The cornerstone of the VL 8 turning machine is a machine base of MINERALIT® polymer concrete that guarantees a vibration resistant process, providing for excellent tool life and outstanding machining quality. With a chuck diameter of 500 mm, the pick-up spindle accepts workpieces with a diameter up to 400 mm.
Automation via a Pick-up spindle
The pick-up spindle of the turning machine collects the workpieces from a lateral conveyor belt and takes them to the machining area. It is here that short travel ensures short chip-to-chip times. The machining process is a highly flexible one, allowing for the use of a large variety of tools. It is also possible to link up two turning machines with a component turnover station,creating a flexible production cell, allowing to machine the first and second sides of a workpiece complete in one cycle (i.e. cnc turning). Furthermore, the integration of a Y-axis in the turret allows for the “off-center” machining of more complex geometries.
Additional features ensure a precise machining process. There is, for example, the spindle, where short distances between the bearings, the use of high-precision separable bearings in a tandem-O-tandem arrangement and support bearings with length compensation at the spindle end provide for a particularly sturdy construction. This is an important basic condition for micrometre-precision cnc turning processes. Helping to further maintain precision is the integration of an inspection process into the cycle sequence. The required probe is installed outside the machining area of the turning machines and checks the workpiece while it is still clamped. Any corrective data is sent to the CNC control and the process adjusted accordingly. This guarantees consistently high precision, even during automatic operation of the turning machines.
