Our Orbital Trajectory Milling Cut-off Unit is custom-engineered for ERW pipe production lines to perform high-speed continuous cold cutting on small and medium-diameter steel tubes. Offering excellent universal compatibility, it synchronizes smoothly with orbital milling cutoff units, flying cutoff equipment, ERW tube mills, and complete production lines dedicated to OCTG casing and tubing.
Designed with a shear-type cold cutting mechanism and fitted with an integrated full cooling and lubrication system, the machine expels most cutting heat through metal swarf. This design ensures tube workpieces and cutting blades stay at low operating temperatures across the entire cutting process.
Running at high linear speeds, it delivers cleanly squared, burr-free, distortion-free tube ends with exceptional dimensional precision. Tailored for high-volume pipe producers, this equipment substantially increases overall line throughput while sustaining consistent premium quality of finished tubes in mass production.

مبدأ العمل
Different from traditional abrasive hot cutting discs that generate massive frictional heat and sparks, this single cold saw blade 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.
