Embodiment Construction

[0027] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] For the grooving process in the present invention, the machine tool used for abrasive water jet cutting is the abrasive water jet machine tool produced by Nanjing Dadi Waterjet Co., Ltd., and the performance parameters of the abrasive water jet machine tool are shown in Table 1.

[0029] In order to intuitively reflect the advantages of abrasive water jet grooving, the grinding wheel and abrasive water jet are respectively used for grooving on flat alumina ceramic workpieces.

[0030] Among them, the grinding wheel grooving parameters are: feed speed V 1 =5-10mm / min, cutting depth h=2.5-4.5mm, flange thickness b=2-4mm;

[0031] The processing parameters of abrasive water jet cutting are: feed speed V 2 =40-60mm / min, pressure P=240-300Mpa,...

Abstract

The invention provides an abrasive water jet grooving-diamond wheel grinding composite ceramic machining method. The method comprises the following steps that S1, grooving machining is carried out ona flat-plate ceramic workpiece by adopting an abrasive water jet machine tool according to machining requirements to form a parallel flange; and S2, the parallel flanges formed in the step S1 is ground by adopting a diamond grinding wheel until the machining needs are met, wherein abrasive water jet cutting machining mainly consumes water and abrasive particles, no tool is worn in the machining process, the used abrasive is low in cost, and the machining cost can be greatly reduced. In conclusion, the crack propagation effect is utilized so that high-removal rate machining of hard brittle materials such as ceramics can be realized on the premise of higher feeding speed and no tool abrasion.

Description

technical field [0001] The invention belongs to the technical field of rough processing of hard and brittle materials, in particular to an abrasive water jet grooving-diamond grinding wheel push-grinding composite processing technology applied to engineering ceramics. Background technique [0002] Engineering ceramic materials, such as silicon carbide, silicon nitride, alumina, etc., have excellent properties such as high hardness, corrosion resistance, and wear resistance, and are widely used in engineering fields. However, due to the high hardness of ceramic materials, it is more difficult to process, and its own brittle characteristics will cause processing damage such as cracks and chipping during processing. Therefore, high-efficiency and low-damage processing of ceramic materials has always been the industry's priority A big problem. In the existing technology, there are traditional mechanical processing methods such as grinding, turning, and milling, as well as speci...
