CNC machining means that a computer-controlled CNC lathe completes the production and processing of parts and components. The internal structure of the CNC lathe is like an intelligent robot. It must be used in conjunction with the application and follow all instructions. The specific meaning of CNC processing is to remove the excess parts of the raw materials to make them have the appropriate appearance, such as round, rectangular, etc. In the traditional method, these machines and equipment are actually operated by the operators of the experts who actually operate these machines and equipment.
Most of the work must be precisely produced and processed, and the actual operation staff should have sufficient professional capabilities to complete precision machining. In the CNC machining center, the role of the operator is minimized. The actual operating staff must only enter the instruction application program on the computer, load the required tools into the machine equipment, and other tasks are automatically completed by the computer system. The computer instructs the CNC processing center to perform various actual production and processing operations according to the instruction program fed by the operator. CNC machining has the advantages of high speed, high efficiency, high precision and high reliability.
How many types of CNC machining?
1. CNC machining CNC tools are divided into five categories according to commonly used materials. According to commonly used materials, it is divided into high-speed steel CNC tools, cemented carbide tools, ceramic tools, cubic boron nitride (CBN) CNC tools and diamond tools.
2. The CNC processing is divided into four categories according to the structure. According to the structure, it is divided into overall CNC tools, insert CNC tools, machine clamp CNC tools and composite CNC tools.
3. CNC processing is divided into two categories according to whether it is standardized. According to standardization, it is divided into standard CNC tools and non-standard CNC tools.
The price of CNC processing is about a few yuan per piece, the cheap one is one or two yuan, and the expensive one is dozens of yuan. The price of CNC processing is affected by many aspects, such as brand, type, specification and model, and market. Before choosing to purchase, it is necessary to master and compare in many aspects.
