As the name suggests, CNC engraving machine is intelligent engraving equipment, and CNC cutting machine is intelligent woodworking cutting equipment.
The functions of CNC cutting machine and CNC engraving machine overlap, but their main purposes are still different. The cutting machine is mainly used for cutting, punching, slotting, edge milling, engraving and other functions of panel furniture. The engraving machine is mainly used for embossing, hollowing out, three-dimensional engraving and other functions of panel or three-dimensional parts.
In addition, in terms of price, the price of NC cutting machine is much higher than that of NC engraving machine. The factors affecting the price are mainly reflected in the differences of configuration and control system.
The engraving machine is generally equipped with an ordinary stuffy fire bed, the guide rail slider is generally type 20, the table structure is mostly aluminum alloy and soft PVC, the driving motor is mostly domestic stepping motor, and the frame is also a 1.25 purpose frame, with a relatively small modulus. The comprehensive embodiment of these configurations is that the operation speed is slow, and long-term heavy-duty operation will lead to out of step accuracy and even affect the service life of the machine.
At present, most cutting machines are equipped with double-layer weighted five face milling machine body. The stability and firmness performance is much higher than that of the engraving machine, and the total weight is twice or more than twice that of the engraving machine body. Most table structures are rigid fireproof PVC vacuum adsorption table. In order to meet the high-precision and heavy-duty work of plate cutting, 25 or 30 types of square rail sliding blocks are mostly selected, XY axis is equipped with reducer, Z axis is equipped with holding brake device and 1.5 mesh rack. The drive motor can also adopt domestic hybrid servo, closed-loop pure servo or imported servo motor, which can not only meet the standards of fast speed and high precision, but also meet the requirements of long-time processing and improve the processing efficiency.

In addition, for the spindle configuration of both, the engraving machine is generally a low-power water-cooled spindle or a low-power air-cooled spindle, generally 1.5KW, 2.2kW, 3.2Kw, etc. In order to cut plates at high speed, most cutting machines are equipped with high-power air-cooled spindles, such as 4.5kw, 6kW, 9kw, 12KW, etc.
