WG Series worm gear grinding stations

WG Series worm gear grinding stations offer ultra-high levels of accuracy and finish in worm gear shaft manufacture to AGMA 14/DIN2.

Depending on the model chosen, users can precision grind worm shafts in sizes ranging from 3mm to 500mm diameter and thread lengths up to 1600mm. A 130mm diameter through bore work head accommodates long shaft lengths.

Designed and built in the UK, WG machines combine high power for deep grinding operations with fast set up time to maximise production and minimise operating costs.

Every WG machine also benefits from a purpose-designed control system incorporating a menu-driven user interface. This capability makes it simple and straightforward for operators to input data from gear drawings, to produce profile and grinding paths and to generate standard tooth forms or perform topological modifications to tooth profiles.
