The rotary-swivel unit, specially developed to meet the needs of the HLA series, is fully integrated into the control system and can be operated by means of a touch panel or joystick (optional). Different sizes are available, which are equipped with specific feed-through holes to be able to machine long workpieces. Minimum backlash is guaranteed by the built-in belt drive. The indirect path measurement is realized by a closedloop stepper motor. A wide variety of chucks, a stop device, a tailstock and many other customization options are available as options. The precise, manual swivel unit is adjustable in a swivel range of +/-120° and is locked by a clamping lever. To facilitate adjustment at standard angles, the rotary swivel units have a grid that pre-locks for example at a 45° position.
