TOS TRENS SE520

SE 520 NUMERIC is a machine designed for small to medium series production of smaller dimensions workpieces. This machine is also suitable for shops with piece production. This lathe can turn simple as well as complex shape workpieces such as flanges and shafts from metal and plastic. SE 520 is also suitable as a teaching aid for vocational schools and colleges of technical major. Machine can be operated either in manual mode, by using electronic handwheels, or the technological operations can be performed in automatic mode, thanks to the modern control system. Using the automatic mode opens new possibilities in piece production and in increasing the productivity of small series production.

Most important features:
•Ideal machine for a user switching from conventional to CNC controlled machine
•Easy and comfortable control
•Long lifetime with focus on keeping high machining accuracy
•Spindle drive through belts – minimization of vibration level that could negatively influence turning
•Automatic gear shifting during the working cycle
•Bearings with lifetime grease filling – low operating costs
•Annealed machine components for internal stress removal – high accuracy and stability throughout lifetime of the machine
•Machine covers with reinforced areas – high level of operator protection
•Wide selection of optional executions and accessories – hydraulic clamping, hydraulic tailstock control, turret with live tools, steady rests and faceplates
