Do I need speed above 60 IPM on a hobby mill
With the original Bosch drives, my 145v motors, etc, the mill was
capable of 200 IPM rapids. Right now I have a 70v power supply with 30A8 drives and the top speed is 60-70 IPM. My question is how much am I losing, in reality, but having faster top speed. My feeling is not much, but I want to know. This is not an entirely idle question, as I could install drives that match motor voltage (30A20AC or 25A20AC or some such). They would use 120 VAC as power source. So, would I see any improvement in anything valuable with higher top speed or no? i |
