1. High-volume production drilling of automotive engine blocks, transmission cases, and other parts.
2. Tapping and thread rolling on bolts, screws, and other fasteners.
3. Boring and reaming operations on precision parts such as gears, bearings, and shafts.
4. Thread milling, helical milling, and other milling operations on large components.
5. Facing, grooving, and profiling on tube and pipe, bar stock, and other long, cylindrical parts.
Overall, multi spindle heads are best suited for machining operations that require high-speed drilling, tapping, and boring of multiple holes on a range of materials, including steel, aluminum, brass, and cast iron.
