TS27R contact tool setting probe



This text will be replaced

TS27R is mounted on the machine table. It enables the user to set tool length and diameter of rotating tools, and to carry out broken tool detection.

As with all Renishaw hard-wired probe systems, TS27R requires the MI 8 interface or HSI to convert probe signals into an acceptable form for the CNC machine control.

TS27R features and benefits

  • The standard tool setting probe for machining centres
  • Compact table mounting
  • Precise tool length and diameter measurement
  • Rotating tools can be checked without wear to the tool or stylus
  • Stylus is protected by a weak link, preventing probe damage in the event of a collision
