Frequently Asked Questions

What is a 4-axis swing-head?
A spindle head that swivels on two axes, so it can approach a part from many angles and machine complex curved surfaces without re-clamping.
Which parts suit the GA-GFU3755?
Large curved and multi-angle components — aerospace skins, mold inserts, impeller housings and similar free-form work.
How does it compare to a 5-axis machine?
It adds multi-angle reach via the head rather than a full rotary table; ideal for large parts where a trunnion table is impractical.
