FIELD: chemistry.
SUBSTANCE: device comprises a blank holder on one side, a blank holder guide and blank positioner in relation to the grinding disc which can be moved up and down. The blank holder comprises rotating and longitudinal travel mechanisms; blank positioner comprises two plates with V-shaped grooves. One of the plates is hard-mounted on the platform, and the other plate can be attached to the first one by fasteners.
EFFECT: uniform surface grinding throughout the length, minimised blank deflection effect.
