Development status of domestic roundness meter brands

In recent years, with the rapid development of the precision manufacturing industry, domestic roundness meter brands have made significant breakthroughs in technology accumulation and market expansion. As an enterprise deeply involved in the field of domestic precision measurement, Shanghai Dexun Zhike Technology Development Co., Ltd. has observed that domestic roundness meters have gradually shifted from early reliance on imports to independent control. The products have shown strong competitiveness in terms of measurement accuracy, stability and cost-effectiveness.

Domestic roundness meters are mainly used in industries such as bearing manufacturing, auto parts, aerospace and precision molds, and can meet the roundness measurement needs of ITD 0.1μm to 1μm level. Compared with imported brands, domestic equipment is more attractive in terms of after-sales service response speed, customized development and price advantages, and has become the preferred solution for many manufacturing companies.

Comparison of mainstream domestic roundness meter brands

Currently, the mainstream domestic roundness meter brands on the market include Shanghai Measuring Point, Hangzhou Wanhao, Dongguan Zhongguan, etc. Each brand has its own focus on technical routes and product positioning. The following table briefly compares some representative brands:

How to choose a suitable domestic roundness meter

When purchasing a roundness meter, enterprises should comprehensively consider factors such as measurement accuracy requirements, workpiece size range, frequency of use, and budget. First of all, it is necessary to clarify the roundness tolerance level of the parts being measured. Generally, it is recommended to choose ITD 0.1μm level equipment for IT5 level and above accuracy. Secondly, it should be confirmed whether the maximum measurement range of the equipment covers existing and possible future workpiece specifications.

In addition, software functionality and after-sales service are equally critical. A high-quality roundness meter should be equipped with complete analysis software, support ISO, GB and other standards, and be able to output professional test reports. It is recommended to give priority to manufacturers that have independent research and development capabilities, provide on-site training and long-term technical support to ensure long-term stable operation of the equipment.

FAQ

What level of accuracy can the domestic roundness meter achieve?

The measurement accuracy of mainstream domestic roundness meters can reach ITD 0.1μm, which can meet the roundness detection requirements of ISO IT5 and above precision parts. Some high-end models can even cover scientific research-level measurement scenarios.

What are the advantages of domestic roundness meters compared with imported brands?

Domestic roundness meters usually have a 30% to 50% cost advantage in price. At the same time, after-sales service response is faster, customized development is supported, and the software interface is more in line with the usage habits of domestic users.

How should the daily calibration of the roundness meter be performed?

It is recommended to use a standard ring for zero-point calibration before each start-up, and send it to a measurement institution for full parameter verification regularly (such as every quarter) to ensure the traceability and reliability of measurement data.

What types of workpieces can the roundness meter measure?

The roundness meter is suitable for all types of rotating parts, including bearing inner and outer rings, hydraulic valve cores, gauges, gear blanks, precision shafts and mold inserts and other workpieces with rotational symmetry characteristics.

Is software function important when purchasing a roundness meter?

Very important. Excellent measurement software should support multiple roundness evaluation methods (least square circle, minimum area circle, etc.), have data export and SPC statistical analysis functions, and be able to generate inspection reports that meet customer format requirements.

How long is the warranty period for domestic roundness meters?

The standard warranty period of mainstream domestic brands is one year, and some manufacturers provide extended warranty services. When purchasing, you should confirm whether the warranty covers core components (such as sensors, spindles) and on-site maintenance services.

Case

Roundness inspection upgrade project for a precision bearing company

The original imported roundness meter equipment of a bearing manufacturer in Jiangsu is aging, has a high failure rate, and has a maintenance cycle of as long as three months. After switching to Shanghai Dexun Zhike's domestic roundness meter, the measurement efficiency increased by 40%, the annual maintenance cost was reduced by 60%, and the roundness detection pass rate increased from 92% to 98.5%, significantly improving product consistency.

Auto parts supplier batch inspection plan implemented

In response to the batch testing requirements of hydraulic valve cores, an auto parts company in Zhejiang deployed three domestic roundness meters and connected them to the MES system to realize automatic uploading of testing data and real-time SPC monitoring. After the project went online, the inspection time for a single piece was shortened from 8 minutes to 3 minutes, saving about 150,000 yuan in annual labor costs.
