The latest ICEs, hybrids (see Section 2.1 .), EVs and FCEVs all directly affect the future design and production of powertrain components. This will transform the entire production value chain, from material-conversion processes, machining to grinding Grinding is often the final step in the process/manufacturing chain, meaning that no subsequent post-grinding correction of the surface and geometry is performed. This imposes strong requirements on grinding-machine technology and on the understanding Recent developments in grinding machines ScienceDirect

As manufacturing technology advances, there is increasing awareness that grinding is a “strategic process” in that it is a critical process for the achievement of the best quality of parts and the lowest cost [1,3]. This awareness has led to the formation of specialist grinding research laboratories within a number of universitiesThe grinding process is used for both high-performance machining and surface finishing of hardened steel. In addition to the grinding parameters and the grinding fluid supply, the topography of the grinding wheel mainly determines the grinding process behavior and the grinding process result.Inventions Special Issue : Modern Grinding Technology and

This finishing process could achieve good surface finish, strict tolerances and can be applied for AM metals. Anirudh et al. [ 58 ] studied the effect of post-processing Inconel 718 obtained by EBM and then finished with either grinding, or low plasticity burnishing, or their combinations.Diamond grinding induces grinding marks and SSD in the form of crystal defects and amorphous layers . Those defects can be removed in the subsequent CMP process . As an alternative, Zhou et al proposed the chemo-mechanical-grinding (CMG) process, which combines the advantages of both grinding and polishing. The CMG is a Manufacturing technologies toward extreme precision

3.1 Introduction. Magnetic abrasive finishing (MAF), also known as magnetic grinding, was first formally presented by the Soviet engineer Kargolow in 1938 years. Since the 1960s, many Soviet scholars have studied and popularized this technology subsequently. They mainly have done a lot of research work for the preparation process Abrasive fine-finishing technology utilizes a pressure-copying principle as the material removal process (The stock removal capability of the abrasive fine-finishing is far lower than grinding, and it is limited to controlling dimensional accuracies, such as sizes, taper, roundness etc.).

Gear grinding is a hard finishing method for gears, using tools with a specific geometrical profile. It is divided into two main groups: generating grinding and profile grinding, relating to the manufacturing of the tooth flank. Furthermore, these groups can be subdivided into continuous and discontinuous processes (DIN 8589).Classification of abrasive finishing "Reprinted from CIRP Annals-Manufacturing Technology, 65/2, Fukuo Hashimoto, Hitomi Yamaguchi, Peter Krajnik, Konrad Wegener, Rahul Chaudhari, Hans-Werner(PDF) Finishing ResearchGate

Grinding is an abrasive machining process that uses a grinding wheel or abrasive belt as the cutting tool. It is commonly used to remove material from a workpiece, to produce a smooth finish on the surface of the workpiece, or to remove burrs from the surface. Grinding can be performed wet or dry, and can be performed on a variety of “Creep-feed grinding is a process that can deliver more than you realize,” Wiss says. With creep-feed grinding, manufacturers can take larger depths of cut than they can with traditional surface grinding. Even added to a slow traverse rate, the material removal rate (MRR) that can be achieved is much higher than that of finish grinding.How Advanced Grinding Technology Leverages Capabilities Beyond Grinding

High quality, highly efficient finishing processes are required for finishing difficult-to-machine materials. Magnetic abrasive finishing (MAF) process is a finishing method that can obtain a high accuracy surface using fine magnetic particles and abrasive particles, but has poor finishing efficiency. On the contrary, fixed abrasive polishing The state-of-the-art wafer grinding technology aims to obtain low damage and high-quality surface at high efficiency so that the wafer manufacturing process can be shifted from grinding to CMP directly. a two-step EDG process, rough grinding followed by finishing, is necessary.
