The 560 mm diameter lap plate allows the use of 10 abrasive tools and ensures the highest material removal capacity and stability for perfect, uniform polishing. 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.
Moving bridge slab polishing machine
High productivity slab polishing machine for calcareous materials
The honing-polishing units are in aluminium alloy to limit weight and maximise stiffness.

- Uniform reflectance on slab surface1
Uniform reflectance on slab surface
The two brushless motors assure constant torque, both in maximum speed traverse movements and in reduced speed movements during slab edge direction changes. The brushless motors mean deceleration and acceleration ramps are perfectly controlled.
- Structurally robust for durable high precision2
Structurally robust for durable high precision
The structure was designed to bring the spindle beam as close as possible to the work table thus eliminating the need for extensions on the lap plates to reach the slab.
The honing-polishing units feature an anodised aluminium alloy structure designed to limit weight of the system while maximising its stiffness.
The lift/lower mechanism is balanced by a pair of cylinders with protected internal rods. Each head is equipped with a pressure regulator.
- Belt sliding surface in steel3
Belt sliding surface in steel
The belt sliding surface is made of steel with the option of adding an interchangeable table with rolled steel sheets as an accessory. The sheets are fastened to the underlying table with screws to allow rapid replacement when necessary. This accessory is recommended to preserve the good condition and flatness of the steel table in time.
- Total safety4
The front sliding safety/sound absorbing panels are composed of an ABS sandwich structure.
- High energy efficiency and reduced operating costs5
High energy efficiency and reduced operating costs
The design goal is to maximise ROI considering the entire life cycle of the machine and the maintenance costs linked to the technical solutions adopted.
Breton Kappa MM allows in line regeneration of braking energy. The system constantly checks abrasive wear on each head and sends a warning signal before the tool is completely consumed.
- Working speed6
The system also guarantees minimal lifting of the heads on slab infeed and outfeed, and subsequent rapid head descent, thus ensuring better polishing of the edges and a higher operating speed.
Excellence in the polishing process
Low centre of mass structure, powerful spindle drives and generously sized transmission, bridge drive with brushless for high dynamic swing movements. All this and far more besides makes Kappa MM the ideal solution for companies seeking high productivity when working with difficult and precious calcareous materials.
The exclusive and patented Tango solution is particularly suitable for reducing dull areas both on polished and honed material, making an appreciable contribution to raising line speed.

- / 0110 position lap plate
This Breton patented system completely eliminates the problem of opacity along the slab borders. The system generates an oscillatory movement of the spindles group and when combined with the beam movement it creates sinusoidal working trajectories developed specifically for each material type. Tango technology gives top quality uniform finishes over the entire surface of the slab, in both polishing and honing./ 02Tango orbital system to eliminate areas of opacity
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./ 03Load-bearing structure in arc welded steel
The splash barrier protects against the egress of material, keeping the work area clean and safe. The barrier is fully automatic: it adjusts its height according to the thickness of the slab being processed and rises once the process is finished./ 04Splash protection barriers with automatic adjustment
The manual centralised lubrication system with pump and lube cycle selected from a single position is composed of a grease reservoir, a pump with a fine mesh double strainer system, progressive dividers and tubing; the automatic pump can be added as an accessory./ 05Centralised lubrication
Each spindle is fitted with a protective front plastic housing that can easily be removed, making servicing the spindle body a simple task./ 06Easy spindle body access for maintenance
The kinetic energy recovered in spindle beam braking phases is injected into the power grid to maximise economy of the process./ 07Braking energy recovery system
