Embodiment 1

[0020] The vitrified diamond grinding wheel mixed with iron powder is made of the following raw materials in parts by weight: diamond abrasive 53, brown corundum abrasive 17, phenolic resin powder 4, iron powder 6, naphthalene particles 1.5, dibutyl sebacate 1.6, tricresyl phosphate Ester 1.2, dolomite 4, borax 4, potassium feldspar 2, zinc oxide 1. The dolomite, borax, potassium feldspar, and zinc oxide are smelted at a high temperature of 2724° C., cooled, and ball-milled into nano-ceramic powder to become a vitrified bond.

[0021] The preparation method of the vitrified diamond grinding wheel mixed with iron powder comprises the following steps:

[0022] (1) Put each component into the mixer according to the above formula, mix for 1 hour, and mix well;

[0023] (2) Pour the mixture into the mold, then put the mold into the press for pressing, and heat the mold at the same time, first pre-pressurize 1 MPa, heat the upper and lower plates of the press at 310°C for 2...

Abstract

The invention discloses an iron-powder doped ceramic diamond grinding wheel which comprises the following components by weight: 50-60 parts of diamond abrasive, 15-20 parts of brown corundum abrasive, 4-6 parts of phenolic resin powder, 5-8 parts of iron powder, 1-3 parts of naphthyl grains, 1-3 parts of dibutyl sebacate, 1-2 parts of tricresyl phosphate, 4-8 parts of dolomite, 4-8 parts of borax, 2-4 parts of potassium feldspar and 1-3 parts of zinc oxide. Because the binding agents are ceramic materials, the grinding wheel is not easy to deform, has good heat resistance and high abrasion resistance. The various ceramic materials have good binding performance, can prevent the formation of cracks effectively and solves the problems that the existing grinding wheel has poor heat resistance and is easy to deform, the existing binding agents for producing the grinding wheel have poor performance, and the abrasives are easy to fall. Because the iron powder and other metal powders are added, the grinding wheel disclosed by the invention has high heat conducting performance, low grinding temperature and higher hardness and strength and can dissipate heat quickly, the cracks formed due to rigid grinding are reduced, the grinding efficiency and the service life of the grinding wheel are far higher and longer than those of the traditional grinding wheel, and the comprehensive benefit is improved by more than 50%.

Description

technical field [0001] The invention discloses a vitrified diamond grinding wheel mixed with iron powder and a preparation method thereof, belonging to the technical field of grinding tool processing. Background technique [0002] Grinding wheel is the most important type of abrasive tool in grinding process. The grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and firing. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing and Fine grinding as well as grooving and parting off etc. The substance used to bond the abrasive in the grinding wheel is called a bonding agent. The performance of the bonding agent determines the strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel. At present, the bonding agent is mainly divided into four types: ceramic, resin, rubber and metal, among which the ceramic bo...
