Multibreton TRIM - Automatic trimming line for granite 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.

Discharge and stone shaving crusher (optional accessory) 
This system consists of two rotating rams which crush the stone shavings, the waste material is collected in a collection hopper mounted on free-moving rollers which is then removed manually 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. 

Dual disc horizontal 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.

Programming of the trimming line
Programming and control of the trimming line are simple and user-friendly.The cutting spindles of the longitudinal trimmer are aligned manually according to the width of the pack of slabs to be trimmed. As an optional accessory two laser systems can be mounted over each spindle to facilitate positioning.
The slab moves under the two cutting spindles, is trimmed longitudinally and then advances at a high speed towards the horizontal trimmer. A system of contact limit-switches guarantees the correct positioning of the slab under the cutting spindles of the horizontal trimmer for processing both the leading and trailing edge of the slab.
If needed, the operator can reposition the slab under the spindles of the horizontal trimmer using the gearshift of the conveyor where the slab rests. When positioning is completed, the operator presses the “START” button to start cutting.

The TRIM machine in the polishing line
The TRIM machine is usually incorporated into the polishing line just before the polisher: this results in a double saving in abrasive stones and polishing time since slabs already squared are polished.
The trimming machines can cut granite slabs as thick as 5 cm and up to 3 cm thickness the trimming speed does not affect the polishing speed.
