blade through the material and can damage it. The head speed should be such that the blade is doing all the work.

-When the cut is done the machine will stop automatically.

- If done remove piece, return speed to default speed (turn on if speed adjustment is necessary) and follow cleaning procedure listed below.


Vice adjustment[edit]

To load stock lift up on the handle to open machine and tighten hydrolic controle (turn to right) to lock in place. Move vice as neeeded for part, may be tight, if excessive force required turn handle to the left to loosen and try again. Press vice against part and tighten as needed, make sure to load part so it won't come out. If needed use tip off block and stock stop to support end of material to keep it falling on the floor.

Troubleshooting[edit]

Pulled from existing mindworks document

Cutting fluid adjust

No coolant in the trough

- Talk to shop manager and mix appropriate coolant/cutting oil per instructions.  


The coolant is not pumping to the blade

-Turn the pump on, the switch is located beneath the vise hand wheel

Not enough coolant getting to the blade

-Adjust the coolant adjusting valves


There is a puddle of coolant beneath the motor

- Clean the shavings built up under the hood cover of the saw

Saftey[edit]

sheet on machine

find or rewrite/ update as needed existing safety sheet that is currently on the machine

Never operate the saw unless all guards and covers are in place and closed.

Stay clear of the machine while it is in operation.

Never insert any part of the body into the cutting area of the machine while it is operating.

Never attempt to adjust the stock stop while the saw is in operation.

Never adjust the guide arm while the saw is in operation

Never adjust the blade tension while the saw is in operation.

Always be sure that the blade is fully stopped before loading or unloading the machine.

Always be sure that the material to be cut is securely clamped in the saw vise before starting a cut. Loose material may be thrown from the machine and/or cause damage to the machine itself.

Always support long material from both sides of the work area to prevent the material from falling on the floor.

Never operate this machine unless you fully understand all of the controls and the operating cycles.

Never force a tool or attachment to do a job or operate at a speed is was not designed for.

Speed Chart[edit]

NOTE: THESE SPEEDS ARE AVERAGE FOR BI-METAL BLADES. IF YOU ARE USING CARBON BLADES, DECREASE THESE SPEEDS BY 50% FOR OTHER MATERIALS. TO INCREASE BLADE SPEEDS, TURN THE KNOB COUNTERCLOCKWISE. TO DECREASE BLADE SPEED, TURN THE KNOB CLOCKWISE. DO NOT EXCEED THE UPPER AND LOWER SPEED LIMITS. DO NOT TURN KNOB UNLESS THE MOTOR IS RUNNING.

Cleaning procedure[edit]

· Use the hand broom to brush all the shaving off machine onto the floor.

· Use the rag to clean oil and coolant.

· Sweep up shaving off the floor.

· Vacuum all remaining shavings (on and off machine).

· Lightly coat metal parts with WD40 to protect from rusting.

· Mop the floor if oil or coolant was soiled on the floor.

· Scan 360 degrees around machine repeat above steps if necessary.
