PROCESSING OF DEEP SURFACES WITH COMBINED TREATMENT

When broaching deep openings, especially long-length casing of hydraulic cylinders, practically

makes it cutting with two-sided shaving grooves of normal length due to insufficient strength of the tool

for tension. For the forced separation of the shear layer at the stroke, it is proposed to create, on the

working surface of the part, full regular macroreliefs with the help of deformation and cutting stretching.

The technological properties of the full control of the macro-relief will allow the traditional chip-split

scrubs to be abandoned on the rough, semi-roughing and finishing blades of the drag, allowing for the

entire length of the cutting loop to be put into operation. The study of the formation of complete regular

macroreliefs has shown that they can also be used effectively in solving technological problems, in

particular for the forced separation of the let down into cutting, fulfilling its basic service functions. It has

been established that the free formation of a cutting roll when it is stretched by a tool with a flat front

surface affects the thickness of the cut, the properties of the processing material, as well as the degree of

deformation strengthening. The dimensions of the cutting roll and the ability of the latter to form a flat or

spatial spiral is of great importance for those cutting processes whose kinematics does not allow for the

free evacuation of chips from the chipping zone. First of all it concerns internal cutting, since the

diameter of the cutting roll is the determining factor for the permissible degree of filling of the cutting

groove.

Key words: broaching, deformation, macrorelief, shavings, relief formation.
