CLAMPING HEADS OF THE SERIES SPH
Principally used in machining centres for horizontal pallet clamping
Clamping heads of the series SPH are principally used in machining centres for horizontal pallet clamping. With these clamping heads and the attendant tapered rings it is possible to achieve maximum repeating accuracy of the clamping position. In addition to machining centre turntables the clamping heads are also used on individual set-up places.
The shape and positioning accuracy of the clamping cones guarantee maximum pallet change repeating accuracy. The cone surfaces have a surface hardness greater than 60 HRC and special depth of hardness which is resistant to any kind of contamination. The clamping bolt screwed into the pallet with the tapered ring is pulled via clamping segments onto the clamping head by a hydraulic cylinder acting on both sides. An air jet with optimized air guidance is provided to keep the clamping cones clean during pallet changing. These channels can also be used as coolant lubricant channels for rinsing out the clamping heads. Clamping heads are designed economically with a larger tolerance and without lift-out stroke or as support heads only. Modified models, for example without stopper or with air operated position control on request.
