Johnford - Roundtop Machinery Company DMC-3100HN VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a robust table measuring 125.9 inches in length by 43.0 inches in width, capable of supporting workpieces up to 13,200 lbs, making it ideal for heavy-duty and high-precision machining applications. The spindle is vertically oriented with an HSK-63A taper, supporting high-speed operations up to 24,000 rpm (standard) or 18,000 rpm (optional), and delivers 31 hp (30-minute rating) with an optional upgrade to 56 hp for demanding tasks. Tooling is managed by an automatic tool changer (ATC) with a standard capacity of 24 tools, expandable to 120 tools for increased flexibility. The machine provides rapid tool-to-tool change times, ensuring efficient production cycles. The three-axis configuration (X, Y, Z) offers extensive travel ranges: 120 inches on the X-axis, 43 inches (optional 51 inches) on the Y-axis, and 32 inches on the Z-axis. Maximum feed rates and rapid traverse speeds reach 590 inches per minute across all axes, enabling fast and accurate positioning for complex milling operations. The combination of high load capacity, high-speed spindle, versatile tooling, and generous axis travels makes this machining center suitable for a wide range of industrial applications, including aerospace, automotive, and mold manufacturing, where precision, reliability, and productivity are critical.
