Using a PG-9BHD, the part is ground centerlessly -- the action of the work and regulating wheels contain and rotate the part without the need to hold the ends. For example, drumsticks have been traditionally made with a back-knife lathe, that rotates a wooden dowel by holding it the ends. This inefficient process leaves extra material at the ends, which must be cut off, requiring the stick to be polished using additional pieces of equipment. With the Glebar PG-9BHD Form Grinder, the drumstick is made in less time, in fewer operations, and is dimensionally more accurate. The highest quality drumsticks in the world are made using Glebar equipment.
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-9BHD 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. A hard chrome plated regulating wheel slide is dovetail ground for longevity, yet smooth due to our use of Turcite for gibs.
The machine is designed for contour dressing directly on the machine. Straight-line or template-tracing hydraulic dressers are also used in certain applications. Glebar also produces offline dressing machines: the manual DM-9B and the fully-automated DM-9CNC.
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.
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.
Uses a formed template to dress shallow shapes into the grinding wheel. An auto dress version of this dresser available.
Uses a formed template to dress shallow shapes into the regulating wheel.
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.
Both Z and X axis of feeder have velocity and position control set on the machine touch screen.
Available in manual and hydraulic version.
30 gallon capacity with two removable settling tanks centrifugal pump & filtration package
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.
Manufacturers use lapping machines which are unable to hold consistent tolerances or capacity, creating inconsistent surface finishes and longer cycle times.
Provide a form grinding solution for 1" and 1.4" deodorant balls while meeting the customer's cycle time and surface finish requirements.
