Drake now offers powertrain and steering manufacturers four types of machines for producing steering and gear box components: gear grinders for finish grinding pre-cut gears in one setup with fast changeover; worm grinders for producing steering worms and other complex geometries needing up to 90 deg power helix; gear hobbers for roughing with auto load and probing; and rack mills that can mill steering racks in 35 sec to a 0.4 Ra cut tooth finish with magazine load and unload.
