CNC Router Buying Guide: How to Buy CNC Router
Working Requirement
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.
Driving Motor
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;
Transmission
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.
Operating System & Software
Different options of operating systems are available for CNC engraving machine, such as Syntec, OSAI, WeiHong, DSP, etc. The OSAI system has high expansion capacity and wide range of applications, it can be independently controlled by computer, and functional modules can be added at will; Syntec system is dedicated for woodworking engraving machine with high cost performance and moderate price;
Weihong system is generally used for CNC router machine with rack pinon transmission, it is characterized of high stability and low price, thus is a practical choice. The engraving machine should work with the appropriate software, such as CV and NC-HOPS software used in board furniture, ALPHACAM and POWERMILL are suitable for 3-axis or more.
Budget & Price Of CNC Router Machine
The company should choose the appropriate machine type according to its own budget and working requirements. If used in large-scale mass production, it is recommended to choose the machining center which have high production efficiency and can save labor cost, whiles for small-scale workshop, CNC router machine with rack pinon transmission can be better idea as the price is much lower and thus the cost-performance is much higher.
What Is The Cost of CNC Router Machine?
The cost of CNC router machine is closely related to its configuration. For example, CNC router machines can be divided into a variety of different types, such as small CNC router machine, standard CNC router machine, ATC CNC router, 4 axis CNC router machine, 5 axis CNC router machine, etc.
Though they have similar appearance & function, the actual configuration of those CNC engraving machines are quite different, also, the price, running accuracy, working speed and service life vary much. Important parts that matter include spindle, stepper/servo motors, drivers, CNC system, software, guide rails, rack pinon, etc. In addition, the machine bed has a very important impact on the price as different machine beds are available, including welded bed, cast bed, heavy-duty bed, light-duty bed. Generally, the heavier the machine is, the larger size the machine has, then the higher the price will be.
Besides, some other factors will have to be taken into consideration for overseas buyers, including tax, customs clearance, shipping fee, etc. In general, the market price of CNC router machine ranges from $ 3,000 to $ 100,000, depending on the actual type and the specific configuration of CNC router machines.
