Engraving machine working principle and system classification

Engraving machine engraving machine working principle: by computer engraving machine, engraving machine controller, the host of three parts. Is a special sculpture through computer configuration software to carry on the design and layout, and the design and layout of information by the computer automatically sent to carving machine controller, and then by the controller can convert the information to drive stepper motor or servo motor with a power signal, Pulse sequence) , control engraving machine host generation X, Y, Z three axes carving knife subgrade diameter. At the same time, the engraving machine engraving head spins, by processing materials configuration tool, for fixed on the host workstation's processing materials for cutting, carving it out in the computer design of various plane or three-dimensional relief graphics and text, to realize the automatic carving homework. Engraving machine system classification: 1 + stepper motor, stepper drives stepper system is currently on the market to use, and most popular of the drive system is a three-phase hybrid stepping motor, accounted for more than 90% of market share, investigate its reason is cheap, deserve to go up the thunder after the high subdivision driver effect is good. But obvious flaws, such as: resonance, improve torque to reduce noise, rotational speed, easy to work long hours throw step, motor temperature rise too high. 2, mixed servo driver and motor servo in domestic use has not been popular, investigate its reason has a lot of, hybrid servo manufacturers abroad do not much, but the price is not very big advantage in comparison to relative to the ac servo, can only be used in some special industry. Improvements are: to improve the performance, reduce fever, reduce resonance. 3 + ac servo motor, ac servo driver, ac servo in the use of engraving machine or less, the main reason is that the price is higher, and the application of ac servo for the structure of machine tools, electrical equipment, control system, drive system has certain requirements, like barrel principle, the board decided the shortest bucket of water, because of some ac servo is generally applied to high-end models. Ac servo is: fast response, large torque, high speed, high precision, less heat, continue to work long hours, the complete alarm system and so on. Weakness: the servo parameters of different devices with different adjusting parameters requires a high level of technical engineers.
