sports terms. In many texts, attempts to cover the leisure field are severely detrimental to achieving complete coverage of tourism, simply because of lack of space. For example, in the Columbus Press World Travel Dictionary, the very first term is 'A clamp, a diving term for a connecting device between an air hose and diving cylinder'.
Thread grinding machines are used to grind threads accurately. The grinding wheel itself is shaped to the thread profile. These formed grinding wheels have one or multi threads on them. 4.6 Grinding wheel A grinding wheel is a multi-tooth cutter made up of many hard particles known as abrasives having sharp edges.

Advent of advanced grinding machines and grinding wheels has elevated the status of grinding to abrasive machining where high accuracy and surface finish as well as high material removal rate can be achieved even on an unhardened material. The bulk grinding wheel – workpiece interaction as given in Figure 2 can be divided into the following
acts as a grinding aid and helps stabilise the grinding bed in the mill. However, it also presents the risk of pre-hydration. This is where the use of vertical mills for slag grinding offers a further benefit as the mill not only grinds the material but also dries it in the process. The normally-moist slag, with an eight per cent water content,
A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
