“…Conventional abrasive processes, such as grinding, lapping, polishing, and superfinishing, are still commonly used for finishing mechanical parts. Simultaneously, the production of components with increasingly complex geometries, e.g., by additive technologies, and the growing requirements from the industrial sectors make it necessary to develop new processes and tools, such as grinding with lapping kinematics using wheels with diamond or cubic boron nitride grains [1][2][3][4]. A study of the use of electroplated diamond wheels in lap-grinding, which allowed for effective machining of ceramic materials, was performed in [5][6][7][8].…”

The growing use of contemporary materials in various industrial sectors, such as aerospace, automotive, as well as the oil and gas industry, requires appropriate machining methods and tools. Currently, apart from the necessity to obtain high-dimensional and shape accuracy, the efficiency and economic aspects of the selected manufacturing process are equally important, especially when difficult-to-cut materials, such as hard and brittle ceramics, have to be machined. In the research presented in this paper, a prototype tool fabricated from polyamide powder by the SLS method was used in flat-lapping of Al2O3 ceramics, showing the promising potential and efficacy of rapid tooling and manufacturing in the area of abrasive machining. The influence of the selected input process factors, such as machining time, the type of abrasive suspension, kinematic parameters, and unit pressure, on technological effects, was analyzed. The microscopic observations of the active surface of the prototype tool showed its reinforcement with loose diamond abrasive particles (size D107), resulting in the effective material removal and improved surface finish of Al2O3 ceramic samples. The directions for further development of tools fabricated by the SLS method for applications in abrasive machining were also envisaged by the authors.
