Breton Kappa M

Reasons why

  • 1
    Uniform reflectance on slab surface
  • 2
    Structural solidity for higher precision
  • 3
    Seamless continuous work table
  • 4
    Total safety
  • 5
    High energy efficiency and reduced operating costs
  • 6
    Working speed

The ideal solution for processing precious materials

“Low centre of mass” configuration for enhanced process sensitivity

The structure is designed to bring the spindle beam as close as possible to the work table to increase the effectiveness of spindle action on the slab surface by removing sources of anomalous vibration and possible tool to workpiece misalignments.

The honing-polishing units feature an anodised aluminium alloy structure designed to limit weight of the system while maximising its stiffness.

A double cylinder and independent pressure control for each head form the best solution for large production volumes and high quality standards.

Breton Kappa M is available in 3 versions to meet any production requirements.

Technological highlights

  • The 550 mm lap plate can be fitted with 9 abrasive tools. The vertical and tangential cushioning system assures ultra-sensitive processing without relinquishing access to the full power output when high surface pressure is needed, especially in coarse grains.

  • The load-bearing structure is made of arc-welded steel anchored to the foundations without any deformable connecting elements. The bed sub-structure is designed to prevent process water pooling, which could damage the frame.
