APPLICATION
The machine is mainly used for drilling tubesheets. Internal cooling high-speed drilling with carbide milling cutters or external cooling drilling with ordinary high-speed steel twist drills, end mills can also be used to mill grooves and special tools are used to mill the expansion grooves of the tube holes of the tubesheet. The machining process of the machine is digitally controlled. The operation is very convenient. It can realize automation, high precision, multi-variety and mass production.
