Fully automatic electric pipe cutting machine designed for quick and efficient cutting of pipes ranging from 15-400 mm in diameter. The ZD220 model is ideal for pipes up to 220mm, handling wall steel up to 8mm, plastic up to 12mm, and stainless steel up to 6mm, making it perfect for lightweight projects. The ZD400 model specializes in larger pipes from 75-400mm, with the capability to cut wall steel up to 10mm and plastic up to 35mm, suited for industrial-grade applications. Precision cold cutting technology ensures a stable cutting trajectory with an accuracy of ±0.05mm, thanks to 8 precision guide rollers. This method prevents high-temperature deformation and sparks, delivering smooth, burr-free cuts every time. Features an arched adaptive clamping device with a user-friendly adjustment handwheel, making it compatible with pipes from 15-400mm in diameter. Size adjustments can be made quickly and easily without the need for tools. Equipped with an ultra-hard steel saw blade rated at 93HRA, made from ultra-fine alloy steel with a bending strength of 1500MPa. This blade effortlessly cuts through super-hard materials like stainless steel and ductile iron, capable of slicing through a 6mm thick steel pipe in under two minutes. Versatile application across over 12 materials including stainless steel, PVC, galvanized, copper, and cast iron pipes. Ideal for a wide range of projects in water, electricity, gas, and decoration sectors, ensuring universal utility.
