This chuck is identical to P/N 1040 except for an electroless nickel boron coating that has been applied to help prevent wear and corrosion. This special coating has been applied to all external and internal surfaces of the chuck (except for chuck jaws), significantly improving the life of the chuck. This chuck also opens and closes more smoothly due to the lubrication properties of nickel boron. Other benefits and features of the electroless nickel boron coating include the following:
- Ductile plating with columnar structure
- Harder than any other nickel-based coating
- Coating uniformity that eliminates post-plate grinding (or burnishing)
- Wear properties overall superior to hard chromium
Hardness (68-72 Rc)
- Low coefficient of friction (.044) Teflon™ is .04
- Uniform coating thickness up to .004”
- Accepts dry film lubricants
