Introduction • A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. In this type of grinding operation two grinding wheels are fitted parallel with a little 5-10 degree angle, this angle is provided to get a longitudinal motion of the workpiece. The rough surface of the abrasive wheel shreds off small portions of the work piece as required. It is also widely used for producing the tools needed in the woodworking and metal cutting industries. As the name indicates Portable that means it is not fixed at one point. This allows the workpiece to automatically pass through the wheels and the smooth surface is obtained. In wet grinding, during the grinding operation, we sprayed coolant generally water or any coolant to cool the surface so that the longevity of the grinding wheel increases and also we get a fine surface finish. A cylindrical rod is entered between the two grinding wheel due to the tilted angle the workpiece is automatically pass through the wheels, and we got a smooth surface. The portable grinder is used for cutting tiles. Almost it is capable of doing any milling operation whether it is gear milling, thread milling, angular milling etc. The job passes through the wheel, automatically the pre-determined shape is formed on the workpiece. Required fields are marked *. I hope you understand all these and also I share some videos by NPTEL I highly recommend you to go through all these videos and clear your doubts. It is also known as a grinder. In the wet grinding coolant like water or any other cooling substance will be sprayed to cool the surface so that the longevity of the grinding wheel increases and obtained a fine surface finish. 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 grinding machine) with the help of v-belt and cone pulley the grinding wheel also starts rotating and we perform the operation. This is fitted on a pedestal frame separately on the ground. I hope you enjoyed reading the reading if so kindly comment, share and check some interesting topic below.
