Tool Post - Grizzly G4015Z Owner's Manual

Tool Post

The Model G4015Z comes supplied with a 4 way
turret tool post. It is designed to accept up to 4-
1 ⁄ " tool bits. Other devices and holders may be
2
installed into the tool post and arranged as in
Figure 9. When more than one tool is secured
into the tool post, changing from one tool to
another is quickly done by loosening the lock
#
lever ( 5) and rotating the post to the desired tool.
A spring-loaded catch is installed below the tool
post. This allows motion in only
clockwise direction. The catch causes the tool
post to stop at the same rotational point for each
tool placement. This feature can be useful for
some types of machining setups. Please note
that the secureness of the tool post is not depen-
dent upon the catch. Thus, the tool post can be
positioned at any rotational location and properly
secured with the lock lever.
If using tool bits that require shimming, be sure to
use steel shims as opposed to aluminum or brass
shims. Soft shims may give, allowing the tool bit
to become loose!
When securing a tool bit into the tool post, always
remember these rules:
• Secure the tool bit with at least 2 bolts on the
tool post.
• Make sure the top of the tool bit is at the lathe
spindle center line or just below. The tailstock
center can be used as in Figure 10.
• Never extend the tool bit more than 2
thickness from the edge of the tool rest. i.e. a
3
⁄ " tool bit should only extend
8
tom of the tool rest. Less is best!
• Always use sharp tool bits.
