What is the recommended cutting speed range for bronze in fpm?

The recommended cutting speed range for bronze being 200 to 250 feet per minute (fpm) is based on its material properties, which allow for efficient machining. Bronze is a non-ferrous metal, known for its excellent machinability and wear resistance. These properties enable faster cutting speeds compared to ferrous materials.

When machining bronze, using the right cutting speed optimizes tool life and improves surface finish. The range of 200 to 250 fpm is derived from empirical data gathered from machining practices and is designed to balance cutting efficiency and tool wear.

This speed allows for effective chip removal while minimizing the risk of damaging the workpiece or the cutting tool. Factors like tool material, geometry, the specific type of bronze, and cooling methods can also influence the preferred cutting speeds, but this range serves as a solid general guideline for machining bronze effectively.
