Problems solved by technology
However, due to structural constraints, the inner walls at both ends of the stator frame can only be machined with grinding wheels with a diameter of 2 mm, which has low processing efficiency and requires high precision of the grinding machine.
In addition, since the inner walls at both ends of the stator frame are blind holes, the final axial end surface cannot be processed during internal grinding, and the final axial depth must be guaranteed by finishing machining, which increases the time for secondary alignment and further Reduced processing efficiency

Description
technical field [0001] The invention relates to the technical field of high-efficiency numerical control machining of a gyroscope motor stator, in particular to a high-precision glass-ceramic motor stator turning and grinding compound processing technology and special tooling. Background technique [0002] The core part of the high-precision liquid floating gyroscope dynamic pressure motor is made of hard and brittle material machinable ceramics. This part is composed of a variety of parts and has a complex structure. The whole is an annular thin-walled structure, and the radial wall thickness is the smallest. Only 0.2mm, it is very easy to crack and cause parts to be scrapped. figure 1 Shown is a schematic diagram of the three-dimensional structure of the motor stator. The stator is composed of a stator cover 1, a stator frame 2, and a coil 3 wound on the stator frame. The materials of the stator frame and the stator cover are both glass ceramics. [0003] Since the stator...
