Center Lathe Machine

One of the oldest machine tools is a lathe machine. In 1797, an Englishman, Henry Maudslay, designed the first screw-cutting lathe which is the forerunner of the present-day high speed, heavy-duty production lathe.

The lathe helps remove metal from a piece of work to give it the required shape and size. This is accomplished by holding the work securely and rigidly on the machine and then turning it against a cutting tool that removes metal from the work in the form of chips and shavings.

Tool Grinding Machine

A grinding machine, often shortened to grinder, is one of the power tools or machine tools used for grinding purposes.

Tool grinding machines are used to produce and re-sharpen tools.
