TGK2240 CNC Skiving roller burnishing machine
The TGK2240 CNC deep hole Skiving roller burnishing machine is mainly used for mass production of cylinder barrels. It is configured according to workpiece rotation tool rotation and is suitable for boring, scraping, and rolling operations. It can efficiently perform rough boring, as well as one-time boring, scraping, and rolling operations. The machining aperture accuracy is IT7-IT10 level, and the surface roughness is not greater than Ra0.2-0.4 μ m.
The TGK2240 CNC deep hole Skiving roller burnishing machine adopts a machining method of workpiece rotation and tool rotation feed. The spindle has a large bore structure, which can facilitate the discharge of iron chips and cutting fluid. The bed adopts double rectangular guide rails. The oil feeder moves through a servo motor and is positioned and pressed against the workpiece through a tapered hole. Adopting the hydraulic station in Yongzhen, Taiwan. The cooling system adopts an above ground oil tank structure, and the filtration method adopts a chip conveyor magnetic separator filtration method. The machine tool is equipped with a German SIEMENS CNC system, and the cylinder length is not more than 3m, using ball screw feed. For cylinder lengths greater than 3m, gear rack feed is used. The machine tool is equipped with high-efficiency automatic expansion and contraction combination cutting tools, and the machining efficiency is 3 to 5 times that of traditional deep hole machine tools.
