Challenge: To devise a new process for an automotive component manufacturer to automatically grind and gauge pinion shafts for differentials. The shafts are made of hardened steel. The Customer is looking to expand their automotive manufacturing portfolio by bringing large volume production in-house.
Solution: Glebar’s GT-610 Thrufeed Centerless Grinding System was configured with a bar feeder and enclosure for safety. The operator simply loads the oriented parts into the hopper to initiate automatic feeding to the grinding system. Stock removal was achieved in one pass with a diameter tolerance of .00064” maintained with a 2.0 CPK.
When a requirement exists to thrufeed automotive parts in a high production environment using a high level of automation, the versatile GT-610 grinding system significantly out-produces alternative processes. The GT-610 is built on a solid granite base with independent slides and a template tracing dresser. HMI controls allow one-touch operation and the use of an integrated digital micrometer which allows the ability for offline gauging with measurement data to be sent back to the machine for automatic adjustment to compensate for any wheel wear.
The GT-610 Automated Infeed/Thrufeed Centerless Grinding Machine can be custom fitted with automation. This system is the ideal option for when infeed applications do not require a CNC dresser and for the vast majority of thrufeed applications. The GT-610 excels at hard metals and composites, producing carbide blanks, spools, bushings, and engine components such as automotive fasteners and valve lifters. It can also effectively size down metal bars.
