Parts made by precision machining have high requirements, so the production process also needs to be very strict. Otherwise, the products can not meet the use requirements, which will affect the production safety. Therefore, these requirements need to be met in the process of precision machining to ensure the quality.
1. The selection of equipment should be reasonable. Rough machining of mechanical parts mainly cuts off most of the machining allowance, and does not need high-precision machining. Therefore, rough machining should have more power and high-precision machine tools, and adhere to the use of a relatively high-precision machine to complete the process. Rough and finish machining in different machines, can give full play to the equipment capacity, can extend its service life of precision machine tools.
2. The machining of coarse and fine mechanical parts should be separated to ensure the machining accuracy of precision parts. Because when the rough mechanical parts are processed, the cutting force, clamping force, heat and machining surface of mechanical parts have obvious work hardening phenomenon. If the rough and rough mechanical parts are processed continuously, the precision of the parts will lose quickly due to the stress redistribution. For some high precision parts of mechanical parts processing. After rough machining and finish machining, low temperature annealing should be arranged or aged to eliminate internal stress.
3. In the process route of high precision mechanical parts, it is necessary to arrange the heat treatment process. The location arrangement is as follows: heat treatment process, improve its cutting performance of metal, such as annealing, normalizing, tempering, generally arranged in mechanical parts processing. Eliminate internal stresses such as aging treatment, adjustment treatment, as shown in the general layout, after rough machining but after completion. In order to improve the mechanical properties of components, such as carburizing, quenching and tempering, are generally arranged in the mechanical parts processing. If the deformation is large after heat treatment, the final processing should be arranged.
The above are the conditions that the precision mechanical process needs to meet. Dalian HAMP can produce qualified products in strict accordance with the technical standards. Welcome to consult us.
