Tube and sheet laser cutting machine Superfast ST series - detail pictures

Heavy-duty welded bed frame

The bed frame is welded using thick square tubes and reinforced internally to enhance structural strength and tensile resistance.It undergoes high-temperature annealing and natural aging treatment to eliminate welding stress, prevent deformation, reduce vibrations, and ensure excellent cutting precision.（laser cutter for steel）

Rotary

Standard 6m long rotation axis
Double chuck, supporting diameter 20-220mm
Fast servo motor drives rotation and rear card movement
One machine for two purposes, simple, stable and efficient

High speed pneumatic chuck

Processing range Ø20-Ø220mm
Limiting speed 300r/min
High stability

Laser Cutting head

Autofocus function, which automatically adjusts the focal length according to the thickness of different materials to ensure cutting quality and efficiency
Dual water cooling circuit system, it effectively reduces the operating temperature of the laser head and improves the stability and life of continuous work.
With IP65 dustproof performance, it effectively prevents dust and particles from entering the laser head and protects key components from pollution and damage.

Control System

The Bochu advanced control system designed specifically for the plate-tube integrated laser cutting machine has multi-functional cutting support, high-precision motion control, user-friendly interface and real-time monitoring and adjustment capabilities. Its automation function and stability ensure efficient production and cutting quality, and it is suitable for all kinds of metal processing needs, and is an ideal choice for improving production efficiency and cutting accuracy.

Fast and stable drive system

Using Japanese Yaskawa Electric, Japanese Fuji Electric or Inovance Motor, high precision, no step loss, high torque, low noise, using Taiwan yyc/Germany herion gear and Japanese shimpo/French motovario/Germany lead reducer, the machine positioning accuracy reaches 0.02 mm（laser cutter for steel）

Shipping methods

1 set of ST3 can be packaged in 1 40HQ standard container. We can enable rush delivery and usually charge significantly reduced freights. After arrival, users may assemble all together by using quick insert. No waiting for new installation.
