VX-1210 Hard Stone Diamond Wire Saw Mohs 7.0 PLC Control 138kW for Granite Quartzite Basalt Processing

VX-1210 Heavy-Duty Diamond Wire Saw - Built for the Hardest Stone

The VX-1210-HD is purpose-engineered for the most demanding stone processing applications: cutting granite, quartzite, basalt, and engineered stone with hardness ratings up to Mohs 7.0. Where standard wire saws struggle with excessive wire consumption, reduced cutting speeds, and premature component wear on these abrasive materials, the VX-1210-HD's heavy-duty construction and intelligent control system maintain consistent performance and profitability.

Key to its hard stone capability is the adaptive load-sensing feed control system. The Siemens PLC continuously monitors main motor current draw as a proxy for cutting resistance, automatically adjusting feed rate to maintain optimal cutting pressure. When the wire encounters a particularly dense quartz vein or abrasive inclusion, the system momentarily reduces feed speed to prevent overloading—then accelerates back to maximum rate once the obstacle is cleared. This dynamic response prevents both wire breakage and the "dwell marks" that occur when feed speed fluctuates erratically.

For hard stone, we recommend 0.55mm-0.65mm diamond wire with enhanced diamond concentration. The slightly thicker wire provides the durability needed for continuous granite and quartzite cutting while still delivering 50% less kerf loss than conventional 1.2mm wire. The machine's heavy-duty flywheel bearings, reinforced guide rollers with tungsten carbide contact surfaces, and oversized cooling system are all specified for the higher thermal and mechanical loads generated during hard stone processing.
