Enhanced Form Grinding – Spherical & Cylinder Components | Glebar PG-912DG
Challenge
Manufacturers producing spherical and cylindrical components have traditionally relied on lathes and hydraulically powered form grinders to shape parts to their required geometry.
Lathes form parts one at a time from bar stock, limiting throughput and requiring skilled technicians for complicated, labor-intensive setup. Manual operation of gears and levers to control cutting-tool position makes tolerances highly dependent on operator skill, resulting in inconsistent surface finishes that are difficult to replicate between runs.
Hydraulically powered form grinders improve throughput by processing multiple parts per cycle, but they still require skilled setup involving multiple microswitches. Regulating wheel speed fluctuates as the hydraulic system warms up, compromising tolerance control. Both machines feature exposed work areas, increasing the risk of operator injury.
Process
The Glebar PG-912DG Enclosed Centerless Form Grinder addresses the limitations of conventional form grinding with a 12-inch-wide work wheel, servo motors, and an enclosed design that together reduce setup times, increase throughput, and maintain tighter tolerances, while providing a safer, cleaner work environment.

The Glebar PG-912DG Plunge Grinder’s 12-inch-wide work wheel and servo motors deliver a 30% increase in thruput and a Cpk two times greater than the existing processes. Servo-controlled positioning automatically adjusts to programmed settings, significantly reducing setup time. The fully enclosed design with integrated interlocks and mist collection provides a safe, clean work environment, while built-in remote diagnostics and data collection support production monitoring and informed decision-making on the shop floor.
