ER COOLANT SEALING COLLET uses the difference of the groove to achieve the function of surrounding waterstop, only the central water outlet, and is suitable for clamping the tool of the water outlet hole. The ordinary ER collet groove is a through groove, which does not play the role of waterstop

CNC ER sealed collet spring collet is a type of collet used in CNC machining. It is designed to securely hold a tool or workpiece in place during machining operations. The "ER" in the name refers to the standard ER collet system, which is widely used in the industry.

The "sealed" aspect of the collet means that it is designed to prevent the entry of coolant or other fluids into the collet, which can cause corrosion or damage to the collet and affect its performance. This is particularly important in CNC machining where coolant is often used to cool and lubriCATEEe the cutting tool.

The spring collet refers to the mechanism inside the collet that provides the gripping force. The collet has multiple slits along its length, and when a tool or workpiece is inserted, the collet compresses slightly, gripping the tool or workpiece tightly. The spring collet allows for a quick and easy tool change, as the collet can be opened and closed by simply tightening or loosening a nut.

Overall, the CNC ER sealed collet spring collet is a reliable and efficient tool holding solution for CNC machining, providing a secure grip on the tool or workpiece while preventing fluid contamination.
