The die is servo driven, with intelligent torque protection, to overcome the traditional limitations of the lathe, drilling machine or manual tapping. Boasting advanced mechanical design, with a variety of processes using in-mold castings, the overall stiffness is strong, durable, non-deformable. The high definition touch screen is simple and intuitive. It can perform vertical and horizontal work of complex and heavy workpieces, locate quickly and process accurately. Continuous speed change, manual, automatic, with three different working modes. Auto mode can effectively control the touch depth, without the operation button, automatic control by depth controller. Fast repeated positioning, tapping speed, high production efficiency.
