Structural features of the CNC Milling Machine
High rigidity and long-term precision retention
1, cnc vertical machining center main large parts: base, boat seat, slide seat, cow head, ram are made of high quality resin Sand molding, high-strength high-quality cast iron, complete heat treatment process to eliminate residual stress, and arrange enough reinforcing ribs to ensure sufficient strength, rigidity and high stability of the machine;
2. The B and C axes adopt the Italian imported turntable. The turntable has high precision, good repeat positioning accuracy, adjustable worm and worm clearance, and convenient maintenance.
3, the three-axis adopts roller linear guide, which has strong rigidity and good dynamic precision;
4. The three-axis transmission adopts Taiwan brand grinding double nut ball screw, which has compact structure, stable movement and high precision. The screw support is supported by a precision screw rod, pre-stretched at both ends, eliminating the loss of precision caused by thermal elongation, and forming a stable high-rigidity mechanical transmission system;
5. The base adopts a large water tray structure for casting, which has good waterproof performance;
6, high rigidity Taiwan brand BT40 spindle, lubricated with grease, can make the spindle bearing Constant and reliable lubrication, both economical and environmentally friendly, and long-term maintenance-free;
