TOS TRENS SE520SL

CNC universal center lathe is designed on the basis of SE 520 Numeric. Thanks to the new bed, the distance between centers was enlarged to 2000 mm. The fully covered working space allows to increase technological possibilities of long work-piece machining. The machine can turn simple, as well as complex shapes work-pieces. The machine can be customized in various optional executions and it can be equipped with various optional accessories. SE 520 SL works as a universal lathe in a manual mode, being controlled by the hand wheels or in the full CNC control to perform demanding technological operations. This enables new machining possibilities for piece production and increase the productivity of small series production.

MAIN FEATURES
•Ideal machine for a user switching from universal lathe to CNC controlled machine
•Easy and comfortable control through large touch screen
•Long lifetime with focus on keeping high machining accuracy
•Spindle drive through belts – minimization of vibrations during machining
•Automatic gear shifting during the working cycle
•Bearings with lifetime grease filling – low operating costs
•Fully covered working space – high stage of operator’s safety, the prevention of flying chips and coolant leaking, allows increased coolant pressure and cutting speed – increase in machining productivity
•Wide scope of executions and accessories – hydraulic clamping, hydraulic tailstock control, hydraulic and manual controlled self-centering rests in various executions, boring bar holder, live tools, wide scope of face plates.
•Intuitive and user friendly software machine control
