CONFIGURATION OF MULTI-PURPOSE MACHINE ON BASIS OF PRINCIPLES OF PARALLEL KINEMATICS Russian patent published in 2015 - IPC B23Q1/25 B23Q5/02 

FIELD: machine building.

SUBSTANCE: machine contains a stand, three racks, a sled mounted with a possibility of movement along vertical guiding racks, a spindle mounted in the housing, three pair of rods in pairs connecting among themselves the housing and the sled by means of hinges, a table for placement of a processed detail. Meanwhile it is fitted with additional pair of rods integrated with one of the mentioned pairs of rods in such a manner that the rods ends facing towards the sled are connected with by a common hinge, and the opposite ends of these rods are connected in pairs to the housing using the hinges located symmetrically with reference to the housing axis.
