Description

On a milling machine, parts are created by removing material from a solid block (or workpiece) using a variety of spinning cutting tools.

A 3-axis vertical milling machine has a variable-speed vertical spindle and a heavy table that translates underneath it. A metal workpiece is clamped to the table and a cutting tool is held in the spindle. Cutting is done by moving the workpiece against the spinning tool, or by lowering the spinning tool into the workpiece.

A CNC milling machine operates by computer control. Motors are attached to the movement mechanics allowing the computer to make precision-machined parts automatically.

Safety Notes

Personal

		Eye protection required!

• Wear safety goggles. Eyeglasses are NOT safety goggles.

• Beware of flying chips. They are HOT and SHARP.
• Do not wear loose clothing or jewelry when operating the machine. Long hair must be tied back or covered.
• Do not wear gloves. Gloves can be drawn into a cut by the spinning tool.
• Do not remove chips from the cutting area with bare hands. Use a chip brush or a shop-vac.
• Always keep a secure, stable stance. Avoid over-reaching. Clean up oil spills immediately and avoid slipping. Keep the work area clear of trip hazards.

Machine

• Work must be clamped securely in a vise and the vise clamped tightly to the table, or, work must be clamped securely to the table.
• Always stay at the machine while it is running.
• Do not operate the machine if any unusual or excessive heat, noise, smoke, or vibration occurs.
• Make sure the spindle has come to a complete stop before changing tools or unloading the workpiece. Keep hands clear of the spindle start switch when changing tools.
• NEVER USE COMPRESSED AIR to remove chips from the work area.
• Remove all wrenches, chuck keys, and loose parts before turning on the machine.
• Before running machine the spindle should be rotated by hand to make sure it is clear for cutting.
• Make sure the cutter is rotating in the proper direction before cutting material.
• Always use sharp cutters that are in good condition.
