Abstract:
1. A liquid honing method using a honing machine provided with a honing zone for subjecting a work to a liquid honing process and a washing zone for subjecting the work to which the liquid honing process was executed at the honing zone to a washing process in a housing shielded from an external air, the honing zone and the washing zone being disposed adjacently, wherein the honing machine is further provided with a partition wall for preventing an ambient gas of the honing zone from entering into the washing zone disposed between the honing zone and the washing zone in the housing, wherein the work to which the liquid honing process was executed at the honing zone is carried from the honing zone to the washing zone via a work passing opening formed in the partition wall in a state in which the work is kept immersed in a liquid in a carrying bath to subject the work to a washing process at the washing zone, wherein in the honing zone, a honing bathe having, in its inside, a honing portion for subjecting the work to the liquid honing process, a shower washing portion for subjecting the work to which the liquid honing process was executed at the honing portion to the washing process, and a carrying portion for carrying the work to which the liquid honing process was executed at the honing portion from the honing portion to the shower washing portion is disposed, wherein in the honing zone, the work is subjected to the liquid honing process at the honing portion, then carried from the honing portion to the shower washing portion with the carrying portion, then subjected to a shower washing process at the shower washing portion, thereafter carried to the washing zone, and wherein in the washing zone, the work carried to the washing zone is subjected to the shower washing process, then subjected to the scrub washing process at scrub washing portions arranged at plural stages, then subjected to the shower washing process, then subjected to the washing process by immersing the work in the washing liquid, then immersed in a high temperature liquid and then raised from the high temperature liquid to execute a dry process.
