Central Machinery Horizontal Bandsaw

Members must complete the Metal Shop Safety Class before using this tool

Central Machinery Horizontal Bandsaw, located on the north side of the metal shop, next to the cold saw.

Safety

Universal Safety

• Be aware of your surroundings, especially when handling large materials.
• Do not approach anyone operating equipment. Stand patiently in their field of view.
• Use PPE, including filtration and eye protection, when handling dust or emptying dust/shaving containers.

Equipment-Specific Safety

The Metal Shop Safety Class is required to use this tool.

No special PPE is required to use this tool, but the general shop requirements of safety glasses and closed-toed shoes apply. Safety glasses may be found on a shelf on the back side of the Tormach enclosure.

Etiquette

If you are going to be spending a lot of time on the saw, write "horizontal band saw" in the title field of your Skedda booking so other metal shop users will know.

Use Case

The bandsaw is used for general-purpose metal cutting. It is suitable for bar, tube, and plate stock, but not for sheet stock. Used properly, it produces a fairly smooth, straight cut, which may be good enough for some applications, but you should not expect perfectly square cuts, so if precision is required, consider the bandsaw as a roughing step.

Materials

Acceptable Materials

All kinds of metal bar, tube, plate, or rod (properly secured) stock is acceptable. Stock should be thick enough to engage with three teeth of the blade at once. For sheet metal, use the Dayton Sheet Metal Machine instead.

Material Limits

This saw is capable of cutting large stock (slowly).

Consumables

The bandsaw uses pre-mixed blue coolant. You should find some between the bandsaw and the cold cut saw. If coolant levels are low and there's no pre-mixed coolant, please contact a steward.

Operation

Reserve time in Skedda under "Metal Shop - General". Using the bandsaw during another Metal Shop reservation (eg. "Metal Shop - Welding Area 1") is fine, but please don't monopolize the tool if others need to use it as well.

Setup

• Lift the blade to the vertical position. Turn the lowering knob to fully stopped and turn on the brake (lever is perpendicular).
• Place your material in the vise. Note that when you loosen the vise with the crank, it often doesn't move the jaw, so, you may have to manually move the movable jaw.
• For long material, support the end with the wooden support, or it is likely to come loose in the vise.

• Once your material is in place, lower the blade to the diagonal position. Because you set the brake, it should remain stationary there. Release the brake and turn the lowering knob to allow the blade to get close to your material so that you can line up the cut.
• Adjust the throat of the saw so that it is not much wider than it needs to be to clear the stock during the cut.
• Raise the saw back above your stock, set the brake, and turn the lowering knob to fully stopped.

Cutting

• Turn on the saw with the switch. Let the blade get up to speed. Open the coolant valve enough that there's a good flow of coolant along the blade, but not so much that there's a good flow of coolant all over the floor.
• Release the brake, and turn the lowering knob so that it slowly lowers.
• When the cut is finished, the machine will flip its own power switch to off.

Settings and Adjustments

Use the lowering knob to control the speed at which the blade descends. Harder material like steel should be cut more slowly than softer material like aluminum.

Cleanup

Universal Cleaning Guide

• Return the equipment to neutral.
• Sweep up any dust and debris around the tool, your table top, and the floor - both in the equipment area and your work area.
• Clear the floor of any tripping hazards, like power cords.
• Empty trash cans and dust collectors that are halfway full or more into the Asmbly dumpster behind the workshop.
• Leave the shop 110% better than you found it.

Tool Specific Cleaning Guide

• Use the metal shop general purpose shop vac to clean the machine and the area around it.
• If there's a lot of coolant on the floor, you can get most of it with the shop vac and wipe up the remainder with paper towels

Troubleshooting

Common Problems

Coolant spilling

The coolant rests in a blue reservoir under the machine. If coolant is leaking all over the floor, it's possible that the reservoir has shifted so that it is not directly under the drain. Please reposition it to catch the outflow.

If you are unsure, it is always best to contact a steward and fill out a problem report
