1. Precision of wooden door engraving machine:
Usually, small size machine engraving 1mm Chinese characters, or large engraving machine engraved 1.5mm small words, under the magnifying glass to see very clear.
Two: spindle motor and power.
Spindle motor is an important component of computer engraving machine, and its function has a vital influence on the function of computer engraving machine. The processing main shaft is generally divided into two types: precision machining spindle and high power block spindle.
1. The features of precision machining spindle are low noise, high speed and height, suitable for the processing of extremely precise workpieces, such as seals, nameplates, and chest gifts. This kind of motor is generally high speed frequency conversion motor, the power is small, as below 250W. Defect is the ability to block thick data is poor, do not block the thicker data.
2, high-power block the spindle, first used in the block, high power, is characterized by large power, cutting ability is strong, especially suitable to cut yu, three stereoscopic word, of course, also can be made the breastpiece, nameplate, seals, etc. According to the characteristics of the motor, such large power spindle can be divided into brushless high-speed communication motor and brush communication motor. The first difference is:
A, brushless frequency conversion motor has high speed, and the variable speed is 70060000 RPM, while the maximum speed of brush communication motor is not more than 24000 RPM;
B. Brushless frequency conversion motor has high rotation precision, small wear and low noise, and makes noise greatly lower than the brush communication motor;
C, locked-rotor characteristic frequency conversion brushless motor is good, because the frequency converter with current limiting circuit, locked-rotor not burning motor for a short period of time, and a brush communication machine in the overload operation or locked-rotor decay quickly smoke, and no correction;
D, selection of frequency conversion brushless motor variable frequency speed regulation control skills, is a professional commodity, taking long, manufacturers supply 1 year free replacement, the future will also be able to pass to replace high speed bearing for motor protection, communication and a brush motor because of using electricity Zagreb life spans about 300 hours will have to replace carbon brush motor or motor, so the carbon brush motor generally does not guarantee a day communication.
3: dust collection device.
Wooden door engraving machine will produce a lot of dust when working. The engraving machine should be designed with good dust collecting device.
Four: adsorption fixed table.
Wood engraving machine carving very fast in the process of work, the strength is very large, common fixture fixed way hard to fixed, so the choose and buy woodworking engraving machine should be equipped with a vacuum adsorption platform, to a fixed carving materials.
