This allows the workpiece to automatically pass through the wheels and the smooth surface is obtained. Gun drilling machine is a machine used to produce long, deep holes. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension. Special types of grinders are grinding machines made for specific types of work and operations, for example: Tool and cutter grinders. An important requirement is a good chip clearance. The grinding of a tool has two parts i.e. Surface Grinding Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The base houses the table drive mechanism and on the top of the base accurately machined guideways are provided at right angles to the table to slide on it. As the name indicates Portable that means it is not fixed at one point. In the manufacturing process grinding operation is also an important operation to make a finished product, so let's start the topic.

A grinder wheel is fitted each on both sides of the shaft of the electric motor. The application of coolants to the grinding process is important. Although there are two methods of doing a grinding operation, one is wet grinding and the second one is dry grinding. Peel grinding is often compared with hard turning where a tool is traversed along a hardened workpiece following an appropriate form. A centerless grinder is a type of cylindrical grinder which uses two rotary wheels to secure the workpiece in place. In a cylindrical grinder, both the workpiece and grinding wheel are simultaneously rotated. Grinding machine operation is also carried out for machining too hard material. Never operate grinding wheels at speeds in excess of the recommended speed. It is of two types; external and internal cylindrical grinding, an external grinder is used to remove excess material from the outer surface of the workpiece. There are two tables, a lower table, and the upper table. And at the end of the article, I will give you a PDF downloadable link so that you can download the PDF of the grinding machine as well. This operation is done for smoothening the internal surface of a hole or any cylindrical workpiece. This Welding Process was first developed in 1949 by Karl-Heinz Steigerwald who was a German physicist. An unbalanced grinding wheel produces chatter and leaves undue strain on the machine. It basically use an abrasive wheel as the cutting tool. A grinding machine consists of the following parts: It is a cast-iron casting rests on the floor and supports the other parts which are mounted on it. This blog looks just like my old one!
