Gear shaping machines are machine tools used for the production of gears. Gears are important components in many drive systems and transfer motion and power from one drive to another. Gear shaping machines are used to produce gears from steel or other materials. These machines work by pressing a matrix onto the material to form the teeth. The matrix can be made of different materials such as steel, brass or bronze. Gear shaping machines must be very precise and accurate to ensure high quality gears. Inaccurate or uneven tooth form can lead to malfunction or inadequate transmission of power or motion. As a rule, gear shapers are part of a production line for drive technology or mechanical engineering and work closely with other machine tools such as grinding machines or gear cutting machines to ensure high quality of the manufactured parts.
