In the above we mentioned the basic components of the CNC router. If you want to know more about the structure of CNC router, you can get more information here.
1. Bed structure
Including gantry, base, table, spindle unit, control cabinet, etc.
2. CNC router spindle
Spindles are divided into air-cooled spindles and water-cooled spindles according to different cooling methods. When processing different materials, the power and speed of the spindle are also different, which should be selected according to the actual processing materials and work efficiency requirements.
If you are an advertising company and the materials to be processed are relatively soft materials such as acrylic, wood, plastic, etc., the spindle power can be selected from 1.5KW-3.0KW. The spindle power of the woodworking CNC router needs to be selected according to the hardness of the wood to be processed, generally between 2.2KW-4.KW. Because of the high hardness of the material processed by the stone CNC router machine, the spindle power is relatively high, generally between 4.5KW-7.5KW.
3. Drive system
The drive system is the drive components and motion units that perform machine operation, including the spindle drive unit, spindle motor, feed unit and feed motor, guide rails, sliders, etc. Through the command signal issued by the control system, multiple drive units work together to complete the positioning and processing of the plane or 3D workpiece.
4. Motor
CNC router motors have stepper motors and servo motors. The main function is to convert the pulse signal of the numerical control device into the movement of the moving parts of the cnc wood router, so that the machine can work according to the instructions of the numerical control device.
Stepper motors are suitable for small size or CNC routers that do not require too high processing speed, which is an economical solution for general engraving and cutting needs. Servo motors are suitable for CNC routers that large scale or require high-speed processing, and have better processing results for applications that require improved positioning accuracy and resolution.
5. Inverter
A frequency converter is a power control device that converts a power frequency power supply into another frequency by using the on-off function of a power semiconductor device.
6. Rails
There are round rails and square rails. The square guide rail can withstand high load pressure in four directions, with high positioning accuracy and small friction coefficient, which can maintain the walking accuracy for a long time. Currently, all CNC routers produced by our factory use square guide rails.
7. Transmission mode
The CNC router has two ways of screw drive and rack and pinion drive. Small CNC machine tools such as 6090 CNC router and 6012 CNC router adopt screw drive mode, which has higher precision. Large CNC machine tools such as 1325 CNC router and 1530 CNC router adopt rack and pinion transmission mode, which can provide higher running speed without compromising accuracy.
8. Control system
The control system is the core of the CNC machine tool, including the control board, the control panel, the data transmission line, the display and the corresponding digital program. It is used to complete the storage of information, the transformation of data, the interpolation operation and the realization of various control functions.
9. CNC router table
There are aluminum T-slot workbench, vacuum adsorption workbench, T-slot and vacuum combination workbench. The aluminum T-slot workbench has a good effect on the fixation of small-sized sheets or hollow sheets. The vacuum adsorption table is more convenient and efficient for fixing large-sized sheets or irregular sheets.
10. Other auxiliary devices
Rotary axis for 3D machining of cylindrical materials. The vacuum cleaner, during the engraving and cutting process of the machine, collects other wastes such as sawdust through the vacuum tube into the dust bag to maintain the cleanliness of the workshop environment. Water-cooled circulation device, pneumatic device, tool changer, tool setting instrument, sensing device, etc.
Before purchasing a CNC router, knowing more about the machine configuration can make the CNC router more suitable for workshop processing needs and create more value for users.
