The chuck is a front-end compression chuck, with a larger opening when expanded in a free state due to the pressure on the material. The concentricity requirement is not too high, generally below 0.01MM. The guide sleeve is used to clamp the material for thread tensioning, with a smaller expanded opening and higher concentricity requirements, generally below 0.005MM. The chuck and guide sleeve are a set used together. Below, our editor will provide a detailed introduction.

The cone chuck features straight slots on its cone section with an internal hole. The cone section is matched with the corresponding cone bore on the machine tool. When the collet is subjected to an axial pull force, it displaces relative to the cone bore on the machine. Due to the cone's action, the collet's inner hole narrows, securely gripping the workpiece or tool inside. The P10 alloy sleeve collet set is designed for the Yamamura King main machine and the 1186S boring machine. Made from imported alloy for wear resistance and stable material clamping, it ensures product processing accuracy. The outer casing is made of spring steel to maintain its elasticity and usage lifespan.

The collet is manufactured using spring steel, ensuring precision with cutting types that can be guaranteed within 0.01-0.015 accuracy. Employing segmented heat treatment further extends the collet's lifespan and boasts excellent wear resistance, utilizing self-张开 technology.

Head and guide sleeve exchange注意事项：

Prior to any material combustion incidents, it's challenging to determine the necessity of replacing collets and guide bushes. However, failure to replace them before they are burnt or damaged may be a cause of machine malfunctions. The following points serve as a reference for judgment:

1. As the product enters the manufacturing process and precision begins to fluctuate.

2. The expansion degree (the difference between the inner diameter when the clamp and sleeve are open and when they are in use) decreases. (It is usually normal to be around 0.3mm.)

3. The conical section of the machine's outer casing has scratches or variations in the flat surface.

4. Internal diameters are subject to wear, making adjustment of clearances challenging. (Requirements for processing product progress and the need for collet chuck guide sleeve exchange also vary.)
