Problems solved by technology

[0010] However, it is not necessarily possible to properly judge the replacement timing of the trimming plate by the above-mentioned methods such as visual inspection.
If the support plate is ground by the grinding wheel using a dressing plate worn to the limit of its thickness without replacement, the grinding wheel may be damaged

Embodiment Construction

[0027] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 (A) is a perspective view of the dressing tool 2 of the first embodiment, figure 1 (B) is A-A sectional drawing of the dressing tool 2 of 1st Embodiment.

[0028] Such as figure 1 As shown in (A), the dressing tool 2 of the first embodiment has a flat disc-shaped dressing plate (dressing portion) 4 . In addition, the shape of the trimming plate 4 is not limited to a disc shape. The shape of the trimming plate 4 may be a rectangular plate shape.

[0029] The front surface 6a of the support plate (support part) 6 which supports the trim board 4 is bonded to the back surface 4b of the trim board 4. As shown in FIG. The support plate 6 is formed in a disk shape having a larger diameter than the trimming plate 4 so as to be able to support the entire trimming plate 4 . The support plate 6 is formed of resin, for example.

[0030] The dressing plate 4 is formed u...

Abstract

Provided is a dressing tool capable of appropriately determining whether or not a dressing plate is worn to a thickness of a use limit. The dressing tool for dressing an annular array of grinding tones disposed on a surface of a grinding wheel includes a dressing board for dressing the grinding stones and a support plate supporting a reverse side of the dressing board. The reverse side of the dressing board has a recess defined therein that has a depth terminating short of s face side of the dressing board that is opposite the reverse side thereof and corresponding to a usage-limit thickness of the dressing board.

Description

technical field [0001] The invention relates to a dressing tool for dressing an abrasive tool for grinding grinding wheels. Background technique [0002] As a processing method in the case of dividing a wafer having a plurality of devices formed on the front side into chips corresponding to each device, for example, there is a method in which the back side of the wafer is ground, and then the wafer is ground by a cutting tool. Cut and divide. [0003] Grinding of the wafer is performed, for example, by a grinding apparatus equipped with a grinding wheel having a grinding wheel (grinding wheel) for grinding. A wafer is held by a holding table of a grinding apparatus, and a rotating grinding wheel is pressed against a surface to be processed of the wafer to grind the wafer (for example, refer to Patent Document 1). [0004] The above-mentioned grinding wheel is formed by mixing abrasive grains such as diamond or cBN (cubic boronnitride, cubic boron nitride) into a bonding ma...
