CNC High Speed Plate Drilling Machine Model PMZ2520H

CNC high speed drilling machine for plate tubesheet flange model PMZ2520H is mainly used for the drilling processing for steel, stainless steel and composite material. It is mainly used for drilling (including blind holes) process of the tube plate, baffle plate in petrochemical machinery, air condenser, heat exchanger etc. and large flange manufacturing, and also for joint plates in building, bridge, iron tower, etc.

It is mainly used for high-efficiency drilling processing of flanges, discs, ring types, tube sheet parts, and can realize the functions of drilling through holes, drilling blind holes, and step holes on simple materials and composite materials. It adopts cemented carbide drills. Cold high-speed drilling or external cold drilling with high-speed steel twist drills. The machining process of the machine tool is digitally controlled and the operation is very convenient. It can realize automation, high precision, multi-variety and mass production. It can be used for drilling through holes as well as blind holes. The accuracy of the processed components meets the national standard "Code for Construction Quality Acceptance of Steel Structures" (No. GB50205-2001).
