Double Disc Grinding
Double disc grinding is a highly efficient grinding method that reduces pre-machining costs up to 50% and provides dimensional tolerances to ±.0002″, parallelism to .0002″, and flatness to .0002″. Double disc surface 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, making this a very cost-effective option within production grinding services.
Our equipment will handle most any configuration of parts and is also capable of handling flat stock up to 30′ in length. This makes it suitable for a wide range of production grinding services. U.G.C. is an excellent source for large production runs when cost effectiveness is important. In addition to thrufeed and paddle-type double disc surface grinding machines, U.G.C. also uses chain hold-down grinders for bushings, pins, and shafts. Gun feed grinders are capable of handling odd-shaped items. Flat bar stock is ground on widths and thickness in long lengths. We now have 12 machines available for both general and specialty production grinding services.
Grinding two sides of a part at the same time provides greater control of dimensional tolerances, flatness, and parallelism, allowing double disc surface grinding to achieve tolerances superior to Blanchard grinding or fly cutting. Additionally, double disc surface grinding provides surface finishes of up to 16 Ra on aluminum and up to 8 Ra on ferrous alloys.

Internal stress relief is another benefit of double disc surface grinding. 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. This makes it ideal for flat and parallel surface grinding applications.
High-volume grinding or automated double disc surface 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, especially for grinding services for chrome-plated tubing and high-tolerance ID/OD grinding applications.
