Investigating adhesion wear on belt and its effects on dry belt finishing

Abstract

Adhesion wear on abrasive belt sometimes occurs as an abnormal abrasion way because of an improper selecting on working conditions during the belt finishing. In this paper, the forming process of the adhesion wear and its effects on the finished surface is investigated through a series of experiments. The results reveal that the applied pressure and the belt feed rate are supposed to be the two sensitive variables for forming the adhesion wear. A certain amount of accumulated chips is a trigger to cause adhesion wear initially, and then, the sufficient heat accumulation becomes the main factor for the following adhesion wear. Thus, shortening the finishing duration, decreasing applied pressure, rotating speed and introducing cooling/lubrication system are recommended to avoid adhesion wear. The belt finishing process with adhesion presents a potential to further decrease surface roughness by 30% maximum, improve bearing characteristics and obtain equivalently high compressive residual stresses; however, this merit has to go with the sacrifice of belt's cutting ability.

Superfinishing with Abrasive Films Featuring Discontinuous Surfaces

“…This method offers a controlled and precise approach to achieving desired surface characteristics while minimizing the risk of contamination. By employing abrasive films, manufacturers can optimize their processes by ensuring consistent and high-quality surface finishes [12][13][14]. The singleuse nature of abrasive films further enhances reliability, as it eliminates the potential for cross-contamination and ensures that each surface finishing operation is performed with a Materials 2024, 17, 1704 2 of 17 fresh tool [15,16].…”

Effects of Pressure Rollers with Variable Compliance in the Microfinishing Process Utilizing Abrasive Films

“…It involves the utilization of abrasive films, particularly microfinishing film, to refine surfaces to micro-inch or even nanometer-level finishes [22]. Microfinishing film comprises a backing material coated with precisely graded abrasive particles (Figure 2) [23]. This abrasive film is adept at removing imperfections such as scratches, tool marks, and surface irregularities, thereby yielding a smooth and uniform surface texture [24].…”

Evaluation of the Surface Topography of Microfinishing Abrasive Films in Relation to Their Machining Capability of Nimonic 80A Superalloy

“…In the realm of microabrasive machining, exemplified by precision grinding and microfinishing, the depth of the tool's intrusion into the workpiece material remains markedly shallower than the curvature of its edges, akin to the minute elevations present within the microcutting zone [15][16][17]. The inherent variability in the penetration of abrasive grains into the workpiece material stands as an undesirable yet inescapable trait of microcutting [18,19]. A contemporary approach to refining technical surfaces through microfinishing, employing abrasive films, has emerged as a paramount technique for refining external cylindrical and conical surfaces alongside flat end faces [20,21].…”
