Vertical Machine Tools
Total Quality Control by In-house Production
OKK does not follow the trend in outsourcing the part production.
All key components are manufactured in house, this includes:
  • all castings
  • all linear slide guide ways
  • ball screw systems
  • all spindle systems
  • all mechanical gears
  • certain controller features and many more...

This guarantees 100% know-how of the core technologies, the production and the final machine performance. For you as our end user, it simply means excellent machine tools with outstanding precision and reliability over exceptional lifetime periods. Not only for standard usage, but especially for high speed, heavy duty cutting.

OKK Concepts of Spindle Systems
Light duty-High speed: motor/coupling/spindle-concept
Medium duty-High speed: direct driven spindle-concept
Heavy duty-Medium speed:    motor/gear/spindle-concept for highest torques
Full thermal control: minimized spindle nose displacement by additional, 
patented cooling systems for spindles and gears

Radiation cooling system in addition to the conventional oil cooling jacket (not drawn)

OKK Square Slide Guideways for:
Workpiece Precision: No overhang in Y-axis, i.e. saddle does not move over the end of the slide guideway
Optimum surface quality:    Superb vibration damping by large contact areas of slide elements
Long Lifetime: Slide surfaces heat treated, nitride hardened and fine grinded
VM7 with 4 guideways in the Y-axis
High Dynamics: Up to 36 m/min rapid speed
Heavy duty cutting: 7 surface locking possible for accepting forces in any direction (X/Y-axes)

Option: 7 surface locking

Hybrid Guide
Load Relieving System
Recommended option, especially for high table loads - compressed air is applied into the bearing pads of the precision squared sliding guides.

The result is an improved cutting accuracy by:

  • considerable reduction of the surface pressure in the slideway, generated by the mass of table and workpiece
  • minimization of the Lost-Motion values

Over 60 Years Casting Production in Own Foundry
  • Extreme rigidity and stiffness by optimised part shapes (e.g. diagonal ribs)
  • Excellent absorption of shocks loads and vibrations
  • Long time stability of the machine
  • Distortion of machine body virtually impossible
