CoroTurn® 300

Effective and high-quality turning

Instructions

Insert change

The insert is changed in five easy steps. A clamping solution with lever makes the insert self-locking in the tip seat, and fixed location points (iLock™) ensure rigidity and accuracy. Use a torque of 4.5 Nm.

Coolant connection on QS™ shanks

There are four ways to connect the coolant: using an adapter (first choice), using the rear tube connection, with front and underneath connection, or with the rear tube connection with a QS stop.

Coolant supply

By plugging the coolant holes, you can choose between using just over or under coolant, or both, which is the standard setup.

Clamp assembly

For correct assembly of the wedge clamp, the double-threaded screw needs to be assembled with one revolution into the wedge clamp.

Clamp assembly

Assemble the screw/wedge clamp into the pocket, position for insert fixture and ensure that the screw is not protruding.

Information on tool holder

On the tool holder, you will find markings that give you information about the product family, article code, batch number, spare parts, torque value, key grip and maximum coolant pressure.
