SPBO 2 Axes CNC Diamond Wire Saw Profiling, Blocks Dressing, Slab Cutting

The SPBO profiling machine of GRANI ROC is designed for a high precision dressing of blocks and slabbing and profiling production from stone blocks.
The machine is composed of a static structure and a mobile trolley. All the movements are controlled by a 2 axes CNC panel board.
· The movements of the machine are controlled by a 2 axes CNC. The data can be input directly in the CNC or by an ISO code file generated by the CAD-CAM software GraniCAD supplied with the machine. This software allows to design the pieces to be profiled, to transfer the *.dxf files to the CNC, to define the parameters of cutting in each step of the cut (speed of cutting, speed of the wire, etc.) and to simulate the path of the wire during the cut.
· Once the profiling file has been input in the machine board, the operator will have the possibility of modifying parameters such as cutting speed, wire speed with a full system of security on possible water shortage, wire broken, wire short or any kind of failure the machine may have
· The machine has an electric system for bringing closer the small guide wheels that allows the operator to adjust the cutting width until the one desired, reducing the arch value when cutting with diamond wire and thereby increasing its speed.
· The structure of the pillars and beam is made of electrowelded and machined tubes. The trolley is composed of electrowelded tubes forming a framework protecting all sensitive parts of the trolley like rod screws, wheels, etc.
· The tensioning of the wire is made pneumatic and automatically with indication of wire breakage or shortage. In this way the machine controls automatically the down movement of the machine, adapting it to the optimum working tension of the wire, avoiding possible breakages and optimizing its behaviour.
· All the main pulleys –drive and tensioning– and guiding wheels are protected by rubber liners in order to get the necessary traction of the wire. Such liners can be easily changed once they are worn out.
· The machine is equipped with an automatic cooling system for the diamond wire with detection of constant water pressure. This system stops the machine in the case of lack or insufficient water flow, protecting the tool and preventing possible deterioration or damage of the equipment.
· All the up and down screws are protected with hoods against dust and water
· The machines has an automatic greasing system that injects lubricating liquid in the critical parts of the machine ensuring their correct functioning and the long life of the spare parts.
