Mitsui Seiki J12/J16 jig borers combine large capacity with high precision

Mitsui Seiki USA has introduced the J12/J16 jig borer series, which combines large capacities and high precision to meet the increasing need for accuracy for machining workpieces such as molds and castings.
The machines have a Y-axis stroke of either 1,250 mm or 1,600 mm, with standard table sizes of 2,400 mm by 1,250 mm or 2,900 mm by 1,600 mm.
The machines’ structures create a table lateral movement accuracy of 2.5 µm or better, the company states. The Z-axis guide system is restrained on four sides to maximize rigidity and reliability, and dual ball screws help ensure stable feed motion.
For precision holemaking applications, XY interpolation enables the machines to carry out high-precision contouring by using an end mill instead of a boring tool, eliminating the need to manually adjust a boring tool to accurately finish the hole diameter. Pitch accuracy is within 5 µm even for large-pitch holes.
The machines have a 12,000-RPM, 50-taper spindle and ATC capacity of 60 tools. Additional options such as quill spindle, increased work capacity, as well as automation features are available.
