As the founding enterprise of stone wire saws, Pinhe Precision Technology has undergone more than six years of research and development. The equipment has been iterated to the ninth generation, with more than fifty patents, including more than twenty invention patents and two software copyrights, avoiding subsequent intellectual property disputes and reserving the rights to prosecute infringing enterprises. Pinhe Precision has always been based on continuous innovation and upgrading, constantly increasing investment in research and development, and establishing a strong R & D team. There is a lot of room for future equipment upgrades. If it is just copying, it is difficult for the equipment to make progress in iterations, and it is difficult to solve problems when problems occur.
