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 a blank. 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…allowing Double Disc Grinding to achieve tolerances superior to Blanchard Grinding or flycutting. Additionally, Double-Disc Grinding provides surface finishes of up to 16 Ra on aluminum and up to 8 Ra on ferrous alloys.
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.
Thickness Consistency… Ideal For Stacking & Spot Facing.
Double-Disc Grinding provides optimum part-to-part parallelism and flatness consistency, making it ideal for blanks to be stacked or spot-faced in machining operations. Parallelism and flatness tolerances are held consistently even on large, hard-to-machine blanks.
High Volume Grinding – or 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.
11 Double-Disc grinders provide premachining time savings of up to 50% by grinding both sides of a blank at the same time. Part-to-part dimensional, parallelism, and flatness tolerances are held consistently.
