Mechanical Engineering is useful and inseparable from industry and industry. The production and manufacturing process entails converting raw materials into final items that meet required parameters while utilizing cutting-edge technologies. The stiffness, modulus of rigidity, and bulk modules are determined using a spring load testing machine in our project. A variety of inspection machines are utilized in the spring working business. Because the sector is broad and growing, several types of machinery are employed for various processes. The spring rolling machine in our concept is relatively simple to operate thanks to the use of a microcontroller and a digital display. This machine is used to perform several types of spring load tests on springs of varying diameters and lengths. This equipment has a wide range of applications. The building and operation of this machine are straightforward. Industries buy springs for their hydraulic valves, but they have a hard time evaluating the rigidity of the springs. We conceived and developed a digital spring stiffness testing machine after learning about the industry's challenges with spring testing. We can determine spring stiffness using only two parameters: load and deflection. The machine is designed to meet the needs of a company that manufactures various valves. As a result, a digital spring testing equipment has been designed to meet the needs of the organisation.
