Flat honing is precision fine-grinding is a process that was introduced in the late 1980’s. This process achieves a superior surface finish when compared to conventional grinding, but also provides faster stock removal than traditional lapping processes. 

The achievable tolerances are based on the physical characteristics of the individual parts.  Typically we can achieve 

  • Size: ±.000050″ 
  • Flatness: .0001″
  • Parallel:  .0001″
  • Finish: 8 Ra

This type of finishing is best suited to products requiring a high stock removal rate, but where traditional grinding would provide too rough a surface finish, or where precise tolerances are required. 



Listed below are some of our typical applications for precision fine-grinding:

  • Metal Injection Molded parts
  • Powdered Metal (Sintered) parts
  • Seals
  • Valve Components
  • Carbides and Cutting Inserts
  • Precision Piston Rings
  • Automotive sensing devices
  • Hydraulic Gear Pump Components
