Description and Features of TGG2115x4000mm Deep Hole Skraping Boring Machine

One Side Can Be 5mm Processing Margin

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, 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.

The machine body is manufactured with high-quality cast iron, with a high rigidity. The resin cement is used to irrigate the inside of machine body, with a very strong stability. The main shaft adopts a Beijing CTB 50KW ac servo drive, and the main shaft of boring bar box combines a 3-gear manual and servo drive for speed adjustment, with a wide scope of speed adjustment and a large torque. The feeding system adopts a Beijing CTB 9KW ac servo motor drive, and Φ80 ball screw transmission, with a steady feeding and a long service life, capable of meeting various deep-hole machining process requirements. The work-piece mounting adopts a hydraulic oil cylinder for tight propping, and combines tight clamping with hydraulic calipers, steady, reliable and convenient for loading/unloading. The electrical system adopts German Siemens 808 D CNC system for centralized control, capable of human-machine interaction and picture display, flexible to operate, safe and reliable.

In production it is suitable for mass production can also be suitable for small batch production. TGG2115x4000mm deep hole scraping boring machine is the best choice for producing hydraulic oil cylinder equipment.
