Specifications of Changchun Electric Torque Wrenches: A Diverse Range

The specifications of Changchun electric torque wrenches vary significantly depending on the manufacturer, the intended application, and the target market. However, several common parameters define their capabilities and performance:

1. Torque Range: This is perhaps the most critical specification. Changchun-manufactured wrenches cater to a wide spectrum of torque requirements, ranging from a few Newton-meters (Nm) for delicate electronic assemblies to several thousand Nm for heavy-duty industrial applications. The torque range is often expressed as a minimum and maximum torque value, indicating the wrench's operational capacity. For example, a typical specification might read "20 Nm - 200 Nm" or "1000 Nm - 5000 Nm".

2. Accuracy: The accuracy of the torque wrench is paramount, ensuring consistent and reliable tightening. This is usually expressed as a percentage of the set torque value. Higher accuracy is generally desired for critical applications where precise torque control is essential. Common accuracy levels range from ±3% to ±1%, with higher accuracy often commanding a premium price.

3. Drive Square Size: This refers to the size of the square drive that accepts sockets and other accessories. Common sizes include 1/4", 3/8", 1/2", 3/4", and 1". The choice of drive size depends on the size and type of fasteners being used.

4. Power Source: Most Changchun electric torque wrenches operate on rechargeable batteries, offering cordless convenience and portability. The battery type, voltage, and run time are crucial considerations. Some models might offer interchangeable batteries for extended operation. The battery life and charging time are key factors in choosing a suitable wrench.

5. Speed Control: Many advanced models incorporate variable speed control, allowing the user to adjust the tightening speed based on the specific application. This feature enhances control and precision, especially when dealing with delicate components.

6. Display and Features: Modern electric torque wrenches often feature digital displays showing the applied torque, set torque value, battery level, and other relevant information. Some models may include additional features like audible alerts, pre-set torque values, and data logging capabilities. These features enhance usability and provide valuable data for quality control and traceability.

7. Weight and Ergonomics: The weight and ergonomic design of the wrench are important factors for user comfort and ease of use, especially during prolonged operation. Lightweight and well-balanced designs reduce operator fatigue.
