Grinding Stations Designed for Worm Gear Manufacture
Holroyd Precision’s WG grinding stations are designed to provide high levels of accuracy and finish in worm gear shaft production.

Friction Stir Welders Capable of Jointing Difficult Alloys
Precision Technologies Group (PTG) Heavy Industries will display its Powerstir friction stir welder.

Grinding Machine Accommodates Range of Abrasives
Holroyd’s Zenith 400 helical profile grinding machine has the capability to use three different grinding abrasives: vitrified aluminum or silicon oxide; “diamond hard,” plated CBN; and vitrified, dressable CBN.

Rotor Grinder Handles Helical Screw Components
The TG 350E rotor grinding machine from Precision Technologies Group’s Holroyd Machine Tools and Components division is designed to grind a variety of helical screw components.

Grinder Combines Three Technologies
The Zenith grinding machine uses three grinding technologies—aluminum oxide, "diamond-hard" plated cubic boron nitride (CBN) and vitrified CBN—to grind rotors as large as 420 mm.

Precisely Grind Helical/Spur Gears
The Holroyd gear and thread grinder, GTG2, is designed for precision grinding of helical/spur gears in diameters ranging to 350 mm. According to the company, the machine can grind small batches of these gears to high levels of DIN and AGMA quality standards.
