The TJ series small desktop laser marking machine is a compact desktop fiber laser marking system designed for users who need a simple, flexible and convenient marking solution. It uses a 1064nm wavelength fiber laser, which allows it to mark iron, copper, aluminum, gold and silver as well as non-metallic materials such as PC, ABS, PVC and PC+ABS. The machine is widely used in industries including 3C, automotive parts, electronic components, integrated circuits, electrical appliances, precision instruments, hardware products, building materials, watches, jewelry and arts and crafts.

Output power is available at 20W, 30W, 50W or 60W depending on the model (TJ-20Z, TJ-30Z, TJ-50Z and TJ-60Z). Beam quality M2 is 1.5 for the 20W and 30W models and 1.8 for the 50W and 60W models, with pulse repetition frequency of 27–60 kHz and 40–80 kHz respectively. Engraving speed reaches 10,000 mm/s and engraving depth is up to 1 mm depending on power and time, within a marking range of 100–150 mm. Repeatability is ±0.002, the minimum marker line width is 0.1 mm and the minimum character height is 0.15 mm.

The machine is built for portability. The complete unit weighs about 11.3 kg with external dimensions of 285 × 366 × 588 mm, and both the column and the light path can be disassembled and packed at any time by loosening the screws, making the machine easy to transport and store. The column can also be adjusted freely on the marking table so the marking position can be arranged to suit the workpiece. The laser head assembly uses a double red light metal galvanometer with built-in marking indication that requires no adjustment, and a stowed rotary lift with manual rotary docking. Control is through a Windows computer (not included; the customer supplies their own) running marking software with multi-language switching, and cooling is built-in air cooling with a system power supply of 500W on 220V/50Hz, with 110V supported. Oil mist and condensation must be avoided in the operating environment.
