Enclosed Centerless Form Grinder

Glebar has launched the PG-912DG , the latest model in the Plunge Grinder series. It is designed to increase throughput, reduce set-up times and achieve tighter tolerances. Additionally, it provides better integration to gauges, automation and remote service diagnostics.

At the core of the PG-912DG is a 12" wide work wheel. The wider work wheel allows manufacturers to grind more material or parts per cycle. In testing, Glebar's engineers were able to increase throughput by as much as 30%.

Glebar pairs the wider work wheel with an oscillating regulating wheel powered by servo motors to reduce set-up time and improve sphericity. The slides can be programmed to finite positions through a touchscreen HMI. When an operator selects a job, the servo motors automatically adjust to programmed positions, which reduces set-up time.

"The position of the regulating wheel is critical to the accuracy of the grind. Using servo motors to position the regulating wheel creates greater repeatability in the grind and can maintain a tighter tolerance. In testing, we were able to achieve a Cpk two times greater than the existing process," said John Bannayan, CTO.

In this specific application, a stainless-steel hopper automatically drops parts into the feeder channeling them into singular stations on the plunge grinder. Within a 14 second cycle, up to 12" of parts can be ground simultaneously. The servo powered oscillating regulating wheel assembly rotates the balls randomly, improving sphericity. An interlocking safety enclosure and mist collector provide a safe and clean work environment. The granite machine bed helps to provide enhanced rigidity as well as thermal and vibratory stability. The high speed multi-axis control system can expand the machine functionality and includes the ability to remotely diagnose the machine and gather production data for reporting.
