History. The origins of the cylindrical grinder, as with all other modern machine tools, stem from the experimentation and invention of John Wilkinson and later Henry Maudslay who built the first horizontal boring machine and the first engine lathe, respectively.The cylindrical grinder owes much of its development from the onset of the Industrial Revolution, particularly to the advent of

A surface grinder is a machine tool used to provide precision ground surfaces, either to a critical size or for the surface finish.. The typical precision of a surface grinder depends on the type and usage, however 0.002 mm ( 0.0001 in) should be achievable on most surface grinders

The basis for today's modern cylindrical grinder was first built in the 1830s by two men working independently, Jonathan Bridges and James Wheaton. These cylindrical grinders evolved from the first horizontal boring machines and lathes, and were further refined in the late 1870s when Brown & Sharpe began manufacturing parts of the sewing machine

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
