With the rapid development of modern mechanical processing and the rapid development of mechanical processing technology, many advanced mechanical processing technology methods have emerged slowly, such as precision ultra-precision processing technology. Precision and ultra-precision machining is an important part of modern mechanical manufacturing technology, and one of the important indicators to measure the level of a country's high-tech manufacturing industry. Precision machinery and equipment manufacturing requires not only high dimensional and shape accuracy, but also high surface quality. According to the current market development, there is a great demand for this kind of manufacturing technology.
First of all, many parts and components themselves have certain deficiencies. For example, some parts can not meet the requirements in appearance, and some parts have certain limitations in scope of application. In a word, these parts themselves have certain defects. In the process of application, they will bring some achievements and troubles to their industrial consumption. Fine machine processed parts can be a great restraint of these achievements, so as to discover the common value of the parts themselves. Many medium-sized parts also need to be assembled, so precision machine parts manufacturers will stop reprocessing in response to this demand. After processing various parts, we can lose more suitable parts for ourselves. Therefore, in order to make these goods better serve us, precision machine processing to. Life and consumption have little significance.
Not all materials can be processed precisely. Some materials whose hardness is too high to exceed the hardness of the machined parts may break down the machined parts. Therefore, these materials are not suitable for precision machining unless they are made of special materials, Changshu Precision Machining or laser cutting.
1. Multi-axis control linkage: Generally, three-axis linkage is used more, but through some adjustments, four-axis, five-axis, seven-axis or even more linkage axis processing centers can be achieved.
2. Parallel machine tools: The functions of common machining centers are relatively fixed, which can combine the machining centers with turning centers, or vertical and horizontal machining centers, which can increase the processing range and processing capacity of the machining centers.
3. Tool damage early warning: Using some technical detection means, we can find out the wear and tear of the tool in time, and give an alarm, so that we can replace the tool in time to ensure the processing quality of the parts.
4. Tool life management: Unified management of multiple simultaneous working tools and multiple blades on the same tool can be carried out to improve production efficiency.
5. Overload power-off protection of machine tools: According to the limit load level set according to the production process load, when the load reaches the set value, the machine tools can realize automatic power-off to protect the machine tools.
Deformation caused by workpiece clamping: When machining workpiece clamping, the correct clamping point should be selected, and then the appropriate clamping force should be selected according to the position of the clamping point. Therefore, in order to make the clamping point and the support point consistent, let the clamping force act on the support, the clamping point should be as close as possible to the processing surface, and then choose the position where the force is not easy to cause clamping deformation. When there are clamping forces acting in several directions on the workpiece, the sequence of clamping forces should be considered. For the clamping force in contact between the workpiece and the support, it should play a first role and not be very large, but for the main clamping force in balancing the cutting force, it should play a second role. The contact area between workpiece and fixture should be enlarged and the axial clamping force should be applied in the processing of mechanical parts. Increasing the rigidity of mechanical parts is a better way to solve clamping deformation, but because of the shape and structure characteristics of thin-walled parts, it has relatively low rigidity. In this way, under the action of clamping force, deformation will occur.
The material and structure of the workpiece will affect the deformation of the workpiece: the deformation is proportional to the complexity of the shape, the ratio of length to width and the thickness of the wall, and to the rigidity and stability of the material. Therefore, the influence of these factors on workpiece deformation is minimized in the design of parts.
