A compact form grinding machine that challenges the conventional process of making drill blanks and extends the capability of Form grinding to 20” wide.
Built on the compact base of the PG-9DHD machine, an extended 20” (508 mm) work wheel and regulating wheel allows several components to be ground simultaneously. Using a rigid hard chromed slide assembly with a resolution of 0.1 micron, the PG-9X20DHD will Form grind a 20” long 0.5” diameter green tungsten carbide rod down to 0.250” in less than 12 seconds to 0.001” (25 µm) accuracy.
Controlling slide velocity and position is done simply through touchscreen HMI control. Glebar develops the software in-house, designed specifically for your application.
Remote connectivity simplifies troubleshooting and maintenance.
Built specific for the part, the gantry picks and places parts in the grind zone in one motion.
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.
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.

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.
A top tier technical glass OEM required a precision grinding solution for quartz glass rod components which will be transformed into fiber optic cable cores. They needed to improve their existing process to increase output while maintaining a small footprint in their factory. Precision is paramount as the glass will ultimately need to transmit light over long distances without any boosting and without losing any of the information that has been encoded onto that light.
To establish a process whereby pre-sintered carbide drill blanks processed in a hot isostatic press (HIP) can be pre-sized to produce straight rod stock for long blanks. The existing method of manufacture involves sintering the carbide rods in a hot isostatic press then grinding them to size in a hard state before the fluting operation is performed. This procedure requires multiple thrufeed grinding operations which is labor intensive and accelerates wear and tear to the grinding machine and tooling since the hard carbide usually has a non-uniform lumpy surface; furthermore several thrufeed passes are need post-sintering to size the carbide to its final diameter and to achieve the uniform diameter required.
