METHOD OF FACE-HARDENED PROCESSING OF LONG-MEASURING OF CYLINDERS WITH FILLETS Russian patent published in 2009 - IPC B24B39/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to metal forming field, particularly to processing by surface plastic deformation, and provided for plastic deformation of long-measuring cylinders with fillets. It is impacted rotation to treated detail and it is implemented running of its cylindrical and fillet sections by means of providing of knurling head with deformation elements in the form of rollers of sliding feeding lengthwise treated surface of the detail. Face-hardened processing is implemented simultaneously for two details, installed parallel on two positions, each of which contains one knurling head. Running of cylindrical and fillet sections of each detail is implemented from the middle of its cylindrical section in the direction to fillet section. At first, at the first position, it is treated half of the detail, it is displaced the last and the second position, on which it is treated its second half with formation of crossover of the hardened area in the middle of cylindrical section of detail.

EFFECT: consequently it is increased productivity of face-hardened treatment of details.
