OKUMA & HOWA MILLAC 415V VERTICAL MACHINING CENTER

Technical Description

This CNC machine features a **work envelope** with X-axis travel of 22 inches, and Y- and Z-axis travels of 16.14 inches each, providing ample movement for versatile machining tasks. The **T-slotted work table**, measuring 27.56 by 15.75 inches, supports a maximum load capacity of 771 lbs, enabling secure fixturing of heavy workpieces. Its **spindle drive motor** is powered at 10 hp, delivering a spindle speed range from 120 to 8000 rpm through a NST 40 taper bore, suitable for a broad spectrum of cutting operations. The machine is equipped with a **16-station Automatic Tool Changer (ATC)** featuring MAS403-BT40 style tool holders and MAS407 P40T-1 pull studs, enhancing productivity by minimizing tool changeover time to just 1.8 seconds. The ATC supports electronic random access tool selection, accommodating tools up to 3.54 inches in diameter with adjacent tools, or 4.53 inches without, tool lengths up to 9.84 inches, and weights up to 11 lbs. The machine operates on a 200-volt three-phase power supply, rated at 18 KVA and 52 amps, ensuring sufficient energy availability for demanding machining cycles. This robust configuration is designed to balance high precision, productivity, and flexibility for complex milling applications, especially those requiring a large work envelope, fast automated tool changes, and heavy-duty spindle capacity.
