MAIN APPLICATIONS
Superfinishing systems are commonly used for optimising surfaces of rolls and other cylindrical parts. Long super-abrasive strips (with tails) and/or Diamond Lapping Film are used for polishing and finishing hard brittle materials such as Thermal sprayed coatings like HVOF sprayed carbides and ceramics.
This system provides predictable, consistent (over the entire surface) and repeatable finishes. It improves the surface structure which can easily be compared to levels reached by honing or lapping.
Another important advantage is the ability to achieve the desired surface texture. From a highly reflective finish and low Ra value, to a specific surface roughness for friction grip & ink, water or oil retention. During the constant use of these rolls, they tend to lose this surface roughness and become “polished” during use. In this way rolls can be refurbished many times before fully being stripped and recoated.
Superfinishing tape has a speed controlled slow movement over a pressure controlled rubber contact roll. This contact roll has an oscillating movement. When the workpiece is rotating in the opposite direction, the superfinish machine traverses along the workpiece; these combined motions create a cross-hatch pattern with a high percentage of plateaus and some grooves. Giving the desired surface finish and cylindricity.
