Fixed Head

*NEW* Miyano BNE65ATC CNC Fixed Head
Automatic Tool Changer and Programmable B Axis

At the heart of the BNE-65ATC CNC Fixed Head is its twin Y-axis configuration, with one Y-axis assigned to each turret. This enables true simultaneous machining of complex components, allowing for superimposed operations and three-tool simultaneous cutting with exceptional stability and efficiency.

A key feature of the ATC model is the integrated 24-tool carousel, positioned at the rear of the machine. This system enables rapid tool changes for live tooling operations on the upper turret. This achieves an impressive chip-to-chip time of just 8.9 seconds. The ATC unit supports S20T-BT shank tooling, providing the flexibility to utilise a wide range of tools. This includes drills, end mills, and face mills.

Enhancing this capability further, the upper turret is equipped with a tool spindle that can be indexed in the B-axis, enabling stable and rigid full 5-axis machining. This functionality allows drilling and tapping at any angle, significantly expanding machining versatility. When combined with the ATC system, the BNE-65ATC can efficiently handle a diverse range of complex workpiece geometries.

Bringing together high-speed performance, advanced tooling capability, and exceptional flexibility. The BNE-65ATC represents a major step forward in fixed head machining. It delivers the performance and adaptability required for today’s high-precision, high-efficiency manufacturing environments.
