Woodworking engraving machine is a relatively large family in the current engraving machine. There are also many classifications. There are many kinds of different working methods according to different needs. Here are not listed one by one. Today our focus is on one of them. The introduction and understanding of the wood mold engraving machine, the wood mold engraving machine is an engraving machine that appears according to the demand for different needs. Next, follow the CNC network Xiaobian to understand what the wood mold engraving machine is related to the function of the wood mold engraving machine!
The wood mold engraving machine engraving is a combination of drilling and milling processing from the principle of machining. The various data input modes of the engraving machine are more than necessary. Because the engraving machine has a wide range of applications, it is necessary to understand the most suitable range of applications for various engraving machines. The low power is only suitable for two-color boards, architectural models, small signage, three-dimensional crafts and so on. Because the power is too small, it greatly affects the scope of its application. The high-power engraving machine can do things like a low-power engraving machine. Ideal for large cuts, reliefs, and engravings.
In the CNC machine tool of wood mold engraving machine, the electric spindle usually adopts the frequency conversion speed regulation method. There are three main control modes: common variable frequency drive and control, vector control drive drive and control, and direct torque control. The common frequency conversion is scalar drive and control, and its drive control characteristic is constant torque drive, and the output power is proportional to the rotational speed. The dynamic performance of ordinary variable frequency control is not ideal. The control performance is not good at low speed, the output power is not stable enough, and the C axis function is not available. However, it is cheap and simple in structure, and is generally used in grinding machines and ordinary high-speed milling machines.
The vector control technology mimics the control of the DC motor, and is oriented by the rotor field. The vector transformation method is used to realize the drive and control, and has good dynamic performance. The vector control driver has a large torque value at the beginning of the start, and the electric spindle itself has a simple structure and a small inertia, so the starting acceleration is large, and the allowable limit speed can be instantaneously achieved after starting. This kind of driver has two kinds of open loop and closed loop. The latter can realize the feedback of position and speed. It not only has better dynamic performance, but also can realize C axis function. The former has poor dynamic performance and does not have C axis function. But the price is cheaper.
Direct torque control is a new type of high-performance AC speed control technology developed after vector control technology. Its control idea is novel, the system structure is simple and clear, and it is more suitable for high-speed electric spindle drive, and can meet high-speed electric spindle. High speed, wide speed range, high-speed instantaneous quasi-stop dynamic characteristics and static characteristics have become a hot technology in the field of AC transmission.
