Bearings, Lappings & Centerless Grinding

While we are known for machining high precision components with the tightest of tolerances complete on the machine (+/- .0002”), sometimes an additional process is needed to get the length or outside diameter to the next level of high precision.

“We assisted an aerospace customer in reducing costs and improving precision and performance by developing a special lapping and grinding process that provides extremely tight tolerances on highly polished finishes (4 microinch or better) with uniquely contoured machined shapes not typically produced by screw machines.”

If you have any component requiring a high surface finish or extremely tight tolerance, we can economically meet those objectives with superior quality. Flat or cylindrical surfaces can be lapped to precise requirements for size, straightness, roundness, concentricity and finish with total tolerances of .0001” to .0002” measured and inspected with equipment reliably capable of measuring to the millionths of an inch (microns).

Our proprietary lapping and grinding processes can provide the most demanding applications with high performance tight tolerance components.  Improve the performance of your product with our high precision rollers, bearings or shafts.
 

  • Guarantee lengths to .00002” (20 micro inches) and diameters to .000003” (3 microinches or 3 millionths of an inch!). 
     
  • Even tighter tolerances can be had with an automatic secondary sort operation.
     
  • Get extreme Surface Finish of 2 microinches (.000002”) or better!
     
  • Get a customized profile with our grinding process to create precisely what your application needs!
