⚙️ Key Features

• The machine adopts a four-column frame structure with dual space. The speed control system for both the pulling and pressing actions uses a servo speed control system and servo motor, ensuring stable and reliable performance with mechanical protection features such as overcurrent, overpressure, and overload protection.
• The transmission part uses an arc-shaped synchronous toothed belt, with precision ball screw drive, ensuring smooth transmission, low noise, and high efficiency.
• The universal joint employs a cross-pin structure and includes an angle-limiting function. This design facilitates sample clamping, ensuring the test’s concentricity, and effectively eliminates the impact of irregular samples on the sensors.
• Equipped with a specialized ring stiffness deformation measurement device, the machine provides more accurate deformation results.
