時に研削加工するように構成したものである。2. Description of the Related Art As shown in FIG. 4, for example, the double-head surface grinder has a main body frame 1 with a pair of quills 2 and 3 disposed coaxially and facing each other, and a worm gear driven by an appropriate drive mechanism (not shown). Both quills 2,
3 rotatably supports grindstone shafts 6 and 7 which are rotated by motors 4 and 5, respectively, and both grindstone shafts 6,
Grinding wheels 8 and 9 are mounted on corresponding shaft ends of the grinding wheels 7, respectively, with their grinding surfaces facing each other, and a carrier plate 10 is provided between the grinding wheels 8 and 9, which is rotated in a plane orthogonal to the grinding wheel axis. The carrier plate 1 is arranged so that its outer peripheral edge overlaps the upper and lower grinding wheels 8 and 9, and the carrier plate 1 is arranged between the upper and lower grinding wheels 8 and 9 that are driven to rotate.
0, a workpiece is carried in and both sides of the workpiece are ground simultaneously.

ツシングを行う必要がある。 By the way, in the grinding process using the double-headed surface grinder, if the grinding wheels 8, 9 are used for a long period of time or the grinding conditions of the grinding wheels 8, 9 are inappropriate, the grinding wheels 8, 9 may
The grinding surface becomes clogged or clogged, resulting in poor sharpness, and grinding cracks and grinding burns occur on the finished surface. Therefore, when the grinding surfaces of the grinding wheels 8 and 9 become clogged or clogged, the worn abrasive grains on the surface layer of the grinding surfaces and the chips clogged in the gaps or pores between the abrasive grains are removed, and the grinding surfaces are removed. It is necessary to perform dressing to expose new abrasive grains.

行う必要がある。 In addition, the abrasive grains on the grinding surfaces of the grinding wheels 8 and 9 gradually fall off during the grinding process, and the shape of the grinding surfaces gradually becomes different from the initial shape. It is necessary to perform truing to reshape the shape.

にしたものである。 Conventionally, such dressing and truing have been performed using, for example, a diamond dresser 11 as shown in FIGS. 4 and 5. This diamond dresser 11 has diamond chips 13, 13 protruding from the top and bottom of the tip of a dressing arm 12, which is rotatably mounted on a main body frame 1 in a plane perpendicular to the axis of the grinding wheel. Move the diamond chip 13,
By inserting the grinding wheel 13 between the upper and lower grinding wheels 8 and 9 which are rotationally driven and moving it in the radial direction of the upper and lower grinding wheels 8 and 9, the surface layers of the grinding surfaces of the upper and lower grinding wheels 8 and 9 are scraped off to perform dressing or truing. This is how it was done.

No. 167158 proposes a dressing device for a double-head surface grinder that solves the above problems. As shown in FIG. 6, this dressing device is driven to rotate about its own axis, and a disk-shaped grindstone 15 is attached to a spindle 14 that makes linear reciprocating motion in the direction of the axis. By inserting it between the rotationally driven upper and lower grinding wheels 8 and 9 and moving it in the radial direction of the upper and lower grinding wheels 8 and 9, the surface layer of the grinding surfaces of the upper and lower grinding wheels 8 and 9 is scraped off to perform dressing or truing. This is what I did.

が、充分満足できるものではなかつた。Problems to be Solved by the Invention Incidentally, in the above-mentioned dressing device, since dressing or truing of the upper and lower grinding wheels 8 and 9 is performed by the grinding wheel 5 through line contact with each other, dressing or truing using the conventional diamond dresser 11 is not possible. Although the work efficiency was slightly improved compared to the above, it was not completely satisfactory.
また、砥石８，９の研削面上で周速度差がある

下砥石８，９の研削面の内径側に進むにつれて、
上下砥石８，９の研削面上の周速度が遅くなる為
に上下砥石８，９の砥粒に抵抗がかかり必要以上
に削り落とされるからである。 Furthermore, because there is a difference in circumferential speed on the grinding surfaces of the grinding wheels 8 and 9, uniform dressing or truing cannot be performed on the entire grinding surface of the grinding wheels 8 and 9, and even if dressing or truing is performed, the accuracy cannot be improved. There were many cases where there was no such thing. For example, the grinding surfaces of the upper and lower grinding wheels 8 and 9 after dressing or truing should be planes perpendicular to the grinding wheel axis as shown in FIG. 6, but instead become inclined surfaces with respect to the grinding wheel axis as shown in FIG. . This is because as the grindstone 15 advances toward the inner diameter side of the grinding surfaces of the upper and lower grindstones 8 and 9,
This is because the circumferential speed of the grinding surfaces of the upper and lower grindstones 8 and 9 becomes slower, which creates resistance to the abrasive grains of the upper and lower grindstones and causes them to be ground off more than necessary.

欠点がある。 Furthermore, in the above dressing device, the type of grindstone 5 is different for dressing and truing (GC-based and WA-based grindstones are used for dressing, and a diamond grindstone is used for truing), so the grindstone 15 must be replaced each time. This has the disadvantage that it takes time to change setups, making the work extremely difficult.
