How to Assemble a CNC Router Machine?

What is CNC router machine?

CNC router machine is an automatic processing equipment developed on the basis of general milling machines. The processing technology of the two is basically the same, and the structure is also somewhat similar. CNC milling machines are divided into two categories: without tool magazine and with tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

CNC router machine features

1. The parts have strong adaptability and flexibility, and can process parts with particularly complex contours or difficult to control dimensions, such as mold parts, shell parts, etc.
2. CNC router machine can process parts that cannot be processed by ordinary machine tools or are difficult to process, such as complex curved parts described by mathematical models and three-dimensional space surface parts.
3. CNC router machine can process parts that need to be processed in multiple processes after one clamping and positioning.
4. High machining accuracy, stable and reliable machining quality, the pulse equivalent of the numerical control device is generally 0.001mm, and the high-precision numerical contro system can reach 0.1μm. In addition, the numerical control machining also avoids the operator's operating errors.
5. The high degree of production automation can reduce the labor intensity of the operator. Conducive to production management automation.
6. High production efficiency, CNC milling machines generally do not need to use special process equipment such as special fixtures, and only need to call the processing program stored in the CNC device, the clamping tool and the adjustment tool data when replacing the workpiece, thus greatly shortening the production cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the process highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed rate of the CNC milling machine are infinitely variable, so it is beneficial to choose the best cutting amount.

Installation of CNC router machine

The installation of CNC machine tools generally includes foundation construction, machine tool firewood boxes, hoisting in place, connection and assembly, and commissioning and debugging. CNC machine tools should be installed in strict accordance with the requirements of the product manual. The installation of small machine tools can be carried out as a whole, so it is relatively simple. Large and medium-sized machine tools are much more complicated because they are disassembled into several parts during transportation, and require reassembly and adjustment during installation. The installation process of the machine tool will now be introduced separately.

Foundation construction and machine tools in place

Before the machine tool is installed, the foundation of the machine tool should be laid according to the machine tool foundation diagram provided by the machine tool factory. The position and foundation of the machine tool are of great significance for maintaining the accuracy of the machine tool and running it safely and stably. The location of the machine tool should be far away from the vibration source, avoid sunlight, and place it in a dry place. If there is a vibration source near the machine tool, anti-vibration trenches must be set around the foundation. Make a reserved hole at the location where the anchor bolt is installed. After the machine tool is unpacked, first take out the random technical documents and packing list, check whether the parts, accessories and other materials in each packing box are complete according to the packing list, then carefully read the machine tool manual, and install it according to the requirements of the manual. Put a number of pads used to adjust the level of the machine tool, and then hoist the basic parts of the machine tool (or small complete machine) on the foundation. At the same time, place the anchor bolts in the reserved holes as required.

Machine tool connection and assembly

Machine tool connection assembly refers to the process of reassembling the scattered machine tool components into a complete machine. For example, the connection between the main bed and the extended bed, the column, the numerical control cabinet and the electrical cabinet are installed on the bed, the tool magazine manipulator is installed on the column, and so on. Before connecting and assembling the machine tool, first remove the anti-rust paint on the connecting surface and the moving surface of the guide rail, clean the outer surface of each part, and then connect and assemble the cleaned parts into a complete machine. For the connection and positioning of components, use the random positioning pins and positioning blocks to restore each component to the position before disassembly, so as to facilitate further precision adjustment.

ATO CNC can be widely used for engraving soft materials such as plastic, wood, acrylic, PVC, PCB, etc. It has 3 axes, can be directly connected to a USB desktop computer, can realize flat and three-dimensional engraving, and the working area ranges from 50mm² ~ 600mm².
