Product features
·The main large parts of the machine tool: the base, workbench, column, saddle and spindle box are all made of high-quality resin sand and high-strength high-quality cast iron, with a complete heat treatment process to eliminate residual stress, and sufficient reinforcing ribs are arranged to ensure that the whole machine has sufficient strength, rigidity and high stability;
·Taiwan's original heavy-duty linear guide rail is adopted, with strong rigidity and good dynamic accuracy;
·Three axis transmission adopts Taiwan grinding double nut ball screw, with compact structure, stable movement and high precision;
·The high rigidity Taiwan made spindle is lubricated with grease, and the spindle bearing can be used to obtain constant and reliable lubrication;
·The base adopts cast large water pan structure with good waterproof performance
