FAQ
What is the main measurement principle of the roundness meter?
The roundness meter mainly collects radius change data in the circumferential direction of the workpiece through a rotating workbench or measuring probe, and analyzes the roundness error through software algorithms.Common methods include turntable, probe and optical measurements.
What is the difference between a roundness meter and a cylindricity meter?
The roundness meter mainly measures the circular deviation of a single cross-section, while the cylindricity meter can simultaneously evaluate the shape error of the entire cylindrical surface, including roundness, straightness, taper and other indicators.
How big is the gap between domestic roundness meters and imported brands?
In the field of high-end precision measurement, imported brands still have advantages in terms of long-term stability and measurement uncertainty; but in conventional industrial inspection scenarios, domestic brands can meet most accuracy requirements and are more cost-effective.
How are the accuracy levels of roundness meters divided?
The accuracy of roundness meters is usually expressed in terms of measurement uncertainty, which is divided into micron level (above 1 μm) and sub-micron level (below 1 μm). High-end equipment can reach 0.1 μm level, which needs to be selected according to the tolerance requirements of the workpiece.
How to choose a roundness meter brand suitable for your enterprise?
It is recommended to make a comprehensive evaluation from the four dimensions of measurement needs, budget range, after-sales service response speed and industry application cases, and give priority to brands with mature application experience in this industry.
What should we pay attention to in daily maintenance of roundness meter?
The measurement environment should be kept at a constant temperature and humidity, standard ring gauges should be calibrated regularly, the probe should not hit hard objects, and the spindle system should be lubricated and maintained on time to ensure measurement accuracy and equipment life.
Case
Roundness meter upgrade project for a bearing manufacturing company
The company originally used a domestic basic roundness meter, but because the product accuracy requirements were raised to P5 bearing standards, it decided to introduce a Japanese Mitutoyo roundness meter.After the upgrade, the first-time pass rate of products increased from 87% to 96%, the annual waste loss was reduced by approximately 1.2 million yuan, and the investment payback period was less than 18 months.
Construction of precision testing center for auto parts suppliers
When a German auto parts supplier built a precision inspection center, it selected a Zeiss roundness meter to be used in conjunction with a three-dimensional coordinate measuring machine to achieve full inspection coverage of key components such as crankshafts and camshafts. The measurement data was directly connected to the MES system to promote the digital upgrade of the quality traceability system.
