Centering Clamping Mandrels
EH 23340.
The centering clamping mandrels are often used in mechanical engineering. However, thanks to their simple operation and quick assembly, they can be used in all industries.
Centering clamping mandrels are used for centering and clamping of workpieces with a locating hole.
The centering clamping mandrels have the following characteristics:
- Very high accuracy for turning/milling processes
- Ideal for secondary operations on turned parts
- Hardened and coated screw for long service life
- Clamping body can be machined very easily (for adaptation to bore diameter)

Notes
Special types on request.
Assembly
The centering clamping mandrel can be machined to the required seating diameter (e.g. by turning/milling). It must be noticed that before machining the centering clamping mandrel, it will be expanded approx. 0.1 mm over the clamping diameter. To machine the mandrel, a nut will be provided.
Further or detailed information can be found in the assembly and operating instructions.
