Advanced multi‑roll and rotary straightening technology delivers consistent ≤0.2 mm/m straightness, surface protection, and high throughput for carbon steel tubes used in hydraulics, construction, automotive, and general engineering. Why Carbon Steel Tubes Need Precision Straightening Carbon steel tubes (seamless or welded, grades such as 1020, 1045, 4140, STKM, etc.) are the backbone of hydraulic cylinders, structural frameworks, automotive components, and industrial piping.

Advanced multi‑roll and two‑roll straightening technology delivers consistent ≤0.3 mm/m linearity for tubes, bars, and profiles – meeting the tightest specifications in aerospace, automotive, medical, and precision engineering. Why 0.3mm/m Straightness Matters In critical applications, straightness is not a suggestion – it is a requirement. A deviation of just 0.3 mm per meter can mean the difference between: A hydraulic piston that seals perfectly vs. one that leaks A guide

Advanced hydraulic end‑forming technology delivers smooth, concentric, and surface‑protected points – essential for high‑yield cold drawing of steel, stainless steel, aluminum, copper, and specialty alloys. Why Precision Pointing Matters Before any tube or bar can be cold drawn to precise dimensions, its leading end must be reduced to a tapered “point” that passes through the drawing die and is securely gripped by the carriage. The quality of this point directly determines dr

Next‑generation CNC straightening with closed‑loop laser feedback, servo‑driven roll positioning, and automated material handling – achieving consistent <0.15 mm/m straightness for tubes, bars, and profiles without operator intervention. The Evolution of Straightening Technology Manual roll adjustment and visual inspection are no longer acceptable for today’s precision‑driven industries. Automatic precision straightening machines represent a fundamental shift: intelligent, cl
