Introduction to Grinding Machines
A grinding machine, generally known as grinder, is a machine tool which is used for grinding purposes. Any material which has to be broken down into finer particles has to undergo a grinding machine. Just as our teeth grind the food to break it into simpler soluble substances, the grinding machine does the same, though mechanically. Grinders use an abrasive wheel as a cutting tool. It involves a process called deformation, where each and every grain of abrasive cuts a little chip from the material to be worked upon. A grinder consists of an electrically driven grinder wheel which spins at a speed required by the user. The speed depends on the diameter of the wheel. It also consists of a bed that guides and holds the material that is being worked upon…
Grinders also use coolant, a substance that is required to cool down the heat generated while grinding. Coolants are also applied to moving vehicles for the same purposes. For example, coolants are used in automobiles to reduce the effect of heat generated while driving the vehicle. Since grinders remove material by abrasion, large amount of heat is generated. So a coolant is necessary to cool down a work piece to avoid overheating.
