Automatic Edge Trimming Line for Slabs in Italy

MULTIBRETON TRIM - AUTOMATIC TRIMMING LINE FOR NATURAL STONE SLABS

Automatic trimming line for natural stone slabs This line is engineered to offer high-speed machining and to be incorporated into a polishing line and is designed to work at the same speed as the polishing machines. Both longitudinal and horizontal trimming operations are in a single run and ideal for slabs with a thickness up to 30 mm.

The horizontal trimmer consists of two cutting spindles which work in succession along the same cutting run resulting in a substantial increase in cutting speed. The two trimming systems are positioned in succession to one another, first the longitudinal and then the horizontal.

They work simultaneously guaranteeing high-speed operations which do not in any way condition or affect the speed of the polishing machine positioned downstream the line. The work cycle can be programmed and runs in automatic. The machines are fitted with a single control panel.

LONGITUDINAL TRIMMER

The MULTIBRETON TRIM L/2 mounts two spindles which remain in a fixed position and trim the slab as it is conveyed forwards on rollers. The spindles which travel along guides mounted to the cross-beam are positioned manually or as an optional accessory a motorised screw assembly can be fitted for spindle positioning operations. An easy to use handwheel is provided to lock and release the spindle.

As a further optional accessory a laser tracer system can be mounted allowing the operator to verify and trace cutting operations.

TRANSVERSAL TRIMMER

The MULTIBRETON TRIM /T/2 consists of a carriage which mounts two cutting discs. This carriage moves perpendicularly in respect to the slab being conveyed. A system of sensors relay information to the machine which stops the slab conveyor when the slab reaches the correct cutting position. Once each cutting operation is terminated, a pneumatic system raises the discs returning them to their original position and the slab is then conveyed forwards. The disc carriage moves along guides which are enclosed in a labyrinth protective housing. The waste shavings simply fall into a collection hopper mounted on free-moving rollers positioned underneath (optional accessory) and which is manually removed for emptying. Upon specific request this collection hopper can be replaced with a motorised conveyor system to convey the waste shavings to a larger collection hopper located outside of the workplace.

This head-cutting machine for slabs with width up to 2200 mm. optimizes the polishing work, eliminating any possible abrasive waste and useless points due to the natural asymmetry of the slab. The 1INT/L can be equipped with different optional accessories as the 4,5-meter long motorized roller conveyor, the vertical pneumatic pressures and the waste unloading container.

This machine performs the trimming and squaring operation on marble and granite slabs, through the elimination of both sides and ends irregularities. B713-B714 machine is mainly utilized in polishing and/or resining lines improving their performance through the preparation of consistently wide slabs with straight edges and without resin leakages. The waste cutting is performed through diamond discs which are moved to the selected position.
