Dividing Head With Gears

Dividing Head With Gears are mechanical devices designed to rotate a workpiece at precise intervals or divisions. These divisions are crucial for executing intricate operations, such as milling, drilling, cutting, or grinding, where specific angular measurements or patterns are required. The gears integrated into the dividing head mechanism allow for precise control of the rotational movement, ensuring accurate positioning and division of the workpiece. The underlying principle behind heads with gears is that they enable the workpiece to be divided into equal segments by indexing or rotating it at specific angles. This division facilitates the creation of complex shapes, precise threads, or any pattern that requires repetitive and accurate positioning.

By coupling the dividing head with an appropriate set of gears, machinists can achieve a wide range of divisions with exceptional precision. The applications of dividing heads with gears span various industries, including manufacturing, automotive, aerospace, and even the creation of intricate jewellery. These tools are particularly valuable in tasks where precision and replication are paramount, such as gear cutting, milling keyways, fluting, and creating splines.
