This 2+2 Type CNC Pipe Straightening and Cutting Machine serves as an efficient automated processing solution for metal tubular workpieces, integrating multiple core production procedures into one compact unit. Equipped with precision numerical control configuration, the equipment covers uncoiling, straightening and fixed-length chipless cutting in a single continuous workflow, eliminating intermediate handling between separate devices. As a mature Integrated Tube Processing Machine, it abandons traditional chip-generating cutting modes to deliver smooth burr-free pipe end surfaces and stable finished dimensional accuracy.
Built with refined calibration structures derived from mature Pipe Straightener design concepts, the unit effectively corrects bending deformation generated during raw pipe coiling, ensuring consistent straightness before cutting. Widely matched with copper and aluminium pipes for air conditioning and water heater manufacturing, it simplifies workshop layout, lowers labor input and material waste, becoming a preferred automated machining option for mid-to-large pipe processing manufacturers.
