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 accompanying drawings.

[0024] see figure 1 , figure 2 and image 3 The electroplated grinding wheel with an ordered structure includes: a grinding wheel substrate 3 and an abrasive grain layer 8 in which the abrasive grains are arranged in an orderly manner. The material of the grinding wheel base 3 is high-strength aluminum alloy, with a diameter of 100-200mm and a thickness of 12-20mm. The outer circumferential working surface 4 of the grinding wheel base is provided with a spiral groove 5 with a fine structure. The width of the spiral groove 5 is 50-80 μm, the depth is 60-100 μm, and the pitch is 200-300 μm. The spiral groove is filled with epoxy resin 6 . The abrasive grain 7 is made of cubic boron nitride or diamond, and is fixed on the grinding wheel base 3 through a nickel-cobalt alloy coating.

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 method for manufacturing a grinding wheel, in particular to a method for manufacturing an electroplated grinding wheel with an ordered structure. Background technique [0002] Grinding technology is one of the most effective and widely used technologies for precision machining and ultra-precision machining 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 sharpness of the abrasive grains, a small space for the chip of the grinding wheel, and 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, making it difficult for the grinding fluid to enter the contact area effectivel...
