ATI’s line of Axially-Compliant (AC) Deburring Tools, also known as Speedeburr TM, are a patented family of robust, high-speed, low-weight air tools with a floating rotary cutting burr for edge-deburring and chamfering of aluminum, plastic, steel, etc. with a robot.  

While spinning at high speeds, a rotary cutting burr or file (tungsten carbide, PCD, or CBN coated cutting burr) rides on a cushion of air that provides compliance while maintaining a constant force. Because the rotary burr has a 45° cutting angle, the compliance is both lateral and axial. This patented force control system provides a very high stiffness in the path direction and a low stiffness in the contact force direction that prevents chattering (a common problem with robotic deburring). Due to the extremely low inertia of the cutting burr, Axially-Compliant Deburring Tools can quickly deburr parts, greatly reducing cycle time.

AC Deburring Tools maintain a consistent deburring result from part-to-part. The floating head design reacts quickly to any variances in part position or robot path. As a result, robot programming time can be reduced by up to 75%.

Features and Benefits  

• Designed for edge deburring and chamfering:
  AC Deburring Tools are uniquely and exclusively designed for edge deburring and chamfering.
  
  
• Reliable vane motor:
  Robust vane-type motor designed with rugged components provides long service with exceptional power.
  
  
• High-torque performance:
  Vane motors increase their torque in response to deburring demands.
  
  
• Floating axial compliance:
  Remotely set air pressure controls and maintains the constant axial force on the deburring cutter mounted in the Free Flying Piston (FFP). The axially compliant motion of the FFP allows the cutter to compensate for deviations in the part profile along the robot path.
  
  
• Mounting options:
  The AC Deburring Tools use adapter plates which are easily customized for robotic, bench, or fixture mounting.
  
  
• Simple file-change system:
  The cutting files mount to the unit using threaded shanks, and can be replaced easily and quickly without removing the tool from the robot.
  
  
• Easy teaching:
  The axial motion of the FFP and cutter allow fast and simple programming of the robot. The movement of the cutter compensates for changes in part tolerances, part misalignment, and robot path variation.
  
  
• Extensive industry use:
  AC Deburring Tools are being used by hundreds of customers throughout the world. Customers include Pratt & Whitney, Nissan, Volvo, Rolls Royce, Caterpillar, Saab, General Motors, John Deere, and many others.
