Discriber-S

Over view

The Discriber-S™ is an automatic high-priction measurment system for Disc Thickness Variation(DTV) and Lateral Ron Out (LRO) of brake rotors. These conditions are the major causes of brake chatter/judder and can ultimately lead to premature NVH problems.

The system provides the user DTV and Runout data in a three-dimensional imaging format, thus helping in investigation and analysis of geometric structure deformation caused by over-heating and excessive mileage on the brake rotor.

 

Features

  • The sensors scan the full surface of friction part of the brake rotor with the selected track width automatically
  • A precision air bearing spindle supports the rotor while an air bearing slide holds the capacitance sensors to keep accurate measurement for long leasting performance.
  • A universal fixture is used to minimize the need for multiple fixtures and easily accommodates a wide variety of rotor shapes and sizes.
  • fixture accuracy check feature provides reliable measurement and maintenance.
