This automatic precision surface grinding machine is a customized special equipment developed by Shenyang Longteng Electronics Co., Ltd. It is designed for the precision planar machining of magnetic steel and magnetic conductive sheets of electromagnetic weighing sensors.
The machine adopts fully enclosed dust-proof body to avoid dust interference during precision grinding. Workpieces are fixed by vacuum adsorption tooling. Users can set grinding parameters via the cantilever HMI touch screen, including rotation speed, grinding pressure and working time. The transparent observation windows allow operators to check the machining process without opening the cabinet.
It can guarantee excellent flatness and consistency for mass production of sensor magnetic components, which is critical to ensure the accuracy and repeatability of high-end electronic balances and weighing instruments. The equipment is widely applied in precision weighing sensor factories, electronic component workshops.

Temperature Laboratory

The Temperature Laboratory of Shenyang Longteng Electronics is a dedicated quality control laboratory that guarantees the core accuracy and environmental adaptability of precision balances. All series of precision balances undergo systematic high and low temperature durability simulation tests here before delivery. After days of cyclic calibration and verification under alternating high and low temperature environments, the laboratory strictly controls the temperature interference on weighing accuracy. The measurement data deviation is controlled within 2 scale divisions per 1℃ temperature fluctuation. Eliminating temperature drift interference through stringent environmental adaptation tests, it fully stabilizes the full-range weighing performance of equipment. This ensures every factory-calibrated balance delivers outstanding environmental adaptability, stable measurement and reliable data, laying a solid quality foundation for high-precision metering applications in various industries.

Temperature Compensation & Time Drift Technology

Shenyang Longteng Electronics masters industry-leading temperature compensation and drift compensation core technologies, which are fully equipped on all series of our precision balances. Supported by rigorous high and low temperature environmental test data from professional laboratories, the equipment can sense real-time ambient temperature changes and automatically correct measurement errors caused by temperature drift, zero drift and span drift. Adopting accurate dynamic compensation algorithms, it effectively suppresses data fluctuations under complex working conditions. The measurement deviation is strictly controlled within 2 scale divisions per 1℃ temperature change. This technology greatly improves the environmental adaptability and long-term measurement stability of the balances, ensuring consistent high-precision metering performance of equipment under variable temperatures and long-term continuous operation scenarios.

Fine-tuning Room

The Fine Tuning Room serves as our core laboratory for process commissioning and performance calibration. It is the critical workshop where semi-finished electromagnetic force weighing sensor components are processed into qualified high-precision products for analytical balances.
