Can not meet the increasing demand for machining of industrial ceramics

Because the nature of the ceramic product is high hardness, toughness, and brittleness, and it is particularly susceptible to crushing due to pinching, it cannot be directly processed by ordinary metal processing methods. The quartz ceramic workpiece shown in the figure is a small batch of workpieces encountered in our scientific research and development process. In order to process this product, we carefully analyzed and researched the ceramic workpieces according to the actual conditions of our production workshop. The following formulas were made for the machining process. We first positioned both ends of the boring 92 and the inner bore, roughing the outer circle to the two end faces. Intestines Because the round blanks of the ceramic workpieces have a large margin and the surface quality is poor, the outer circle of the blanks is processed first to prepare for subsequent processing. In addition, according to the requirements of the drawings, there are shaft requirements for the inner hole of the workpiece and the outer circle of the workpiece. The outer circle of the workpiece is processed first to prepare the inner hole for the next process. The outer circle of the workpiece is positioned so that the inner surface of the hole will be flat and the depth of the inner hole will meet the drawing requirements. The hole in the hole must meet the requirements of the drawing and is no longer processed. The inner hole must be aligned with the counterbored hole to finish the outer diameter. The hole must have the same coaxiality as the outer circle. The hole location should be better. However, the wall thickness of the bore and the taper must be small. The strength of ceramic products is more secure with the holes, and holes and holes must be machined in one station to ensure the coaxiality. Positioning with 92 holes can also meet the technical requirements of drawings. According to the situation of the workshop, the cylindrical grinder is selected, and the appropriate diamond grinding wheel is used for the outer circle machining. Because the quartz ceramic workpiece is easily broken by the impact of the clamping pressure, it cannot be directly clamped on the machine tool. The tooling is designed according to the processing technology, such as the height and parallelism of the center. With a motor, the belt is used to connect the motor to the grinding tool, so that a temporary grinding machine in the country can be processed.
