The china laser pointer is more expensive

Body to avoid entering the range of the beam and its reflection. Remove unnecessary reflective materials (such as: metal material) next to the objects of their work. Processing object next to the best for the appropriate cover. The laser body to avoid the erection of the eye height of just people. Note the ventilation or exhaust position of the laser processing environment. Engraving machine to select the five points. The choice of format size customers should be based on business needs and financial situation, to choose your own engraving machine the size of the model and its power. The spindle motor is a key component of computer engraving machine, its performance has a critical influence on the overall performance of the computer engraving machine. Therefore, thechina laser pointer is more expensive.
Machining spindle is usually divided into two categories: precision machining spindle, and power cut off the spindle. Precision machining spindle is characterized by low noise, high speed, height, suitable for processing, in particular fine workpiece, such as seals, nameplates, badges and other gifts. Such motors are usually for high-speed frequency conversion motor, less power, in 250W following. The drawback is less able to cut thick materials, are not cut thicker materials. Cut off the high-power spindle, mainly used to cut, carved high-power, power, cutting ability, especially for cutting Yu, three three-dimensional character, of course, can also create badges, nameplates, seals. The laser module utilized by thechina laser pointer is very advanced.
Such high-power spindle motor characteristics generally can be divided into brushless frequency high-speed AC motor and brush AC motor, the main difference is: high speed brushless frequency conversion motor, variable speed range of 70.06 million rev / min, and the general brush exchange maximum speed of the motor is not ultra-24000 rev / min: high precision brushless frequency conversion motor rotation, wear, low noise, make noise significantly lower than the brush AC motor; brushless frequency conversion motor stall characteristics, due to the inverter special limiting circuit, short-term stall not burned the motor control mode and speed options: control methods can be divided into three: all the computing work to complete computer-controlled engraving machine computer is at work other layout work, such waste may be solid computer misuse. Here will introduce the difference between the industrial level and toy level of china laser pointer.
MCU control, the controller of this layout, but you can not turn off the computer engraving machine work at the same time, 7 a computer which is actually equivalent to savings and reduce the waste caused by the misuse of the computer. USB port to transfer data, the system has a memory capacity of more than 32M. After saving the file, immediately completely out of the computer, turn off the computer or other typesetting. In this way greatly improves the efficiency of the engraving machine. Large format engraving machine must be widened imports square rail, its load capacity and accuracy to maintain the capacity is more than 30 times the cycle guide to ensure a high-quality high-speed engraving machine. The toy level ofchina laser pointer has the relatively lower requirements.
The small-format machine engraving 1mm Chinese characters, or large format engraving machine engraved 1.5mm small print under a magnifying glass to be seen very clear. Laser engraved on the correct installation and commissioning of the machine. A lot of people in the beginning of the use of laser engraving machine, laser engraving machine can be assembled, not to mention the debugging, to address this issue, the laser light Yue experts specially the author reminds the laser engraving machine users, before the use of laser engraving machine, be sure to first machine installation and debugging good. Here is the installation and commissioning. The difference of green laser pointer will be showed in such various indices as the using temperature, using lifetime, reliability and safety and so on.
