Dental mobile phone blockage torque testerIt is a key device used to accurately evaluate the torque performance of dental phones in a locked state, and its operation must strictly follow the specifications to ensure testing accuracy and equipment safety. Before use, it is necessary to confirm the equipment status: check the stability of the power connection, confirm that the torque sensor and fixture are not physically damaged, and verify the compatibility between the dental phone interface and the tester. Subsequently, perform zero calibration and, if necessary, use a standard torque wrench to verify the accuracy of the sensor, ensuring the reliability of the initial data reference.

The testing process is divided into three steps: first, fix the head of the phone to a dedicated fixture to ensure that the axis is aligned to avoid eccentric force interference; Secondly, select the measurement mode (such as peak torque or dynamic torque) on the operation interface, set the sampling frequency and testing duration (usually the stalling test time is controlled within 3-5 seconds to prevent motor overheating); Finally, start the device and synchronously trigger the operation of the dental mobile phone (pneumatic models require stepping on the foot switch). The tester will automatically apply resistance to simulate a locked state and record the peak torque in real-time (in N · cm or mN · m). The data needs to be saved and a curve graph should be generated. It is recommended to repeat 3-5 times and take the average to eliminate accidental errors.

After the test is completed, it is necessary to first stop the dental phone and then turn off the power/air source of the tester. Disassemble the phone and check for any abnormal heating or mechanical wear on the head. If the torque value exceeds the nominal range (such as high-speed phones, which are usually...)0～200mN. m）This may indicate internal bearing loss or transmission failure, requiring further maintenance. In terms of equipment maintenance, it is necessary to regularly clean fixtures, maintain dust-proof sensors, and calibrate them according to standard cycles. This device strictly complies with clause 7.16 of YY1045-2021 standard, and provides scientific basis for quality control, fault diagnosis, and performance optimization of dental mobile phones through high-precision torque sensors and digital detection technology. It is widely used in production quality inspection, maintenance centers, and scientific research institutions.
