The embodiment of the invention provides a dielectric filter processing method and device. Machining and punching in the traditional filter manufacturing process are replaced by a laser punching mode.The phenomenon that cracks are generated on the surface of a product in a machining method is avoided. The conicity after laser drilling can be effectively reduced by adopting a rotary cutting method, the shape precision of laser drilling is improved, the size of the filter is closer to a design value, and the performance is more idealized. Meanwhile, the position, depth, taper and flatness of the hole and the thickness of the metal coating are verified through the 3D contour image in the manufacturing process, and the performance of the product is guaranteed. The problem that in the prior art, the filter machining precision is low, so that when a small filter is manufactured, the structural size precision cannot meet the requirement, and consequently frequency coupling of the filter is poor is solved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of filters, and in particular to a method and device for processing a dielectric filter. Background technique [0002] It is very common to make a small hole in the component. However, if it is required to drill a large number of small holes with a diameter of 0.1 mm to several microns on hard materials, such as cemented carbide and ceramic media, it may not be easy to do it with ordinary machining tools. Even if it can be done, the processing cost It will also be high. Existing mechanical processing technology makes micro-holes on materials by using high-speed rotating small drills with tens of thousands or hundreds of thousands of revolutions per minute. Generally, this method can only process small holes with a diameter greater than 0.25 mm. In today's industrial production, it is often required to process holes with a diameter smaller than this. For example, in the production...
