SE820 Numeric T.M.C is a machine from category CNC universal center lathe designed for turning large rotational workpieces. It allows turning outer and inner cylindrical, conical and complex shapes and all kinds of threads as well.
In combination with drilling and milling, they allow the machining of complex shapes from bars, forgings, and split material. Wide variability in specific turning operations for gas, oil, and water industries.
Main characteristic features:
- Ideal machine for a user switching from universal center lathe to CNC controlled machine
- C-axis with independent servomotor for achieving precise and stabile work piece position during cutting forces loading
- Easy and comfortable control
- Long lifetime with focus on keeping high machining accuracy
- Headstock with 2-speed gearbox -the 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 the lifetime of the machine
- Covers with reinforced zones – high level of operator´s safety
- Wide selection of optional executions and accessories – hydraulic clamping, hydraulic tailstock control, executions with increased distances between centers, a wide range of steadies and faceplates
These machines combine advantages of conventional and CNC lathes. The machine works as a conventional lathe, in manual mode, being controlled by the hand wheels. If required, the operation mode can be shifted to the full CNC control. Technological operations of machining can be programmed by simple filling-in the pre-defined cycles or eventually by standard programming.
Machines are therefore suitable for piece and small-series production of simple as well as complex shapes of the workpieces from metal and plastic. Geometric accuracy of the machines fulfills norms ISO 1708 and ISO 230-1.
