Introducing the PG-9X20DHD

  • The PG-9x20DHD centerless grinder was designed to form ceramic components such as unfired carbide by Form grinding.
  • The traditional process of sizing carbide is to thrufeed the part in the hard state post-sintering. This method requires many passes and a large grinding machine in order to achieve the tight tolerances required for drills. Glebar solved this problem by shaping the carbide in the soft state to near net size.
  • With fragile components (consistency of chalk), care needs to be taken in handling the part while it is being ground – the PG-9X20DHD does this very well. The parts are then sintered and thru fed on a conventional grinder such as the GT-610. This unique process reduces throughput time, reduces the fallout rate and allows the ground carbide to be reclaimed and reused.
  • The machine has also been adapted to point quartz glass used to produce fiber optic cable.
With fragile components (consistency of chalk), care needs to be taken in handling the part while it is being ground – the PG-9X20DHD does this very well.

PG-9X20DHD Highlights

A Compact Carbide Rod Grinder

A Compact Carbide Rod Grinder

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, controlling slide velocity and position is done simply through touch screen control. 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.
