Multi-Axis Efficiency for Modern Manufacturers

Machine Information

Miyano BNX51/65MSY

The Miyano BNX51/65MSY is a next-generation multi-axis CNC turning center, engineered for high-efficiency production of complex parts from bar stock.

Designed for flexibility, it supports bar diameters of up to 51 mm or 65 mm, depending on the variant—ideal for Indian manufacturers serving automotive, aerospace, and valve/hydraulic sectors.

This machine features two spindles, a Y-axis turret with 12 stations, and live tooling for full turning and milling in one setup. The main and sub spindles can work in tandem, enabling complete front-and-back machining without manual intervention, drastically cutting cycle time.

What makes the BNX series special is its space-saving, high-speed performance combined with advanced tooling and chip control features. The Y-axis (±35 mm), powerful milling drive, and compact footprint make it a great fit for Indian companies upgrading from single-turret machines to more capable, multitasking equipment.

With LFV chip-breaking technology available as an option, Indian shops working with aluminum, stainless steel, or high-tensile materials can enjoy tangle-free machining and longer tool life—critical for consistent production.

The BNX51/65MSY balances advanced capability with practical usability, offering high ROI for Indian manufacturers who want to step into the next level of smart, multi-axis machining.
