Nov 16, 2012 · Optimizing capability will require several gear ratios, as any given cut in steel requires ~4-5X the power required to make that same cut in aluminum. If you optimize for steel, you'll have a machine with lots of low-RPM torque (achieved through gearing) but it will likely be near useless for cutting aluminum, and vice-versa.

The spindle speed must be set so that the tool will be operating at the correct cutting speed. To set the proper spindle speed, we need to calculate the proper revolution per minute or RPM setting. We stated earlier that cutting speed or surface speed would change with the size of the tool.

It's not Horsepower, It's Torque! This tool entry is when the torque curve on your CNC machine is the most important. Older CNC machines where designed to quickly reach peak torque between 1200 - 3000 RPM and then drop off. Newer, high speed machining centers hold constant torque.

Start by retrieving the value for unit power required for this application. Unit power is defined as the horsepower required to remove one cubic inch of material in one minute. From table 17.2-3 of the Handbook one finds two values for the estimated unit power (P) required when turning (boring) aluminum.

Nov 26, 2017 · Milling aluminum (6061) doesn't require nearly as much torque as milling steel but more torque is usually better than less. The higher the spindle speed, the more power you need to maintain decent torque. This is why large high speed CNC mills have crazy huge 40hp spindle motors (or more). Take a look at the Hass mini mills for an example.

Mar 21, 2009 · But it has 33ft lb of torque at 1,200 RPM. I don't know if the Mini-mill motor is the same or equivalent to the VF-0 motor. If they ARE similar - that 7.5 HP is developed at 1200 RPM and would probably fall precipitously as the RPM increases. You'd need to get a torque curve chart from Haas to see what your horsepower would be at other RPM speeds.
