CMM generally fixed gantry structure, high precision and stability of the cold!
The following figure shows the German Zeiss coordinate measuring mechanism made:
All parts are by mechanical precision, high dynamic performance and high resistance to environmental change to design
u bridge measuring machine, fixed table, a single-drive, the shafts are surrounded on all sides using air bearings.
u for each axis computer-aided error correction (CAA precision computer aided)
u spindle and beams, the main column using insensitive to temperature and humidity aerospace ceramic material
u with efficient passive vibration isolation system made of a rubber spring element, without investment cost foundation
u the model with Zeiss RDS automatic rotating probe.
u ergonomic dual-joystick control system.
u ergonomic machine guards outside
u oil filter can be an air filter and drainage means
u are each DC servo motor drive shaft
u advanced geometrical error compensation parameters 21
u rigorous calibration accuracy specification: acceptance stylus length of 40 mm, closer to the user environment. While other brands acceptance probe length was 20mm., Is not really practical for the user environment.
1. Zeiss X-Z coordinate axis key parts using industrial ceramic technology, high precision and long-term stability.
2. coordinate accuracy from grating, microcrystalline glass ceramic Zeiss scale, 0 ° expansion coefficient, the precision from the environment.
