Gang hobbing gears Gear milling a pinion

DJC Gears

Our facilities include hobbing, milling and cnc milling of gears and worms especially very small ones up to 2 inches or 50mmm diameter.

We can make the awkward small gears others turn away.

We have developed our own 5 axis CNC machine to mill specials.
