Getting to grips with hydraulic chucks

Thanks to their excellent precision and efficiency, hydraulic chucks have established themselves as real workhorses in the world of machining.

However, to meet the wide-ranging requirements of different industries many variants are needed. This is why Ceratizit is adding two high-performance adapters to its range of hydraulic chucks: the HyPower Rough for demanding rough machining operations and the HyPower Access 4.5° for optimum accessibility in the machining zone.

Ceratizit offers its hydraulic chucks, with VDI interface, as a total solution for the hydraulic clamping of cylindrical tool shanks, boring bars, cylindrical tool holders and fixed base holders in the turrets of turning machines.

Featuring through coolant supply, the hydraulic chucks come with a diameter of 20mm for the VDI 30 and 40 interfaces as standard. Additionally, a cylindrical shank version is also available for turning/milling centres also with through coolant. The chucks come in 16 and 20mm diameters for a 32mm cylinder diameter as well as in variations of 16, 20 and 25mm for a 40mm cylinder diameter. “This provides high-precision clamping with a repeatability of 3µm and very low tolerance ranges,” explains Christoph Retter, product manager clamping systems at Ceratizit.

The HyPower Rough hydraulic chuck has been specially designed for clamping milling tools with a HA shank. With a high temperature stability of 80°C, even during long milling cycles lasting longer than 240 minutes, the HyPower Rough is ideal for highly dynamic milling applications such as HSC (high-speed cutting), HPC (high performance cutting) and SPM (structural part machining).

The chuck is equally as effective during high-performance milling operations of high-quality components up to a maximum of 33,000rpm, offering outstanding process security and an impressive chip removal rate. When used in roughing cycles – an area in which the HyPower Rough truly excels as its name suggests – its highly efficient vibration damping characteristics ensures good surface finishes. 

Where high precision is needed, the HyPower Access 4.5° hydraulic chuck is the perfect choice for precision finishing. To pack in as much flexibility and versatility as possible, its dimensions are exactly matched to those of a shrink-fit chuck (DIN contour with 4.5°).

It also offers customers the advantages of a hydraulic chuck for critical component structures. HyPower Access 4.5° is suitable for reaming and drilling, as well as for finishing during milling operations. Its robust industrial design guarantees maximum process security and tool life.

Ceratizit’s HyPower tools are durable and will withstand years of use, thanks to the HyPower’s vibration damping which reduces spindle load and prolongs tool life. Both the HyPower Access 4.5° and the HyPower Rough offer optimum radial run-out accuracy and an impressive clamping force. They are simple to use: tool changes can be made in minutes using a single Allen key.
