Jan 13,2025 Author：lihejingmi Source：lihejingmi Visits：1346
Testing equipment plays an increasingly important role in ensuring product quality, improving production efficiency, and reducing costs. Among high-precision testing equipment, coordinate measuring machines are the most common. So, how can enterprises choose the most suitable coordinate measuring machine? Below are some key purchasing points.
1. Clarify measurement requirements
Travel range requirement: Select the appropriate coordinate measuring machine travel based on the maximum size of the measured workpiece.
Accuracy requirement: Determine the required measurement accuracy according to the tolerance requirements of the workpiece drawing and with reference to the "3x Rule".
Load-bearing requirement: Generally, the load-bearing capacity of the machine only needs to be greater than that required by the measured workpiece to meet your measurement needs.
Measurement type requirement: Touch-trigger measurement, scanning measurement, and non-contact measurement are common measurement types. Touch-trigger measurement is suitable for single-point measurement; scanning measurement is suitable for quickly acquiring a large number of data points on the object surface; and non-contact measurement has the advantage of not damaging the surface of the measured workpiece. Enterprises should select the appropriate measurement type based on the characteristics of the measured workpiece and measurement requirements, and then choose the matching components accordingly.
2. Evaluate coordinate measuring machine performance
The performance of the equipment is mainly determined by factors such as the main machine material and structure. It is recommended to choose a main machine frame with uniform material and a stable main machine structure to ensure the stable operation of the coordinate measuring machine under different temperatures.
3. Evaluate measurement software
Understand the mainstream software trends in the measurement industry and select appropriate software functions, including the reliability of the software's calculation methods and their determining factors. Check whether the tolerance report generated by the software can meet the requirements. The power of software functions directly affects the measurement efficiency and reliability of the coordinate measuring machine.
4. Choose a reliable coordinate measuring machine brand
It is recommended that enterprises purchase from well-known companies with guaranteed product quality and reliable after-sales service.
