CNC Router Buying Guide: How to Buy CNC Router
There are various engraving machines on the market to choose from, generally the CNC router machine can be divided into metal processing type and non-metallic processing type. Non-metal engraving machines can also be subdivided into wooden engraving machines, stone engraving machines, foam engraving machines, advertising engraving machines, etc.
Different types of engraving machines have their appropriate processing materials and applications, and one machine is not recommended for a variety of different materials. If you use the stone engraving machine to engrave wood products, the working result will not be as perfect as expected, so it is quite necessary to confirm the very type of engraving machine in accordance with the industry and processing materials;
CNC Router Machine Type
Generally, plates of 1220x2440mm are taken for the wooden door and window industry, the standard model of engraving machine can meet the requirements such as JeesunCNC 1325 engraving machine; For complex process requirements such as pattern engraving, relief carving, etc which will have to be engraved by different tools, ATC engraving machine or multi-head engraving machine are a good choice which can automatically switch different tools according to different working requirements, the work efficiency is higher;
If you want to process cylindrical or other profiled workpieces, such as tables and chairs legs in European furniture, stair handrails, bathroom ware, casting, automobile, yacht and other curved processing, the 5-axis five linkage machine center can be taken. For furniture industry which requires bulk processing of wood relief, multi-headed woodworking engraving machine or multi-process machine center are good choice;
If the sheet is relatively large, the material will be drumed even the four corners are well fixed, causing imperfect or non-standard engraving, and the vacuum adsorption will have to be taken for the woodworking engraving machine.
Stepping motors are performed based on pulse and usually do not receive feedback from actual location. Compared with stepper motor, the servo motor is more powerful with parameter memories, fault self-diagnostics and analysis functions, it will continue to monitor the correct location and can provide higher torque capabilities, though higher costs.
CNC Router Spindle
The spindle has a variety of different types and power to choose from. Generally, it can be divided into water-cooling spindle, air-cooling spindle, etc. The cooling effect of the water-cooling spindle is good, but the maintenance is complex and the cooling water will produce scale which will erode the tube parts inside the main shaft; the maintenance of air-cooling spindle is much easier, but the cooling effect is not as good as the water-cooling spindle.
At the same time, spindles of different powers can be selected for different materials, for example, 3kW spindle or even smaller ones can be taken for engraving of acrylic plates which have smaller vibration and better performance, the surface is smooth and the precision is high; For stone processing industry, bathroom industry and mold industry, 10KW spindle or even bigger ones are recommended which have big cutting strength and high processing efficiency;
The transmission form mainly includes ball screw, rack gear and guide rail; the ball screw is mainly applied to small engraving machines, such as advertisement engraving machine, its operating accuracy is high, but the speed is slow; The rack gear has higher running speed, but the accuracy is slightly poor than ball screw; the guide rail has a variety of different models, among them, Germany, Japanese and Taiwan rails are widely selected,such as Japanese THK automatic lubrication guide, etc.
