Device with at least one movement unit

A device for numerically controlled (NC) manufacturing, manipulating and measuring apparatuses, said device comprising:

• a frame structure (2) having peripherally arranged force-introduction locations;
• at least one movement unit (3) having peripherally arranged force-introduction locations;
• at least three adjusting devices (1) each comprising a first and a second part;
• each one of said three adjusting devices having a first connecting member (4) and a second connecting member (6) positioned at a spacing to said first connecting member (4);
• wherein said first parts are connected by said first connecting members (4) to said force introduction locations of said movement unit (3), wherein said force introduction locations of said movement unit (3) are positioned in a first imaginary coupling plane (5) of said movement unit (3);
• wherein said first parts are connected by said second connecting members (6) to said force introduction locations of said frame structure (2), wherein said force introduction locations of said frame structure (2) are positioned in a first imaginary coupling plane (7) of said frame structure (2);
• wherein said second parts are connected by said first connecting members (4) to said movement unit (3), wherein said first connecting members (4) are positioned in a second imaginary coupling plane (8) of said movement unit (3);
• wherein said second parts are connected by said second connecting members (6) to said frame structure (2), wherein said second connecting members (6) are positioned in a second imaginary coupling plane (9) of said frame structure (2);
• wherein at least one of said second coupling planes (8, 9) has a fixed spacing to said first coupling planes (5, 7) such that said at least three adjusting devices (1), in standstill positions and during path movement of said movement unit (3) by correspondingly calculated and adjusted lengthening or shortening thereof, are at all times under a defined tension load.
