Abstract

The invention belongs to the technical field of spaceflight servo systems, and particularly relates to a non-waterline cutting method and a non-waterline cutting device. By the non-waterline cutting method and the non-waterline cutting device, requirements on linear cutting machining precision and cutting speed of an end surface of a filter element are met, and the cutting quality is high under the condition that the filter element is not polluted when cut off. The non-waterline cutting method comprises the following steps of (1) preparing a setting process; (2) erecting up a core tube 5 of which the length is smaller than that of the filter element in the filter element 4, and placing the core tube 5 and a dovetail groove supporting seat 3 of which the boundary dimension is matched with that of the filter element 4 in a base 7 together; (3) covering the base 7 by using an upper cover plate 6 and fixing the filter element 4 by manually fastening a butterfly nut 2; and (4) changing the dovetail groove supporting seat when filter elements with different specifications are machined and remaining rest positioning datum reference pieces in the device. The dovetail supporting seat is a V-shaped support, and the filter element can be automatically aligned after being placed in the dovetail supporting seat.

Description

technical field [0001] The invention belongs to the technical field of aerospace servo systems, and in particular relates to a waterless wire cutting method and device. Background technique [0002] The filter element is the core part of the servo product filter, the structure is as follows figure 1 . The filter element is composed of a filter mesh and a liner mesh folded to form corrugations. After welding at the folded butt joint, the end surface of the filter element is not flat due to folding deformation. It is necessary to process both ends of the filter element. The flatness of the end surface directly affects the adhesion between the filter element and the end cover. quality. Since the filter element is composed of non-dense materials, if the mechanical cutting method is used, the processing deformation is uncontrollable, so only special processing methods are used, and the wire cutting method of the EDM process has no cutting force. And because the filter material...
