Each general purpose conventional machine tool is designed and used for a set of specific machining work on jobs of limited range of shape and size. But often some unusual work also need to be done in a specific machine tools, e.g. milling in a lathe, tapping in a drilling machine, gear teeth cutting in shaping machine and so on.
Fig. Types of surface grinding machines Tool and cutter grinder In grinding tools by hand a bench or pedastal type of grinder is used. The tool is hand held and moved across the face of the wheel continually to avoid excessive grinding in one spot. For sharpening miscellananeus cutters a universal type grinder is used. 2. Types of Grinding wheels
There are mostly four types of grinding processes used in industries and these are as mentioned here, we will discuss each type of grinding process in details here. Cylindrical grinding Object will rotate around one axis and the surfaces of object which need to be grinded will be in concentric with that axis around which workpiece will rotate.

Gears of various type, size and material are widely used in several machines and systems requiring positive and stepped drive. The major applications are : • Speed gear box, feed gear box and some other kinematic units of machine tools • Speed drives in textile, jute and similar machineries • Gear boxes of automobiles
Working principle of Grinding Machine: The working principle of a grinding machine is quite easier to understand.. In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley.. So when we start the electric motor the motor rotates at a certain rpm (150-15000 RPM, it may change according to the types of …
• classify the tooling and machine tools, and • recognise various types of operations performed on different machines. 1.2 BASICS OF TOOL ENGINEERING Machine tools are very important for any industrialised country because they hold a key position in the technology chain. Machine tools are needed to build the machines and
• Selective grinding – Grinding operation is carried out in various stages depending upon the differences in structural and mechanical properties of components of grain . Degree of grinding • Ratio of the overall surface area of the ground product to the overall surface area of the feed Dg = Sp/Sf . Dg – degree of grinding
flow, either by manual grinding using shaped grinding tools, or by electro-grinding. (b) The internal surface of the cylinders of a car engine are turned on a lathe. The surface is then made smooth by grinding, followed by honing and lapping to get an extremely good, mirror-like finish. (c) Sand-paper is used to smooth a rough cut piece of wood. 2.
