The invention relates to mechanical engineering and can be used to process internal cylindrical surfaces.

The aim of the invention is to increase the productivity of processing by increasing the intensity of the correction form.

The drawing shows the honing head, a longitudinal section.

The honing head includes a body 1, inside which there is an expanding cone 2. On pushers 3, separators 4 are installed with rollers 5, which contact the bar holders with abrasive bars 7. On the bar holders there are ring springs 8, and in grooves the ends are rings 9. In the axial direction the bar holders are tightened by elastic elements 10 and P.

For the processing of the product, the expanding cone 2 is associated with a working axial movement, which expands radially pushers 3 with bar holders with abrasive sticks 7. During machining under pressure of axial component cutting force bar holders in contact with separators 4 and rollers 5 are displaced axial direction relative to the housing 1 honing head. Installed in the grooves bar holders b with radial

with a gap of the ring 9 ensure their simultaneous axial movement. The magnitude of the axial movement of the bar holders b with the bars 7 is limited by the elastic elements 10 and P. At the end of the process, the ring springs 8 return the bar holders to their original position.

The described design of the homing head makes it possible to increase the intensity of correcting the error of the geometric shape, to increase the productivity of the homing process, because the installation with a radial clearance of the rings has the rigidity of elastic elements, which allows to overcome friction of individual bar holders and ensure their simultaneous displacement.
