The BNA42GTY CNC Fixed Head combines gang tool speed with turret flexibility for high-efficiency, complex machining.
It features two spindles, a Y-axis turret, and a high-speed gang tool slide for simultaneous front and back machining.
Advanced functions like balance cutting, pinch milling, and 3-axis overlapping improve productivity and cycle time.
LFV Technology enhances chip control, especially with difficult materials and deep-hole drilling. LFV also reduces swarf build-up and extends tool life, ensuring consistent, clean machining performance.
A 4-position tool holder for back machining allows up to 45 tools to be mounted. This expands the machine’s flexibility for complex components and quick changeovers.
The BNA-42GTY CNC Fixed Head delivers precision, speed, and reliability in a compact footprint.
