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.
