Definition and meaning
CNC (Computer Numerical Control) is a technology that uses computer programs to precisely control the motion trajectory, speed, force, and other parameters of machine tools or other automated equipment, in order to complete precision machining or operations. Simply put, CNC is equivalent to equipping machines with a "brain", which replaces manual labor with high-precision and repetitive tasks such as cutting, drilling, milling metal parts, etc. through pre written digital instructions (i.e. programs).
The emergence of CNC technology has made mechanical processing more precise and efficient, greatly improving production efficiency and product quality.
The principle of CNC technology is to control the movement and rotation of tools or workpieces in three or more coordinate systems through pre written programs, thereby accurately performing machining operations such as cutting, drilling, milling, etc. Compared with traditional manual operations, CNC technology has higher precision, stability, and repeatability, and can handle complex geometric shapes and fine details.
CNC technology is widely used in fields such as construction, industrial manufacturing, aerospace, automotive manufacturing, electronic equipment, medical devices, etc., bringing tremendous changes to industrial production. Through CNC technology, not only can production efficiency be improved and costs reduced, but more creative and design oriented products can also be created.
Overall, CNC technology is an innovative and promising technology that will continue to drive industrial development and progress, creating a better life for humanity.
1. Automation core: The core of CNC is to replace traditional manual operations with computer programs, achieve automation of the machining process, and significantly reduce human errors.
2. Digital instruction driven: All operations rely on standardized digital code (the most common being G-code and M-code), and once the program is written, it can be reused for mass production to ensure product consistency.
3. High precision and efficiency: The precise control of computers can achieve machining accuracy at the micrometer level or even higher, and the machining speed and stability far exceed manual labor, making it suitable for the manufacturing of complex shaped parts.
4. Wide applicability: CNC technology has penetrated into various fields of mechanical manufacturing, and common CNC equipment includes CNC lathes, CNC milling machines, machining centers, laser cutting machines, 3D printers, etc.
Working Principle
cnc machines use CAD software to design 2D/3D layout files, and use CAM software to create G-code. Then, an automatic computer controller is used to start processing, read the G-code, start programming, and drive the spindle to move along the tool path, automatically completing the work. In modern computer numerical control systems, the design of workpieces highly relies on software such as computer-aided design (CAD) and computer-aided manufacturing (CAM). Computer aided manufacturing software analyzes design models and calculates motion instructions during the machining process. The motion instructions and other auxiliary instructions required during the machining process are converted into a format that can be read by the CNC system through a post-processing unit. The generated file is loaded onto a computer numerical control machine for part processing. After importing program instructions into the memory of the computer numerical control system, the computer compiles and calculates them, and transmits the information to the driver through the displacement control system to drive the motor to cut the designed parts.

User Guide
The nine basic steps for operating machines in a workshop.
Step 1. Edit and input files.
Before processing, you should analyze and compile the files of the project. If the file is complex, do not program it on the machine tool, but use programming tools or computers to program it, and then backup it to the control system through a USB flash drive or communication interface. This can avoid increasing the auxiliary processing time when using the machine tool.
2. Power on.
Usually, check the air pressure and fuel tank first to ensure they are within the normal range of values. Then connect the main power supply to enable the machine tool to be powered on. Start the control system with the button and power on the machine tool at the same time. The information is displayed on the CRT of the control system. At the same time, check the connection status of auxiliary equipment such as hydraulic, pneumatic, and input shafts.
3. Entity reference points.
Establish motion benchmarks for each coordinate before processing. For machine tools with control systems, this step should be performed first.
4. Import and call programming.
According to the program medium (USB flash drive), it can be input through a computer, programming tool, or serial communication. If it is a simple program, it can be directly input on the control panel, or it can be input segment by segment and processed in MDI mode. Before processing, it is also necessary to input the origin, tool parameters, offset, and various compensation values in the processing program.
5. Program editing.
If it is necessary to modify the input program, the working mode selection switch should be placed in the editing position. Use the edit keys to add, delete, and modify.6. 6.Program inspection and debugging.
Firstly, lock the machine tool and only run the system. This step is to check the program, and if there are any errors, they need to be re edited.
7. Project installation and alignment.
Install and align the lower spare parts to be processed and establish benchmarks. This method uses manual incremental motion, continuous motion, or handwheel to move the machine tool. Align the starting point with the beginning of the program and set the tool benchmark.
8. Coordinate axis for starting continuous processing.
Continuous processing generally uses programs stored in memory for processing. The feed rate of computer numerical control machining can be adjusted through the feed rate override switch. During machining, the feed hold button can be pressed to pause the feed motion, observe the machining situation, or perform manual measurement. Press the cycle start button again to resume processing. To ensure the program is correct, you should check it again before processing.
During the processing, you can use a pencil instead of a tool to draw the outline of a planar curve project on paper. If the system has a tool path, the simulation function can be used to check the correctness of the program.
9. Close.
After processing and before turning off the power, pay attention to checking the status of the machine tool and the location of spare parts.
First, turn off the device power, then turn off the system power, and finally turn off the main power.
Buying Guide
There are various types of CNC machine tools in the world, as well as various machine tool brands and manufacturers. This phenomenon has both advantages and disadvantages for buyers. The advantage is that customers have more choices and can purchase more useful machine tools from distributors. Unfortunately, after watching too much, they don't know which one is the best to buy. As the saying goes, it's not good to be cheap, it's not good to be cheap.
So, what should be considered when making a purchase?
1. Meet your requirements
Computer controlled machine tools cannot complete all tasks. In order to professionally process different materials, manufacturers classify them into multiple types. If you buy a machining center to process doors and windows, or an all-in-one machine to process small output products, it will be overused and the machine's functions will not be fully utilized. This will not only waste a lot of money, but also have a negative impact. So before making a purchase, it is important to communicate clearly with the salesperson to let them know your purpose, production requirements, precision requirements, as well as the size, material, and processing effect of the processing materials.
2. Type and model selection
If you need to process high-end doors and windows, you should purchase a door and window workstation. If you also have curtain wall business, you can choose a machining center. If your output is not high, we will recommend you to choose a drilling and milling machine, and determine the model of the drilling and milling machine based on the size of the milling project. If used for cutting metal, we have options for single head, double head, and multiple angles. If you want to process long and thick materials, we will provide a customized product plan. Therefore, you should purchase professional machines according to your business plan and project.
3. Provide solutions (customized machines)
Before purchasing, in order to ensure that the machine you have chosen meets your requirements, you must have the sales manager customize a solution based on your product. The advantage is that you can see the actual processing effect and the time it takes.
4. Sign the contract
After completing the above three points, it is necessary to sign the procurement contract. A complete contract is the best guarantee for safeguarding the legitimate rights and interests of individuals. Firstly, the contract should clearly indicate the purchased model, configuration, price, delivery time and method, training method, warranty terms, and specific payment method. After the contract is signed, the corresponding deposit is generally paid according to the contract agreement. We must comply with the content agreement of the signed contract to avoid unnecessary conflicts with the seller in the future.
5. Factory inspection
In order to ensure that the purchased machine can achieve the processing effect required by the customer, we will debug the machine according to the customer's production requirements after the machine is produced, and provide machine testing and processing videos. After the customer's acceptance, we will arrange for shipment.
6. Delivery and Training
After the machine is shipped on time, the supplier's technicians will assist you in opening the packaging box and conducting an inspection in your workshop (if you have already paid for the door-to-door service, the technicians will arrive at your workshop before arrival). During transportation, the appearance of the machine should be carefully inspected for any damage. If good, check the parts and accessories according to the packing list and contract terms. Next, let the technicians set up the machine (including hardware assembly, software installation, and debugging). After setting up, conduct sample testing on the machine. If the completed project is good, the delivery inspection will be completed. Employees are required to have a strong sense of safety responsibility and must possess proficient machine tool operation skills before starting work. During the training process, you should be proficient in selecting different cutting speeds and using different drill bits and tools for different materials. This requires skills and experience. Good mastery is more conducive to extending the service life of machines and tools.
7. Service and Support
When you encounter hardware and software problems during use, you need to contact the dealer, communicate clearly, make the service personnel aware of the problem and start troubleshooting. Do not handle it yourself, which may lead to accidents when you are not familiar with the machine. The manufacturer may refuse to continue providing warranty services for the device. In terms of after-sales service, we can require CNC machine tool manufacturers to strictly comply with the contract agreement. If you encounter intentional procrastination or poor attitude, you can file a complaint with the person in charge.
