Machinists Tips - Milling

When face milling, use positive geometry cutter bodies. Quadrant Service & Support provides guidance when milling plastics.

Quadrant Service & Support provides the following guidance when milling plastics.

Milling Tips

Milling

Sufficient fixturing allows fast table travel and high spindle speeds when end milling plastics. When face milling, use positive geometry cutter bodies.

Milling Tips

Climb milling is recommended over conventional milling.
