Ensuring the Quality of Conical Mating Surfaces Processing by Diamond Honing

Diamond honing is the dimensional treatment of various surfaces using honing heads that rotate and reciprocate while simultaneously feeding stones in a radial direction. The high durability of diamond stones, low temperatures in the cutting zone, and low cutting forces can improve the accuracy and productivity of processing, reduce the roughness of the machined surface, apply active control, automate the honing process and increase the durability of the machine parts and mechanisms. In contrast to the processing of cylindrical surfaces, honing of tapered holes takes place with a constant change in the contact area of the tool with the machined surface, which leads to uneven removal of the allowance. This work aims to ensure the quality of tapered surface processing by honing. The experiments were carried out on industrial equipment. Considering the influence of contact pressures on the surface quality, the correction factor of the generatrix of the conical hole was experimentally determined, and the dependences of the change in the depth of penetration of the cutting grains were obtained.
