Tk2125 Deep Hole Drilling Machine

The machine is specialized in machining cylindrical deep-hole workpieces, such as spindle holes for machine tools, various mechanical hydraulic cylinders, cylindrical through-holes for cylinders, blind holes and stepped holes 0. 4I m. The processing aperture accuracy can be up to IT7 ~ IT8 or above, the surface roughness can reach Ra0. 4I m. The machine tool can not only undertake drilling and boring, but also can perform rolling processing, and the internal chip removal method is used for drilling. The machine bed is rigid and has excellent precision. The spindle has a wide range of speeds, and the feed system is driven by an AC servo motor, which can adapt to the needs of various deep hole machining processes. The oil feeder is fastened and the workpiece is tightly clamped with a hydraulic device. The instrument display is safe and reliable. The machine is a series of products, and can also provide a variety of deformation products according to user needs.
