ZK21F series machine Introduction: ZK21F series model machines, efficient, high-precision, highly automated CNC machine tools Deep hole drilling two-dimensional coordinate system. X (table traverse), Y (table movements), Z (drill feed) are three-axis AC servo CNC control. The process can be easily shaped body type, box type and shaft parts. Hydraulic systems placed in parallel with the host machine, the overall structure is compact, easy to operate. With automatic chip removal, filtration devices (magnetic, tape, network type, magnetic filtration) and the oil cooler, filtration precision up to 20um.
