Global Rotator Infinity Creates Bevel Cuts for the TMC4500ST

The Global Rotator Infinity continuous rotation is capable of accurately cutting bevel profiles (non-vertical) on nearly any contour. When the machine is programmed to cut at a bevel angle, the current and stand-off height is controlled by the same NC part program on the Global Control Plus.

The system is used to create bevels for weld-preparation surfaces or for active edges as used on earth engagement tools. Bevel and Land edge configurations can be created via multiple passes. The Global Rotator Infinity is available on the TMC4500ST machine.

The bevel angle is automatically set using a combination of A-axis and C-axis interpolation by the CNC. The C-axis may be programmed as a positioning axis or a coordinated motion in conjunction with the X/Y linear axis. When operated along with X/Y motion, the C-axis will maintain the bevel position tangent to the direction of travel.

Key Features

  • AC drives for high performance.
     
  • Programmable arc current, arc voltage, and bevel angle.
     
  • Infinite C-axis rotation at a rate of 75 RPM, reduces cut cycle and programming time.
     
  • Quick torch focal point adjustment for easy consumable changeover.
     
  • Lateral and vertical torch "decoupler" collision detection to prevent torch damage in event of a collision.
     
  • Automatic torch height control by analog arc voltage with an accuracy of +/- .006 inches so part accuracy is maintained during bevel cutting.
     
  • Resultant piece part bevel angles of +45 degrees through -45 degrees.
