High-Precision CNC Laser Cutting Machine for Ice Evaporator Tubes

The 1,500W fiber laser processes NdFeB up to 16 mm, stainless steel up to 6 mm, aluminum up to 4 mm, and brass up to 3 mm. Cutting speeds reach 20 m/min on 1 mm stainless steel and 18 m/min on 1 mm NdFeB, with nitrogen assist gas and calibrated nozzle/focus parameters for each material and thickness combination to produce clean, burr-free edges ready for downstream tube assembly.

Each 9-hole evaporator tube pattern completes in 14 seconds, supporting a verified output of 2,500 products per day from a single machine. Hiwin linear motors and Servotronix/Fuji servo drives provide the rapid acceleration and deceleration needed to maintain this cycle time without sacrificing positional accuracy, backed by Renishaw grating scales for closed-loop feedback.

The Eaststar natural granite countertop resists thermal deformation and vibration — two common causes of drift in high-speed laser systems. Combined with Doluyo water cooling and Tongfei climate control inside the electrical cabinet, the machine maintains consistent performance across shifts without frequent recalibration.

The Bochu CNC system running on a Dell industrial PC centralizes laser power, cutting head height, gas pressure, and motion control into a single interface. Operators load material through the dedicated side access door, select the programmed recipe for the target material and thickness, and start the cycle — reducing training time and the risk of parameter errors.

The fully enclosed cutting chamber with tinted viewing windows contains fumes and reflected laser energy. A prominently placed emergency stop, signal tower light for status indication, Schneider switchgear, and SMC pneumatic controls meet industrial safety and reliability requirements, allowing the machine to integrate directly into existing refrigeration tube production lines.
