Compound Rest Four-Way Tool Post

The compound rest handwheel has an indirect- read graduated scale. This means that the dis- tance shown on the scale represents the actual distance the cutting tool moves. The base of the compound rest has another graduated scale used for setting the cutting tool to a specific angle.

To set the compound rest at a certain angle:

The four-way tool post is mounted on top of the compound rest and allows a maximum of four tools to be loaded simultaneously.

Each tool can be quickly indexed to the workpiece by loosening the top handle, rotating the tool post to the desired position, then re-tightening the handle to lock the tool into position.

2.rotate the rest to the desired angle, as indicated by the scale at the base,

then retighten the two hex nuts.

Tip: The first time you set the angle of the compound rest for cutting threads, mark the location on the cross slide as a quick refer- ence point. This will allow you to quickly return the compound rest to that exact angle the next time you need to cut threads.

Over-extending a cutting tool from the post will increase the risk of tool chatter, breakage, or tool loosening during operation, which could cause metal pieces to be thrown at the operator or bystanders with great force. DO NOT extend a cutting tool more than 2.5 times the width of its cross-section (e.g.,

2.5x 0.5" = 1.25").

2.Firmly secure the cutting tool with at least two tool post bolts.

3.Check and adjust the cutting tool to the spindle centerline, as instructed in the next subsection.
