A device is known for grooving according to machine JI 16X3512 providing a boring of a bore with a bore diameter which is recessed into a cone with a working part, another L-shaped reesh, a movable wedge for embossing with a 1/1 cutter and an emphasis, working honor of the cone is sewn in the shed of the rib element from the ends with the supporting part of the guiding neck and the groove in which the cutter is placed, installed with the possibility of interaction with the lateral surface of the groove.

This design 1 sends the following disadvantages

- the complexity of the design with the use of the L-shaped sweeping cutter, the execution of which has its own technologically more difficult

NOTES1

- the need to place in a limited space of the hole of the blasted digmet several components of the structure, such as a mandrel, a wedge rod, a cutter, forces these parts to be sewn to their wide dimensions in cross section, which negatively affects the rigidity of the structure;

increased consumption of incisors;

- cutting of the cutter does not occur in a straight line, but in radius, the value of which is determined by the shoulder of the cutting cutter, this can lead to a distortion of the shape and size of the boring kangwa, as well as to overwriting the side of the negative side of the cutter against the walls of the boring groove;

-the need for accurate implementation of structural elements: the cutter, the wedging part of the rod-wedge-leads to unreliability of the structure, to the possibility of jamming and jamming of the cutter in the hole of the part.

2It is also known that the device for boring grooves (see ed. Cf. V 585920), which includes a spindle assembly, the spindle of which with the cutter located in it, is mounted in an eccentric cavity of the drive shaft, has a helical groove and performs planetary rotation, is also known .

Disadvantages of the design adopted for the Crototype

-the need to expend additional effort to perform the boring operation, since the use of a fork rotating around its axis in the device leads to the appearance on the pins of the coupling, which is affected by the fork, along with the useful axial component of the cutting force and the radial component of the force, which increases with increasing angle of rotation of the fork and leads to the cost of additional efforts, as well as to minimal wear and tear of structural parts;

- low rigidity of the free end of the spindle supporting the cutter due to the presence of a radial clearance between the spindle and the walls of the stop for the cutter, which is the mandrel for installing the workpiece, as a result of which a large cantilever protrusion of the free end of the spindle with the cutter is formed, and there is no support, perception / / e
