As reported by Cutting Tool Engineering in their article “Grinding: A Pictorial Odyssey, part II,” the publication features a collection of electron-microscope photos and detailed captions related to grinding. The article covers various aspects such as grinding wheels, chips, dressing tools, and workpiece surfaces, providing readers with a visual understanding of these complex processes. The positive feedback from readers included comments like, “I now have a visualization of something I’ve been working with for 40 years,” “Chips! Just like in turning!” and “Those were cool.”
Dr. Jeffrey Badger, renowned for his 3-day “High Intensity Grinding Course,” emphasizes that photos often trigger the “aha moment” for attendees. This inspired him to delve deeper into grinding-related photos, offering more extensive descriptions of issues like residual tensile stresses, the impact of grit size on surface finish, and the effect of grinding scratches on tool performance and coating adhesion.
In the pictorial odyssey, several intriguing images and insights are presented:
- Figure 1: Displays broaches produced under presumably identical conditions, yet with different surface finishes. The finer finish on broach No. 1 resulted in double the cutting performance compared to broach No. 2, highlighting the importance of surface finish in grinding.
- Figure 2: Illustrates a soft material after hard grit has been pushed through it, showing the three types of grinding contact: rubbing, plowing, and cutting. Each contact type impacts material removal and heat generation differently, with aggressive grinding conditions favoring cutting over rubbing and plowing.
- Figure 3: Shows a coated High-Speed Steel (HSS) tool after sectioning. It demonstrates how sophisticated coatings require precise surface finishes on substrates. Poor surface finishes lead to coating flaking, emphasizing the need for advanced finishing techniques to ensure tool performance.
These insights are leveraged to enhance grinding techniques and technologies. By understanding the intricate details of grinding processes, superior surface finishes and tool performance are ensured. Commitment to innovation and precision makes the company a leader in the industry, capable of delivering high-quality grinding solutions for diverse applications.
