What It Does

This machine is used for:

• Precision horizontal boring of holes or bores

• Facing large surfaces

• Milling slots, pockets, or profiles on heavy parts

• Drilling or tapping deep holes

• Thread boring and taper boring

• Line boring of large components like housings or castings

Its horizontal spindle orientation and movable column/table design allow for multi-axis machining of very large and complex workpieces.
