Abstract
The utility model relates to a novel alumina hollow ball for specialized pore-forming of a grinding wheel, and the novel alumina hollow ball is characterized in that hotly-melted alumina powder is adopted as the material; each hollow ball is a ball which is hollow; the hollow balls with different diameters are sieved and separated through a sieve; and during manufacture of grinding wheels, the hollow balls can be used with other bonding agents. The novel alumina hollow ball has the advantages of strong chip-removal ability, fast heat radiation, no air pollution, and no harm to human body, and meanwhile reduces cost and improves the grinding effect and the sharpness degree of the grinding wheel.
Description
Technical field
The utility model relates to a kind of novel emery wheel specialty pore-creating alumina hollow ball in the grinding materials and grinding tool industry.
Background technology
The air hole grinding wheel of domestic production now, making material has the perlite of employing to make as material, but because perlite is soft rock, pattern is also irregular, pore-forming varies, chip removal phenomenon in the grinding process is not too desirable, also since become pore opening not wait, having limited its revolving strength has influenced ground effect; Make naphthalene ball gas making hole with chemical materials refined naphthalene powder in the production of conventional resins emery wheel, cause the inside and outside smell of factory building to stimulate unpleasant, injury human body, polluted air, oil everywhere in process of production, go back etching apparatus; Vitrified grinding wheel adopts Cortex walnut, wood chip, corn ear grain to come pore-creating in producing mostly, and pore-forming is irregular, has limited its revolving strength, influences the safety and stablization of quality product.
Summary of the invention:
The purpose of this utility model is in order to solve above-mentioned deficiency, a kind of novel emery wheel pore-creating material--hollow ball is provided, this material is to make after adopting the aluminum oxide powder high temperature melt, hollow ball (1) is a sphere-like, spheroid is hollow (2), and then the hollow ball of different diameter gone out with the screen cloth sieving separating, the wedding agent that is equipped with other when making emery wheel again uses together.
The utility model, it is strong to have a chip removal, and rapid heat dissipation is tasteless, does not have atmospheric pollution, and human body is not had injury, can reduce cost again and can improve the ground effect and the sharpness of emery wheel.
Description of drawings:
Fig. 1 is the utility model synoptic diagram
Embodiment:
After being melted by aluminum oxide powder, makes a kind of novel emery wheel specialty of the utility model shown in Fig. 1 pore-creating alumina hollow ball, at first the electricity consumption method of melting is melted into liquid with aluminum oxide powder, melting temperature generally is 2300 degrees centigrade, little by little be blow molded into bead with air compressor melting good aluminum oxide powder then, spheroid becomes hollow shape, with screen cloth hollow ball is filtered to sort out in the size according to sphere diameter then, can be when making emery wheel according to the object difference of grinding, the hollow ball 1 that hardness different choice diameter is different is equipped with normal wedding agent again and makes emery wheel, the emery wheel chip resistance that the big more made of the diameter of hollow ball 1 comes out is high more, the grinding sharpness of emery wheel is high more, use the efficient height, produce also very convenient.
Claims (2)
1. a novel emery wheel specialty pore-creating alumina hollow ball is characterized in that hollow ball (1) is a sphere-like, and spheroid is hollow (2).
2. a kind of novel emery wheel specialty pore-creating alumina hollow ball according to claim 1 is characterized in that hollow ball (1) is to make after adopting the aluminum oxide powder electricity to melt.
