◆The main large parts of the machine tool: the base, saddle, worktable, column, and headstock are all made of high-quality resin sand molding, high-strength high-quality cast iron, with a complete heat treatment process to eliminate residual stress, and sufficient reinforcement plates are arranged to ensure The whole machine has sufficient strength, rigidity and high stability ◆The XY axis adopts roller linear guide, which has strong rigidity and good dynamic accuracy; ◆The three-axis transmission adopts Taiwan-made ground double-nut ball screw, which is compact in structure, stable in movement and high in precision. The screw support adopts the original imported screw support bearing made in Japan, and the two ends are pre-stretched to eliminate the loss of precision caused by thermal elongation. Form a stable and high-rigidity mechanical transmission system; ◆The base adopts a casting large water tray structure, which has good waterproof performance; ◆The high-rigidity Taiwan-made BT50 spindle is lubricated with grease, which can make the spindle bearings get constant and reliable lubrication, which is economical and environmentally friendly and realizes long-term maintenance-free;
