What problems should be paid attention to in aluminum alloy processing orders?

Aluminum alloy processing orders according to the number of requirements, can be divided into batch processing and bulk processing, but no matter what kind of processing service type, some common problems should be avoided. First, in the CNC processing link, it is very important to program and process according to the requirements of customers' drawings. Generally speaking, if the direction is wrong, the work behind is futile. Secondly, the detection link in the processing process, the number is different, the detection requirements are not the same, parts processing, usually requires that parts must be fully checked; Batch processing, the first test, mass production sampling is not omitted. But some people may think that batch processing orders, if it is completely programmed in accordance with the drawings and carried out the first test, there is no need to test the back, but, Shenzhen Novo Wisdom xiaobian tell you that this idea is very wrong. Second, most of the aluminum processing orders are post-processing requirements, common is sandblasting and oxidation. Sandblasting, the general customer will be given sandblasting model, and then pay attention to the depth of the knife grain problem in the processing of aluminum alloy factory, because the sandblasting model is sometimes determined by the depth of the knife grain. If oxidation, special attention should be paid to the color problem, and carefully compare with the customer to the color plate and color number, there is a visible color difference, it is necessary to rework, especially on the premise of the customer has clear requirements for color.

What are the environmental and equipment requirements for precision machined hardware?

What are the environmental and equipment requirements for precision machined hardware?

At present precision hardware processing workpiece accuracy has reached the micron level, it not only needs to have precision processing equipment, cutting tools, precision measuring instruments and high technical level of workers, good processing environment is also the main factor to ensure precision hardware processing accuracy. If the dust is too much, it will scratch the surface of the workpiece and affect its surface quality, so we need to strengthen the purification in the workshop. In the process of precision machining, the process system is affected by internal heat sources such as cutting heat and friction heat, and at the same time exchanges heat with the external environment. So the external environment temperature becomes an important factor affecting the machining accuracy. Due to the different heat source intensity and distribution location, the temperature rise of each part of the machine tool is different in the processing process, and the thermal expansion coefficient of different materials is different, resulting in different deformation of the lathe bed, spindle, grating ruler and tool rest and other components, thus destroying the original geometric accuracy of the machine tool. The temperature difference of each component of the machine tool can be reduced by placing the machining equipment in a stable ambient temperature, thus reducing the difference of deformation. To sum up, too much change in ambient temperature has become the main source of errors in the processing of precision hardware parts. Too high temperature will cause thermal deformation of machine tools, cutting tools and measuring devices, resulting in processing errors and measuring errors. In the cutting of precision parts, vibration has a great influence on machining accuracy and surface roughness. Vibration is mainly caused by natural external force, traffic vibration, vibration when people walk and vibration caused by machine tools and equipment. Based on the above reasons, when we are processing precision hardware parts, the working environment should be purified, anti-vibration and constant temperature.
