2021 MILLTRONICS RH33 VERTICAL MACHINING CENTERS

Technical Description

The 2021 MILLTRONICS RH33 is a 3-axis vertical machining center from Milltronics Manufacturing, representing an extended-capacity model in the RH column series designed for large-part machining in aerospace, mold and die, defense, and heavy contract manufacturing applications. The RH33 features a 86 x 32 inch T-slotted work table within a 78 x 33 x 28 inch X/Y/Z machining envelope, providing substantial capacity for large mold bases, structural components, and multi-part production fixtures exceeding the capacity of the RH30 platform. The 24 HP continuous-duty spindle motor (17.9 kW) operates through a CAT-40 spindle taper at speeds up to 8,000 RPM, delivering the sustained cutting power needed for aggressive steel and cast iron machining across the extended axis range. A 24-station automatic tool changer manages diverse tooling requirements through complex multi-step programs. Maximum table load of 3,500 lbs supports heavy workpieces and large fixture setups. The Milltronics Centurion 8 CNC control provides conversational and G-code programming with rigid tapping, tool-life management, and the manufacturer's production-optimized programming interface in a modern Windows-based architecture. At approximately 15,000 lbs, the RH33 delivers a robust cast iron platform with vibration damping and thermal stability appropriate for precise large-part machining. The RH33 is a practical choice for North American shops requiring a domestically manufactured, large-envelope VMC with proven Milltronics build quality, accessible support, and a modern CNC control platform suited to complex production requirements.
