Engraving machine works:
The engraving machine is composed of three parts: computer, engraving machine controller and engraving machine main unit. It is designed and typeset by special engraving software configured in the computer, and the design and typesetting information is automatically transmitted to the engraving machine controller by the computer, and then the controller converts the information into a stepping motor or a servo motor. The signal with power (pulse train) controls the engraving machine to generate the engraving path of the three axes of X, Y and Z. At the same time, the high-speed rotary engraving head on the engraving machine can engrave various plane or three-dimensional relief patterns and characters designed in the computer by cutting the machining materials fixed on the main table by the tool arranged by the processing material. To achieve automatic carving work.
Engraving machine system classification:
1, stepper drive + stepper motor
The stepping system is currently the most widely used and popular drive system in the market is a three-phase hybrid stepping motor, accounting for more than 90% of the market share, the reason is that the price is cheap, coupled with the Raytheon high-resolution drive After the effect is good. However, the defects are also obvious, such as: resonance, noise, speed increase torque reduction, long-term work is easy to lose steps, motor temperature rise is too high.
2, hybrid servo drive + motor
Hybrid servo has not been widely used in China. There are many reasons for this. There are not many manufacturers of hybrid servos in foreign countries, and the price has no great advantage compared with AC servos. It can only be used in some special industries. Improvements include: improved high speed performance, reduced heat generation, and reduced resonance.
3, AC servo drive + AC servo motor
The use of AC servo in the engraving machine is still relatively small. The main reason is that the price is relatively high. In addition, the application of AC servo has certain requirements for the structure, electrical appliance, control system and transmission system of the machine tool, just like the principle of wooden barrel, the shortest The board determines the amount of water in the barrel, and some AC servos are generally used in high-end models. AC servo has: fast response, large torque, high speed, high precision, less heat, long-term work, complete alarm system. Disadvantages: Different equipment should use different servo parameters to adjust the parameters to require a high level of technical engineers.
