In production it is suitable for mass production can also be suitable for small batch production.

TG2115x4000mm deep hole skraping boring machine is equipped with large capacity automatic chip removal machine, drum magnetic separator, collect automatically iron into attle box, cooling fluid can be recycled by precision filtration.

TGG2115x4000mm deep hole scraping boring machine has a big ration power, a high rigidity, a wide allowance of machining process, and a very high machining efficiency, as ideal equipment suitable for machining various cylindrical deep-hole work pieces, capable of machining various mechanic hydraulic oil cylinders, the through-holes and stepped holes, etc. of cylindrical work pieces, etc. The machine is mainly used for bore and roll machining. The machine adopts the fine-scraping and rolling integrated machining process based on the rotation of boring tool. Front-row scraping is adopted for boring. The boring way is push boring, oil feeding by oil feeder at the center of boring bar and headstock chip removal. Rolling is post-tensioning rolling. Korean SRB high-speed scraping/boring rolling head is applied. The application of this machine will bring an epoch-making revolution to the production process of oil cylinder. The cylindricity and the concentricity of machining work piece are very high. The cutting and rolling speed of producing oil cylinder with cold drawn pipe can reach 1.2 meters/min.
