Description
Technical field
The utility model relates to vitrified bonded grinding wheel technical fields, and in particular to a kind of multi-layer ceramics binding agent sand wheel.
Background technique
In machining industry, it is often necessary to workpiece are ground to scheduled precision with grinding wheel grinding tool, it is generally the case that one
The grinding of workpiece will require replacement abrasive grain by the repeatedly grinding such as corase grinding, fine grinding and fine grinding after the completion of each grinding
Smaller grinding wheel, until workpiece is ground to scheduled precision, the frequent replacement of grinding wheel and substep are ground so that when work pieces process
Between it is longer, seriously affect working efficiency；In addition, carrying out substep grinding using the grinding wheel of a variety of different abrasive grains, replace every time
It requires to modify new grinding wheel after grinding wheel, it is not only time-consuming, and also waste of resource, processing cost consumption are larger.
Utility model content
The purpose of the utility model is to provide a kind of multi-layer ceramics binding agent sand wheels, can using the grinding wheel of the utility model
The work pieces process time is substantially reduced, processing efficiency is improved, reduces processing cost.
In order to solve the above technical problems, the basic conception of the used technical solution of the utility model is: by the time of molding
The abrasive material of different grain size, different hardness is combined by different level using vitrified bond as binder, becomes a kind of Ceramic bond
Agent grinding wheel, for example, by by abrasive grain it is descending be divided into corase grinding layer, fine grinding layer and fine grinding layer (in contrast three is
) three levels；By being combined in multiple grinding granularity, (refer to every layer by thickness of the actual demand to multi-level abrasive material
Along axial thickness) be allocated (such as corresponding abrasive material is set by corase grinding, fine grinding, the corresponding grinding time scale of fine grinding
Thickness proportion), then so that multilayer abrasive material is fused into an entirety by high temperature sintering；When in use, pass through grinding wheel and workpiece
Grinding wheel axial direction relative movement and grinding wheel around own axes rotation, make the same working position of workpiece (being denoted as A point) corase grinding,
Fine grinding and precision grinding step are carried out continuously, and to a position under workpiece (being denoted as B point) roughly grind while, fine grinding layer to A point into
Row fine grinding, when grinding wheel roughly grinds next one position (being denoted as C point) of workpiece, fine grinding layer carries out fine grinding to B point, refines layer
A point is refined, when there is more layers, and so on, it not only saves replacement grinding wheel, correct the time of grinding wheel, and make workpiece
The time of corase grinding is approximately equal to and (is actually slightly larger than) total time of grinding (while because of completion is roughly ground to C point, to B point
Fine grinding and the fine grinding of A point be synchronize carry out, therefore pilot process is not needed to calculate fine grinding and be refined the time, only whole in workpiece
The stage that body completes the process calculates the fine grinding time), the work pieces process time is greatly reduced, processing efficiency is improved, subtracts simultaneously
Lack grinding wheel times of revision, reduced resource waste, reduces processing cost.
Based on above-mentioned basic conception, it is that technical solution is that the utility model, which uses: a kind of multi-layer ceramics binding agent sand wheel,
Grinding wheel is integrally annular in shape, and for grinding wheel along being axially multilayered structure, every layer is a circular abrasive material, the abrasive material of each abrasive material
Granularity is reduced along axial direction by grinding wheel one end to the other end step by step.
The abrasive material has three layers, is divided into corase grinding layer, fine grinding layer and fine grinding layer by abrasive grain is descending.
It is integrally sintered between each abrasive material.
It is cooperatively connected between different abrasive materials in dentation.
In a kind of embodiment of the utility model: each abrasive material along grinding wheel axial direction thickness with abrasive grain reduce and
Reduce.
In the another embodiment of the utility model: each abrasive material reduces along the thickness of grinding wheel axial direction with abrasive grain
And increase.
The utility model has the advantages that the utility model is by carrying out multilayer sub-distribution combination in different abrasive grains or/and different hardness,
Then multi-layer ceramics binding agent sand wheel entirety is fused by high temperature sintering, working efficiency, fewer resource is improved to reach with this
Waste, reduce the purpose of cost；The utility model is practical, operates fairly simple, can be in Grinding Process
Same part workpiece grinding accuracy to be achieved can be realized without replacing other specification grinding wheel grinding tools, improve grinding wheel die
Grinding performance, improve work efficiency, save resource and cost.

Specific embodiment
The utility model is described in more detail in the following with reference to the drawings and specific embodiments；Non- detailed portion below
It is the prior art or can be realized using the prior art.
Embodiment 1
Referring to figs. 1 to Fig. 3, a kind of multi-layer ceramics binding agent sand wheel, grinding wheel is integrally annular in shape, and grinding wheel includes three layers of outer diameter
Identical abrasive material, i.e. corase grinding layer 1, fine grinding layer 2 and fine grinding layer 3, corase grinding layer 1, fine grinding layer 2 and fine grinding layer 3 along grinding wheel it is axial according to
It is secondary to be arranged side by side, and the abrasive grain for roughly grinding layer 1, fine grinding layer 2 and fine grinding layer 3 is sequentially reduced；
It is cooperatively connected between corase grinding layer 1 and fine grinding layer 2 and between fine grinding layer 2 and fine grinding layer 3 in dentation；
Corase grinding layer 1, fine grinding layer 2 and fine grinding layer 3 are integrated sintering；
The width of corase grinding layer 1, fine grinding layer 2 and fine grinding layer 3 is sequentially reduced；
The preparation method of the grinding wheel, includes the following steps:
Step 1: preparing abrasive material to abrasive grain requirement by each abrasive material, and mixed respectively with vitrified bond, obtains phase
The molding mass answered；
Step 2: molding die is cleaned out, molding die includes lower platen, die sleeve, plug and top board, in die sleeve
Diameter is equal to grinding wheel outer diameter, and diameter of mandrel is equal to grinding wheel internal diameter, and top board and lower platen outer diameter annular in shape and the two are equal to sand
Take turns outer diameter, internal diameter is equal to grinding wheel internal diameter；
Step 3: die sleeve is placed on work top, lower platen is put into die sleeve, and plug is inserted into lower platen inner hole, rubbing
The ascending substep of material granularity puts into molding mass into molding die, and by respective thickness, when grinding wheel total volume turns every kind of molding mass
The volume for turning to this kind of molding mass is added, it is every throw a kind of molding mass after, upper surface is spread in being with grinding wheel axial line
The dentation (referring to figs. 2 and 3) of the circle distribution of the heart, then a kind of molding mass is cast, a kind of last molding mass investment molding die
