Quick Change Drilling Chucks and Adaptors for drilling, reaming, and tapping tools
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 equipment, 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 or when runing up to a maximum speed of 2,000 rpm.
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
automatic tool change units on special machines.
Not suitable for operations with radial forces. For example milling.
