TAB – Servo turrets with vertical axis

TAB is a vertical axis turret with bi-directional positioning, no body lifting during the indexing rotation, really simple design, really high performances and request a minimum maintenance.

They use a fully hydraulic locking system and rotate thanks to a BRUSHLESS SERVO MOTOR controlled by a SERVO DRIVE.

Turrets can carry 4/6 tool holders as per DIN 69881 norms;  on demand, they can be supplied with a different number of faces or special body.

TAB turrets can be mounted with the axis in horizontal, slanting position.

Main Characteristics:

• Very high rotation speed with minimum indexing times
• Bi-directional
• Locking and Unlocking without body lifting
• Double sensor for locking and unlocking status
• High rigidity due to the new design
• Possibility to use turret body with 4 or 6 positions.
• Possibility to lock the turret in intermediate positions (24 divisions)
• Coolant output flow through valve on the body side
• Possibility, upon request, to increase the coolant pressure up to 70 bar
