Embodiment Construction

[0014] The specific steps of a chamfering process method for a ceramic substrate welding structural part are as follows:

[0015] The first step is to install the plane roughing

[0016] According to the actual size of the ceramic substrate, which is 20mm×30mm, rough machining is carried out on the installation plane to be processed on the structural part, so that the size around the installation plane is 0.05mm larger than that of the ceramic substrate.

[0017] The second step is to install the plane chamfering process

[0018] According to the shape of the actual requirements of the installation plane, the R2 rod milling cutter is selected to process the installation plane. Since the corners processed by the rod milling cutter are rounded, which do not meet the installation requirements of the ceramic substrate, when processing to the corner position of the installation plane When processing, it is processed to the outside of the installation plane to form a semicircular w...

Abstract

The invention discloses a chamfering process method for a ceramic substrate assembling and welding structural member. According to the method, firstly, rough machining is performed on a mounting plane, so that s size around the mounting plane is larger allowance than a ceramic substrate; then chamfering processing is performed on the mounting plane, when an angular position of the mounting plane is processed, the outside of the mounting plane is processed to form a semi-circular waist groove that protrudes outward; and finally finish machining is performed on the mounting plane, machining burrs of the mounting plane are cleaned, and machining is completed. The method can make the product quality greatly improve, chamfering treatment is performed on the ceramic substrate assembling and welding structural member, and so, secondary right-angle processing of an installation position of the structural member is avoided, and the problem of fragmentation of the ceramic substrate is solved.

Description

technical field [0001] The invention relates to a chamfering process method of a structural part, in particular to a chamfering process method of a ceramic substrate welding structural part. Background technique [0002] Structural parts are the substrate for assembly and welding of ceramic substrate circuit boards. The shape of ceramic substrates needs to be consistent with the installation position of structural parts to ensure reliable assembly and welding of circuit boards. The four sides of the ceramic substrate are designed to be right angles, and the four corners of the corresponding installation parts of the structural parts must be right angles. The method of machining the right angles of the inner cavity of the structural parts is to use the right angle electrode for electric discharge machining through the EDM machine tool. This method requires a special machine tool. processing, and the bottom surface of the inner cavity will leave black electro-corrosion spots...
