Description:
The Lucas 41 Precision Horizontal Boring Mill is a heavy-duty, precision-engineered machine tool built for boring, milling, drilling, and facing large and heavy workpieces. Manufactured by Lucas Precision, a leader in horizontal boring technology, the Model 41 is designed for accurate machining of large parts, such as molds, dies, castings, engine components, and structural frames.
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.
