Super-precision hydraulic expanding mandrels are a very precise and suitable alternative for grippers and fixtures available on the market and/or designed for specific purposes. One of the problems in material removal, in highly precise parts, is the need for high alignment, which can easily be achieved using this kind of mandrels. Achievement of precise geometric parameters in the mass production of thin-walled bushes in the automotive industry is among the reasons why they use this kind of mandrels.
In addition to being designed based on customer needs, from among the main advantages of this equipment, we can refer to its low price and being leak free.
The long lifespan of mandrels and their being maintenance free have caused them to have a wide range of applications in the industries of manufacturing brass parts, turning machines, multi-station transfers, and cylinder grinding machines.
Here you can find different hydraulic mandrels from straight (cylindrical) to flange types with or without collar and axial or radial actuation.
