Johnford - Roundtop Machinery Company DMC-2100HN VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large worktable measuring 86.6" (L) x 59.0" (W), designed to support a maximum workpiece weight of 13,200 lbs, making it suitable for heavy-duty machining tasks. It is equipped with a vertical spindle with an HSK-63A taper, capable of speeds up to 24,000 RPM standard, and an optional configuration providing 18,000 RPM. The spindle power is rated at 31 HP for 30-minute operation, with an optional boost to 56 HP for demanding applications. Tool handling is managed via an automatic tool changer (ATC) with a standard capacity of 24 tools, expandable up to 120 tools, enabling efficient workflow in multi-tool machining processes. The machine operates on three axes (X, Y, Z) with travel distances of 81" along X, 43" (optional 51") along Y, and 32" along Z. All axes support rapid traverse rates up to 590 inches per minute, ensuring fast positioning and reduced cycle times. Notably, the tool change chip time is zero seconds, indicating a highly optimized ATC system for minimal downtime. This machine delivers robust performance, combining large-scale workpiece capacity, high spindle power, and extensive tooling options, ideal for complex and heavy machining in industries such as aerospace, automotive, and heavy equipment manufacturing.
