Series KCI

The VMCs, KCI series are designed to perform machining operations in a range of turning, boring, drilling, screw cutting, taper turning, and milling.
All machining operations as well as measurements controlled by a computer numerical control system according to a technological program. Together with numerous optional equipments, Vertical Machining Centers, KCI series are suited to our Customers' specific needs. Our many-year experience in machine tool designing and manufacturing places these VMCs among the best in the world.
The machine tool body system consists of a bed, two columns and a beam all mechanically connected what forms a frame structure. The bodies are made as iron castings while the connecting beam is welded.

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, KM 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;

When tool magazine applied, a special control panel for tool exchange is provided;
