Safety on Milling Machines

Milling machines require special safety precautions while being used. These are in addition to those safety precautions described in Chapter 1.

  • Do not make contact with the revolving cutter.

  • Place a wooden pad or suitable cover over the table surface to protect it from possible damage.

  • Use the buddy system when moving heavy attachments.

  • Do not attempt to tighten arbor nuts using machine power.

  • When installing or removing milling cutters, always hold them with a rag to prevent cutting your hands.

  • While setting up work, install the cutter last to avoid being cut.

  • Never adjust the workpiece or work mounting devices when the machine is operating

  • Chips should be removed from the workpiece with an appropriate rake and a brush.

NOTE : Chip rake should be fabricated to the size of the T-slots (Figure 8-2).

  • Shut the machine off before making any adjustments or measurements.

  • When using cutting oil, prevent splashing by using appropriate splash guards. Cutting oil on the floor can cause a slippery condition that could result in operator injury.
