6 Operation
Using the manual block clamp
36
Blocks with 6 mm diameter block holders
NOTICE
Fastening the block
Fasten the block tightly
If the block is not tightened sufficiently, this may result in falsification of the
milling result and fracturing of its ceramic material.
➢ Tighten the block securely with the block clamp tool.
➢ Check to make sure that the block is seated very firmly.
1. Insert the adapter sleeve (A) into the block clamp.
NOTICE
Insert the adapter sleeve
The slot at the bottom end of the adapter sleeve must lie above the radial
pin of the block fastener in order to be inserted fully.
The hole for the ball pressure screw is then automatically in the correct
position, i.e. coincides with the threaded hole in the block clamp.
2. Insert the block (B) into the block adapter sleeve.
3. Clamp the ceramic block securely with the ball pressure screw (C). Use
the block clamp tool for this purpose.
The block is pressed laterally against the contact surface of the block
clamp and simultaneously pulled in axially. The plate of the block
holder thus rests on the block clamp.
Removing the adapter sleeve
1. Loosen the ball pressure screw.
2. Place the block clamp tool in the inner groove (D) and pull out the adapter
sleeve.
