What is Double-Disc Grinding ?
August 25, 2019
Double-Disc Grinding is a highly efficient grinding method that reduces premachining costs up to 50% and provides dimensional tolerances, parallelism, and flatness to ±.0002″. Double-Disc Grinding uses two opposing abrasive wheels to simultaneously grind two sides of the material. In one operation, equal amounts of material are removed from both sides. Grinding two sides of a part at the same time provides greater control of dimensional tolerances, flatness, and parallelism.
Internal stress relief is another Double-Disc Grinding benefit. Simultaneously removing equal amounts of stock from two sides of a blank reduces residual stress. Less residual stress improves part stability during secondary operations and final machining.
Supports Stacking & Spot Facing
Double-Disc Grinding provides optimum part-to-part parallelism and flatness consistency, making it ideal for material to be stacked or spot-faced in machining operations. Parallelism and flatness tolerances are held consistently even on large, hard-to-machine parts.
High Volume Grinding
Automated Double-Disc Grinding furnishes cost effective thickness sizing for small parts such as fine blanked stamped, die cast, and sintered metal parts. Through automation, the production costs of large quantity runs are significantly reduced.
