High Speed CNC Plate Drilling Machine

The machine is a gantry moving CNC drilling machine, which is mainly used for high-efficiency drilling of flanges, discs, ring types, and tube sheet parts. It can drill through holes, drill blind holes, and step holes on simple materials and composite materials. And other functions, using hard alloy drill bit internal cooling high-speed drilling or high-speed steel twist drill external cooling drilling. The machining process of the machine tool is digitally controlled and the operation is very convenient. It can realize automation, high precision, multiple varieties and mass production.
