Abstract
An abrasive disc with acicular abrasive particles is composed of a main body and the filler solidified in the cavity of main body. Said filler is composed of adhesive and acicular abrasive particles. Its preparing process includes such steps as making the mould of abrasive disc, mixing the optically solidified resin with acicular abrasive particles to become filler, filling the filler in the solidifying cavity of mould, and optical solidifying.
Description
One, technical field
The present invention relates to a kind of needle-shape abrasive particle grinding wheel and preparation method thereof.
Two, background technology
Emery wheel is that a large amount of main tool of using also are main consumptive materials simultaneously in the machinery manufacturing industry, and the abrasive particle of hard materials such as diamond, cubic boron nitride has obtained using widely in accurate emery wheel manufacturing industry.But people adopt regular geometric shape to the graininess of abrasive particle, and abrasive particle is easy to come off, thereby causes emery wheel to consume gradually, and service life is short.
Three, summary of the invention
The present invention seeks to solve existing emery wheel, and abrasive particle comes off easily, emery wheel short shortcoming in service life owing to the abrasive particle fixed structure causes, and it is emery wheel of needle-like, long service life and preparation method thereof that a kind of abrasive particle is provided.
For this reason, the present invention takes following technical scheme:
A kind of needle-shape abrasive particle grinding wheel, by grinding wheel base body and be filled in grinding wheel base body and solidify inserts in the chamber and solidify and form, described inserts is made up of bond and abrasive particle, and described abrasive particle contains the needle-shape abrasive particle through the externally-applied magnetic field orientation.
Described bond is the light-cured resin bond.
Described light-cured resin bond mainly is made up of epoxy acrylate, two functional group's diluents, trifunctional diluent, ultraviolet initiator.
Described abrasive particle is the needle-shape abrasive particle through the externally-applied magnetic field orientation entirely.
Described abrasive particle is the carborundum of coating surface nickel alloy and through the needle-shape abrasive particle of externally-applied magnetic field orientation.
Described needle-shape abrasive particle is that nickel alloy plating carborundum is carried out on the surface.
Abrasive particle accounts for the 10%-55% of cumulative volume in the described inserts.
Described emery wheel is by the inserts curing molding that is filled in the grinding wheel base body curing chamber, described inserts is made up of bond and abrasive particle, described abrasive particle is the needle-shape abrasive particle that contains through the externally-applied magnetic field orientation, and described preparation method specifically may further comprise the steps: (1) makes grinding wheel die; (2) batch mixing: light-cured resin and needle-shape abrasive particle are uniformly mixed into inserts with mixer; (3) externally-applied magnetic field makes the needle-shape abrasive particle orientation; (4) curing molding: inserts is filled in the curing chamber of mould the illumination curing moulding.
The preparation method of a kind of photo sensitive resin binding agent sand wheel of the present invention has following advantage:
1, use needle-shape abrasive particle, that is, it is that tens of microns are to hundreds of microns to tens of microns, major diameter that the minor axis of abrasive particle is several microns, adopt externally-applied magnetic field to make the abrasive particle orientation, make the major diameter of abrasive particle all point to the radial direction of emery wheel, make the major diameter termination participate in grinding, thereby reach the characteristics of long service life; Also can adopt extra electric field to reach the effect of abrasive particle orientation herein, but adopt this kind technological requirement height, need the configuration high-voltage DC power supply, the cost height, and also there is hidden danger in operation; 2, adopt illumination curing, make the preparation energy consumption low; 3, low cost of manufacture; 4, improved manufacturing environment simultaneously.
