NT Tool offers its high-accuracy hydraulic chucks in a slim PHC-S toolholder for use in tight spaces. The PHC-S holder provides the stability and precision of NT’s dual clamping-point system with access into narrow workpieces previously only possible with shrink-fit holders. The PHC-S is available in HSK, CAT (standard and two-face contact), BT (standard and two-face contact) and UTS shank styles. They are offered in inch sizes ranging from ¼" to 1" in diameter and metric sizes ranging from 6 to 25 mm in diameter. Custom sizes are also available.
The oil chamber around the chucking sleeve absorbs cutting vibrations, which allows for consistently higher accuracy and a smoother work surface compared to shrink-fit holders, says the company. The PHC-S model is said to provide accuracy down to 3 microns. An electromagnetic rustproof coating ensures that this accuracy is maintained throughout the life of the holder.
Setup requires only a one-handed hex wrench to clamp the cutting tool. This design reduces downtime and eliminates the risk of burn injuries associated with shrink-fit chucking for tight-space applications.
