It must be frank. Frank's numerical control system is very good, and its "five-axis linkage numerical control system" is the world leader. Choosing CNC equipment depends on "hardware" and "software". Hardware is the precision of machine tool manufacturing, and there is little difference between countries and factories. The gap is mainly the part of CNC system as "software", which is also the "soft rib" of CNC equipment produced in many countries, and the gap of equipment is also reflected in CNC system.
