DO be sure wheel hole or threads fit machine arbor properly and that the flanges are clean, flat, undamaged, and the proper type. DO run wheel in a protected area for one minute before grinding. DO wear ANSI Z87+ safety glasses and additional eye and face protection, if required.
As my previous article of Grinding Machine, I told, grinding is an important operation in manufacturing industry to get a final product, so for that, we need to know about the grinding wheel and its properties so that we easily choose a right wheel for the right material.. I assumed that you already have a brief idea about Grinding Machine. Don't worry! if you not learned yet you can check ...
a CNC machine. The main difference is that instead of cranking handles to position a slide to a certain point, the dimension is stored in the memory of the machine control once. The control will then move the machine to these positions each time the program is run. In order to operate and program a CNC controlled machine, a basic understanding

Weld symbols are used to indicate the welding processes used in metal joining operations, whether the weld is localized or "all around", whether it is a shop or field weld, and the contour of welds. These basic weld symbols are summarized below and illustrated in figure 3 …
This part is related to the contour section. Where this symbol is designed to specify which process is used to achieve the desired contour. The common process for finishing the weld surface is grinding (G), chipping (C), and machining (C). See: Type of Welding Joints. The Tail Welding Symbol.
