Machine tool usage:
♦ Specialized in processing cylindrical deep hole workpieces
♦ Such as spindle holes for machining machine tools, various mechanical hydraulic cylinders, cylindrical through holes, blind holes, and stepped holes.
♦ Machine tools can not only undertake drilling and boring, but also perform rolling processing.
♦ Internal chip removal method is used during drilling.
♦ The machine tool bed has strong rigidity and good precision retention.
♦ The spindle speed range is wide, 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 and workpiece clamping are secured using hydraulic devices with instrument display, ensuring safety and reliability.
♦ This machine tool is a series of products and can also provide various deformation products according to customer needs.
