Send InquiryThe machine is equipped with large power, strong rigidity, wide margin of machining process and extremely high machining efficiency, is the ideal equipment for all kinds of cylindrical workpieces with deep holes. This machine can process a variety of mechanical hydraulic oil cylinder, cylindrical workpiece holes and ladder holes, etc. The machine is mainly used for boring and rolling processing, machine tool adopting the precision boring cutter rotating scrape, rolling processing technology. Remove chips in front when boring and scraping and the boring way is to push boring, granted by the oil tank in central of boring bar, remove chips on the head of a bed. The rolling is the post-tensioning, applies the high-speed scraping and boring rolling head, can processing efficiently the oil cylinder, reversing the traditional process of a rough boring, glossy boring, grinding cylinder, the production efficiency is the traditional process of 5 to 10 times.
Application of this machine will have an epoch-making revolution for the oil cylinder production. Cylindricity and alignment of processing workpieces is very high, cutting and rolling speed can reach 1 m/min with the cylinder produced by cold drawn pipe, cutting and rolling speed can reach 0.3 m/min with the cylinder produced by hot rolled pipe. Finish the molding at the first time.
