What indicators need engraving machine when buying reference?

Choose want speed or precision carving machine, engraving machine performance evaluation of the two important parameters, is the speed and accuracy. Be short of one cannot, both supplement each other. Do not have your cake and eat it. The same device, can pursue its precision, also can be the pursuit of its speed, or to its optimal ratio. Configuration, of course, the higher the machine and the higher the overall performance, but also more expensive. In order to buy the highest cost-effective machine, you need us to understand that our items are carved with high precision. Moreover, time is money, speed efficiently to earn more money. Spindle motor to should consider the following: 1, whether the spindle radial force. Is the main reference whether high-speed cutting a hard material. Some spindle only at very low speed cutting hard material, otherwise the spindle performance will be a serious turn, after a period of time effect the precision of the spindle, and even failure. 2, whether the spindle motor with high precision bearings, if not bearing with high precision, performance is overheating after high-speed spindle electric captain time, affect the service life of the spindle motor. 3, if you want to pursue the processing efficiency, process as well as speed, turning big at the same time, such as processing solid wood materials, you need 2. More than 2 kw power spindle motor. 4, different rotating speed, especially at high speed, the sound is uniform and harmonious.
