Problems solved by technology

However, the abrasive grain optimization arrangement grinding wheel proposed by scholars is mainly aimed at large-grain abrasives, and its manufacturing method is likely to cause a decrease in the distribution density of the abrasive grains of the grinding wheel, resulting in an increase in the surface roughness of the workpiece.

Embodiment Construction

[0023] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0024] See figure 1 , figure 2 with image 3 , Ordered structure electroplating grinding wheel includes: grinding wheel base 3 and abrasive grain layer 8 with orderly arranged abrasive grains. The material of the grinding wheel base 3 is high-strength aluminum alloy with a diameter of 100-200 mm and a thickness of 12-20 mm. There is a spiral groove 5 with a fine structure on the outer circumferential working surface 4 of the grinding wheel base. The spiral groove 5 has a width of 50-80 μm, a depth of 60-100 μm, a pitch of 200-300 μm, and the spiral groove is filled with epoxy Resin 6. The material of the abrasive particles 7 is cubic boron nitride or diamond, and is fixed on the grinding wheel base 3 through a nickel-cobalt alloy coating.

[0025] When processing the grinding wheel base body, the two end faces of the grinding wheel base body 3 are firstly ...

Abstract

The invention discloses a manufacturing method of an electroplated grinding wheel of an ordered structure. The method includes: adopting a pulse laser beam to process a fine spiral groove with the pitch of hundreds of micrometers and the notch size of dozens of micrometers in the working surface of the outer annulus of a grinding wheel base body made of metal, filling the groove with epoxy resin, and enabling the metal and the epoxy resin on the working surface of the outer annulus of the grinding wheel base body to be in spiral regularly-spaced layout; then electroplating the working surface of the outer annulus of the grinding wheel base body with abrasive grains by adopting an electroplating method. Since the groove is filled with the non-conductive epoxy resin, the region cannot be electroplated with the abrasive grains. By the steps, the electroplated grinding wheel with the abrasive grain layer and the epoxy resin being in spiral regularly-spaced layout can be obtained. The manufactured electroplated grinding wheel of the ordered structure is in favor of solving the problems that the grinding wheel is blocked easily during grinding and grinding fluid cannot enter the grinding region easily, workpieces can be prevented from being burnt, and the grinding quality is improved.

Description

Technical field [0001] The invention relates to a manufacturing method of a grinding wheel, in particular to a manufacturing method of an electroplated grinding wheel with an ordered structure. Background technique [0002] Grinding processing technology is one of the most effective and widely used process technologies for precision processing and ultra-precision processing in modern machinery manufacturing. However, the grinding process generates a lot of heat, which accumulates on the surface of the workpiece to form a local high temperature, which can easily cause thermal damage to the workpiece. The traditional grinding wheel has a low degree of abrasive grains and a small chip space. The grinding wheel is easily blocked, which intensifies the generation and accumulation of grinding heat. At the same time, the grinding wheel is in close contact with the workpiece, which makes it difficult for the grinding fluid to effectively enter the contact area and cools the grinding area...
