Our versatile precision grinding machines are workhorses which require a smaller footprint than similar machines yet excel in demanding high production environments where the name of the game is high volume at low cost. Glebar engineers can tailor an automotive precision grinding turnkey solution, complete with a series of pre- and post-grind inspection steps, ensuring the product going into the Glebar machine meets the requirements of the final ground product with guaranteed accuracy.
Castle Nuts, also referred to as Castellated Nuts, are used for applications in aerospace and automotive markets where the nut cannot loosen. A cotter pin or safety wire is inserted through a cross-drilled bolt extending through the opposing slots to mechanically prevent the nut from loosening. Without the Castle Nut, the nut would separate from its shaft potentially leading to catastrophic results.
Slotting Saws, Abrasive Grinders, Wire EDM, and Sinker EDM are popular mechanical and abrasive processes used for slotting Castle Nuts. The slotting operation requires three cuts per part, cutting two slots per pass. Parts are loaded manually.
Typical saws and grinding processes require frequent wheel dressing or saw changing, dramatically reducing productivity and throughput. Current manufacturing processes can distort the slot, damage the thread, or deform the thread. Secondary deburring or re-tapping is often required after slotting. This results in increased scrap rates, increased cycle times, and reduced throughput.
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.
Challenge: To design a fully automated turnkey feeding and inspection solution, integrated into to a Glebar GT-610 Thrufeed Grinder that ensures a one hundred percent defect-free product that is ground to a minimum 1.7 CpK and packaged hands-free.
Challenge: To auto thrufeed grind metal valve seat components which are used in the automotive industry. The customer needed a system which could accurately grind and gauge 3,000 parts per hour. The width and nonsymmetrical geometry, would be the most difficult challenge engineers would face in devising a successful staging and feeding process as they are not able to line and stack up onto a traditional conveyor without falling over.
Challenge: A tier one automotive fastener supplier needed to grind bolts for a major automotive company automatically at high volume, with a high degree of precision.The customer’s existing process was outsourced and was running one part at a time, resulting in a higher cost for our customer.In addition, quality and consistency of the components post grind was an issue.
Challenge: To thrufeed automatically thru feed grind an automotive component and achieve a 1.2 Rz surface finish
