Superfinishers Microfinishing Frequently Asked Questions
Many different terms are used for Microfinishing. Polishing, Superfinishing, finishing, and mirror finishing, also sanding, linishing or just finishing.
1) What is Microfinishing?
Microfinishing is a finishing process using Microfinishing Film to achieve target surface finish requirements, every time.

Microfinishing quickly and efficiently achieves any Ra, Rz, Rmax, Bearing Ratio Area and other surface finish parameters that might be specified.

Microfinishing is the most consistent method of obtaining these surface finishes.
2) How does Microfinishing work?
The Microfinishing process utilizes a precision-coated abrasive called Microfinishing Film. Microfinishing Films are available from 0.05 micron to 180-micron mineral size. (Note:  That is 60 mesh up to 10,000 mesh) The micro abrasives are applied to the workpiece in a constantly indexing fashion, therefore all areas of a large roll are always in contact with new fresh abrasive.
The micron grade of abrasive used determines the surface finish.
3) What materials can be Micro finished?
Microfinishing can finish any material: from soft rubber and urethane to HVAF/HVOF hard tungsten carbide. Stainless steel, copper, chrome plating, ceramic coating and cast iron
4) What types of parts or rolls can be Microfinished?
Virtually any size part can be Microfinished. Companies are finishing fuel injector parts, transmission components, shock absorber rods, valve stems and many other small components. Paper mills are Microfinishing rolls that can be up to 5-meter diameter and 14-meter long. Exceptionally large Copper foil drums and Yankee dryer drums are also finished using this process.
5) Can I afford to implement Microfinishing into my production process?
If a very consistent surface finish is required on your parts, this process is the most economical method. It is productive, cost efficient and easy to operate.
6) What types of Microfinishing machinery are available?
Any industry can use Microfinishing in their operation. Microfinishing attachments can be mounted on any lathe or cylindrical grinder.

Many styles of production machines are also available, including thru feed and plunge Centerless, center driven, and turnkey roll finishing and custom machines built to a customer’s specification.
7) Is this Microfinishing a recent technology that is still in the experimental stage?
Microfinishing has been used for over 30 years. The automotive industry has been using this process to MicroFinish camshafts and crankshafts for many years. Steel mills and paper mills have been Microfinishing rolls for over 20 years.
