大塚製作所 List of Products and Services

Our company operates five jig borers. As automation through machining centers has become mainstream, it is extremely rare for a company to possess this many jig borers nationwide. In recent years, the positioning accuracy of machining centers has approached that of jig borers, but they cannot escape the effects of aging, and their positioning accuracy inevitably deteriorates. Regarding sliding surfaces, one of the significant features of jig borers is that technicians can manually grind them to a precision of one micron, achieving a nearly flat surface that allows for smooth sliding. ■ Owned Jig Borers - Precision jig boring machine: 7CM (Mitsui Seiki) - 1 unit - Optical jig boring machine: 6B (Mitsui Seiki) - 2 units - Optical jig boring machine: 4B (Mitsui Seiki) - 2 units *For more details, please download the PDF document or feel free to contact us.
