H. H. ROBERTS TW-24L VERTICAL MACHINING CENTER

This vertical machining center features a #40 taper spindle with dual RPM capabilities of 8,000 standard and 12,000 optional, delivering 7.5 HP for versatile machining operations. The machine accommodates workpieces up to 660 lbs on a 34" x 18" work table, with optional support for rotary and index tables for enhanced flexibility. The 3-axis configuration provides 24" X-axis, 16" Y-axis, and 16" Z-axis travels, supporting rapid traverse rates of 1,400 IPM across all axes and maximum cutting feed rates of 400 IPM. An automatic tool changer manages 16 standard or 24 optional tools with impressive cycle times of 6 seconds for tool changes and 8 seconds including chip clearing, enabling efficient production workflows. The machine's modular design accommodates an optional 4th axis for rotational machining capabilities, while a dual-pallet changer option allows for continuous production with minimal downtime. Standard construction includes precision linear guideways and ball screws to maintain positional accuracy throughout extended machining operations. This machine is ideally suited for job shops and manufacturing facilities requiring precise multi-axis milling of mid-sized components across diverse material applications, from prototype development to production runs.
