FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used in designing and constructing spark-erosion machines. Proposed machine comprises bed, column, transverse carriages, working head with sliding spindle, electric holder, table mounted at said bed that forms a clearance between column face surface and rear surface, bath with rear wall arranged in said clearance to displace vertically therein. Besides machine includes structural part mounted at said column to prop table support, while transverse carriages are mounted at structural part outer horizontal surface to support rotary vertical knee at front surface thereof mounted is working head with spindle for angular positioning.
EFFECT: simplified design and operation, higher stiffness.
