The ram-type power head with vertical CNC feed, its vertical slide table and power head ram are all cast with high-quality gray iron (HT300). Four-rail arrangement is adopted. The force is more stable. The spindle motor of the power head adopts a dedicated servo motor for the spindle to drive the spindle through a synchronous belt, with large torque at low speed, which can not only bear heavy cutting load, but also be suitable for high-speed machining of cemented carbide tools. All-in-one drilling, tapping and milling. Equipped with a spindle torque detection sensor, by setting the cutting torque value, the equipment can automatically stop drilling when the tool is severely worn or chipped, preventing further drilling and preventing the appearance of unqualified holes.
