What Is A CNC Router?

CNC router is a type of automatic machine tool with CNC system used for automatic carving, engraving, cutting, milling, drilling and grooving on different materials, such as wood, foam, stone, plastics, acrylic, glass, ACM, copper, brass, aluminum, PVC, MDF, etc. It is able to produce very precise and complex shapes and contours by machining materials with a tool. A CNC router machine achieves these results via at least three axes, called X, Y and Z. The X-axis is horizontal, the Y axis vertical, and the Z-axis refers vertical to the other two axes. These, seen figuratively, result in a so-called portal, which is why CNC routers with such a portal formation (X axis designed as a bridge) are often called portal milling machines. In addition, some milling machines have an A, B and C axis representing a rotation around the main axes X, Y and Z.

CNC router applications

How Does A CNC Router Machine Work?


Based on the introduction mentioned before, a CNC router machine is controlled by a computer. All necessary data, in form of so-called G-codes, are assembled into a CNC program. The G-codes consist of a ā€œGā€ followed by a number and type of milling work instruction. Since these codes are standardized, they may be based on a CNC router software used in almost all CNC router machines. When all data has been inserted and the CNC program is ready to play, the CNC machine can start its work. Manufacturers have added their own codes to the ISO G-codes. Therefore, various post-processors exist to generate ultimately "matching" programs from CAM programs for all different machines.


How does a CNC router machine work?


By a rotation of the respective tool, or a spindle adapted to the material, opposite the clamped workpiece, a cutting movement is produced, which is necessary for the desired chipping. This has already been determined in the records based on the G-codes. The movement of the CNC tool around the workpiece, ensures the predetermined shape. This can be done, depending on the design of the router, by displacement of the workpiece on a movable CNC router table. By using all axes, almost all workpiece geometries are possible e.g .:


3D models for architecture and model construction.

3D freeform surfaces.

Rotosymmetrical workpieces.

Lettering in 2D or 3D.

Engravings in 2D and 3D.

Threads.

Grooves.

How Much Does A CNC Router Cost?

How much does a CNC router cost?

The CNC router cost is closely related with its configuration. Although the CNC router appearance sometimes you feel you see Is almost the same, the realization of the function is the same of (cutting, hollow, lettering, plane carving, relief and so on), but according to the different configurations, its price, accuracy, speed, and service life will be different. 


The small CNC router price range: $2,500.00 - $5,000.00;

The standard CNC router price range: $3,000.00 - $10,000.00;

The ATC CNC router price range: $16,800.00 - $25,800.00;

The 5 Axis CNC router price range: $95,000.00 - $180,000.00;

The smart CNC router price range: $8,000.00 - $60,000.00.

What Are The Additional Costs And Fees Of CNC Router Machines?

In addition to the machine itself, you'll need to purchase a computer-aided design (CAD) software package in order to create the designs. Those usually run anywhere from $2,000 to $15,000. 

Training usually costs anywhere from $200 to $500 per day. Depending on the knowledge level of your staff, the process could take a few hours or several days. Installation also tends to run $200 to $500 per day.

Shipping starts at several hundred dollars and can cost up to $2,000.

Some dealers offer packages that bundle the cost of the machine, training, shipping, and installation. So be sure to ask if a package like that is available before deciding on your purchase.

How To Choose A CNC Router Table?

Table Types


The common types of CNC router tables include profile tables, vacuum tables, and adsorption block tables. CNC router profile table is also called fixture table. This kind of table is to directly press the workpiece with the pressing plate screw, which is suitable for cutting, hollowing and other processes, because as long as the air leaks, the vacuum adsorption cannot be absorbed. When to buy the profile table, customers can also choose the model that suits them based on the above two items when they buy the CNC machine. However, this is not entirely the case. If you use a tool with a relatively small diameter (such as a tool below 4mm) to cut, because the gap is small, some can also be vacuum-adsorbed on the table.


The vacuum table of CNC router is to put a density board directly on the table after the sealing tape is plugged, and the vacuum pump can be turned on to suck the workpiece. This table saves fixed time and is especially suitable for mass production in the wood door industry. Sometimes it is necessary to put a thin MDF board first. It is formed by wood fiber and glue under high pressure. There are ducts or gaps between the wood fiber itself and the wood fiber. Therefore, MDF board still has a certain of breathability. The purpose of placing the MDF board on the vacuum suction table of the CNC router is to prevent the milling cutter from hurting the work table. The pressure on the part close to the density board is much lower than the atmospheric pressure on the other side, forming the so-called negative pressure. Just like two pieces of glass together, it is not easy to separate the same principle. Once the seal is not tight, no negative pressure can be generated, that is, the pressure on both sides of the workpiece plate is the same, and it is easy to move.


Table Sizes


The most common CNC router table sizes include: 2' x 2', 2' x 3', 2' x 4', 4' x 6', 4' x 8', 5' x 10', 6' x 12'.

How To Choose A CNC Router Spindle?

The spindle is one of the most important components of a CNC router machine. The CNC machine generally needs to be equipped with a high-performance spindle to play its role. The quality of the spindle directly affects the processing speed and accuracy of the CNC router machine, so how to choose the right spindle?


1. The standard for judging whether the spindle is of high quality.


1.1. 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.

1.2. Whether the sound is uniform and harmonious when rotating at different speeds, especially at high speeds.

1.3. 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.

1.4. 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.

1.5. The standard configuration of the spindle of the CNC machine has different configurations according to the specifications of the equipment.


2. Choose the right CNC router spindle according to different applications.


2.1. The object engraved by the advertising CNC router 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.

2.2. 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.

2.3. 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.

2.4. The spindle power of the foam CNC router 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.

2.5. Due to the relatively large hardness of the metal CNC router 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.


3. The relationship between the spindle speed of the CNC router machine and the routing materials.


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 tool used in the CNC router machine 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.
