Introduction of Mini CNC Router

Small routers are a type of machine designed specifically for amateurs, families, small and medium-sized studios or factories. In terms of basic functions and working principles of the machine, it is not much different from the industrial router. A variety of configurations can also be selected, but the design of the machine structure will be more compact. We also use a lot of aluminum alloy materials to make it as lightweight as possible while ensuring the structural strength for easy transportation and movement. In terms of CNC system and programming software, we use a self-developed improved version of the simplified system. The operation interface is simple and easy to understand, and non-professionals can quickly learn and use it. Users can choose different body materials (cast iron, aluminum alloy, square tube, etc.), spindles, cooling systems, rotating axes, table clamping types, servo motors, etc. Although this type of router is entry-level, we fully follow the industrial standards in terms of accessory quality and assembly process to ensure the durability, precision, and processing effect of the machine. And we will provide free design and programming software and detailed tutorials to help you from entry to mastery.

Type of Mini CNC Router

The basic configuration of entry-level small routers is a three-axis machine, namely the X-axis (horizontal left and right movement), the Y-axis (horizontal forward and backward movement), and the Z-axis (vertical up and down movement).

There are usually two types of control. DSP handle: directly connected to the machine, it can be independently controlled after transferring the drawings to the handle via a USB flash drive, but the function is relatively simple. Control card: built into the chassis, connected to the computer via a data cable, and operated and controlled using the corresponding software.

Classification by Processing Materials

• Woodworking router: mainly used for wood engraving, including hardwood, cork, artificial board, fiberboard, etc.

• Metal router: specially used for metal engraving, suitable for metal materials such as iron, copper, aluminum, stainless steel, etc.

• Stone router: mainly used for stone engraving, including marble, jade, artificial stone, ceramic tile and other materials.

• Multi-function router: this type of router is suitable for a variety of materials, such as wood, plastic, acrylic, PVC, glass, soft metal, etc.

Configuration of Basic CNC Router

How to Choose a Mini CNC Router?

1. First, we need to consider the material to be processed, such as metal, stone, wood, etc., and then choose different types of CNC routers. Metal and stone routers have a more solid mechanical structure and a larger spindle power, so their prices are usually higher than wood processing machines. However, these machines can process very hard materials, which means that they also have the ability to process non-metallic materials such as wood and plastic, and have a wider range of applications. You can choose machines with different mechanical structures based on your actual use needs and budget to avoid waste due to excessive configuration or insufficient processing capacity due to low configuration.

2. It is very important to choose the maximum table size and feed height of the machine according to the maximum size of your own product. If the processing format is too large, it will not only cause waste, but also increase space occupancy; if the format is too small, it may not meet the processing needs.

3. In terms of spindle power and motor selection, high-power spindles (2200W - 5500W) are suitable for long-term, high-intensity engraving operations; low-power spindles (800 - 1500W) are more suitable for lightweight fine engraving. As for the drive motor, if the product has high requirements for fineness, it is recommended to choose an AC servo motor with better precision control and more stable operation. At the same time, the selection of a higher precision ball screw can further improve the processing accuracy.

4. In terms of the choice of machine style, if you have a work platform, you can choose a desktop machine. This type of machine does not have a metal welding base underneath, and the ground feet are installed directly under the machine. The electrical components are usually integrated in a small box and connected to the machine through an aviation plug. It is very light and easy to move and carry. Table small routers are generally equipped with a base, and the electrical components are also integrated in it. Although the convenience of moving is not as good as that of desktop machines, its advantage is that it can be placed independently on the ground. It is also equipped with four adjustable height feet, so there is no need to worry about the uneven ground causing the machine to tilt or shake.

First Use Guide for Mini CNC Router

Installation of the machine

After receiving the machine, unpack it and first check whether the parts are complete. The equipment is generally shipped as a complete machine, and the installation is relatively simple.

For desktop routers, connect the control chassis to the machine in the order of the labels, ensure that the aviation plug is plugged in tightly, and tighten the screws to prevent short circuits caused by virtual connection of the line.

For machines with DSP handles, the control handle needs to be connected to the wiring board inside the chassis and the screws need to be tightened to prevent it from loosening.

For machines with control cards, a computer needs to be prepared, and the control board needs to be connected to the computer using a data cable.

If the selected engraving spindle is a water-cooled spindle, a circulating cooling water pump needs to be connected, and a bucket or a tool box (our tool box can be used as a bucket) needs to be filled with clear and clean water to ensure that the water level submerges the pump.

The last step is to prepare the power supply.

Power on and return to zero

Turn on the power switch of the router, and wait for the self-check of the inverter, driver and other electrical components inside the chassis to complete (the numbers on the screen no longer change) before starting the operation. First, click the "Back to Mechanical Origin" button in the control system. The machine will automatically adjust the coordinate axes (X, Y, Z axes) to the mechanical zero point. This step is critical to ensure that the router can accurately locate the coordinates in subsequent operations.

Load the engraving tool and the material to be processed

Select the tool suitable for product processing, use the wrench provided by the machine to insert the tool into the tool holder and tighten it in place.

If you are using this type of machine for the first time, it is recommended to first use the engraving tip that comes with the machine and use the fine engraving drawings provided by the supplier to test the machine.

Fix the engraving material firmly on the processing platform to ensure that the material does not move or shake during the engraving process. Note: If you use a pressure plate to fix it, remember not to press on the engraving processing area, otherwise the engraving tool will be damaged.

Load the engraving program and processing parameter settings

Load the designed drawing path into the CNC system, and then adjust the spindle speed and processing speed according to the hardness of the material and the processing technology to ensure processing safety and avoid damage to the tool and material.

It is recommended to adjust the spindle speed to the highest and the feed rate to 10%, and then gradually increase the engraving speed according to the processing situation. For the first processing, you can use the path simulation function to check whether the engraving path is correct on the computer; you can also do an empty process without loading the material first to observe whether the path is correct.

Tool setting operation

According to the path generated by the design drawing, determine the processing starting point of the engraving, usually the four corners or center of the engraving pattern. Manually move the X and Y axes of the router to the processing starting point of the workpiece, and then lower the Z axis so that it touches the surface of the material. Then clear the workpiece coordinate system in the CNC system and set this point as the processing starting point.

Engraving and finishing

After confirming that the engraving path and all parameter settings are correct, click to start the engraving program and the machine starts working. After the processing is completed, the machine will stop automatically (the spindle stops and the Z axis is lifted), without manual operation.

Daily Maintenance of Mini CNC Router

This type of machine has a relatively simple structure, so maintenance and upkeep are also very simple and convenient. Following the maintenance steps below can ensure the normal operation of the router, guarantee the processing effect, and extend the service life of the equipment.

Cooling system

For CNC routers that use water circulation to cool the spindle, before starting processing every day, it is necessary to check whether the cooling water is clean, whether the water level is higher than the water pump, and whether the water pump is working properly. Change the cooling water regularly to prevent the water temperature from being too high, which will cause the cooling effect of the spindle to decrease.

Daily cleaning

After daily processing, use a brush or dry rag to clean the grease and dust on the guide rails, screw rods, workbenches and other parts to keep the equipment clean and prevent dirt from affecting the processing accuracy and machine lubrication.

Note that do not use a wet cloth to directly wipe the machine guide rails, screw rods and electrical components to avoid rust or damage.

Regular dust removal

Regularly remove dust from hidden parts such as the inside of the router dust cover and the control cabinet to prevent dust that accumulates over time from entering the router and affecting the normal operation of the machine. You can use a vacuum cleaner or air gun for cleaning.

Transmission structure lubrication

Daily check to ensure that the lubrication system is working properly, and add lubricating oil to the oil pump in time to keep the guide rails, lead screws and other components in good lubrication.

If it is found that the sliding is not smooth or there is an abnormal sound, manual lubrication should be performed immediately, such as spraying lubricating oil with a brush or oil pot.

Inspection and tightening

It is recommended to check whether all screws of the router are loose every three months. If there is any looseness, tighten it in time to ensure that the machine parts are firmly fixed to avoid problems such as looseness affecting the processing accuracy or causing virtual connection of the line.

Line inspection

When maintaining and inspecting the line, be sure to cut off the power supply to ensure safety. Check whether the wires, cables, and plugs are damaged. If damaged, replace them in time.
