A CNC (Computer Numerical Control) router moving a tool to specific x, y, and z coordinates throughout the machine's available working area. A router or high-speed spindle with a cutting tool then removes material at the desired locations. Different cutting tools can be used depending on the material and the feature being machined. These tools can be manually changed or in the case of a more advanced machine, an ATC (Automatic Tool Changer) can swap out tools.
Advantages of Multi Head CNC Router
Precision and Accuracy
One of the most significant benefits of CNC router services is the unparalleled precision and accuracy they provide. Unlike manual routing, where human error can lead to inconsistencies and inaccuracies, CNC routers are computer-controlled, ensuring that every cut is made with utmost precision. This level of accuracy is crucial in industries where even the slightest deviation can have significant consequences, such as in aerospace and automotive manufacturing.

Complete CNC Router Parts
Frame
The frame supports the machine and provides rigidity to resist cutting forces. For larger routers, there may be a stand with legs or a welded base. Smaller models sit on top of a bench.
CNC Milling Machine Frames are most commonly made of aluminum extrusions. Other possibilities include aluminum plate, steel weldments, or even wood. To get an idea of a really stout frame that could be made of steel weldments and epoxy granite fill, click the link.
Table
CNC Router Tables can be made from a lot of materials. Shown are aluminum extrusions set up to create T-Slots. A router table might also be made of an expendable material like MDF. In that case, if it is intended to be expendable and replaced when needed, it is usually called a spoilboard or wasteboard.
CNC Router Tables may be bare, but often they will have features to facilitate workholding.
Spindle
Some say the Spindle is the heart of any CNC Machine. It certainly plays a major role in setting the performance potential of the machine.
At the low end, CNC Routers often use regular hand held routers or even Dremel-style tools as spindles. A step up from that is a spindle with a VFD. At the top of the heap are spindles set up for ATC–Automatic Tool Changers.
Ways
CNC Routers have at least 3 Axes. An axis consists of some kind of sliding ways and a drive system that motorizes the axis under computer control.
Axis Drive
The CNC Router's Axis Drive system converts rotary motion from a motor of some kind to linear motion to drive the axis on its sliding ways.
CNC Controller
A CNC Router's Controller is the electronics package that is responsible for executing a g-code programming and sending the necessary electrical signals to cause the motors to move properly to cut the part.
How To Choose A CNC Router Spindle
-Does the spindle motor use high-precision bearings? If high-precision bearings are not used, the performance is that the spindle motor will overheat after long-term high-speed rotation, which will affect the service life of the spindle motor.
-Whether the sound is uniform and harmonious when rotating at different speeds, especially at high speeds.
-Whether the spindle is under force in the radial direction. The main reference is whether it is possible to cut harder materials at high speed. Some spindles can only cut harder materials at very low speeds, otherwise the spindle performance will be severely lost, which will affect the spindle accuracy after a period of time, or even malfunction.
-If you want to pursue high processing efficiency, the processing speed must be fast, while the amount of knife is large, such as processing solid wood materials, you need a spindle motor with a power of 2.2KW or more.
-The standard configuration of the spindle of the CNC machine has different configurations according to the specifications of the equipment.
-The object cut by the small CNC machine is a relatively soft material, so the spindle power can be 1.5kw - 3.0kw. If you choose this way, you can achieve the purpose of routing and save costs.
-The power of the spindle motor of the CNC wood router can be selected according to the hardness of the wood to be processed, generally around 2.2kw - 4.5kw, this combination is also the most reasonable.
-The spindle power of the stone CNC machine is relatively higher, generally around 4.5kw - 7.5kw, the most commonly used is 5.5kw spindle motor.
-The spindle power of the foam CNC cutter should also be selected according to the hardness of the foam to be processed. The general power of 1.5kw - 2.2kw can meet customer needs.
-Due to the relatively large hardness of the metal CNC machine, the power of the spindle motor is generally 5.5kw - 9kw.
Too much power of the spindle motor not only wastes electrical energy, but also increases the purchase cost. If the power is too small, the routing power demand will not be available. Therefore, it is very important to choose a suitable spindle motor power.
The greater the hardness of the routing material, the lower the rotation speed of the spindle. This is actually well understood. Materials with high hardness need to be grinded slowly. If the rotation speed is too fast, the tool may be damaged. The higher the viscosity of the routing material, the higher the speed of the spindle used. This is mainly for some soft metals or man-made materials.
The diameter of the router bit is also a very important factor in determining the spindle speed. The practical tool diameter is related to the processing material and processing line. The larger the diameter of the tool, the slower the spindle speed will be. The determination of the spindle speed should be based on the use of the spindle motor. When the spindle speed decreases, the output power of the motor is also reduced. If the output power is low to a certain level, it will affect the processing, which will adversely affect the tool life and the workpiece. Therefore, when determining the spindle speed, pay attention to ensuring that the spindle motor has a certain output power.
