In the construction industry, the high-speed intelligent metal circular saw machine is also an essential tool. A large amount of metal products such as steel and aluminum alloys are used in construction, and these materials often need to be cut and connected according to construction requirements. This device can accurately cut metal materials and ensure that the cutting surface is flat and smooth. Like the tower crane connecting sleeve, after precise sawing, the two end faces can save materials without processing, and automatic production lines can be achieved through sawing, chamfering, punching.
