​Rough boring

The CoroBore® XL system for large diameter rough boring provides rigid and reliable performance in larger bores and is designed to generate the required hole quality and diameter. The bridges and holders enable rough boring to be completed with high productivity.

Benefits

  • CoroBore® 111 four-edged standard inserts with optimized grade selection for rough boring applications
  • ​CoroTurn 107 and T-Max P inserts with dedicated grades and geometries for all materials
  • Reliable system with rigid interfaces between head and cartridge for stable and vibration-free boring
  • Large assortment of different cartridges available for a wide range of applications, such as the CoroBore XL cartridge specifically targeting rough boring in complex materials.
  • Also available as lightweight tools: CoroBore lightweight boring tools reduce tool weight and tool change moment, making handling easier and larger diameters possible
  • Also available as damped tool (Silent Tools) for vibration-free boring in diameter 148–300 mm (5.827–11.811 inch), even at long overhangs

​Fine boring

CoroBore® XL is the First Choice for large diameter fine boring. The tools can be adjusted radially in order to cover a certain diameter range with one tool. The tools allow precision adjustment in microns in order to achieve close hole tolerances.

Benefits

  • CoroTurn 107 and CoroTurn 111 inserts available with dedicated grades and geometries for all materials
  • Excellent surface finish with wiper inserts
  • Dedicated tool holders optimized for large diameter boring
  • Available as dampened tool (Silent Tools) for vibration-free boring in diameter 148–315 mm (5.827–12.402 inch), even at long overhangs
  • Also available as lightweight tools: CoroBore lightweight boring tools reduce tool weight and tool change moment, making handling easier and larger diameters possible

​Interpolation turning with CoroBore XL

Interpolation turning is a new, flexible turning method developed for advanced machining centers and B-axis multi-task machines. By using an innovative spindle option to synchronize tip position, the operation can be carried out by interpolating with the X- and Y-axis in a circular direction and rotating the machine spindle in time with the rotational contour.

Benefits

  • Flexible solution, making it possible to use machining centers with modular tool setups instead of dedicated boring machines with W-axis facing heads
  • The component can be machined completely without moving it—especially beneficial for large, non-symmetrical components
  • Reduced tool investment costs
