The host machine uses a base plus a four-column guide rail screw lifting beam structure, and a self-created table with high-precision chrome multi-roller support. The traditional sliding friction mode between the workpiece carrier (transmission belt) and the support table is perfectly switched to a rolling friction mode, which effectively solves the processing of self-heavy workpieces; the enlarged (strong) front and rear drive wave wheels rotate smoothly and lightly, effectively reducing slip and high transmission accuracy; the inner and outer surfaces of the whole machine are treated with high-performance anti-corrosion and anti-rust treatment, which effectively extends the life of the whole machine and has a high value retention rate. The machine has a large processing range, low processing noise, and realizes dust-free cutting. It is a new type of environmentally friendly equipment with multiple uses and distinct advantages.
