Stone carving machine spindle are what kind?

Stone carving machine spindle motor is an important parts of computer engraving machine, its function of computer engraving machine has a vital influence the function of the machine. Machining spindle generally fall into two categories: precision machining spindle and high power block the spindle. 1, precision machining spindle is characterized by low noise, high speed, high precision, suitable for special precision of workpieces, such as seals, nameplates, badges gifts, etc. This kind of motor is commonly high speed frequency conversion motor, power is small, typically below 250 w. Defect is the detection of thick information ability is bad, not appropriate to block the thicker material. 2, stone carving machine power block the spindle, first used for carving block, high power, is characterized by large power, cutting ability is strong, special cutting, three-dimensional words, right, of course, also can be made the breastpiece, nameplate, seals, etc. Such high power spindle generally can be divided into, according to the features of motor brushless frequency motor and brush with communication, high-speed communication: is the primary difference between A and frequency conversion brushless motor speed is high, the speed change size from 700 to 60000 RPM, and generally have A brush motor high speed communication does not exceed 24000 RPM: B, frequency conversion brushless motor rotation of high precision, wear small, low noise, the noise is much lower than motor brush communication; C, locked-rotor characteristic frequency conversion brushless motor is good, because have a special current limiting circuit on frequency converter, 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 repair; D, selection of frequency conversion brushless motor variable frequency speed regulation control skills, is a professional product, taking long, manufacturers supply free replacement and 1 year later will also be able to pass to replace high speed bearing for motor protection, communication and a brush motor because of using the motor 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. Stone carving factory production of stone engraving machine, wood engraving machine, CNC engraving machine control method can be divided into three types: A, all the operation of work completed by computer control. B, choose single chip microcomputer control. C, use USB port to transmit data, system has more than 32 m memory capacity.
