CGV-900 Compliant Angle Grinder for Robots

June 23, 2023
ATI Industrial Automation's angle grinder creates an automated alternative for robotic grinding applications.

The CGV-900 Compliant Angle Grinder provides an automated alternative to grinding and finishing by hand for robotic grinding processes.

 

It offers built-in compliance, allowing the unit to compensate for irregularities in part surfaces and maintain contact with a workpiece. The compliance force is adjustable, enabling users to fine-tune their finishing processes in real time. It also provides position-sensing data to help indicate media wear to let users establish media replacement intervals, eliminating unexpected rework, and downtime. Additionally, the data can be used for process verification.

 

The grinder contains a governed, vane-style motor that provides a more consistent speed during the grinding and finishing processes. This ensures an even finish throughout the contact path of the tool. It's compatible with industry-standard grinding media such as flap wheels, sanding discs, and wire brushes.

  • Suited for grinding or finishing
  • Pneumatic vane motor
  • Built-in compliance reduces robot programming
  • Gravity compensation helps apply consistent force on the workpiece in any orientation
  • Cutting force is adjustable on the fly
  • Compliance travel position sensing monitors media wear and part differences
  • Mounts to robot arm via bolt up or bolt down pattern or 30-deg. mounting pattern
  • Can use flap wheels, sanding discs, and wire brushes
  • Minimal chattering and vibration
  • Replaces hand grinding

Applications:

  • Metal Fabrication
  • Automotive
  • Aerospace
  • General Industry
