The dependence of the performance of the process of finishing vibration processing on the shape of the abrasive tool (granules)

Abstract

The article presents the results of experimental studies of the influence of polymer abrasive granules shape on the surface roughness formation and metal removal during vibrational finishing and hardening treatment (VFHT). As is known, surface roughness and the amount of metal removal are affected by a number of factors: binder material, material and granularity of the abrasive, technological lubricant-coolant medium (LCM) type, loading mass, initial roughness, etc. Processing was carried out for 120 min on a UVG-4x10 vibrating machine, with a working chamber volume of 10 dm3. Metal removal Q (grams) and surface roughness Ra (μm) were measured using an AD-200 analytical balance and an SJ-210 profilometer. The results presented show that polymer abrasive granules have high cutting ability, the intensity of which depends on the shape of the granules.
