What are the features of the spindle motor of the woodworking engraving machine?
High power cut spindle, mainly used for cutting, high-power engraving, is characterized by high power, cutting ability, especially for cutting words, three-dimensional characters, of course, you can also make chest cards, nameplates, seals and so on. According to the characteristics of the motor, this kind of high-power spindle can be divided into brushless frequency high-speed AC motor and brush AC motor:A brushless frequency conversion motor speed is high, the speed range is 700--60000 RPM / minute, and generally brushless AC motor maximum speed is not more than 24000 RPM / min.;B brushless frequency conversion motor has high rotation accuracy, small wear and low noise, and its noise is much lower than that of brushless AC motor;C, brushless frequency motor stalling characteristics, because the inverter has a special current limiting circuit, a short block not burning motor, and brush AC machine overload or stall will soon smoke burning, and can not be repaired;D, adopts frequency conversion speed control technology of brush motor, is a professional grade products, long service life, the manufacturers to provide 1 years free replacement, later also can be replaced by high speed bearing on motor maintenance, and brushless AC motor due to the use of motor life in about 300 hours to replace the motor or motor carbon brush, so carbon exchange the motor is usually a day will not warranty.
Fine machining spindle is characterized by low noise, high speed, high precision, suitable for processing particularly delicate workpieces, such as seals, nameplates, chest cards, gifts and so on. This kind of motor is usually a high speed variable frequency motor with less power and less than 250W. The disadvantage is that the ability to cut thick materials is poor and is not suitable for cutting thicker materials.
Spindle motor is an important component of computer engraving machine, and its performance has a crucial impact on the performance of computer engraving machine. Machining spindles are usually divided into two types: precision machined spindles and high power cut spindles.
