It is transsexual good, convenient for rapid changing knife etc. a little；Cutter life is high simultaneously, and cutting ability is reliable and stable；Cutter should be able to be reliably simultaneously
Chip breaking or volume bits, in favor of effective discharge of chip；The production that organic glass is particularly carried out in numerical control machining center lathe adds
During work, as soon as traditional cutter structure can only carry out the perforate work operations of time organic glass, needed in refine hole face
Finishing tool is replaced, so, manpower and materials, and low production efficiency is not only wasted, greatly constrains industrialization
The demand of production so in order to coordinate perforate work operations of the numerical control machining center to organic glass, designs a kind of new gold
Hard rock abrasive material drill bit just seems unusual necessity.
The content of the invention
The goal of the invention of the utility model；
Primarily to provide a kind of new mill of the perforate operation processing suitable for numerical control machining center organic glass
Expect drill bit structure so that the technical process of complete fulfillment roughing and finishing in the hole opening technology of organic glass has simultaneously
The material hardness for improving diamond cutter of effect improves the grinding accuracy in Tapping procedures, effectively reduces the labor of worker
Fatigue resistance improves the production efficiency of enterprise, improves the economic benefit of enterprise.
The technical solution of the utility model is：
A kind of double-deck abrasive material drill bit is provided, including grip shank, the front end of grip shank is provided with the essence of trapezoidal structure
Abrasive matrix is stacked in the fine grinding bed of material one between the essence abrasive matrix by electroplating processes, set in the front end of the fine grinding bed of material one
There is the corase grinding bed of material one, the grinding radius for roughly grinding the bed of material one is mutually matched with refining the grinding radius of the bed of material one；In the corase grinding bed of material one
Front end by the corase grinding bed of material one the transition shaft shoulder that sets be connected with the fine grinding bed of material two, set in the front end of the fine grinding bed of material two
There is bit body, coarse grained abrasive layer two is electroplate on bit body, the grinding radius of the corase grinding bed of material two is less than the grinding of the fine grinding bed of material two
Radius.
The blade of four arcs is provided on the bit body, is connected between the blade and the fine grinding bed of material two by buckling groove
Fixation is connect, discharge launder is further opened on blade.
The diamond dust of 1000 mesh is plated on the fine grinding bed of material one and the fine grinding bed of material two.
The diamond dust of 400 mesh is plated on the corase grinding bed of material one and the corase grinding bed of material two.
The beneficial effects of the utility model are：
During the new type abrasive drill bit structure of the structure setting processes organic glass especially suitable for numerical control machining center
Perforate operation technique process so that organic glass the roughing of hole opening technology complete fulfillment and finishing production process, together
When effectively raise the material hardness of diamond cutter, improve the grinding accuracy in Tapping procedures, effectively reduce worker
Labor intensity, improve the production efficiency of enterprise, improve the economic benefit of enterprise.
