Gromax 4HU VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a precision work table measuring 52 inches in length by 12.6 inches in width, accommodating workpieces up to 300 pounds. The vertically-oriented spindle utilizes an ISO #50 taper with a maximum rotational speed of 1,500 RPM, powered by a 10 horsepower motor rated for continuous 30-minute operation. The machine provides three axes of motion: the Y-axis offers 9.5 to 10 inches of travel, while the Z-axis delivers 11.8 to 12.6 inches of vertical traverse, enabling precision plunge cuts and drilling operations typical of conventional vertical mills. Manual tool changing accommodates a single tool at a time, making this unit ideal for job shop and tool room applications requiring versatility over high-speed production. The substantial spindle taper and moderate RPM rating make this machine well-suited for heavy-duty milling, boring, and drilling operations on ferrous materials. The compact table width of 12.6 inches and extended length of 52 inches optimize the work envelope for long, narrow components while maintaining rigid support and stability during machining. This configuration represents a traditional vertical knee mill design, emphasizing precision, durability, and manual control, making it particularly valuable for prototype development, maintenance work, and specialized machining tasks requiring operator flexibility and control rather than fully automated production cycles.
