Recommended domestic brands and manufacturers of roughness meters
Development status of domestic roughness meter brands
In recent years, with the rapid development of China's precision manufacturing industry, the localization process of roughness meters, as the core equipment for surface quality testing, has accelerated significantly. The past reliance on imported equipment is changing. Domestic brands continue to make breakthroughs in accuracy, stability and cost performance, and have been widely used in automobile manufacturing, aerospace, precision machining and other fields. As a leading domestic testing instrument service provider, Shanghai Dexun Zhike Technology Development Co., Ltd. has long been paying attention to the technological evolution and market structure of domestic roughness meters, and is committed to recommending high-quality domestic brands and manufacturers to enterprises.
Recommendation and comparison of mainstream domestic brands
At present, the domestic roughness meter brands with outstanding performance on the market mainly include Shanghai Instrument Electronics, Changchun Kexin, Shenzhen Sansi Zongheng, etc. These brands have gradually achieved independent control over their core technologies, and some of their products have reached the testing level of similar international equipment.
| brand | Representative series | Measuring range | Accuracy level | Applicable scenarios |
|---|---|---|---|---|
| Shanghai Instrument & Electronics | Surface roughness meter series | Ra 0.025~6.3μm | ±8% | General machining |
| Changchun Kexin | Roughness meter KX series | Ra 0.01~10μm | ±6% | Precision manufacturing |
| Shenzhen Sansi Zongheng | Roughness meter TS series | Ra 0.025~8μm | ±7% | Auto parts testing |
How to choose the right roughness meter manufacturer
When companies purchase roughness meters, they should comprehensively consider the following key factors. The first is whether the measurement accuracy meets the process requirements. The control standards for surface roughness in different processing procedures vary greatly. The second is the stability and repeatability of the instrument. The consistency of long-term data directly affects quality judgment. The third is the perfection of after-sales service, including calibration services, maintenance response and technical support capabilities. Shanghai Dexun Intelligence recommends giving priority to manufacturers with metrological qualification certification and independent research and development capabilities to ensure equipment quality and follow-up services.
Kuxun Intelligence Tips:Roughness meters are precision measuring instruments. When purchasing, be sure to confirm whether the manufacturer has the corresponding production qualifications and measurement verification capabilities to avoid purchasing unguaranteed low-price products.
The future trend of domestic roughness meters
From the perspective of technological development direction, domestic roughness meters are evolving towards intelligence and digitization. The new generation of equipment generally supports data export, cloud storage and docking with MES systems to meet the needs of smart manufacturing in the Industry 4.0 era. At the same time, the market demand for portable and handheld roughness meters continues to grow, providing greater convenience for on-site testing. As the domestic supply chain continues to improve, it is expected that domestic brands will occupy a larger share of the high-end roughness meter market in the next 3 to 5 years and provide better testing solutions for the domestic manufacturing industry.
FAQ
What are the main differences between domestic roughness meters and imported brands?
The gap between domestic roughness meters and imported brands in core accuracy has narrowed, but there is still room for improvement in long-term stability under extreme working conditions. The main advantages are more affordable prices, faster after-sales service response, and stronger local customization capabilities.
What are the most critical parameters when purchasing a roughness meter?
The most critical parameters are measurement accuracy and repeatability. Ra (arithmetic mean deviation) is the most commonly used roughness evaluation index. When purchasing, you need to confirm whether the accuracy level of the instrument meets the company's process standards, and pay attention to the repeated measurement consistency of the instrument.
What level of accuracy can the domestic roughness meter achieve?
The roughness meters of mainstream domestic brands have an accuracy of ±6% to ±8% and a measurement range covering Ra 0.01~10μm, which can meet the testing needs of most industries such as machining, auto parts, and mold manufacturing.
How long is the calibration cycle of the roughness meter?
According to the national standard JJG 109-2019 "Calibration Regulations for Surface Roughness Inspection Instruments", it is recommended that the roughness meter be calibrated once a year. Companies with high-frequency use or key testing positions can appropriately shorten the calibration cycle to half a year.
What are the service advantages of Dexun Intelligence in the field of roughness meters?
Shanghai DeXun Zhike provides one-stop services for selection consultation, equipment procurement, measurement calibration and after-sales maintenance of domestic mainstream roughness meter brands. It has established long-term cooperation with a number of domestic brands to ensure that customers receive the most cost-effective solutions.
What is the approximate price range of domestic roughness meters?
The price range of domestic roughness meters is generally between RMB 8,000 and RMB 30,000. The specific price varies depending on factors such as brand, measurement range, and functional configuration. The price of portable basic models is relatively low, while the price of high-end models with multi-parameter measurement functions is relatively high.
Case
Roughness testing upgrade project for an auto parts company
A well-known auto parts manufacturer in Shanghai has long relied on imported roughness meters on its production line, resulting in high equipment procurement and maintenance costs. After being recommended by Dexun Intelligence, the company switched to a domestic high-end roughness meter brand. On the premise of meeting the accuracy requirements of ISO 2768, the annual inspection cost was reduced by about 40%, and the after-sales response time was shortened from the original 7 days to 24 hours.
Precision mold processing factory roughness meter selection case
A precision mold processing factory in Suzhou has extremely high requirements for the surface roughness of the mold cavity and needs to detect Ra values as low as 0.025μm. The technical team of Dexun Zhike customized a complete testing solution including Changchun Kexin KX series roughness meter, and provided supporting measurement and calibration services to help the company successfully pass the customer's factory inspection.
