CNC machining is exponentially controlled machining, a method of using digital information to control mechanical movement and machining processes. Traditional machining is done with manually operated ordinary machine tools. During machining, the metal is manually cut with a mechanical tool, and the tool is used to measure the accuracy of the product using a calibrator. However, traditional manual processing is far from meeting the production requirements.

Features of CNC machining

The CNC machining quality is stable, the surface texture of the finished product is clear, the metal texture is firm, smooth and flat, without scratches and corners, and the heat dissipation coefficient of the raw materials is small. It doesn't change with precision machining. Manufacturers can adjust specific processes to improve their thermal performance. For example, processes such as oxidation, stretching, cooking, sandblasting, etc. can all be carried out under CNC operation.

CNC processing adopts imported equipment; the products processed by automatic lathe parts have accurate threads, anti-skid, tolerances up to 0.01mm, smooth appearance, no burrs, and no sticking. CNC machining is carried out in strict accordance with the dimensional specifications of drawings and samples, and the tolerance accuracy is as high as 0.01 mm. Each batch of products can only be delivered to customers after three precise inspections, and the defective product rate is strictly controlled within 1/1000.

The automatic control system of the CNC machining center can usually control the CNC lathe to complete the automatic start-stop, reversing and shifting of the spindle bearing according to the digital program flow instructions. It can intelligently control the feed speed, direction and production and processing distance, select the size of the CNC blade according to the production and processing of the CNC blade, and change the cutting amount and walking trajectory to complete various auxiliary actions required for production and processing.

The reason why CNC machining is widely used

CNC machining is to use the automatic control system to install digital program flow instructions to control the automatic start-stop, reversing and speed change of the bearing of the CNC machine tool. CNC inserts can be selected, which can change the cutting amount and walking path of the CNC inserts, and complete various auxiliary actions required for lifelong machining. CNC machining can greatly reduce the total number of tooling, producing parts with complex processing methods, only need to change the process flow. CNC machining is relatively stable and will not cause machining deviations.

CNC machining can produce complex aluminum parts and even machined parts. And can produce a variety of varieties, high production efficiency, save labor costs, and can achieve a variety of mass production. The CNC machining control system can use control codes or other symbolic instruction rules to logically process the program, use the computer to decode the program, and then move the machine tool and machine parts. After the tool is cut, the blank is processed into semi-finished products, etc. CNC cutting is not only a more reasonable processing method, but also a common process for precision processing of aluminum alloys. Choose end mills with multi-directional cutting capabilities, helical interpolation and contour cutting interpolation, and choose fewer tools to machine a small number of holes.

In the CNC machining process, we must master the processing skills of craft paint. Select a reasonable cutting amount, and the personnel select the cutting speed according to the requirements of the processing material, hardness, cutting conditions, material type, and cutting depth. These conditions are necessary to reduce machine wear. Choosing the right tool Generally speaking, when using rough turning, it is best to choose a high-strength tool to better meet the requirements of rough turning. The selection of reasonable fixture parts should fully meet the needs of the machine and reduce unnecessary positioning errors, so that special fixtures can be selected to accommodate items. Acknowledging a reasonable process. Minimize the processing stroke and reduce machine wear.
