Example Embodiment

[0018] Example: A high-efficiency alumina ceramic microcrystalline abrasive precision grinding wheel, which comprises a grinding wheel base, abrasive particles distributed on the grinding wheel base, and bonding and fixing the abrasive particles on the grinding wheel base The binding agent, the binding agent includes the following components in weight ratio:

[0019] Clay powder 10-15

[0020] Feldspar powder 30-50

[0021] Talc 20-40

[0022] High boron glass powder 10-20.

[0023] The main component of the bonding agent in this embodiment is a clay-feldspar-high glass-based bonding agent. In addition, temporary adhesives and wetting agents are required. A pore-forming agent may be used according to needs, and the pore-forming agent is walnut shell particles or naphthalene particles or a mixed particle of the two. The components of the binder should be mixed uniformly before use. At the same time, the particle size of the binder powder should be controlled within 40nm. Then it is...

Abstract

The invention relates to a precision grinding wheel for high-efficiency aluminum oxide ceramic microcrystalline grinding materials, comprising a grinding wheel basal body, grinding material particles distributed on the grinding wheel basal body and a bonding agent bonded and fixed on the grinding material particles, wherein the bonding agent comprises the following components in percentage by weight: 10-15 clay powder, 30-50 feldspar powder, 20-40 talcum powder and 10-20 high-boron glass powder. The grinding wheel has the functions of large cutting depth, high feeding strength, large load and high-efficiency grinding. According to tests, over 0.3 mm can be reached for one-way feeding and the metal removing rate is over 2 times higher than that of a common corundum grinding wheel. The grinding wheel ahs the advantages of high durability, long service life which is 5-10 times that of the common corundum grinding wheel, favorable self sharpening, no blockage and high capability of maintaining stable grinding performance.

Description

technical field [0001] The invention relates to the field of abrasive abrasives, in particular to an alumina ceramic microcrystalline abrasive grinding wheel Background technique [0002] Abrasives have been compared to "industrial teeth", which vividly reflects its inseparable relationship with modern industry. It shows that it is an indispensable tool for industrial development. Now with the development of the abrasives industry, it has been widely used in various industries and fields. The types of existing abrasives include ordinary abrasives: brown corundum grinding wheel, white corundum grinding wheel, single crystal corundum grinding wheel, microcrystalline corundum grinding wheel, chrome corundum grinding wheel, zirconium corundum grinding wheel, green silicon carbide grinding wheel, black silicon carbide grinding wheel; superhard materials Aspects include diamond grinding wheels and cubic boron nitride (CBN) grinding wheels. [0003] Among the grinding wheels such...
