One important aspect of a grinding wheel that can be created or altered through additives is porosity, which also contributes to the cutting characteristics of the grinding wheel. Porosity refers to the open spaces within the bond that allow room for small chips of metal and abrasive generated during the grinding process.
Disc cutting What is disc cutting? Disc cutting is a process where one tooth gap at a time is cut. Disc cutting methods are easily applied in machining centres, multi-task machines and turning centres, making it possible to machine complete components in one set-up.
Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].

Nov 15, 2012· Grinding on a Swiss offers several advantages over milling. Grinding is a continuous cutting process, which can provide a better finish than milling's interrupted cutting process, which induces vibration into the part being machined. Grinding processes operate at a much higher sfpm than milling.
The facing is done in one cut when D (the Diameter of cutter) is bigger than w (the width of job).In this case the formula of Over-Run will be: Total Time for Milling : The time for milling the surface relies on the length of job(or workpiece). In the formula of Total Time for Milling,
