KUKA ready2_grind

Powered by 3M, the KUKA ready2_grind is a pre-configured robot system designed to reduce the uncertainty and time associated with automating weld grinding applications.

Have you considered automating your weld grinding operations?

3M and KUKA have collaborated to develop the ready2_grind system that allows customers to take the guesswork out of automating their weld removal process. The KUKA ready2_grind combines the precision performance of a KUKA KR 60 robot with 3M Abrasives and process expertise to provide a pre-configured system that delivers consistent grinding for the repeatable results customers need.
3M and KUKA have partnered to develop unique solutions for robot-based automation in the abrasives industry.

  • 3MTM Abrasives Starter Pack

    ready2_grind 3M Abrasives Starter Kit

    Robotic grinding relies on consistent, long-lasting abrasive performance to meet your finish requirements. These starter kits are designed for use on carbon or stainless steel. Available in 4.5 in. and 7 in. diameters.

    Carbon Steel Kits include:

    • 3M Cubitron II Fibre Disc 982C, grades 36+, 60+ and 80+ - for weld removal
    • Scoth-Brite Light Grinding and Blending Discs - Heavy Duty and Super Duty
    • Associated back-up pads and hubs


    Stainless Steel Kits include:

    • 3M Cubitron II 987C, grades 36+, 60+ and 80+ - for weld removal
    • Scotch-Brite Light Blending and Grinding Discs - Heavy Duty and Super Duty
    • Associated back-up pads and hubs
  • 3MTM Active Compliant Force Tool

    ready2_grind 3M Active Compliant Force Tool
    This component give the KUKA ready2_grind its "human touch." It attaches to the robot's arm and provides active compliance to allow the Servo Rotary Tool and abrasive to maintain contact with the workpiece surface at a specific force or pressure.
  • 3MTM Servo Rotary Tool

    ready2_grind 3M Servo Rotary Tool

    The 3M Servo Rotary Tool is the motor that spins the abrasive discs. It can be programmed to select and maintain speeds to optimize abrasive performance.

    • Features an automatic tool changer
    • Available with 3 or 5 horsepower, depending on the size of the 3M Abrasive discs you need for your application
  • Application Engineering Support

    ready2_grind engineering support

    Along with the robot and accessories, the ready2_grind system includes application engineering support:

    • Two days for 3M application engineer support developing a proof-of-concept trial for the customer's part at the 3M CAM Center
    • Connections with KUKA and 3M's extensive community of trained system integrators, each backed up on-call service from KUKA's global field service team
    • KUKA Call Center for first level support
