面でワーク１５端面の研削を行う。2. Description of the Related Art Conventionally, surface grinders include a grinding machine in which an end surface of a rotating grinding wheel is brought into contact with a work, and a grinding machine for grinding a work on a peripheral surface of the grinding wheel.
In general, in the former, a vertical axis grindstone head in which the grinding wheel axis is held vertically with respect to the horizontal worktable is provided on the column so as to be vertically movable, and in the latter, the grinding wheel axis is held parallel to the worktable, that is, horizontally. A horizontal wheel head is used. For example, when a thin plate such as a blade of a papermaking machine is wound in a coil shape and its coil end surface is ground, the coiled work 15 is fixed on a rotating circular table 17 as shown in FIG. The lower end surface of the grinding wheel 20 of the vertical grinding wheel head 19 is brought into contact with the work 15 and rotated to grind the end surface of the work. In the case of a horizontal grinding wheel head, the grinding wheel shaft 21 is held horizontally as shown in FIG.

研削し直さなければならないという問題があった。In the end face grinding of a coil-shaped work by winding a thin plate such as a blade of a papermaking machine, a large grinding allowance can be taken, so that a grinding machine generally using a vertical grinding wheel head as shown in FIG. However, in this method, the work is cut off at one end surface of the grinding wheel, so that the scratches 23 having a streak shape as shown in FIG. It is necessary to perform finish grinding with a horizontal axis grindstone head in order to eliminate such pit-like grinding marks, but performing rough grinding and finish grinding with two different grinding machines is inefficient, and After performing rough grinding with a vertical grinding wheel head type grinder, remove the work and transfer it to another horizontal grinding wheel head type grinding machine, the work wound up in a coil shape may be broken, and once the work is broken There is a problem that it is difficult to return to the original state, and that the uneven surface must be ground again.
