Centerless Form Grinder: PG-912 DG

The PG-912DG Enclosed Centerless Form Grinder uses a 12″ wide work wheel and servo motors to reduce setup times, increase throughput, and maintain tighter tolerances. The enclosed design features a simple touch­ screen HMI, and remote connectivity and data collection. Combined, these functions help to generate more uptime and produce higher quality parts, something every manufacturer strives to attain. Common applications include applications include ceramic spools, carbide pins, deodorant balls, golf balls, pen nibs, drumsticks, composite spindles, contact lens blanks, check valves, frac balls, fuses, insulators, and many more.

Key Features
  • 12″ wide work wheel allows manufacturers to grind more parts per In testing, throughput increased throughput by as much as 30%.
  • Interlocks prevent opening the enclosure while the grinder is running.
  • Servo motors automatically adjust the oscillating regulating wheel to the pre-programmed position, reducing setup time.
  • Precise positioning maintains tight tolerances and improves sphericity. In testing, a Cpk two times greater than the existing process was achieved.
  • The thick granite machine bed provides enhanced rigidity, as well as thermal and vibratory stability, maintaining a high-quality part.
  • The machine software interface was developed to allow an unskilled operator to run multiple high precision machines simultaneously.
