Multi-Part Grinding 
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.
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.
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.
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).
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.
Remote connectivity simplifies troubleshooting and maintenance.
Designed for feeding balls from a hopper assembly, channeling them into singular stations on the plunge grinder.
Includes dresser head assembly, Stylus checking system, slide assembly and platen which mounts on the back of the machine. This system enables the user to dress the grinding wheel while still mounted on the machine.
Collects and removes debri and dust from the work area.
Comes with arbor, flange with four weights and stand. Balanced grinding wheels are critical for high precision parts.
Post grinding and cleaning, the data is collected, analyzed and fed back to the machine for automatic size compensation. Measurements are shown on a trend graph on the machine control.
Built specific for the part; integrated into the cell.
Post grinding, system is integrated into the cell to pressure clean parts.
Both Z and X axis of feeder have velocity and position control set on the machine touch screen.
Automatically picks parts from trays, loads into machine, unloads and places back to parts tray. Fully guarded and interlocked access doors. Robot arm incorporates two grippers for staging the loading and unloading during the grind cycle, reducing idle time.
Available in manual and hydraulic version.

Glebar prides itself on selling precision grinding machine system solutions, tailored to your specific needs. Below is a small subset of applications, performed on this machine, that Glebar has provided solutions for over the years.
Current Process:
The balls are formed one at a time from bar stock on a lathe in multiple roughing and finishing tool paths. Molded balls are purchased from a contract manufacturer, then turned to achieve the desired diameter and to remove mold imperfections such as parting lines.
Challenges:
Purchasing the balls can be expensive, and long lead times create a need for increased inventory levels and consumption of cash. Turning can be slow and inconsistent, resulting in long cycle times, high scrap rates, and surface finishes that generally require downstream grinding or honing to meet specifications.
Current process:
Legacy equipment did not meet current CE standards. The brittle shafts break in the grinder's feeder increasing scrap rates.
Challenges:
Deliver an automated, turnkey process that can integrate with the customer's existing isostatic press to accuractely handle and grind the parts. The process had to ensure the ceramic shafts would not chip or break due to the brittle consistency of pre-sintered ceramics.
Challenge: To mass produce golf ball cores at a low cost, while holding tight tolerances with maximum throughput.
