Abstract
The utility model relates to a cubic boron nitride internal grinding wheel with a spiral groove on the surface. The internal grinding wheel comprises a screw rod, a CBN grinding wheel layer, wherein the CBN grinding wheel layer is arranged at the grinding head position of the screw rod. The utility model is characterized in that a spiral groove is arranged on the outer surface of the CBN grinding wheel layer. The inclination angle of the ceramics of the spiral groove is 45 to 60 degrees, and the width is 1.5 to 2 mm. The utility model has the advantages that the cooling effect is good, the chip removal is smooth, and the phenomena of thermal damage and scuffing to the work piece surface can not be generated.
Description
Technical field
The utility model relates to a kind of surface and has circle grinding abrasive disk in the spiral fluted pottery cubic boron nitride (CBN), is used for the efficient mill processing of column type through hole, blind hole internal surface, belongs to super-hard abrasive tool manufacturing technology field.
Background technology
The circle grinding abrasive disk is used the high strength structure glue bond together by CBN abrasive material and screw head in the common CBN.CBN abrasive material outer surface is certain complete cylindrical surface.The internal grinding mode has determined that distinct issues are in its grinding process: cooling fluid is difficult to reach grinding area, thereby has caused cooling effect poor.And the temperature of grinding area generally will be up to more than 600-1000 ℃; cause the fire damage of surface of the work easily, and, also cause the defectives such as scuffing of grinding skin through regular meeting because chip removal is not smooth; under the high-speed grinding state and during the grinding blind hole, the problems referred to above are more outstanding especially.
Summary of the invention
The purpose of this utility model provides a kind of good cooling results, can not cause that the surface of the fire damage of surface of the work has circle grinding abrasive disk in the spiral fluted pottery cubic boron nitride.
For realizing above purpose, the technical solution of the utility model provides a kind of surface and has circle grinding abrasive disk in the spiral fluted pottery cubic boron nitride, comprises screw rod, CBN emery wheel layer, and CBN emery wheel layer is located at the bistrique position of screw rod, it is characterized in that, on CBN emery wheel layer outer surface, be provided with helicla flute.
Described helicla flute inclination angle is 45 °-60 °, and width is 1.5mm-2mm.
The utility model is left helicla flute on the emery wheel appearance face of cylinder, allow the cooling fluid crossheading enter grinding area, grinding fluid the implementation of supply measurement in use, good cooling results, the heat of about 60-80% that grinding can be produced is taken away, and abrasive dust also can be discharged by crossheading, solved the shortcoming of chip removal difficulty simultaneously, the cooling and the chip removal problem of circle mill in effectively solving, reduced grinding heat workpiece has been caused burn, the possibility of defectives such as crackle, the surface quality of processing work has clear improvement, and grinding efficiency is proposed certain raising, especially be suitable for the internal grinding of high-speed and high-efficiency grinding and blind hole, reduce the phenomenon that workpiece surface roughness and bore area scratch simultaneously.
The utility model has the advantages that good cooling results, chip removal is smooth and easy, can not produce phenomenons such as the fire damage of surface of the work and division.
Description of drawings
Fig. 1 has circle grinding abrasive disk structural representation in the spiral fluted pottery cubic boron nitride for the surface.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, for the surface has circle grinding abrasive disk structural representation in the spiral fluted pottery cubic boron nitride, described surface has the interior circle of spiral fluted pottery cubic boron nitride grinding abrasive disk and is made up of screw rod 1 and CBN emery wheel layer 2.
During making, the CBN emery wheel layer 2 that sintering is crossed is bonded in the bistrique position of the screw rod 1 that processes by design drawing, reach intensity after, with special diamond abrasive cut-off wheel grooving on CBN emery wheel outer peripheral face, groove width 1.0mm, the wide 2.0mm of CBN emery wheel layer, helix become 30 ° of angles with the emery wheel bus.After the cutting of helix finishes, again the emery wheel external diameter is worked into the size of design.
Below be the inner hole grinding workpiece performance comparison table of compressor of air conditioner upper end cover:
Claims (2)
1. a surface has circle grinding abrasive disk in the spiral fluted cubic boron nitride, comprises screw rod (1), CBN emery wheel layer (2), and CBN emery wheel layer (2) is located at the bistrique position of screw rod (1), it is characterized in that, is provided with helicla flute (3) on CBN emery wheel layer (2) outer surface.
2. surface according to claim 1 has circle grinding abrasive disk in the spiral fluted cubic boron nitride, it is characterized in that described helicla flute (3) inclination angle is 45 °-60 °, and width is 1.5mm-2mm.
