MIYANO BNJ-51SY2 HORIZONTAL MACHINING CENTER

Technical Description

The MIYANO BNJ-51SY2 is a highly capable horizontal machining center designed for precision turning and milling operations. It features a single main spindle with a maximum turning diameter of 6.000 inches and turning length of 3.930 inches, accommodating workpieces with a maximum bar diameter of 2.000 inches. The main spindle operates at up to 5,000 RPM with 15 HP power, while the sub spindle offers 7,000 RPM and 7.5 HP, enabling high-speed secondary operations. Equipped with a six-axis system, it provides comprehensive tool positioning and movement with X, Y, and Z travels of 6.500, 3.140, and 9.690 inches respectively. The machine offers dual tool carriers; the main turret holds up to 12 turning and rotary tools, each rotary tool rated at 3.3 HP and capable of speeds up to 6,000 RPM. The back turret provides an additional six turning and rotary tools, also rated at 3.3 HP and 6,000 RPM rotary speed, enhancing multi-process flexibility. This configuration supports complex machining cycles with simultaneous turning and milling, improving throughput and accuracy. The robust spindle power and rotation, combined with multiple tool stations and comprehensive axis travels, make the BNJ-51SY2 suitable for medium-sized precision components in automotive, aerospace, and general manufacturing sectors. Its combination of speed, power, and tooling versatility positions it as an efficient solution for high-mix, high-volume production environments.
