≈ 380 rpm Note: since applying oil manually, scale the speeds back to 60%, so N ALUM ≈ 570 rpm and N STEEL ≈ 230 rpm (final answer) . Note these are MAXIMUM values and lathe chuck safety must take precedence; spinning the lathe chuck at 570 rpm is about the upper limit of what we safely do in the lab, so for smaller workpieces, do not exceed 600 rpm, regardless of the calculation results.
Sep 29, 2019· The NOVA Comet II has the most impressive RPM speed range of all the wood lathes we examined. It can move from just 250 RPM when working on a simple table leg all the way up to 4000 RPM for making intricate designs and pieces. You can use the simple pulley system to easily move from a lower speed up to a higher one.

The primary factor in choosing feed and speed is the material to be cut. However, one should also consider material of the tool, rigidity of the workpiece, size and condition of the lathe, and depth of cut. For most Aluminum alloys, on a roughing cut (.010 to .020 inches depth of cut) run at 600 fpm.
The turning process requires a turning machine or lathe, workpiece, fixture, and cutting tool. The workpiece is a piece of preshaped material that is secured to the fixture, which itself is attached to the turning machine, and allowed to rotate at high speeds.
