Dalian precision machining is an important manufacturing technology that plays an important role in the development of various industries. With the continuous progress of science and technology and the increasing demand for quality, precision machining will continue to develop and play a greater role in the future. At the same time, we also need to strengthen technical training and learning, cultivate more precision machining talents, to meet the needs of society and development.

The commonly used equipment for precision machining includes CNC machine tools, lathes, milling machines, drilling machines, grinding machines, etc. CNC machine tools are the main processing equipment for modern precision machining, including CNC machining centers, CNC lathes, CNC milling machines, etc. They can achieve precise control of machining process parameters through computer control systems, improving machining accuracy and efficiency. Lathe is mainly used for processing rotational symmetric parts, milling machine is mainly used for processing special shaped parts such as planes, contours, and cavities, and drilling machine is mainly used for processing holes, etc. Grinding machine is a high-precision processing equipment commonly used in precision mechanical processing for precision grinding and grinding of parts to improve surface quality.

What are the common correction and debugging techniques in precision machining in Dalian?

1. Preparation before machining: Before precision machining, careful preparation work must be carried out, including reviewing design drawings, confirming machining processes, selecting suitable machine tools and cutting tools, etc. Only on the basis of these preparations can we better carry out correction operations.

2. Choose the appropriate fixture: The selection of fixtures is crucial for ensuring the positional accuracy and machining quality of the workpiece. When selecting fixtures, factors such as the magnitude of clamping force, the position and number of clamping points should be considered, and reasonable selection and design should be made based on the shape of the workpiece and processing requirements.

3. Correction of machine tool errors: Machine tool errors are one of the important factors affecting machining accuracy. By compensating for positioning errors of machine tools, adjusting machine coordinate systems, and adjusting machine tools, machine tool errors can be effectively reduced and machining accuracy can be improved.

4. Control cutting force: Cutting force is another important factor that affects machining accuracy. During the machining process, the cutting speed and depth should be reasonably selected, and appropriate cooling and cutting fluids should be used to reduce the influence of cutting force, prevent workpiece deformation and tool wear.

5. Control tool wear: Tool wear is one of the important reasons for machining errors. By means of reasonable tool selection, tool grinding, and tool replacement, tool wear can be effectively reduced to ensure machining quality.

6. Control machining temperature: Temperature changes during the machining process can cause deformation of the workpiece and tool, thereby affecting machining accuracy. Therefore, appropriate cooling measures should be taken, such as using coolant and cutting fluid, and reasonable cooling and heating treatment should be carried out on the workpiece to reduce the impact of temperature on machining accuracy.

Precision machining refers to the process of processing raw materials into components with high precision, high surface quality, and complex shapes through a series of cutting, forming, and machining processes on a machine tool. Compared with traditional machining methods, it has higher machining accuracy and better surface quality. Precision machining can be divided into two types: CNC machining and non CNC machining.

In order to ensure the quality of precision machining, a series of quality control methods need to be adopted. Regular maintenance and upkeep of processing equipment is required to ensure its normal operation and stable accuracy. Secondly, conduct a pre processing inspection to ensure that the quality and dimensions of the materials meet the requirements. During the machining process, it is necessary to continuously monitor and control machining parameters, including cutting speed, feed rate, tool wear, etc. Quality inspection after processing, including dimension measurement, surface quality inspection, etc.
