FIELD: technological processes.
SUBSTANCE: invention relates to abrasive processing and can be used in machining large-sized complex-shaped ceramic articles. A mandrel with fixation assemblies is used, which is installed on a lathe. Surface layer of mixture consisting of epoxy resin with quartz powder introduced into it in amount of 25–55 wt% is applied on assemblies of mandrel fixation. After the mixture layer hardening, processing of the fixation units by the diamond wheel is carried out to the specified dimensions. Large-size article is installed on mandrel fixation assemblies and surface of ceramic product is treated to preset size by means of said diamond wheel.
EFFECT: higher quality of machining of large-size complex-shaped ceramic articles.
