Abstract The medium size cylindrical grinder, which is one of our company’s main machine tools, has been fully remodeled to suit the needs of the customer, leading to the development of the G5i series grinder. The G5i series includes the GE4i (large variety/small lot type), the GL4i (medium variety/medium lot type), and GL5i (small variety/large lot type), which are composed of the same common components, such as a bed called the platform. The recently developed GE4i was designed under the concept of “a machine with which anyone can easily make high-grade monozukuri”, and answers customer needs for improved dimension accuracy through the reduction of thermal strain, which is the cause of dimensional change. Furthermore, the GE4i is a grinder that not only achieves stable accuracy including improved circularity, surface and roundness, but also has enhanced operability and safety, as well as environmental friendliness.
