METHOD FOR SURFACE HARDENING OF PARTS Russian patent published in 1999 - IPC

FIELD: part surface hardening at process of working them. SUBSTANCE: method comprises steps of honing worked surface by means of two groups of deforming members. Main group is in the form of set of grinding blocks. Each member of additional group is in the form of set of indenters with spherical working surface. Indenters act upon worked surface and simultaneously cutting fluid with additive is applied onto surface after working it by means of main group of deforming members. EFFECT: enhanced quality of surface hardening at simultaneous precise working of part surface. 1 dwg
