Shaft speed is the key to increased productivity???

Of course, High Speed Machining has brought major benefits to manufacturers and will continue to do so. However, with so much talk about high spindle speeds it is tempting to retrofit for as high a shaft speed as possible, but there are more things to to be considered in selecting the right spindle. For example, on KTM type routing machines (gantry mills), you can:

• Routinely achieve a 3- to 4-fold machining time productivity increase.
• Obtain much greater thermal stability and thus accuracy.
• Produce better surface finishes than you have ever seen on the machine.
• Benefit from a reliability you have only dreamed of.

All by running as low as *9000 rpm on stock removal operations. Yes, the same speed as the original spindle's maximum speed/power point. So why invest in a high speed system, which is too fast for your machine axes, and, lacking robustness, puts your productivity and payback at risk?

In any case, a 3 to 4-fold productivity increase gives you a big enough swarf management problem as it is. Don't get caught out!

* Base speed of a 16000rpm system, i.e. the highest speed at which maximum torque is available
