How Do I Machine Composite Bearings?

From Polygon Company
 

 
Q: "How do I machine Composite Bearings?" A: The most common type of fabrication customers have questions about is how to cut composite bearing materials. Depending on how critical the squareness (perpendicularity) of the cut needs to be, on smaller bearings a standard chop saw can be used. The typical tolerance for perpendicularity is 0.005" off the chop saw. Polygon recommends a diamond plated blade tipped with 120 grit diamonds. A rougher grit (80) can be used but that will often times result in a poorer surface finish. Polygon also recommends having the blade turning at between 1500-3000 RPM with a water-soluble coolant flooding the tube as it is being cut. This coolant will allow the tube to be cut without burning the end, generated during the cutting process.
Products & Services
Plain bearings and sleeve bearings (also referred to as bushings or journal bearings) are used to constrain, guide or reduce friction in rotary or linear applications. They function via a sliding action. Search by Specification | Learn more about Plain Bearings and Sleeve Bearings
