شركتنا Flying Cut‑off Machine for ERW Steel Tube Line, tailor-made for ERW pipe production lines, is specially engineered to deliver high-speed continuous cold cutting for small and medium-diameter steel pipes. Boasting excellent adaptability, it can be perfectly matched with orbital milling cutters, flying cutoff equipment, ERW tube mills, as well as complete production lines dedicated to OCTG casing and tubing.
Designed with a shear-type cold cutting mechanism and equipped with an integrated full cooling & lubrication system, the machine dissipates the majority of cutting heat via metal swarf. This structural design ensures both pipe workpieces and cutting blades maintain a low-temperature state throughout the whole cutting process.
Capable of operating under high linear speeds, the unit produces perfectly square pipe ends that are burr-free and distortion-free, coupled with outstanding dimensional precision. Ideal for high-throughput pipe manufacturers, this equipment significantly boosts overall line productivity while enabling stable, superior finished pipe quality in mass production.

مبدأ العمل
Different from traditional abrasive hot cutting discs that generate massive frictional heat and sparks, this شفرة منشار باردة مفردة relies on precision-ground hard cutting teeth to shear tube wall mechanically. During high-speed rotation and controlled feeding, cutting coolant continuously washes the cutting zone to dissipate heat instantly. All cutting thermal energy is taken away by swarf, so no heat-affected zone (HAZ), tube oxidation or thermal deformation occurs on pipe ends, realizing true cold cutting forming for tubular workpieces. Optimized tooth gullet design ensures smooth chip evacuation, avoiding tooth clogging during long-time high-speed tube cutting.
