Professional flat honing services are precision fine-grinding processes that were introduced in the late 1980s. This process achieves a superior surface finish when compared to conventional grinding, but also provides faster stock removal than traditional lapping and honing processes. 

The achievable tolerances are based on the physical characteristics of the individual parts. Typically, our precision grinding services 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, professional flat honing services can achieve the precision necessary for even the most minute specifications. 

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
