introduction

PMD Series cnc drilling machine is a gantry mobile CNC high-speed drilling and milling machine. Carbide drills can be used for internal cooling high-speed drilling or The high-speed steel twist drill is used for external cold drilling. The processing process is numerically controlled, and theoperation  is very convenient.  It can  realize automation,  high  precision,  multiple varieties, and mass production.

Application

CNC drilling and tapping machine mainly used for drilling, tapping and milling of flanges, heat exchangers, tube sheet parts and slewing supports.also can be used in the of connecting plate in the steel structure such as building,bridge, tower and so on.

Features

Grey iron casting bed&worktable

The bed&worktable is made of high-qualitygray iron (HT300), with good rigidity andstrong stability. A number of transverseT-slots are arranged on the top to clampthe workpiece, (when installing, fix anumber of ground anchors to better fix thebed and improve the stability of themachine tool.)

Servo feed power head

T-type ram structure power head, the mainshaft motor adopts a special servo motor forthe main shaft to drive the main shaftthrough a synchronous belt, low speed andlarge torque, which can not only bear heavycutting load, but also suitable for high-speedmachining of cemented carbide tools
