PG-912DG Enclosed Centerless Form Grinder

The Glebar Advantage

Glebar’s 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. Our engineers didn’t stop there, adding an enclosed design, 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.

Introducing the PG-912DG

  • The PG-912DG Enclosed Centerless Form Grinder is the latest version of our PG-9 Plunge Grinders series and features a 12” wide work wheel.
  • The thick granite machine bed provides enhanced rigidity, as well as thermal and vibratory stability, maintaining high-quality parts.
  • Fully enclosed with interlocks and a mist collector to provide a safe and clean work environment.
  • Servo motors provide faster setup and greater accuracy, achieving a Cpk two times greater than the existing process.
  • Provides better integration to gauges, automation, and remote service diagnostics.
  • Glebar’s plunge grinders are designed to grind parts as small as 0.050" to 4" diameter on the same machine.
  • Chances are, that in every household, you will find a component that was ground on a Glebar Form Grinder. Examples of grinding applications range from fuse bodies, golf balls, check valves, electric insulators, carbide rods, and deodorant balls.
The wider work wheel helps to increase throughput by as much as 30%.

PG-912DG Highlights

12” Wide Work Wheel Improves Throughput

12” Wide Work Wheel Improves Throughput

At the core of the PG-912DG is a 12” wide work wheel. The longer 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%.

Clean and Safe Working Environment

Clean and Safe Working Environment

Fully enclosed with interlocks and a mist collector to provide a safe and clean work environment. The interlocks prevent opening the enclosure while the grinder is running.

Precise Positioning Maintains Tight Tolerances

Precise Positioning Maintains Tight Tolerances

Operators can quickly call up a job using the touchscreen HMI, and the servo motors will automatically adjust the oscillating regulating wheel to the pre-programmed position, reducing setup time. This precise positioning enables the PG-912DG to maintain tight tolerances and improve sphericity. In testing, Glebar engineers achieved a Cpk two times greater than the existing process. The thick granite machine bed provides enhanced rigidity, as well as thermal and vibratory stability, maintaining a high-quality part.

Intuitive HMI Controls

Intuitive HMI Controls

The control software is entirely developed at Glebar and is fully customizable to address your application and process. The intuitive touch screen interface allows for ease of use and flexibility. The machine software interface was developed to allow an unskilled operator to run many high precision machines simultaneously.

Simple Automation Integration

Simple Automation Integration

A variety of feeding systems are available. For feeding rods or balls, the feeder can be positioned from the top or side of the machine. We can also design semi-automated systems for testing and small production runs. Stainless-steel hoppers that can hold thousands of balls are also available. Custom solutions tailored to specialty applications are also available.

Remote Connectivity

Remote Connectivity

This machine can also interface with Glebar Advanced Analytics, our cloud-based solution that allows operators and managers to remotely receive actionable real-time analytics on easy-to-read dashboards. Decisions can be made using the data to reduce downtime. boost capacity, increase machine availability, and more.
