New Product: Compact Universal Internal Grinding Machine 'STG-3NX'

Compact universal internal grinding machine 'STG-3NX' that achieves high precision and high productivity. *Test processing available.

The product, the compact universal internal grinding machine "STG-3NX," is a CNC internal grinding machine that enables high-precision and high-efficiency processing despite its compact size. Since its launch in 2009, the "STG-3NX" has received high praise as a successor model to the small internal grinding machine "STG-3N," which is equipped with a 3-inch/4-inch chuck. It retains the advantages of space-saving, high rigidity, and low center of gravity structure while expanding the internal space by extending the stroke of the spindle base table, thereby improving workpiece loading and unloading as well as in-machine measurement operations. Additionally, it is equipped with a high-output, high-rigidity self-developed high-frequency spindle "H Series," contributing to the improvement of customer productivity through high-precision and high-efficiency processing. 【Features】 ■ The stroke of the spindle base table is extended by 33%, expanding the internal space. ■ Achieves high-precision and high-efficiency processing. ■ Improved operability based on ergonomic layout. ■ Equipped with FANUC NC device (FIELD system compatible). *To evaluate the capabilities of the STG-3NX, we offer test processing of specified workpieces free of charge in principle.
