Sherline Electroless Boron Nickel Coated 3 Jaw Chuck 1040C

Description: Sherline Electroless Boron Nickel Coated 3 Jaw Chuck 1040C Sherline Electroless Boron Nickel Coated 3 Jaw Chuck 1040C Nickel Coated 3 Jaw Chuck 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 Jaw Options For those who have jobs where speed and ease of use are more important than maximum accuracy and want a chuck that is loose right from the start (No extra charge). Add the note “loose jaws” in an email to us when ordering. Alternately, soft (not hardened or machined) steel jaws are also available when you build your own chuck.

Standard chucks have darker markings than the coated chucks. Here, at Sherline Products, each of our chucks is laser engraved with a company mark, chuck size, and jaw location. During the laser marking process the laser removes a bit of the surface and darkens the material below. When chucks are sent out to receive the Nickel-Teflon finish the coating process changes the dark engraved markings to a noticeably lighter finish. There is also a subtle change in the color of the chuck, but in the absence of being able to compare them side by side, the most evident way to tell whether you have a coated chuck, or not, is to check the color of the laser markings.
