TOS TRENS SE820

SE 820 NUMERIC is a machine from category CNC universal center lathe designed for turning large rotational workpieces. It allows for turning outer and inner cylindrical, conical and complex shapes and all kinds of threads as well. In combination with drilling and milling it allows machining of complex shapes from bars, forgings and split material. Wide variability in specific turning operations for gas, oil and water industries.

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
•Headstock with 2 speed gearbox – possibility of big diameter workpiece turning
•Automatic gear shifting during the working cycle
•Bearings with lifetime grease filling – low operating costs
•Direct spindle position measurement-high accuracy in out-of-axis machining at big diameters
•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, C-axis with servomotor, options for enlarged distances between centers, steady rests and faceplates
