This time, I will introduce high-precision processing of spheres.
Industry: Machine Tools Material: S45C Lot: 1 piece Accuracy: 2/100 Usage: Seismic isolation device parts Machining Equipment: Composite NC lathe, horizontal machining center Product Size: Outer diameter Φ150, Length 520 The machining process involves quenching and tempering material - lathe - machining. The quenched and tempered material is procured from a partner company. During the reverse R machining on the lathe, care was taken to ensure that the tool did not collide. The tolerance for the sphere is strict at 2/100. In addition to measuring only in the radial direction, multiple diagonal measurements including the Z direction were taken in conjunction with the lathe machinist and inspection as the machining progressed. In machining, the shaft-shaped part was fixed with a V-block, and the machining was carried out. However, due to poor weight balance and instability, the flat part of the sphere was supported with a screw-type locator while parallel alignment was performed on the end face during machining.

basic information
Industry: Machine Tools Material: S45C Lot: 1 piece Accuracy: 2/100 Application: Seismic isolation device parts Machinery Used: Composite NC lathe, horizontal machining Product Size: Outer diameter Φ150, Length 520 The processing steps are: heat-treated material (quenching and tempering) - lathe - machining. The heat-treated material is procured from a partner company. During the reverse R processing on the lathe, care was taken to ensure that the tool did not collide. The tolerance for the sphere is strict at 2/100. Measurements were taken not only in the radial direction but also in multiple diagonal directions including Z, with the lathe operator and inspector measuring as processing progressed. In machining, the shaft-shaped part was fixed using a V-block, and processing was carried out. However, due to poor weight balance and instability, the flat part of the sphere was supported with a screw-type locator while parallel alignment was performed on the end face during processing.

The quenched material is procured from a partner company. During the reverse R machining on the lathe, care was taken to ensure that the tool did not collide. The tolerance for the sphere is strict at 2/100. Measurements were taken not only in the radial direction but also in multiple diagonal directions including Z, while progressing with machining and inspection alongside the lathe operator. In machining, the shaft-shaped part was fixed using a V-block, and machining was carried out. However, due to poor weight balance and instability, the flat part of the sphere was supported with a screw-type locator while parallel alignment was performed on the end face during machining.

Company information
We have NC lathes, vertical machining centers, horizontal machining centers, surface grinders, cylindrical grinders, internal grinders, vertical grinders, and three-dimensional measuring machines in-house, allowing for consistent production from medium-sized round workpieces to large-sized ones (Φ200 to Φ800) using our in-house equipment. We can also handle smaller workpieces ranging from Φ50 to Φ300. We are also considering machining from solid materials for prototype parts, as well as processing difficult materials such as titanium and Stellite. Common inquiries often involve flanges with precision requirements for coaxiality, concentricity, roundness, perpendicularity, and parallelism around 0.005 mm. Items such as stator sleeves used in motors, which require thin walls and lead groove machining, can be finished with high precision using our vertical grinding machines. We can propose ways to reduce the management workload for your ordering personnel, so please feel free to consult with us.
