FIELD: technological processes.

SUBSTANCE: invention relates to mechanical methods of processing monocrystalline ingots. Method of connecting and fixing mono crystals involves the positioning of several mono crystals, their orientation in a certain way and fixation of mono crystals with each other by means of adhesive, whereupon pre-selection of the necessary number of monocrystalline ingots is carried out, and then carry out orientation of the ends of the selected ingots with required tolerance and removal of base pre-cut with the length of 18-20 mm, whereupon glue mono crystal ingots using device to connect and fix mono crystals as follows: apply adhesive material onto previously degreased end of the mono crystal ingot, mount ingot with preliminary base cut on the base plane 1 of the device while pressing the ingot with clean end against the fixed stop 4 and ingot generant to the surface of the side guard 2, mount next ingot with preliminary base cut on the base plane 1 of the device firmly against the end of the previous ingot, and rotating the knob 7 of the pressing screw 6, press ingots against each other by means of movable stop 5, repeat these operations until the stack of required length is obtained, maintain stack in the device until complete curing of the adhesive material using two-component, colorless epoxy rubber adhesive, and then carry out calibration of the stack to the desired diameter and detach the main base cut, control orientation of the base cut and perpendicularity of ends to the generate. Alternatively, the method of connection and fixation of monocrystals can be implemented without removal of preliminary base cut using device for applying general auxiliary line.

EFFECT: simplified connection and fixation of monocrystals, reduced time costs, higher accuracy of alignment of crystallographic axes of monocrystal ingots.
