Recommended RPM range is 1070 - 2292 RPM At the speed of 1681 RPM, the recommended feed rate is 235340.00 - 504300.00 IPM Interpreting Results: - The maximum feed for roughing is the high rate - The starting feed for the best finish is the low rate - The starting feed for roughing should be taken from the middle of the feed range Formulas

Part 3: Feeds, Speeds and Chamfering Considerations - Practical Machinist

18/11/  · In grooving and especially in parting off operations, feeds and speeds are very critical for chip breakage, chip evacuation and tool life. As explained in the first post of this series, towards the center of the workpiece, at some point the spindle RPM cannot keep up with the requirement to maintain a constant cutting speed in SFM. As the

Everything You Need To Know About CNC Spindle Motors

A CNC spindle motor can achieve high speeds because they have a higher number of poles than other types of electric motors. They determine the number of poles by the number of winding pairs used in the stator. The more winding pairs you see, the higher the speed you can achieve. For example, the average car engine has four poles.

Fanuc > Spindle speed ~180% of commanded - IndustryArena

20/10/  · Spindle speed ~180% of commanded. Working on a Fanuc 21-T Lathe. Spindle speed override is set to 100%. No gearbox in the machine, serial spindle control (no voltage offsets) I command M3 S500, I get S873 (ish) - no idea why. Checked through the parameters and Gear ratio of spindle to position code is set at 1:1 in parameter 3706.
