2. Description of the Related Art Generally, in grinding work with a processing machine such as a grinder, when a grindstone is used to grind an angled object, a long object or a large workpiece, the grindstone is used for a long time. Dressing may not be possible and it is necessary to dress regularly. In the past, when dressing, the work piece was removed from the machine body, dressing was performed, and then the work piece was attached to the machine body again. Since it also needs to be cleaned, extra time is required for attaching and detaching the workpiece, cleaning, etc., and the operating time of the processing machine is greatly reduced.

In order to solve such a problem,
Recently, in the case of mounting a magnet chuck on the work table and mounting a magnetic work piece on the chuck to perform grinding, a square columnar dresser block is mounted on the side of the magnet chuck. In some cases, the dresser supported by the dresser block is projected and retracted with respect to the upper surface level of the magnet chuck.

In this case, when dressing of a grindstone is required, the work table of the processing machine body is moved to position the dresser block below the grindstone, and the dresser of the dresser block is projected above the upper surface level of the magnet chuck. And dressing immediately,
Dressing can be performed easily with the work piece attached to the work table, and grinding accuracy can be maintained at a high level at all times without shortening the operating time of the processing machine. 153048).

However, in such a conventional dressing device for grinding, a square columnar dresser block is mounted on the side portion of the magnet chuck, and the dresser supported by this dresser block is provided. Since it was designed to appear and disappear with respect to the upper surface of the magnet chuck, when there is an angle on the work table, etc.,
The dresser may not hit the work piece in parallel and may not reach the work piece.As a result, the work piece must be removed from the magnetic chuck and dressing must be performed, reducing the operating time of the processing machine. There was a problem that it would end up. That is, the conventional one is suitable for a surface grinder and cannot be applied to a work table having an angle.

Further, in the case of attaching to a work piece and performing dressing, if the shape of the work piece has a complicated shape, the work piece cannot be attached to the work piece, and the work piece needs to be removed for dressing. Therefore, the operating time of the processing machine has been shortened as described above. Therefore, the present invention provides a dressing device for grinding that can perform dressing of a grindstone without removing a work piece from a work table of a main body of a processing machine and can prevent a reduction in operating time of the processing machine. The purpose is to do.
