How to choose the CNC engraving machine

A carving machine there are many choices, how to choose a suitable for your easy to carve, Shanghai professionals gives several matters needing attention.
By the principle known engraving machine, an important standard to measure the load ability is to uphold the torque. Adhere to the torque is also called static moment, is the stepper motor power but there is no rotation, the stator locked rotor torque. Engraving machine because the stepper motor torque at low-speed operation close to adhere to the torque, and the stepper motor torque and fast decay with the increase of the speed, the output power is increased with speed change, so that adhere to the torque is a measure of the load of step motor to the most important parameters of A.
The number of phases engraving machine different performance on the stepper motor are also different. Compared with two-phase stepper motor low cost, low speed large torque vibration, high speed landing fast, engraving machine suitable for high speed and precision of war stability request not high place; three-phase stepper motor speed performance is good, the maximum speed than the two-phase stepper motor high thirty percent to 50, suitable for high speed and the precision war stability request higher place; and the 5 phase stepper motor and better than the 3 phase stepper motor, but the production cost is high, so it is suitable for low-speed period of war and precision stability request high places. In the CNC engraving machine choice, should follow a principle of successively. The first election after the selected drive motor, finally find the matching step motor. In the choice of drive and the fine fraction, pay attention to the best not to choose the step state, because of the step state great vibration; try to choose a small current, high inductance, low voltage motor drive; in practice by using speed and accuracy are usually higher for war stability request not high places, do not choose high subdivision drive, so that cost savings; in short, in the selection of fine fraction should practice, consider the speed, load torque range, speed reducer, precision request, set the status of vibration and noise of request etc.. Engraving machine to carry out from time to time, changing people's life, in the face of a new round of opportunities and challenges waiting for the carving life more exciting.
