If you are not familiar with what a collet fixture is, please read the following:

Collet fixtures are tools used in machining operations to hold and secure workpieces. As an example,the 5C collet system is a popular standard for holding round workpieces in a lathe, milling machine, or other machining equipment.

A 5C collet fixture typically consists of a base or body that mounts onto the machine’s spindle or worktable, and a mechanism for clamping and releasing the collet. The collet itself is a cylindrical sleeve with internal threads that match the external threads on the workpiece.

Here are a few common types of 5C collet fixtures:

  1. Manual Collet Chuck: A collet chuck is a type of fixture that mounts directly onto the spindle of a lathe or milling machine. It typically has a mechanism, such as a cam or lever, for opening and closing the collet to secure the workpiece. Collet chucks allow for quick and easy collet changes and are commonly used in high-precision machining applications.
  2. Collet block: A collet block is a square or hexagonal block corresponding to a specific collet size. The collets can be inserted into the block, and the block is then mounted onto the machine’s spindle or worktable. Collet blocks are useful for holding multiple workpieces simultaneously or for indexing workpieces at precise angles
  3. Collet indexer: A collet indexer is a rotary device that allows for precise indexing or positioning of workpieces. It typically consists of a base, a spindle, and a mechanism for rotating the spindle in predetermined increments. Collet indexers are commonly used in applications that require machining operations at specific angles, such as milling keyways or drilling holes on a circular flange.

These are just a few examples of 5C collet fixtures. The specific type of fixture used will depend on the machining operation and the requirements of the workpiece being machined. For more information please visit the following page on our website: Collet Fixtures air and manual
