Can I use PreciseBits solid carbide end mills on any milling machine?
Carbide grade have improved substantially during that past decade. Higher transverse rupture strengths, more resistance to shattering and a greater understanding of the role of each chemical component in the mix have resulted in the introduction of solid carbide tools in applications that once demanded high speed steel with exotic surface treatments. Nonetheless, the stability of your machine and the way your have it set up are very important. Consider the following items (in order of importance): • Spindle Runout (TIR) – should be less than or equal to 2% of the tool’s diameter (absolute maximum). • Spindle axis to table orthogonality- should be at 90 with no more than .1 variance. • Spindle Peak RPM – most of our tools require a minimum of 15,000 RPM under maximum anticipated load. • Collet Retention Force – the collet must not let the largest diameter tool you will use slip under maximum anticipated load. • Appropriate Feed Rates – motor drivers should be capable of moving the bit (
