Flat Honing of a Tool Steel Part

The customer provides laser-cut tool steel parts with a thickness that varies by +/- 0.001” from the nominal.  The parts are flat within 0.003” and parallel within 0.0015”.

Utilizing a dual lapping machine and free abrasive machining, we flat hone both sides of the parts to the specified thickness of +/- 0.0003”, flatness within +/- 0.001”, parallelism within +/- 0.0002”, and a surface finish of 32 Ra or better.

In addition to the parts, we provide statistical data on the thickness and flatness to illustrate the part conformance and our capability.
