Series KDC

The KDC Vertical Turning Lathes are intended for turning the cylindrical, conic, and curved surfaces as well as the complex shaped workpieces. As an option the rail Hades May be pro-vided with a live tool spindle making it possible to perform drilling and milling operations.
The use of the latest Siemens SINUMERIC 840D CNC and digital drive technology ensures maximum performance and the complete compatibility of all drive and control components.
Together with numerous optional equipments, Vertical Machining Centers, KDC series are suited to our Customers' specific needs.
The machine tool body system consists of a bed, two columns and a beam all mechanically connected what forms a frame structure. The machine tool basic members as the columns, cross rail, rail head, base, and table are made as high grade iron castings. This ensures both the machine high geometrical stability and its good vibration damping, better than fabricated structures.

Design features:

- Units compact design adjusted to machining
requirements;
- Possibility of workpiece complex machining
in one setup with one or two vertical heads;
- Vertical head ram for turning or milling,
grinding, drilling, and threading;
- High rigidity and high accuracy of machining;
- Accurate lead screws (ball) with nuts for"X"
and "Y" axes and drives through
planetary gears;
- Measuring scales of Heidenhein make;
- One or two full toolhead and tool magazines;
- Separate drive for table positioning when milling
and drilling;
- ISO 50, CAPTO or other tooling system.

Control:

- is carried out from a main control panel located
on a free-standing pendant;
- workpiece loading and centering enabled by
additional control panels for one or two vertical
heads;
