Problems solved by technology

As we all know, in order to make the steel ball grinding wheel have higher durability, the hardness of the grinding wheel is higher, and the grinding efficiency will decrease at this time; on the contrary, if the grinding efficiency is to be improved, the hardness of the grinding wheel must be reduced, and the durability will decrease

Embodiment Construction

[0007] Formulate the grinding wheel formula as follows:

[0008]

[0009] Accurately weigh various materials according to the formulas of the above-mentioned Example 1, Example 2, and Example 3 respectively, put them into a ball mill after mixing, discharge and sieve after ball milling, and make emery wheels according to conventional methods. After the grinding wheel made according to Example 1 was tested in a steel ball factory in Hefei, the discharging time of each ball was reduced from 10 hours to 7.5-8 hours, and the grinding efficiency was increased by 20-25%. After the grinding wheel manufactured according to Example 2 was tested in a steel ball factory in Changzhou, each grinding wheel was improved from grinding 36 balls to grinding 40-41 balls, and the durability increased by 11.11-13.88%. After the grinding wheel made according to Example 3 was tested in a steel ball factory in Zhejiang, the discharge time of each ball was reduced from 10 hours to 8-8.5 hours, and ...

Abstract

The invention discloses a formula for grinding steel balls and grinding wheels. The raw materials and parts by weight are as follows: 18 to 24 parts of brown corundum abrasive, one of white corundum abrasive and single crystal corundum abrasive or a mixture of both in any proportion6 ~12 parts, silicon carbide abrasive 20 parts, feldspar 28-32 parts, clay 15-19 parts, boron glass 2-4 parts. In the present invention, one or both of white corundum abrasive and single crystal corundum abrasive is added to the brown corundum abrasive, and the steel ball grinding wheel produced maintains the original characteristics in terms of hardness and density, and its grinding efficiency is improved. It has increased by more than 20%, especially after adding single crystal corundum abrasive, the durability of the grinding wheel has increased by about 10%. Not only that, because the impurities in white corundum abrasives and single crystal corundum abrasives are much smaller than brown corundum abrasives, it can effectively improve the authenticity rate of products. Therefore, the present invention not only improves the product quality, but also saves a large amount of manpower and financial resources for the manufacturers, and the comprehensive social benefits are very obvious.

Description

technical field [0001] The invention relates to a formula for grinding steel balls and grinding wheels with a vitrified bond, which is mainly used for making grinding wheels for grinding spherical steel balls. Background technique [0002] Steel ball grinding wheel is a special grinding wheel for grinding spherical steel balls with a diameter below 76.20mm. It has the characteristics of large size, fine particle size, high hardness, and high density. It is widely used in machinery and bearing industries. At present, all steel ball grinding wheel manufacturers use brown corundum and silicon carbide mixed abrasives to manufacture steel ball grinding wheels in formula design. There is a certain limit, so the grinding wheel is required to have a large shrinkage after burning to increase the density of the grinding wheel. The refractoriness of the binder should not be too high. Therefore, if the fine-grained abrasive of a single brown corundum is used, because of the high impuri...
