Apr 09, 2015· I purchased a used 1324 Granite machine about ten years ago. I think it was built new in the late nineties. The machine sees very little use (8-40 hours a year) and is in great condition. However for the second time in the last three years, I have lost (burned out) the motor control board, when turning large diameter work pieces at low rpm.

My small home made milling machine needed a new spindle. After searching and pricing a few I decided nothing really fit my needs and I decided to build it. This is the design inspired by a few threads on RCGroups and CNCZone. It uses three angular contact high speed spindle bearings and the chosen motor should allow up to 30,000 RPM.

Jan 18, 2018· Hello all- I have a bridgeport-style milling machine with head similar to J-Head, but without back gearing. The current motor on the machine is 1750 RPM 120/240 single phase, and I want to go with a variable speed setup using VFD and 3-phase motor (have done a lot of reading on this site on that in general).
Mar 15, 2010· Translate that to a 20 HP milling machine and it's 20 cu in/min The tool used wether HSS or Carbide does not really mater much, Carbide just runs faster and the metal removal rate is higher. RPM depends on tool diameter and material being cut and feedrate depends on the strength of the tool. Get out your Machinerys Handbook...

which enables us to see how the Attritor fits into the family of mills. For example, ball mills use large media, normally 1/2" or larger, and run at a low (10-50) rpm. The other mills, such as sand, bead, and horizontal, use smaller media from 0.3mm to 2mm, but run at a very high rpm (roughly 800-1200).

We like Constant Torque Because of the unique geometry, our tools perform best under constant torque. Take a look at the torque curve for your CNC machine. If you have a 10,000 RPM spindle motor and the torque drops from it's constant peak at 8200 RPM, then 8200 RPM would be the maximum RPM.
