TECHNICAL INFORMATION
CHUCK JAWS

Pointed Soft Jaws
Pointed Soft Jaws are ideal for small-diameter parts, as well as large-diameter parts, because the point allows closing nearer to the center of the chuck. Standard steel material can be case hardened after machining, or left soft. Optional aluminum material reduces surface marring, ideal for chucking on finished surfaces.

Square-Nose Soft Jaws
General-purpose blank top jaws. Standard steel material can be case hardened after machining, or left soft. Optional aluminum material reduces surface marring, ideal for chucking on finished surfaces. Choice of standard height or extra high.
PIE-SHAPED SOFT JAWS
 |
For thinwall parts |
For non-cylindrical parts |
Full-grip jaws for increased surface contact on large-diameter or thinwall parts, to prevent distortion and marring. Also ideal for fixturing non-cylindrical parts. Choice of standard height or extra high. Cast aluminum material is standard, with steel or cast iron available as an option. Steel jaws can be case hardened after machining, or left soft.
HARD JAWS
Two-Step
Reversible Hard Jaws
Most-common hard top jaws with two steps on which to rest parts. Also reversible for through-feeding barstock. Jaws have diamond-point gripping serrations whenever possible.
Single-Step
Reversible Hard Jaws
Available for some chucks. Similiar to the hard jaws at left, but with only one locating step.
Non-Reversible Hard Jaws
Non-reversible hard jaws made for some high-speed chucks.
