Centerless Grinding
Centerless Grinding
Centerless grinding is an effective method of removing stock from the outside diameter of round bar and tubing when tighter tolerances or better surface finishes are required.
We specialize in large diameter bar stock. Grinding can be added to any turned or cold drawn bar in sizes from 3/16″ (.1875″) to 16” diameter. The added grinding will ensure superior finish, tighter than industry standard size tolerances, and superior straightness.
We are able to provide size tolerances as stringent as .0002” total, with surface finishes of 12 Ra or better. Super polishing is also available using centerless grinding & polishing techniques, with surface finishes of 4 Ra or better. We also have the ability to centerless grind, measure, and provide charting documentation for other surface finish parameters such as Rz, Rmr, Rk, Rpk, Rvk, Rmax, and a host of others.
Northlake Steel can grind carbon, alloy, stainless, and tool steels; ceramic and laser clad coatings; and other exotic materials in lengths up to 75’ long.
