Problems solved by technology

[0003] However, due to the many impurities in the existing oil stone manufacturing process, the degree of adhesion of the oil stone is not enough, the strength and hardness are poor, and there are defects such as not sharp, easy to break, and not wearable.

Embodiment 1

[0020] The invention provides a method for manufacturing a whetstone, which includes the following steps in the manufacturing process of the whetstone:

[0021] Mix and stir the white corundum micropowder containing impurities and the reinforcing resin bond to form a mixed solution, then pour the mixed solution into a filter tank, which is provided with twelve layers of filter nets, along the top-to-bottom In the filtering direction, the mesh of the filter becomes thinner gradually, and the fineness of the mesh of the filter from top to bottom is set as: 140 mesh, 160 mesh, 220 mesh, 300 mesh, 380 mesh, 580 mesh, 780 mesh, 900 mesh, 1000 mesh, 1200 mesh, 1800 mesh and 2800 mesh. The coarser mixture in the mixed solution stays on the filter screen located above, the finer mixture stays on the filter screen located below, and the impurities of the white corundum micropowder in the mixed solution flow out of the filter tank along with the remaining liquid substances , thus formi...

[0025] Mix and stir the white corundum micropowder containing impurities and the reinforcing resin bond to form a mixed solution, then pour the mixed solution into a filter tank, which is provided with twelve layers of filter nets, along the top-to-bottom In the filtering direction, the mesh of the filter becomes thinner gradually, and the fineness of the mesh of the filter from top to bottom is set as: 150 mesh, 180 mesh, 240 mesh, 320 mesh, 400 mesh, 600 mesh, 800 mesh, 1000 mesh, 1200 mesh, 1500 mesh, 2000 mesh and 3000 mesh. The coarser mixture in the mixed solution stays on the filter screen located above, the finer mixture stays on the filter screen located below, and the impurities of the white corundum micropowder in the mixed solution flow out of the filter tank along with the remaining liquid substances , thus forming a layer of oil stone blank to be sintered on each filter screen. Irregular white corundum powder is impacted by the flow of the reinforced resin binde...

Abstract

The invention discloses a manufacturing method of oil stone. The manufacturing method comprises steps as follows: white corundum micro powder containing impurities and a reinforced resin binder are mixed and stirred, a mixed solution is formed and poured into a filtering tank, at least two layers of filter nets are arranged in the filtering tank, meshes of the filter nets gradually become smaller from top to bottom in the filter direction, thicker mixtures in the mixed solution are left on the filter net above, finer mixtures are left on the filter net below, the impurities of the white corundum micro powder in the mixed solution flow out of the filtering tank along with remaining liquid substances, and accordingly, a layer of to-be-sintered oil stone initial blank is formed on each filter net. The manufacturing method has the benefit of improvement of the hardness and the keenness of the oil stone.

Description

technical field [0001] The invention relates to a method for manufacturing abrasive abrasives. More specifically, the present invention relates to a method for producing whetstone. Background technique [0002] Whetstones are generally used for manual grinding of tools and parts, and can also be clamped on machine tools for honing and superfinishing. There are two types of whetstones: man-made and natural. Artificial whetstones have two types of structures due to the different abrasives used. [0003] And because there are many impurities in the existing oilstone manufacturing process, the degree of bonding of the oilstone is not enough, the strength and hardness are relatively poor, and there are defects that are not sharp, easy to break, and not wearable. So there is an urgent need for a high hardness, sharp oilstone to make it wear-resistant and not easy to break during grinding. Contents of the invention [0004] It is an object of the present invention to solve at ...
