The primary function of the reducing sleeve is to connect tool holders of different diameters with the spindle, ensuring a stable tool system rotation and meeting high precision requirements. Our reducing sleeve is an auxiliary positioning and fixing tools.
Our reducing sleeve, as a specialized tool connection component, can effectively improve machining precision and efficiency, ensuring product quality and production benefits. It’s widely used in the field of CNC machining, it connects and replaces tools of different diameters to the spindle, suitable for various types of lathes, milling machines, and other CNC machine tools.

1. The raw materials are fed into a CNC lathe for preliminary processing to form the basic shape of the tool holder.
2. After preliminary shaping, the tool holder undergoes heat treatment and grinding processes to enhance its durability and precision.
3. Once the tool holder is manufactured, it is assembled and tested to ensure its performance and reliability in practical applications.
Our reducing sleeve is mainly used for mounting and clamping the milling cutter for CNC machine.
We can select different reducing sleeve based on the tail of the live center when mounting.
