Sliding/fixed headstock automatic lathe TNL20 The workpiece discharge unit – fast, safe and gentle Flushing unit for workpieces Small workpieces weighing up to approx. 150 g and up to 20 mm in diameter can be flushed out easily, quickly and gently from the counter spindle through the indexing shaft of the lower tool turret by means of an optional flushing unit. A ring sensor monitors and confirms the safe discharge of the workpieces to the right into a workpiece container or onto an optional part conveyor belt. Workpiece removal unit The workpiece removal unit (servo linear axis in...

Integrated robot cell Intelligent automation – even more flexibility and efficiency With the optional robotic cell, blanks and/or finished parts can be supplied and discharged quickly, safely and flexibly. The robot cell is integrated ergonomically into the machine. It can be moved easily to the left during the setup process, allowing unobstructed access to the work area of the machine. During production, the robot cell is fixed in front of the machine’s work area. The robot then accesses the work area via the sliding guard of the machine, which opens automatically behind the robot cell....
