Flange for Double Row Taper Bearing

Descripción

A roller bearing manufacturer in South Korea wanted to implement the most cost efficient method to drill and deburr holes into a bearing flange into their new development. 

Application details

Application details

  • Drilling: 9 holes Ø8.8 mm
  • Drilling: 2 holes Ø7.1 mm
  • Workpiece thickness: 6.0 mm
  • Chamfering: front and back
  • Machine: DMG MORI Tapping Center

Proposed solution

Proposed solution

HEULE proposed two VEX-S combination drilling tools, for each diameter one. The combination of drilling and chamfering at the front and the back of the bore reduces the three different operation steps to a single on.

Machining parameters:

  • Drilling Ø8.8 mm & Ø7.1 mm:
    Working speed: 88 m/min
    Working feed: 0.25 mm/rev.
  • Front and Back chamfer
    Working speed: 88 m/min.
    Working feed: 0.2 mm/rev.
  • Cycle Time for both operations: 3 sec.
