Abstract
A large-external-diameter and large-thickness CBN (Cubic Boron Nitride) cylindrical grinding wheel comprises a matrix and a paster tool bit on the cylindrical surface of the matrix, and is characterized in that the paster tool bit consists of a wide paster tool bit and a narrow paster tool bit which are paired and fixed on the matrix alternatively. The width of the narrow paster tool bit is one fifth to four fifths that of the wide paster tool bit. The thickness of the narrow paster tool bit is identical with or different from that of the wide paster tool bit. According to the utility model, the shape of the paster tool bit is changed into the narrow paster tool bit and the wide paster tool bit, and the wide paster tool bit and the narrow paster tool bit are paired and adhered on the cylindrical surface of the matrix alternatively. The problems that the paster tool bit of the large-external-diameter and large-thickness CBN cylindrical grinding wheel is difficult to realize up and down density uniformity of a cold pressing tool bit due to existence of pressure gradient can be solved. The cylindrical tool bit density of the grinding wheel is uniform during the use process of the CBN cylindrical grinding wheel, the taper problem of the grinding wheel and workpieces is eliminated, and the machining quality of the grinding wheel is improved.
Description
Technical field
The utility model relates to the high thickness C BN peripheral milling of a kind of big external diameter emery wheel, belongs to super-hard abrasive tool manufacturing technology field.
Background technology
Common big external diameter CBN peripheral milling emery wheel is used the paster cutter head, and its cutter head height is all greater than 40mm, and the paster cutter head is a disposal pressed moulding, and monoblock sticks on the matrix periphery behind the sintering, is used for the machining crankshafts series products.This type paster cutter head aspect ratio is higher, and this specific character has determined in the process of colding pressing, because the existence of barometric gradient is difficult to realize that lower density is even on the cutter head.This just causes CBN peripheral milling emery wheel in the process of using, cylindrical both sides cutter head density unevenness, and tapering appears in emery wheel and workpiece, causes crudy not reach requirement.Therefore, be necessary further improvement and perfect.
The utility model content
The purpose of the utility model aim to provide lower density on a kind of simple and reasonable, cutter head evenly, paste firmly, the high thickness C BN peripheral milling of the big external diameter emery wheel of long service life, to overcome weak point of the prior art.
The high thickness C BN peripheral milling of a kind of big external diameter emery wheel by this purpose design; The paster cutter head that comprises matrix and outer round surface thereof; Its architectural feature is that the paster cutter head is divided into wide paster cutter head and narrow paster cutter head, and pairing of width paster cutter head and staggered being fixed on the matrix.
The width of said narrow paster cutter head is the 1/5-4/5 of wide paster cutter head.
Said narrow paster cutter head is identical or inequality with wide paster cutter head thickness.
Said narrow paster cutter head is identical with the material of wide paster cutter head, is vitrified bond CBN paster cutter head.
Described matrix is an alloy matrix aluminum, and outer round surface is provided with the groove of strengthen pasting, and the paster cutter head sticks on the matrix outer round surface.
The utility model changes the shape of paster cutter head, is designed to two kinds of paster cutter heads of width, and with pairing of width paster cutter head and staggered being pasted on the matrix periphery.Solved because the existence of barometric gradient, the uniform problem of lower density on external diameter, the very difficult cutter head of realizing colding pressing of high thickness C BN peripheral milling emery wheel paster cutter head greatly.Make CBN peripheral milling emery wheel in the process of using, the cutter head density of emery wheel cylindrical is even, has eliminated the tapering problem that emery wheel and workpiece produce, and the crudy of emery wheel is improved.It is simple and reasonable, and the cutter head density of colding pressing is even, can not produce the phenomenon of density unevenness up and down.Be specially adapted to the paster cutter head of big external diameter, high thickness C BN peripheral milling emery wheel.
Description of drawings
Fig. 1 is the utility model one example structure sketch map.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, supposes that the paster cutter head requires the high 50mm that is.
As shown in Figure 1, the high thickness C BN peripheral milling of a kind of big external diameter emery wheel is made up of matrix 1, narrow paster cutter head 2, wide paster cutter head 3 and matrix cylindrical straight trough 4.
During making, adopt alloy matrix aluminum, and leave straight trough 4, to increase sticking strength at matrix 1 cylindrical as matrix material.Narrow paster cutter 2 head height degree are designed to 30mm, and wide paster cutter head 3 highly is designed to 20mm, carries out sintering after the compression moulding.Narrow paster cutter head behind the sintering 2 and wide paster cutter head 3 pairings are pasted, and staggered being pasted on matrix 1 periphery, after the curing emery wheel external diameter is machined to the size of design.
The narrow paster cutter head 2 of present embodiment highly is designed to 28mm, and wide paster cutter head 3 highly is designed to 22mm, carries out sintering after the compression moulding.Narrow paster cutter head behind the sintering 2 and wide paster cutter head 3 pairings are pasted, and staggered being pasted on matrix 1 periphery, after the curing emery wheel external diameter is machined to the size of design.
The narrow paster cutter head 2 of present embodiment highly is designed to 26mm, and wide paster cutter head 3 highly is designed to 24mm, carries out sintering after the compression moulding.Narrow paster cutter head behind the sintering 2 and wide paster cutter head 3 pairings are pasted, and staggered being pasted on matrix 1 periphery, after the curing emery wheel external diameter is machined to the size of design.
