BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical plane parallel plane honing grinder and a lapping machine mainly used at a wheel rotation speed of 100 rpm or less.
The present invention relates to a superabrasive resin bond wheel that can be effectively used even in ordinary grinding.

2. Description of the Related Art As a work material of this type of superabrasive resin bond wheel, cermets, carbides, ceramics, and the like, which are difficult-to-cut materials, are usually considered.

[0003] These difficult-to-cut materials are very difficult to machine even in the usual constant-incision grinding, and the damage to the polished surface is large. In addition, since the swarf at the time of grinding is a minute swarf, with the progress of grinding, which is a characteristic of the resin bond wheel, we hope that the swarf will scrape off the bond and the proper breaking by abrasive crushing, so-called autogenous action It is difficult.

In addition, when used for a parallel plane honing grinder and lapping machine with a vertical axis, the grinding is performed under a constant pressure, and the peripheral speed is low.
Before effective use of the entire grain, wear, crush,
Since dropouts are likely to be caused, it is difficult for proper eye closing to proceed. Therefore, the grinding performance is greatly affected by the degree of progress of appropriate cutting by sharpening before machining, that is, sharpening. This is inferred from the fact that wear at the time of dressing has a greater effect on the life of the wheel than wear at the time of grinding.

【0005】このように、この加工方式にとって目立て

[0006] The performance of the resin bond depends on the raw materials used and the compounding ratio thereof. Raw materials for resin bonds are roughly divided into resins and fillers, and their selection is very important for the required performance improvement.

In selecting a resin, epoxy resin, polyvinyl alcohol, polyurethane, unsaturated polyester, and the like have relatively low strength and the change of the abrasive layer is good, but the heat resistance is lower than that of the phenol resin. Therefore, there is a disadvantage that abnormal wear and burn occur during grinding. The imide-based resin has a relatively low flexural modulus, and particularly often has a low hardness, which often leads to embedding of abrasive grains. If a filler is added to improve this point, the strength becomes too high and conspicuousness is poor. Become.

[0008] A phenolic resin is widely used as a bonding resin for a superabrasive resin bond wheel, and a large amount of a filler is added to improve abrasive holding power and hardness. However, this large amount of filler hinders proper eye-opening. In addition, in order to reduce bending strength for the purpose of proper bending, it is also necessary to reduce the amount of filler added or to add a solid lubricant. As a result, the biting force into the work material during grinding is reduced.

The bonding resin itself does not soften or deteriorate due to heat generated during grinding, and the resulting grinding wheel has the advantage that its strength and performance can be maintained even after long use. However, since this resin has a low hardness and a low elastic modulus, it causes embedding of abrasive grains.

When grinding difficult-to-cut materials with high efficiency in this machining method, the physical property of the bond is that the hardness of the bond is high in order for the abrasive grains to bite into the work material. This is a mandatory condition. However, if a large amount of filler is added in order to obtain physical properties of high hardness, strength and abrasion resistance are unnecessarily improved, which hinders proper progress of the eye contact, and conversely reduces grinding performance. Inconsistency occurs.

The heat-molded product of the obtained bond can be easily dressed due to the low-strength physical properties of DAIP and DATP, and the proper bonding proceeds. In addition, the heat resistance and water resistance of DAIP and DATP and the blending of chromic oxide have a Rockwell hardness of Hrf 91 or more, so that the balance between the protrusion of abrasive grains and the wear during dressing can be balanced, and grinding of difficult-to-cut materials. In this case, the abrasive grains are prevented from being buried, and the penetration into difficult-to-cut materials is ensured. By effectively utilizing the abrasive grains by these interactions, an appropriate grain is advanced and a superabrasive resin bond wheel capable of performing high-efficiency processing is obtained.
