This machine adopts microcomputer control system and human-machine interface, combined with ultra-high precision rotary encoder to locate and infrared device, uses inverter to control left-right feeding, adjusts the speed according to the stone material. It uses hydraulic lifting system, combination of chrome-plated guide pin and wear guide bush, with small gap, wearable, beautiful structure, and guide sleeve with multi-layer seals, with waterproof, dust-proof, anti-spill, improving the service life, main motor uses brand energy-efficient motor, reduces the later using cost; worktable use super heavy large size profiles welding together, larger than the table in the market, with more durable. Main parts adopt imported good-quality materials. Thus the whole machine is featured as high cutting efficiency, high cutting precision, high stability, easy–operating to suit specially cutting granite and marble with high value and big size.
