Piktogramm Außenbearbeitung Kegel

Technical data

Application external taper from Ø 1 mm
Standard fixture cylindrical shank or Morse taper
Tailor made fixture VDI, HSK etc.

Parameters

Workpiece allowance up to 0,01 mm
Spring deflection up to 4 mm
Lubrication Emulsion or oil; filtering the lubricant (< 40 µm) can improve the surface quality and service life of the tool.
Speed up to 50 m/min; speeds are calculated from the circumferential speed, based on the largest diameter
Feed rate 0.1–0.3 mm/U
Retention time 5–20 revolutions
Pre-machining of workpiece Surface roughness up to Rz 15 µm
Workpiece hardness 45 HRC

Tool for smoothening and strain hardening of external tapers. Internal springs generate the required rolling force. The value of the rolling force is defined by the preload of the tool. The spring characteristics can be adapted to the requirements of the workpiece.

ADVANTAGES

  • Short machining time
  • Both workpiece or tool can be driven
  • High productivity
  • Low investment costs
  • Simple replacement of wear parts
  • Compact dimensions
