dividing

This specialized workpiece-holding device, often used in conjunction with a milling machine, allows for the precise rotational indexing of a part. This enables the creation of evenly spaced features such as gear teeth, splines, or bolt holes on a cylindrical workpiece. For instance, a circular plate could be mounted on this device to mill slots at precise 30-degree intervals.

The ability to accurately divide a rotation into specific increments is crucial for various machining operations, particularly in toolmaking, prototyping, and small-batch production. Before the widespread adoption of computer numerical control (CNC) machining, this device was essential for creating complex geometries. It remains a valuable tool in workshops where manual machining is still practiced or for specialized tasks where CNC may not be cost-effective. Its enduring relevance stems from its inherent simplicity, precision, and adaptability to diverse workpiece sizes.

A specialized workpiece holder used in conjunction with a milling machine, this device allows for precise rotational positioning of a part. It enables the creation of evenly spaced features like gear teeth, splines, and bolt holes. For instance, creating a hexagonal nut requires six equal rotations of the workpiece, and this device ensures each face is machined accurately.

This tooling offers significant advantages in manufacturing, facilitating the production of complex components with high accuracy and repeatability. Its ability to divide a circle into practically any number of divisions is essential for industries requiring intricate parts. Historically, the need for precise angular divisions predates modern machining, with evidence of similar principles applied in clockmaking and astronomical instrumentation. This legacy continues in contemporary manufacturing, enabling advancements across various sectors.
