DESCRIPTION / QUALITIES

The SBK quick change system is for use on drilling machines, either manual, radial or NC controlled. The system is designed to enable numerous functions to be carried out whilst utilising a single toolholder.

The unique double ball clamping gives a positive drive and allows the precise location of the SEK adaptor in the chuck. The adaptors, which take drills, reamers, counterbores or tapping equip ment, can be changed quickly without the use of additional tools, and are automatically located in the chuck. They are released by retracting the outer sleeve of the chuck axially, which then allows the adaptor to be removed with ease.

The changing of tools can take place either when the machine spindle is stopped. The steep location taper of the unit allows a rapid tool change and the system is designed that the unit can operate in both the vertical or horizontal plane, and for left or right hand rotation.

SBK holders and SEK adaptors can be supplied with internal coolant feed on request. A custom design of this quick change system is available for fully auto matic tool change units on special machines.

Note:

Not suitable for operations with radial forces. E.g. milling and tension forcer e.g. back spotfacing
