The purpose of the research work is to increase the efficiency of the tool system for dimensional cutting during operation (SPP) for honing holes, in particular holes with discontinuous surfaces and small diameter holes. Ensuring high accuracy and stability of the process of processing holes with discontinuous surfaces is achieved by using an improved design of the honing tool, taking into account the conditions of periodic loss of contact of the cutting grains with the surface of the workpiece Processing of small diameter holes (less than 10 mm) is achieved by reducing the mass and dimensions of the tool with increasing its rigidity and installation accuracy through the use of miniature honing heads with microfeed drives; reducing vibrations and radial runout through precision balancing of the tool system; integration of elastic compensation mechanisms that ensure stable pressing of abrasive elements within the narrow limits of the hole. The introduction of combined rotation schemes (simultaneous rotation of the tool and workpiece) allows to reduce the influence of the discontinuity of the hole on the stability of the shape formation, as well as: to improve the uniformity of material removal along the length of the hole; to minimize local overload zones on abrasive grains; to reduce the risk of formation of zones with residual stresses. The lubrication and cooling conditions are stabilized by optimizing the supply of cooling and lubricating fluids (CLF) under pressure to the contact zone of the tool with the part, which allows to reduce temperature deformations; removal of wear products (abrasive and particles of the processed material) from the cutting zone prevents clogging and improves the quality of processing Product Description popup.authors Maslianikov Vitalii Yu. popup.nrat_date 2025-07-10 Close
