ACME LT-12055TNKA Heavy Duty Four Chucks Tube Laser Cutting Machine
The standard loading length is available in 9m + 9m and 12m + 12m, with other customized lengths available upon request. It supports chuck diameters of 360mm, 550mm, 650mm and 850mm. All chucks are independently developed by ACME with an 8-cylinder structure, providing twice the clamping force compared to conventional 4-cylinder chucks on the market, ensuring stronger stability and longer service life.
The machine excels in heavy pipe cutting, complex profile cutting and bevel cutting, including dual-Y, dual-X and various bevel processing with high precision.
It is widely used in demanding industries such as petroleum engineering, large steel structure fabrication and other heavy industrial applications.

Product Advantages of CNC Pipe Cutting Machine
1. Eight-Cylinder Chuck Structure: Stable & Precise Clamping
This pipe cutting machine is equipped with a proprietary eight-cylinder power chuck structure, which is a breakthrough upgrade compared with traditional single-cylinder or double-cylinder chuck designs. The eight independent cylinders work synchronously to achieve uniform and high-strength clamping force on pipes of various specifications, including round pipes, square pipes, rectangular pipes and special-shaped pipes.
This structure eliminates pipe deformation, sliding and offset during high-speed cutting and heavy-duty processing, effectively avoiding clamping damage to thin-walled pipes and ensuring firm fixation for thick-walled and heavy pipes. It delivers ultra-stable clamping performance, greatly improves cutting accuracy, reduces material waste caused by clamping errors, and adapts to diversified pipe processing requirements in industries such as metal fabrication, construction, machinery manufacturing and automotive.
2. Heavy-Duty Welded Bed Made of Thick Steel Plate: Ultra-High Rigidity & Durability

The machine bed is constructed with high-thickness steel plates through integrated thick plate welding technology, followed by high-temperature aging treatment and precision finishing to completely eliminate internal stress. This heavy-duty welded bed features exceptional rigidity, stability and shock resistance, far superior to cast iron beds or thin-plate welded beds on the market.
It effectively resists vibration and deformation during long-term high-intensity operation, maintaining overall machine stability and processing accuracy for years without deviation. The thick plate welded structure enhances the machine’s load-bearing capacity, prolongs service life, reduces maintenance frequency, and ensures consistent high-quality cutting even in harsh industrial production environments, perfectly meeting long-term continuous production demands.
3. High-Configuration Servo Motor System: Efficient & Precise Power Support

The machine is driven by a complete set of high-quantity premium servo motors for all key moving parts, including feeding, clamping, cutting and rotating mechanisms. Each servo motor features high precision, fast response speed, low noise and stable operation, providing independent and accurate power support for every movement link.
Compared with machines equipped with fewer servo motors or ordinary motors, this high-quantity servo configuration realizes fully automatic, high-precision linkage control of the whole machine, ensuring smooth and stable operation, faster cutting speed, higher positioning accuracy and lower error rate. It significantly improves production efficiency, achieves smooth and burr-free pipe cutting ends, and supports complex cutting processes such as angle cutting, groove cutting and special-shaped cutting, making the machine highly adaptable to high-end and high-precision pipe processing tasks.
