Frequently Asked Questions

What is Microfinishing?

Microfinishing (superfinish) is an Abrasive Process that allows our Customers to:

  1. Obtain very Consistent Surface Finishes - Predictable and Repeatably
  2. Achieve virtually any Surface Finish - Ra, Rz, Rt, Rpk, Bearing Area
  3. Remove Amorphous Layer (Thermally Damaged Surface Layer caused by Grinding)
  4. Eliminate Microscopic Burrs left by the Grinding Operation
  5. Remove Defects from the Grinding Operation - Traverse, Chatter, Fishtails
  6. Improve Geometry - Roundness, Flatness, etc
  7. Improve Efficiency
  8. Reduce Friction
  9. Reduce Noise

What Materials can be Microfinished?

Microfinishing (superfinish) can be used on virtually any material. In fact, the more difficult a material is to finish with other processes, the easier it is for OUR process. Microfinishing (superfinish) is used on Tungsten Carbide, Ceramics, Head Coating, Chrome Plating, Bearing Steel, Forged Steel, Chilled Iron, Cast Iron, Soft and Hard Rubber, Copper, Aluminum, Stainless Steel and many other materials.

What Types of Parts are being Microfinished (superfinished) with this Process?

This can be a very long list. Parts as small as a 3/16" dowel or as large as a yankee dryer drum, which can be 20 feet in diameter, are being microfinished (superfinished). Engine and transmission components, hydraulic and pump parts, shock absorber rods and struts, compressor parts, steel mill work rolls, paper machine rolls, copper foil drums and a large variety of other parts are being microfinished.

Is it Expensive to Microfinish?

Not at all. The abrasive costs are minimal and our customers normally see large savings as a result of a decrease in production time and labor costs. Another cost savings results from the quality and consistency of a microfinished surface. No more rejections or questionable quality.

Are Microfinishing Machines very Sophisticated and Difficult to Operate?

Absolutely not. The microfinishing (superfinish) process is a very simple technique and all of our machines are designed and built to be very user friendly. Customers have the ability to train operators in a matter of hours on how to operate our equipment. There is no more "art" as there is in operating a sophisticated grinder.

What Choices do I have on Machine Designs?

There is a machine design for every application and every budget. We have microfinishing attachments that can be mounted on an existing lathe or grinder. These machines have all of the capabilities of our production machines, but are used by customers finishing large rolls and those who don't have high productions requirements. Our production machines include centerless, vertical spindle, camshaft, and crankshaft designs. The production machines can be ordered with minimal automation of the high degree of sophistication required in fully automated production lines and "lights off" operations.
