INTEGRATED WHEEL BALANCER
A special vibration sensor, which is permanently installed in the lower part of the rotary table, detects the vibrations that occur. The associated balancing electronics then suggest the necessary counterweight to the operator at a certain number of degrees and in the diameter of the table. If necessary, the operator can change the suggested parameters according to the conditions on the balancing electronics and have new calculations made.
Operation is via the 840 D control unit.

MINIMUM QUANTITY LUBRICATION
(single-channel system)
Minimum quantity lubrication with lubricant supply through the tool spindle. Package consisting of: LUBRIX 850 incl. accessories. The MQL system is adapted to the specific machining conditions by the CNC control system via setting parameters. The oil flow and oil supply are monitored with feedback to the machine.
It is recommended to coordinate the machining task with Lubrix and the tool supplier.

Arranged in the rear area of the machine bed. For automatically flushing the chips into the chip conveyor.
RINSING GUN AT THE WORK AREA
Cooling water supply via a flexible hose.
COLLISION MONITORING SYSTEM 1-CHANNEL
Collision monitoring monitors machine and conditional tool collision
Specification of the collision process limit (channel 1):
The process limit for the 1st channel (collision) can be adapted to the machining process by the machine operator via the control unit on the monitoring system. If lower forces occur during machining, the process limit can be reduced, causing the machine to switch off earlier in the event of a collision, thus minimizing damage.
If the force signal exceeds the process limit, the machine is switched off and all axes are braked with maximum torque.
