Study on design and performance of metal-bonded diamond grinding
Grinding performance-oriented proactive design is hard to realize by conventional hot-pressing sintered grinding wheel, because the internal micro-structure of grinding wheel is relativelyAssociate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece’s surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.Machining 101: What is Grinding? Modern Machine Shop

Application of a pressurized internal cooling method in grinding
Influenced by the structure and manufacturing process of the internal cooling grinding wheel, when the outlet of the channel is located on the inner edge, the flow of coolant will be blocked due to the height difference between the outlet position and the abrasive surface, resulting in less effective flow through the grinding area, which is not Nevertheless, it was impossible to control the internal structure of the tools as porous metal-bonded grinding wheels have several advantages compared with dense metal-bonded tools.
