TG2125x6000mm Deep Hole Skraping Rolling Machine

TG2125x6000mm Deep Hole Scraping Rolling Machines we offer are applicative for machining cylindrical through-holes, cylindrical deep-hole work-pieces, different kinds of mechanic hydraulic oil cylinders, stepped holes and blind-holes. The machines are mainly utilized for bore and roll machining and adopt the boring method of stiff work-piece and rotating boring instruments.

In every every 8 minutes, one ∮80 oil cylinder can be made with a length of 6000mm.

The frames of the machines are fabricated with high-quality cast iron that bestows rigidity. The primary shaft adopts a 30KW ac servo drive, with a broad scope of momentum and speed adjustments as well as large torques. The feeding system selects 5.5KW ac servo motor drives, which are capable of catering assorted deep-hole machining technical needs. The fastening or sealing work-piece of oil feeder selects a hydraulic instrumentation for tight propping. The electrical system of the products takes Taiwan Delta PLC centralized control and TFT (Thin Film Transistor) color touch screen LCD display that is flexible to control with safe and reliable procedures. These can manage large-batch production as well as small-batch single-piece production, efficiently.
