SK6220CNC thread milling machine
Main performance and purpose of the equipment：
This machine tool is a specialized machine tool that uses comb shaped thread milling cutters to process short internal and external threads. It has better performance in processing small and medium-sized blind hole threads, and the workpiece can be clamped with a top dial, three jaw chuck, or hydraulic spring chuck. The tailstock can be used to process short external threads on slender shaft workpieces. The machine tool is made in JapanFANUCProduced by the company0i-MANumerical control system, three-axis two linkage. The feed system adoptsFANUCThe company's communication servo motor directly drives high-precision ball screw pairs or high-precision worm pairs. The milling cutter spindle is driven by an AC variable frequency continuously variable speed motor, and the variable frequency motor works within a constant power range through the gearbox variable speed, thus achieving efficient milling.
This machine tool is mainly suitable for large-scale or mass-produced industries such as automobiles, tractors, and defense industry
