Shaper Machine
Shaper is a versatile machine which is primarily intended for producing flat surfaces. These surfaces may be horizontal, vertical or inclined. This machine involves the use of single point cutting tool held in a properly designed tool box mounted on a reciprocating ram.
Lathe Machine
A lathe is a powered mechanical device in which the work is held and rotated against a suitable cutting tool for producing cylindrical forms in the metal, wood or any other suitable machinable material.
Machine Shop
The shop where most of the work is performed on different machines is called machine shop. In Machine shop, the raw material is cut, machined, formed or shaped with the help of machines. Different machines used in machine shop are:
1. Lathe machine
2. Shaper
