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.

- 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.
