You must not know the process of KOVAR parts processing, then let me know about it!

u200b The production process of KOVAR parts processing has a great relationship with the process, including the process environment elements and the optimization configuration elements of the process route. The process route process needs to be formulated by an experienced person. The following is a brief explanation of the process process .u200b Formulation of the process route process: First, we should carefully analyze the geometric structure of the parts, the core parts of the accuracy index, the accuracy requirements, material characteristics, heat treatment requirements and performance requirements, etc. Many process links such as stress relief process measures are reasonably configured. During the production organization, the process is strictly implemented. During the process, strict inspection is performed. For general precision parts, the process route is: rough machining-aging-semi-precision Machining-finishing can be done. Facing the processing of precision mechanical parts, such a processing route is obviously not enough. The processing route must be lengthened, and aging treatment must be properly interspersed, and super-finishing procedures are configured to ensure the processing requirements. The usual process flow is: primary roughing-primary thermal aging-secondary roughing-secondary thermal aging (or vibration aging)-semi-finishing-vibration aging is enough-finishing-natural aging (or low temperature stable treatment)-precision Processing. Among them, the heat treatment requirements of precision parts should be arranged according to the different requirements of the overall hardness, partial hardness and surface hardness of the parts. The stable processing of the precision mechanical parts processing accuracy is also very critical and complex, simple one or two. These methods can no longer meet the requirements, and usually adopt a variety of methods according to needs, such as stress annealing, low temperature stabilization, vibration aging, natural aging, and even cold treatment to achieve the accuracy and stability requirements of precision parts. In order to ensure the machining accuracy, roughing and finishing are best performed separately. Because of the large amount of cutting during rough machining, the workpiece is subjected to large cutting force, clamping force, heat generation, and the machined surface has a significant work hardening phenomenon, and there is a large internal stress inside the workpiece. If rough and rough machining Continuously, the precision of the parts after finishing will be quickly lost due to the redistribution of stress. For some parts that require high machining accuracy. After rough machining and before finishing, low temperature annealing or aging treatment procedures should also be arranged to eliminate internal stress.
