Coordinate measuring apparatus having a bending-resistant measuring table

A coordinate measuring apparatus comprising:

• a bending-resistant measuring table defining a longitudinal axis and configured as a ribbed hollow body;
• said measuring table having a table top of completely closed unitary construction and having first and second longitudinal ends;
• said ribbed hollow body and said table top conjointly being a single cast body;
• said table top having a central measuring region extending between said first and second longitudinal ends whereat measurements of a workpiece are made and said table top having a guide region extending in the direction of said longitudinal axis next to said central measuring region;
• said measuring table being configured with said guide region extending a predetermined distance beyond each of said first and second longitudinal ends;
• a measuring assembly for making measurements on a workpiece placed on said central measuring region;
• and,
• said measuring assembly being movably guided along the entire length of said guide region including beyond said longitudinal ends so as to permit measurements to be made on the workpiece irrespective of where on said central measuring region the workpiece is placed wherein said guide region includes an upper surface and said table top defines a single plane containing said central measuring region and said upper surface of said guide region.
