ていた。2. Description of the Related Art Conventionally, various castings such as cast iron castings, steel castings, bronze castings, brass castings, aluminum alloy castings, magnesium alloy castings, and deburring of MMCs and the like are mainly used for deburring diamonds, CBNs, and the like. This was an electrodeposited superabrasive grain wheel in which superabrasive grains were fixed to a metal base metal by nickel plating. As long as the base metal can be manufactured, the electrodeposited superabrasive wheel can easily fix the superabrasive grains on the surface thereof by nickel deposited by electroplating or chemical plating, and the manufacturing period is short and the cost is low. However, when used for deburring of the various materials described above, the material removal rate may be high, so that not only efficiency often decreases due to clogging, but also the corner portion of the superabrasive grain layer. Short life due to superabrasives falling off and peeling of the plating layer has been a problem.

That is, the present invention provides a superabrasive wheel having excellent material removal ability and a long life as compared with the conventional electrodeposited superabrasive wheel, and in particular, capable of performing deburring of various castings and MMC with high efficiency. It is.

A super abrasive grain wheel, wherein the super abrasive layer has a flat portion 2a perpendicular to the wheel rotation axis C, and a tapered portion 2b continuous with the flat portion and inclined with respect to the wheel rotation axis, The taper portion angle θ is set to 5 degrees to 60 degrees.

めほとんど用いられないのでこれを上限とした。[0005] The average particle size of the superabrasive particles is such that the material removal rate is 5 mm.
This is because a minimum of 100 μm is required to secure a chip pocket required for high-efficiency grinding of 3 / mm / sec or more. This is set as the upper limit because it is hardly used because of high cost.

For example, when processing mild steel, an aluminum alloy, a copper alloy, MMC, or the like, it is more preferable that at least a gap of 50 μm or more is provided and the distribution is substantially uniform. If there is a portion where the abrasive grains are partially agglomerated on the grinding surface, clogging is apt to occur at that portion, and the clogging is spread over the entire surface, which is not preferable.

In charge of roughing in the taper part and finishing in the flat part,
It is intended that the processing can be completed in one pass. Since the tapered portion shares almost all the processing in the portion, the amount of material removed per unit area of the superabrasive layer is extremely large, and a large grinding resistance is received. In order to bear this large grinding resistance in as large an area as possible, the taper angle θ is set to 5 degrees to 60 degrees. When deburring is performed in one pass for general use, the depth of cut is large, so that θ is often set to 10 degrees to 45 degrees.

It is characterized by being any one of the r-based brazing filler metals. An Ag-Cu-Ti-based brazing material having a low brazing temperature and a high fluidity is preferable, and has excellent wettability not only with steel used as a base metal but also with diamond in particular and a high fixing force. Although a brazing filler metal is optimal, a Ni-Cr-based brazing filler metal or a Co-Ni-Cr-based brazing filler metal can also be used. In order to manufacture using a brazing material, a paste-like brazing material is preferably used. Here, the paste-like brazing material is generally obtained by kneading a powder of the brazing material with a binder and has an appropriate viscosity, so that it is easy to set superabrasive grains. A paste-type brazing material is applied to the grinding action surface of the base metal, and superabrasive grains are arranged on it by a handset or a machine.When the brazing material is dried and the superabrasive grains do not shift, it is placed in the furnace. It is put and heated to melt the brazing material and then cooled to further fix the superabrasive grains.

It is characterized by the following. Depending on the type of the workpiece, the cutting powder may erode the brazing material layer and cause the superabrasive grains to fall off. In the case where the wear resistance is not sufficient with the brazing material layer alone, the surface of the brazing material is coated with a hard coating such as nickel plating or chromium plating so as to minimize abrasion due to chips or the like. It is preferable to maintain the super abrasive grain holding power.

% Diamond, CBN, WC, WC-Co, Si
One or two or more of C and Al 2 O 3 are mixed and contained in an amount of 5 to 50% by volume based on the volume of the brazing material. When the Ag-Cu-Ti-based activation brazing material is used for the brazing material for fixing the superabrasive grains,
In the case where the brazing material is eroded by the cutting powder and the superabrasive grains easily fall off, the brazing material itself may be given wear resistance.
Specifically, as hard particles in the brazing material, diamond, CBN, WC, WC having a diameter of 1 to 30% of the average particle diameter of the superabrasives are used.
-Co, SiC, of Al 2 O 3, were mixed and the one or more kinds, may be contained 5 to 50% by volume based on the brazing material volume. If the particle size of the hard particles exceeds 30%, the bonding strength of the brazing material is reduced, which is not preferable.
If the content of the hard particles is less than 5% by volume, the effect of adding the hard particles cannot be obtained, and if the content exceeds 50% by volume, the bonding strength of the brazing material is reduced.
