Wheel bearing housing machining

Complex shapes are a challenge for the tool and machine

1. Pre-machining the wheel bearing bore

Roughing boring bar

  • Indexable inserts with TiB² coating for high cutting speeds and feeds
  • Diameter can be adjusted via short clamping holder for a consistent pre-machining dimension on the wheel bearing bore and therefore excellent process stability during finish machining
  • Quiet running during machining despite long overhang length, thanks to high balance quality

2. Finish machining the mounting surfaces and wheel bearing bore

PCD multi-purpose reamer

  • Multi-stage special-purpose tool with brazed PCD blanks
  • A single tool for milling over several surfaces and counterboring/intermediate machining
  • Excellent cycle time savings thanks to several tools combined in one
  • Quiet running during machining despite long overhang, thanks to high balance quality

3. Semi-machining of the wheel bearing bore including flat surface

PCD multi-purpose tool

  • Brazed and lasered PCD cutting edges guarantee micrometre-precise results
  • The combination of several diameters and contours in a single tool leads to excellent cycle time savings
  • High balance quality ensures quiet running during machining despite long overhang lengths
