4.5 ES370: performing tool change
The ES370 electrospindle is not equipped with a cylinder/piston to perform the tool change. It is
the responsibility of the client in this case to provide an external structure which enables tool
change operations by taking advantage of the exposed area of the screw dowel. The expulsion
system must also provide for a central hole for toolholder cone cleaning in the releasing phase.
