Centerless Grinding
Provides some of the highest stock removal rates, combined with high through put line speeds & precision tolerancing, of any centerless grinding technology available in the market today.
Acme’s Centerless Grinding Technology
One of the key advantages of centerless grinding technology is the utilization of the most advanced coated abrasive belt technology available.
High production throughput for DOM tubing, steel bars, titanium & inconel rods and tubing can be achieved. Our line of centerless grinders and polishers use advanced coated abrasive belt technology combined with either single or multiple head configurations, allow for a single pass operation, removing maximum stock, producing a low surface finish, at high output. The rate of stock removal and surface finish achievement is dictated by the diameter of the material and the line speed of the material being processed.
Centerless Grinding Capabilities
- DOM tubing up to 12” O.D. (300mm)
- Bar stock up to 8” O.D. (200mm)
