Gbw-60b Computer Control Cupping Testing Machine

1.1. The cupping testing machine adopts an improved structural design that provides constant-speed control throughout the test. 1.2. The conventional hydraulic loading system has been replaced with a permanent servo-electric motor loading system. The hydraulic sensor has also been replaced with a high-precision dual sensor, improving the accuracy and repeatability of the penetration measurement. 1.3. The cupping-depth measuring system uses a high-precision grating displacement sensor with an indication error of no more than ±0.02 mm, improving the accuracy and controllability of the machine. 1.4. The hardware configuration and force-transmission system have been significantly improved. The machine is equipped with computer control for test operation, report generation, data storage, batch management, and curve plotting. 2.1. Maximum Test Force: 60 kN 2.2.
