Abstract
The utility model relates to a penetrating type resin bond CBN grinding wheel with double end surfaces, which comprises a grinding wheel basal body made of aluminum alloys or steel. A CBN grinding layer is bonded on the surface of the grinding side of the grinding wheel basal body. The grinding wheel is characterized in that seven grinding areas are arranged on the CBN grinding layer on the surface of the grinding wheel basal body: a grinding area a, a grinding area b, a grinding area c, a grinding area d, a grinding area e, a grinding area f and a grinding area g, wherein the grinding areas from a to c are coarse grinding areas, and the grinding areas from d to g are fine grinding areas. The grinding wheel adopts seven grinding areas so as to continuously complete the processing process from coarse grinding to fine grounding. The effect on processing a work-piece once is equivalent to the effect after three-time processing, thereby saving time for grinding twice, feeding and discharging and enhancing the processing efficiency of the work-piece by more than 400%.
Description
Technical field
The utility model relates to a kind of grinding tool, particularly relates to a kind of resin cement cubic boron nitride (hereinafter to be referred as CBN) penetration type Double End emery wheel, is to the improvement of existing resinoid bond CBN Double End grinding wheel structure, belongs to the super-hard abrasive tool manufacturing technology.
Background technology
The required precision height of the mechanical sealing member of Aeronautics and Astronautics industry, workpiece such as refrigeration accessory, piston of automobile ring and brake block etc., the material that is adopted be high-speed steel all generally, ooze difficult grind materials such as charcoal steel, stainless steel, cast iron.Problems such as domestic production producer uses the traditional double face grinding machine usually at present, adopts the Double End abrasion wheel grinding workpiece of materials making such as conventional carborundum, corundum, and it is low to exist grinding efficiency, and workpiece is yielding.And adopt resinoid bond CBN Double End abrasion wheel grinding workpiece and common grinding tool relatively, have characteristics such as the high grinding accuracy height of grinding efficiency, the difficult burn of workpiece, distortion, therefore, strong manufacturer all selects numerical control Double End grinder, with resinoid bond CBN Double End abrasion wheel grinding workpiece.Because the general grinding operation is: rough lapping → grinding → smooth grinding, exist operation length, more problem consuming time, along with the continuous development of industries such as China's space flight, aviation, automobile, refrigeration, the user proposes further to improve the requirement of grinding efficiency to grinding tool manufacturer.
Summary of the invention
The purpose of this utility model just is to overcome the prior art above shortcomings, improve grinding process length, more problem consuming time, improve the grinding efficiency of workpiece, provide a kind of novel resinoid bond CBN and wear formula Double End emery wheel, this CBN emery wheel adopts seven workspaces, adopts the penetration type grinding in grinding method, is promptly fed by the side of grinding work-piece by the CBN emery wheel, provide by opposite side through attrition process, in grinding, once finish the process from the rough lapping to the smooth grinding.The rough lapping in the minimizing grinding process and the process of grinding make the workpiece time processing reach the effect of three processing.Save the time of twice grinding and upper and lower material, improve unit workpiece grinding efficiency more than 300%.
The technical solution that the utility model provides is: this resinoid bond CBN wears formula Double End emery wheel, including with alloy aluminum or iron and steel is the grinding wheel base body of material, be bonded with the CBN wear layer on the surface of grinding one side of grinding wheel base body, be characterized in that the granularity by abrasive material is provided with 7 in mill district on the described grinding wheel base body surface C BN wear layer, be respectively: milling zone a, milling zone b, milling zone c, milling zone d, milling zone e, milling zone f, milling zone g, milling zone a wherein, milling zone b, milling zone c is the rough lapping district, milling zone d, milling zone e is middle milling zone, milling zone f, milling zone g is the fine lapping district.
It is to arrange according to the grinding resistance of different workpieces and linear velocity that the CBN abrasion wheel grinding is divided into seven workspaces, and each grinds workspace abrasive material prescription and requires decide according to the grinding of different workpieces, and the dressing that respectively grinds workspace abrasive material difference, proportioning of proportioning is difference also.Each grinds the workspace abrasive concentration and density will be according to the material and the processing capacity of workpiece, and each consumption situation of grinding the workspace is calculated behind the compression ratio of each milling zone and decided.Above-mentioned designing and calculating work belongs to one of ordinary skill in the art's required technical knowledge and skills.
Compared with prior art, the beneficial effects of the utility model are: adopt seven to grind the workspace, by the abrasive material prescription design of each workspace area design and each workspace, once finish the process from the rough lapping to the smooth grinding in grinding.The rough lapping in the minimizing grinding process and the process of grinding make the workpiece time processing reach the effect of three processing.Save the time of twice grinding and upper and lower material, improve unit workpiece working (machining) efficiency more than 400%.
