Definitions

  • the present invention relates to a roll polishing rotary grinding stone to be used for roll polishing, a roll polishing device, and a roll polishing method, using the roll polishing rotary grinding stone.
  • a roll polishing rotary grinding stone is configured to polish the surface of the roll by rotating the roll and by rotating the rotary grinding stone while bringing a polishing surface of a front end face of the rotary grinding stone having a substantially annular shape into abutment against the surface of the roll.
  • a grinding stone having a polishing function is bonded to a front end face of a rotary grinding stone body instead of an outer periphery of the body, and the polishing surface of the front end face of the rotary grinding stone that is rotating as described above is brought into abutment against the surface of the roll to polish the surface of the roll.
  • polishing is also called vertical polishing.
  • gravure printing minute recesses (gravure cells) are formed in a gravure plate-making roll (gravure cylinder) in accordance with plate making information to make a plate surface, and an ink is filled in the gravure cells and transferred to a material to be printed.
  • gravure plate-making roll gravure cylinder
  • plate making (making of a plate surface) is completed through the processes involving providing a copper-plating layer (plate material) for forming a plate surface to a surface of a hollow roll made of a metal such as aluminum or iron or a reinforced resin such as a carbon fiber reinforced resin (CFRP), forming a large number of minute recesses (gravure cells) in the copper-plating layer in accordance with plate making information by etching, and then forming, on the surface of the copper-plating layer, a surface hardening coating layer such as chromium plating for enhancing a withstand print force of the gravure plate-making roll.
  • a copper-plating layer plate material
  • CFRP carbon fiber reinforced resin
  • the gravure plate-making roll having the copper-plated layer formed thereon as described above is subjected to roll polishing through use of a rotary grinding stone.

  • the through hole 102 has an inner peripheral surface 110 that has the same diameter from the back end face 108 of the rotary grinding stone body 104 to the front end face 106 thereof. That is, the through hole 102 has a straight inner diameter.
  • the polishing surface of the roll polishing rotary grinding stone and the surface of the roll are scraped off by polishing to generate polishing debris.
  • the related-art roll polishing rotary grinding stone has a problem in that polishing debris to be generated during the polishing is accumulated in a recess being a through hole portion at the center portion of the roll polishing rotary grinding stone during the polishing of the roll, and the accumulated polishing debris is brought into contact with the surface of the roll to make the surface roughness of a surface to be processed non-uniform, with the result that it is required to frequently check and clean the through hole portion.
  • the present invention has an object to provide a roll polishing rotary grinding stone, a roll polishing device, and a roll polishing method, with which roll polishing can be stably performed without making the surface roughness of a surface to be processed non-uniform by preventing polishing debris to be generated during polishing from being accumulated in a recess at a center of a polishing surface of the roll polishing rotary grinding stone.
  • a roll polishing rotary grinding stone is a roll polishing rotary grinding stone including: a rotary grinding stone body having a rotary shaft mounted on a back end face and a polishing surface formed on a front end face; and a recess formed at a center of the front end face of the rotary grinding stone body, the roll polishing rotary grinding stone being configured to perform vertical polishing with respect to a surface of a roll by bringing the polishing surface into contact with the surface of the roll, wherein the recess is formed into a tapered recess in which an inner peripheral surface of the recess is increased in diameter from the back end face of the rotary grinding stone body toward the front end face of the rotary grinding stone body.

  • a roll polishing device is a roll polishing device including the roll polishing rotary grinding stone.
  • a roll polishing method according to the present invention is a roll polishing method, which uses the said roll polishing rotary grinding stone.
  • a remarkable effect can be obtained, which is capable of providing a roll polishing rotary grinding stone, a roll polishing device, and a roll polishing method in which roll polishing can be stably performed without making the surface roughness of a surface to be processed non-uniform by preventing polishing debris generated during the polishing from being accumulated in a recess at a center of a polishing surface of the roll polishing rotary grinding stone body.
  • FIG. 1 to FIG. 3 there are illustrated one embodiment of roll polishing rotary grinding stones 10a and 10b according to the present invention.
  • the roll polishing rotary grinding stones 10a and 10b include rotary grinding stone bodies 20a and 20b, respectively, the rotary grinding stone bodies having rotary shafts 14a and 14b mounted on back end faces 12a and 12b, respectively, and polishing surfaces 18a and 18b formed on front end faces 16a and 16b, respectively, and recesses 22a and 22b, which are formed at centers of the front end faces 16a and 16b of the rotary grinding stone bodies 20a and 20b, and are configured to perform vertical polishing with respect to a surface 26 of a roll 24 by bringing the polishing surfaces 18a and 18b into abutment against the surface 26 of the roll 24.
  • the recesses 22a and 22b are each formed into a tapered recess 30 in which the inner peripheral surface 28 of each of the recesses 22a and 22b is increased in diameter from the back end faces 12a and 12b of the rotary grinding stone bodies 20a and 20b toward the front end faces 16a and 16b thereof. That is, the recesses 22a and 22b each have a tapered inner diameter.
  • the recesses 22a and 22b are each formed into the tapered recesses 30, and hence polishing debris, which is to be generated during the polishing, and is liable to be accumulated in the recesses 22a and 22b, is automatically discharged outside due to a centrifugal force caused by rotation of the roll polishing rotary grinding stones 10a and 10b. Therefore, the polishing debris is less liable to be accumulated in the recesses 22a and 22b, with the result that roll polishing can be stably performed without making the surface roughness of the surface of the roll, which is a surface to be processed, non-uniform by preventing the polishing debris from being accumulated in the recesses 22a and 22b.
  • the polishing debris is generated when each polishing surface of the roll polishing rotary grinding stones 10a and 10b is scraped off by polishing or when the surface of the roll is scraped off by polishing.
  • tapered recess 30 have a taper angle of, for example, from 1° to 45°.

  • FIG. 1 there is illustrated an example in which the two roll polishing rotary grinding stones 10a and 10b are provided on one side of the roll 24.
  • the case in which one-side two-head polishing is performed is illustrated in the example of FIG. 1 .
  • two roll polishing rotary grinding stones may be provided on each side of the roll 24 so as to perform four-head polishing as disclosed in Patent Document 3.
  • the two roll polishing rotary grinding stones 10a and 10b illustrated in FIG. 1 can be rotated in synchronization with each other or moved in the same direction in synchronization with each other.
  • a roll polishing device including the roll polishing rotary grinding stone of the present invention is obtained by mounting the roll polishing rotary grinding stones 10a and 10b on a roll polishing device such as a known roll polishing machine for a gravure plate-making roll.
  • a roll polishing device such as a known roll polishing machine for a gravure plate-making roll.
  • the roll polishing device there are given, for example, a grinding stone polishing device described in Patent Document 3 and a grinding stone polishing device described in Patent Document 4.
  • a roll polishing method of the present invention is achieved by performing roll polishing through use of the roll polishing rotary grinding stones 10a and 10b.
  • FIG. 1 to FIGS. 3 there is illustrated a case in which a through hole is formed as each of the recesses 22a and 22b.
  • a hole that does not penetrate through a rotary grinding stone body as illustrated in FIG. 4 may be formed instead of the through hole.
  • a roll polishing rotatory grinding stone 36 includes a rotary grinding stone body 50 having a rotary shaft mounted on a back end face 40 and a polishing surface 48 formed on a front end face 38, and a recess 42 formed at a center of the front end face 38 of the rotary grinding stone body 50, and the recess 42 is formed into a tapered recess 46 in which an inner peripheral surface 44 of the recess 42 is increased in diameter from the back end face 40 of the rotary grinding stone body 50 to the front end face 38 thereof.
  • the tapered recess 46 is a hole that is merely dented and does not penetrate through the rotary grinding stone body 50.
  • the configurations other than that of the tapered recess 46 are the same as those of the roll polishing rotary grinding stone 10a.
  • the recess 42 is formed into the tapered recess 46, and hence polishing debris, which is to generated during the polishing, and is liable to be accumulated in the recess 42 is automatically discharged outside due to a centrifugal force caused by rotation of the roll polishing rotary grinding stone 36. Therefore, the polishing debris is less liable to be accumulated in the recess 42, with the result that roll polishing can be stably performed without making the surface roughness of the surface of the roll, which is a surface to be processed, non-uniform by preventing the polishing debris from being accumulated in the recess 42.
  • a hollow roll made of aluminum having a circumference of 600 mm and a surface length of 1,100 mm was loaded in a copper plating processing device, and the hollow roll was completely immersed in a plating solution in a copper plating bath, to thereby form a copper-plated layer of 40 ⁇ m at 20 A/dm 2 and 6.0 V. No nodules and pits were generated on the plated surface, and a uniform copper-plated layer serving as a base material was obtained.
  • the surface of the copper-plated layer of the roll was polished through use of a two-head polishing machine (polishing machine manufactured by Think Laboratory Co., Ltd.) having the roll polishing rotary grinding stones of the present invention illustrated in FIG. 1 to FIGS. 3 mounted thereon, to thereby form the surface of the roll into a uniform polished surface.
