Bit Torque Testing Machine is a testing device specifically used to test the torque performance of various bits (screwdriver bits, driver bits). Bits are wear-prone accessories for power tools, manual screwdrivers, and other tools. Their torsional strength and fatigue life directly affect the effectiveness and safety of the tools.
| Feature | Description |
|---|---|
| High Precision | Typically equipped with Class 0.5 or Class 1 precision torque sensor |
| Small Range | Bits have relatively small torque; common range is 0–50 N·m |
| Dedicated Fixtures | Equipped with various dedicated clamping fixtures for different bit types |
| Computer Control | Fully automated operation with real-time data acquisition and display |
| Bidirectional Loading | Supports both clockwise and counterclockwise torque testing |
| Data Management | Supports data storage, curve display, and report printing |
