Introducing the PG-9DHD

  • The PG-9DHD Centerless Form Grinder is an adaptation of the Glebar workhorse, the PG-9BHD. Similar in basic functional configuration as the BHD machine, the DHD is a high precision version.
  • With its 10” wheel, this Form grinder is capable of multiple-part-per cycle grinding, also offering slide positions and controllability not achievable for the more basic PLC driven unit.
  • Glebar’s unique Form grinding process can shape any spherical or cylindrical component into unlimited forms on a large variety of materials. This highly productive method of manufacturing surpasses competing methods where cutting tools or back knifes are used. When automated, this machine’s productivity and performance is nearly impossible to surpass. 
  • Chances are, that in every household, you will find a component that was ground on a Glebar Form Grinder. Example grinding applications range from basic deodorant balls, golf balls and pen nibs to drumsticks, check valves and fuses.
Glebar has over 60 years of Form grinding experience – having introduced the first compact Form grinder to the market in 1952, our history is firmly rooted in this type of grinding.

PG-9DHD Highlights

10” Wide Work Wheel for Multiple Part Per Cycle Capability

10” Wide Work Wheel for Multiple Part Per Cycle Capability

Since this machine accepts a 10" wide grinding wheel, multiple parts per cycle can be generated in a single infeed motion and with our vast knowledge base of material matching, we can marry the optimum grinding wheel to handle almost any material – from foam to diamonds.

Powerful 15HP Motor and Rigid Spindle for Heavy Grinding

Powerful 15HP Motor and Rigid Spindle for Heavy Grinding

The PG-9DHD can be fitted with a 15HP main spindle motor for heavy grinding of materials such as G10 fiberglass turning cylinders into balls. The spindle is a high precision twin grip setup with cartridge bearings. A stepper driven hard chrome plated regulating wheel slide is dovetail ground for longevity, yet smooth due to our use of Turcite for gibs.

Work Wheel Dressing Options

Work Wheel Dressing Options

To shape the grinding wheel, the machine has the ability to become a work wheel dresser allowing the operator to manually dress the grinding wheel on the machine. Also, if you wish to automate this process, we offer two other options. The DM-9B Dresser (offline system used to dress the grinding wheel), or the more advanced DM-9CNC (a CNC programmable wheel dressing machine that can be operated using our simple touch screen control).

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. 

Remote Connectivity

Remote connectivity simplifies troubleshooting and maintenance.

Automation and Accessories

Automation and Accessories

A variety of feeding systems are available for rod or ball feeding from the top or side of the machine, from semi-automated systems for testing and small production runs all the way up to stainless-steel hoppers that can hold thousands of balls. Custom solutions tailored to specialty applications are also available.
