この発明は、たとえばダイヤモンド砥粒からなる主砥粒
に補助砥粒を結合した研削砥石に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a grinding wheel in which auxiliary abrasive grains are bonded to main abrasive grains made of, for example, diamond abrasive grains.
ダイヤモンド砥粒やCBN砥粒をレジンなどの結合材に
よって結合した研削砥石が仰られているが、これら砥粒
を保持している結合材の耐摩れ注、耐熱性が悪いために
充分な研削性能が得゛られない。すなわち、研削作業時
における摩擦熱によって結合材が発熱し、結合材の劣化

もに表面あらさが悪く、仕上げ研削耗度が低いという欠
点もある。Grinding wheels that combine diamond abrasive grains or CBN abrasive grains with a binder such as resin are being talked about, but the binder that holds these abrasive grains has poor wear resistance and poor heat resistance, making it difficult to achieve sufficient grinding performance. I can't get it. In other words, the bonding material generates heat due to frictional heat during grinding work, causing deterioration of the bonding material and abrasive grains falling off or being destroyed, making it impossible to withstand high cutting depths (30 μm or more) and reducing grinding efficiency. In addition, since only diamond abrasive grains or CBN abrasive grains act as a grinder, the grinding wheel wears out quickly, the surface roughness is poor, and the finish abrasion level is low.

4か構成されている。The present invention will be described below based on an embodiment shown in the drawings. 1 in the diagram is diamond abrasive grain or CBN
A main abrasive grain consisting of abrasive grains, 2... is a hot-pressed silicon nitride having a grain size equal to or smaller than the main abrasive grain 1, and an auxiliary material coated with Cu or Ni with a thickness of 10 to 20 βm. It is an abrasive grain. The grinding wheel 4 is constructed by mixing 5 to 10% of the auxiliary abrasive grains 2 in a binder s made of resin bond and sintering the above together with the abrasive grains 1.

4. It has excellent abrasiveness and typical properties as shown in Table 1, causing appropriate wear and tear on the bonding material 3 while preventing the main abrasive grains 1 from falling off and breaking. . Furthermore, a gap 5 is formed between the main abrasive grains 1 and the auxiliary abrasive grains 2 due to the difference in grain size, thereby facilitating the discharge of chips generated during grinding.

。Table l Note that in the above example, 5 to 10% of hot-pressed silicon nitride was mixed into the binder 3, but the content capacity and particle size can be changed depending on the required cutting efficiency and accuracy. Although resin bond is used as the bonding material 3, other thermosetting resin materials may be used.

、従来の研削砥石と比較すると表2のとおりである。As explained above, in this invention, the main abrasive grains and the auxiliary abrasive grains made of hot-pressed silicon nitride are sintered together with a binder, so that high cutting depth grinding (30 μm% 50 μm) can be achieved.
This makes it possible to reduce the amount of wear on the whetstone, making it easier to sharpen! I
It is possible to improve l accuracy and finish grinding accuracy, and the comparison with conventional grinding wheels is as shown in Table 2.
