GEAR CUTTING & BROACHING
Xtrac has an extensive range of CNC machinery producing both involute and free form profiles and subject to peripheral considerations we are able to achieve parallel, tapered and non-orthogonal gear systems. Although traditionally, racing transmissions are spur gears, Xtrac has a philosophy and capability to manufacture all forms of spur and helical tooth profiles suitable for the most arduous racing application and the most demanding NVH properties required for today’s luxury saloon and electric vehicles.

Hobbed gear forms up to 300mm in diameter and up to 400mm lead.
Shaped gear forms from 4mm to 400mm and up to 120mm in lead.
Vertical broaching to form internal splines and gears.
Ground spur and helical gears both external and internal according to the Kapp method, by form grinding using ceramic and CBN wheels, up to 500mm in diameter.
Straight cut bevels to the Gleason Coniflex© System.
CNC chamfering for tooth clipping, rounding and free form leads.
EDM (Electrical discharge machining) is also used to form gear and spline profiles from the master CAD data.
Gearcutting Ratio Manufacturing Cell
Xtrac operates dedicated manufacture cells to achieve World Class Manufacturing Techniques, for Gear Ratios and Engine Timing Gears. The concept of the cell is to dedicate a complete facility that combines all of the manufacturing machinery, measurement equipment, knowledge and people, necessary to achieve a reliable, efficient and consistent product. Set up to minimise travel between machines, the cell improves part visibility and thereby planning to reduce manufacturing lead-times and continuous improvement to on-time delivery.
At the heart of the cell is a Cell Manager who is responsible for his team and his CNC machinery. Including Okuma twin spindle lathes, Matsuura hard machining mills, Pfauter hobbers, a vertical broach, a laser etcher, Studer grinders and a centralised inspection facility.
The use of quality improvement teams driven by Key Performance Indicators, provides continuous improvement where our multi-skilled operators are proud of their achievements and leading role to the Company.
