Machine tool for triaxial machining of work pieces

A machine tool with a machine rack, the machine tool being used for triaxial machining of workpieces, the machine tool comprising:

• a first rack-proof guide;
• a second rack-proof guide, said first rack-proof guide being arranged substantially in parallel to said second rack-proof guide;
• a first independent drive;
• a second independent drive;
• a first skid disposed on said first rack-proof guide, said first skid being adjustably positionable by said first independent drive;
• a second skid disposed on said second rack-proof guide, said second skid being adjustably positionable by said second independent drive;
• a first hinge;
• a second hinge;
• a first coupler connected by said first hinge to said first skid and being adjustable in said first rack-proof guide in an X-Y plane, said first coupler lying between said first rack-proof guide and said second rack-proof guide, if viewed in a projection on the X-Y plane;
• a second coupler connected by said second hinge to said second skid and being adjustable in said second rack-proof guide in the X-Y plane, said second coupler lying between said first rack-proof guide and said second rack-proof guide, if viewed in a projection on the X-Y plane;
• a common hinge providing the only connection between said first coupler and said second coupler;
• a tool carrier fastened only to said second coupler in the vicinity of said common hinge on a side of said second coupler averted from said first coupler, said tool carrier being unmovable with respect to said second coupler in the X-Y plane and said tool carrier being moveable in the X-Y plane upon movement of said first coupler and said second coupler.
