CNC Drilling Machine

DM4000-2

1. Uses

DM series machine is gantry movable type CNC drilling machine, mainly used for drilling tube plate, clapboard (including blind hole) in petrochemical machinery, air-cooled and heat-exchanger products etc. It adopts high-speed twist drill bit for low-speed drilling. Each of the power head can drill simultaneously or independently. It adopts CAD drawing and U-disk transfer. The process is convenient and intuitive. the realization of CAD/CAM, instead of artificial marking and template drilling, greatly improve production efficiency and work piece machining accuracy, shorten production preparation time, achieve semi-automatic production.
