UNISIG USC-3M-BTA HORIZONTAL MACHINING CENTER

Technical Description

The UNISIG USC-3M-BTA Horizontal Machining Center is a high-capacity 5-axis CNC machine designed for complex deep hole drilling and milling operations, ideal for heavy and large workpieces up to 66,615 lbs. It features a horizontal spindle equipped with a robust CAT 50 (optional SK50) taper spindle running at speeds up to 4,500 RPM with a power rating of 27 HP (optional 34 HP) for versatile machining capabilities. The machine’s table measures 78.7" x 63.0" and supports a rotary B-axis with 360,000 position increments, alongside a 45° A-axis rotation, enabling precise multi-axis machining. The travel ranges are 122" (X), 68.9" (Y), and 51.2" (Z), supporting large-scale workpieces. An optional automatic tool changer (ATC) accommodates up to 40 tools, maximizing productivity. The USC-3M-BTA combines deep hole gundrilling with milling in a single setup, enhancing manufacturing efficiency, particularly in mold making, energy, and heavy industry sectors. Its rigid design, accurate geometric alignment verified by granite standards, and flat-floor installation contribute to superior accuracy, reduced setup time, and ease of integration into production environments. With a fully enclosed machining envelope, it supports both oil and water-soluble coolants. The machine’s structural strength and advanced control system make it well-suited for large, heavy machining tasks requiring deep drilling and milling with precision and reliability.
