FIELD: process engineering.
SUBSTANCE: invention relates to abrasive treatment and can be used in hole cylindrical surface honing. Honing sticks are revolved and reciprocate, their rotational speed being varied. Rotational speed of said sticks is increased with sticks moving axially from reverse point nearby one edge of processed hole to reverse point nearby opposite edge and decreased with honing sticks moving in opposite direction. Then honing sticks make one rotation stroke without speed variation.
EFFECT: higher accuracy and efficiency due to increased removal of rough allowance nearby hole edges.
