Tolerances:

We offer our services and our expertise to finish your parts. We can take your machined part and hold typical tolerances of:

  • (.0001" and a four micro inch finish)
  • For extremely critical metal ball applications, we can hold tolerances (below .000005" and one micro inch surface finish)
  • We can maintain traceability throughout the process

Many times, parts are failing due to poor geometry or inferior tolerances. We remedy this through our proprietary processes.
