TG2115x4000mm Deep Hole Skraping Boring Machine

The base of TG2115x4000mm Deep Hole Skraping Boring Machines are factory-made with advanced quality cast iron. Endowed with stiff rigidity and stability. Boring bar box spindles are operated by ac servo motor with wide speed range, large production torques and feed system. AC servo motors are driven by double rack transmittance, fast feeding, extended service life and can conform to the requirements of all types of deep hole machining activity. The workpiece loading card espouses tight hydraulic cylinder that is stable and reliable with effortless management. The electrical system follows centralized control CNC system, which can be interdependent. Endowed with graphical displays the products have flexible operation and are demanded for their reliability. In production these are suited to mass production and are also appropriate for small batch production.

Korean SRB advanced-speed scraping/boring rolling head is exerted. The utilization of these machines will bring forward an epoch-making revolution to the production activity of oil cylinder. The concentricity and cylindricity these machines work piece are really high. The rolling and cutting speed of making oil cylinder with cold drawn pipe can range to 1.2 meters/min.
