Share it:

CNC lathes in several models with
Turning diameter from 320 mm to 1020 mm,
Turning lengths from 720 mm to 8000 mm

Most important features:

Ideal machine for a user switching from conventional to CNC controlled machine
Minimal built-up area
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

CHARACTERISTIC FEATURES:

Apron guideways with layer of friction substance – reaching positional accuracy even at minimal feed
Preloaded ground ball screws – high dimensional accuracy of workpieces
Machine geometry measuring by laser device – exact setting of machine axis parameters
Variability of selection of optional turrets
Constant cutting speed – high quality of turned surfaces
Variety of control systems

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.
