Research On The Key Technology Of Manufacturing With Elastic Thin Plate Flotation Cushion

With the development of precision and ultra precision technology, the requirement of pro cessing machinery and testing technology increase, floating cushion the machining accuracy and therefore put forward higher requirements. For elastic thin plate floating cushion manufacturing technology research is not enough in place, especially the key parts of the manufacturing process, so it is of the key parts of the elastic thin plate floating cushion manufacturing technology is a difficult problem in the field of floating cushion manufacturing.This topic mainly for elastic thin plate floating cushion to research the key technology, realization of slider and elastic thin plate is good connection. This article mainly adopted three scheme namely metal bonding, under the condition of the vacuum welding, vacuum brazing of elastic thin plate and the feasibility of the sliding block connected by trying, results show that the bonding metal and the welding does not meet the requirements under the condition of vacuum, and adopts the vacuum brazing welding floating cushion, can achieve good elastic thin plate and the slide block connections. But there are many factors affecting the quality of welding joint, may lead to brazing seam, the defect caused by the mechanical properties of welded joint is reduced, by analyzing the causes of weld defects, and experiments on the brazing of main process parameters (vacuum, heating rate, stability time, brazing temperature and holding time and cooling mode) selection of suitable, and the microstructure of welding joint of metallographic analysis, the analysis results show that uniform braze welding head group, no obvious flaws, satisfied requirements of welding joint, proved by vacuum brazing of elastic thin plate and the slide block can be accomplished by a good connection.At the same time, in order to realize the elastic thin plate floating cushion pneumatic polishing processing, adopted a can make floating cushion belt and the rotation of the sealing device, can make the floating elastic thin plate mat on the grinding and polishing experiment equipment automatic inflatable grinding and polishing. Affect the elastic thin plate in the process of grinding and polishing floating pad surface quality factor are many, inductive, mainly the following parameters:the material of grinding disc and speed, and type of abrasive particle size, concentration of grinding fluid, and polishing pressure. For each parameter using the best optimum combination, under the condition of optimum combination parameters, grinding and polishing of the surface of the elastic thin plate floating cushion level off is smooth, no scratches, and reach the mirror effect, and proved through the study of this article can realize flexible sheet lapping air floating cushion of air.
