Repair Sanfeng Rockwell hardness tester

1、 What is a Rockwell hardness tester? Firstly, let's briefly understand the principle of Rockwell hardness testing: it measures the effect of the indenter on the initial test force (preload) and total test force (main load)

The depth difference of pressing down on the surface of the material

Calculate the hardness value. This testing method is fast, direct, and suitable for a wide range of materials from soft metals such as aluminum and copper to hard steels such as quenched steel. 2、 The core features and advantages of the Sanfeng Rockwell hardness tester. The Sanfeng brand has demonstrated several significant advantages in accuracy and repeatability in its Rockwell hardness tester, including high-precision sensors that use a precise displacement measurement system to ensure the accuracy of indentation depth measurement. Stable loading mechanism: Precise mechanical structure or closed-loop controlled electric loading system ensures smooth and accurate application of test force, ensuring the repeatability of test results. Compliant with international standards: Its products strictly follow international standards such as ISO 6508 and ASTM E18 to ensure the recognition of test data. Durable and Reliable: High Quality Materials and Manufacturing: The body is made of high-quality cast iron or steel structure with high rigidity, which can effectively absorb vibration and ensure long-term stability. Long life design: Core components such as pressure heads, test force springs/motors, etc. have been specially designed and treated to be wear-resistant, durable, and have a low failure rate. Humanization and ease of use: intuitive operation: whether it is traditional dial or digital display, the operation process is designed very clearly. The intelligence of digital display models: Digital display models are usually equipped with large LCD screens, which can directly display hardness values, conversion values, statistical data, and test curves. Automation function: Many models have automatic loading, holding, and unloading functions, reducing human operation errors and improving testing efficiency. Complete range of models and wide applications: Sanfeng offers a variety of models from traditional manual, electric to fully automatic to meet the needs of different industries and budgets. Can be equipped with multiple indenters and testing forces, supporting Rockwell hardness (HRC, HRB, HRA, etc.), surface Rockwell hardness (HR15N, HR30N, HR45N, etc.)

And the testing of various hardness scales such as Brinell and Vickers (some models require corresponding accessories). 3、 Main series and model introduction: Sanfeng's Rockwell hardness tester is mainly divided into the following series: ATK series (digital electric type) Features: This is Sanfeng's mainstream electric Rockwell hardness tester series. Driven by a motor, the test force is automatically applied, the operation is simple, and the results are reliable. Advantages: High precision and efficiency, very suitable for routine testing in laboratories, quality inspection departments, and production sites. Representative model: ATK-6000, this is a very classic model with multiple functions, such as hardness value conversion, data output, etc. ARK series (digital manual type) features: The operator needs to manually rotate the handwheel to apply test force. Compared to electric models, the cost is lower, but the core measurement system is still Sanfeng's high-precision standard. Advantages: High cost-effectiveness, suitable for users with limited budgets but still requiring high-precision measurements. Representative model: ARK-6000 Traditional dial type (such as HR-500 series) Features: Hardness values can be directly read through the dial, mechanical structure, very sturdy and durable. Advantages: Simple structure, easy maintenance, low environmental requirements, still widely used in some old factories and specific environments. Fully automatic and special models are designed for high-throughput laboratories or specific industrial needs (such as batch testing of small parts). Sanfeng also provides fully automatic hardness testers that can automatically load, unload, position, and test, greatly improving efficiency. Sanfeng Rockwell hardness testers are widely used in all industries that require material hardness testing: metal heat treatment industry: testing the hardness of workpieces after quenching, tempering, carburizing, and other processes. Aerospace and automotive manufacturing: Strict hardness quality control is applied to key components such as engine crankshafts, gears, and bearings. Steel and alloy manufacturing industry: hardness grading and inspection of raw materials and finished products. Research institutes and quality inspection institutions: conduct material research, performance analysis, and third-party certification testing. Mechanical processing and mold industry: testing the hardness and wear resistance of cutting tools and molds. 5、 When choosing a Sanfeng Rockwell hardness tester, the following points can be considered: Testing requirements: What ruler (HRC/HRB) is mainly tested? Do you need surface Rockwell? ）. Sample type: Test the size, shape, and weight of the sample. Testing frequency: The number of samples to be tested per day determines whether to choose manual, electric, or fully automatic. Budget: The digital electric model is powerful but expensive, while the manual and dial models are more economical. Data management: Do you need the functions of data output, statistical analysis, and connecting to computers/printers.
