FDV-520A dual-spindle vertical machining center all-in-one machine [Dual-spindle + dual ATC, achieving high productivity!] Increase productivity by 2 times, reduce costs by 25%, and reduce floor space by 40% Reduce personnel expenses and factory operating costs The dual spindles Z/W are driven by independent servo motors, with independent structures and independent tool loading and unloading. The Z/W independent structure allows independent tool compensation without being limited by tool length. "Double spindle spacing fine adjustment (U-axis)" Fine adjustment of spindle spacing can significantly reduce fixture setup time U-axis ±1mm servo movement can perform: fixture assembly size deviation compensation, tool thermal compensation in the X-axis direction, and spindle thermal displacement compensation
