Outer Race Production – Efficient and Low-Cost

Outer races are difficult to machine with a traditional machining process. EMAG turning centers and ball track milling machines are customized to the specific processing task required to produce outer races, guaranteeing excellent results.

Precise Manufacturing of CV Joints – Focus on: Outer Races

The production of outer races is demanding on both the machine and the machining technology. Excellent quality for the ball tracks, tight tolerances in turning operations, and high volumes are required. To meet these demands, EMAG offers optimized manufacturing systems for the production of CV joint workpieces such as outer races, inner races and cages. These manufacturing processes are customized to each individual customer’s workpieces, which guarantees high productivity and availability.  

Outer Race Machining

The machines of the VSC series are designed for the highly productive manufacturing of outer races. By combining the turning and milling machining operations, the outer races are completely machined  in one clamping operation. The twin-spindle design ensures outstanding productivity.

Solutions for Outer Race Variants: 

  • Outer race processing – Fixed joint
  • Outer race processing – Sliding joint


  • Internal soft turning of outer races
  • Soft milling of ball tracks
  • Internal hard turning of outer races
  • Hard milling of ball tracks

Other Technologies Available from the EMAG Group

  • Induction hardening of outer races on EMAG eldec induction hardening machines including the VLC 100 IH series

Hardening of Outer Races – Fast, Controlled, Ideal for Line Integration

The VLC 100 IH is an induction hardening machine for the hardening of outer races that also utilizes the EMAG pick-up technique. The outer races are picked up automatically by the pick-up spindle with a center-drive chuck, and moved to the machining area for the hardening process, allowing the internal and external hardening of the outer races to be complete in just one clamping operation

Advantages Outer Race

  • The double-wall construction (gantry design) of the machine ensures outstanding stability. The machine base is created with thermally stable polymer concrete
  • Both soft and hard machining can be done with just one machine
  • Hard turning and hard milling in a single machine; full internal machining in one clamping operation = no clamping errors
  • Fully automatic production, easy machine integration into production systems
  • Customized design of the entire production system: both single-spindle and twin-spindle available
