Three coordinate measuring machineWidely used in industries such as machinery, electronics, instrumentation, and plastics. The coordinate measuring machine is one of the effective methods for measuring and obtaining dimensional data, as it can replace various surface measurement tools and expensive combination gauges, and reduce the time required for complex measurement tasks from hours to minutes, which is an effect that other instruments cannot achieve.
Host introduction:
Adopting excellent finite element analysis design methods, it has the advantages of strong mechanical structural rigidity, small geometric errors, high precision, high performance, and high stability.
The overall mechanical structure adopts a fully enclosed frame mobile bridge structure with good rigidity and light weight. Its structure is simple, compact, with high load-bearing capacity and good sports performance.
Fixed high-quality granite workbench with strong load-bearing capacity, wide loading and unloading space, and convenience.
The Y-direction guide rail adopts a dovetail type, with high positioning accuracy and good stability performance.
The three-axis adopts high-quality granite with low thermal expansion coefficient. The three-axis has the same temperature characteristics, thus it has good temperature stability, resistance to effective deformation, good rigidity, and small dynamic geometric error deformation.
The three-axis system adopts a static pressure air floating guide rail composed of self-cleaning preloaded high-precision air bearings. The bearings have a large span, strong anti angular swing ability, low resistance, no wear, and smoother movement.
The crossbeam adopts precision giant design technology, with light weight, low center of gravity, strong rigidity, and small dynamic error, ensuring the stability of the machine.
Adopting the Renishaw metal strip grating measurement system from the UK, it has a thermal expansion coefficient similar to most workpieces, ensuring good repeatability accuracy.
The drive system adopts high-performance DC servo motors and toothed belt transmission devices from international brands, ensuring faster, more accurate transmission and better motion performance.
The Z-axis adopts a cylinder balancing device, which greatly improves the positioning accuracy and stability of the Z-axis.
The control system adopts the Renishaw special three coordinate numerical control system from the UK, which has an excellent dual computer system with upper and lower computers, greatly improving the reliability and anti-interference ability of the system and reducing maintenance costs.
Due to the crucial role of compressed air in the normal operation of a coordinate measuring instrument, maintenance and upkeep of the air source are essential. Among them, there are the following main projects:
1. Before using a coordinate measuring instrument every day, check the pipes and filters, and drain the water and oil from the filters, as well as from the air compressor or storage tank.
2. Generally, it takes 3 months to clean the filter elements of the random filter and the pre filter. The cycle of poor air quality needs to be shortened. Because the filter element of the filter is also contaminated and blocked by oil while filtering oil and water, a longer time will cause the actual working pressure of the measuring machine to decrease, affecting the normal operation of the coordinate measuring instrument. Be sure to regularly clean the filter element.
