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

This vertical machining center features a large table size of 86.6" x 59.0" capable of supporting workpieces up to 22,000 lbs, making it suitable for heavy-duty machining tasks. It operates with a vertical spindle using an HSK-63A taper, optimized for high precision and rigidity in tool holding. The spindle reaches a maximum speed of 24,000 RPM with an optional top speed of 18,000 RPM, powered by a 31 HP motor rated for 30 minutes, with an optional increase to 56 HP for enhanced cutting power. The machine is equipped with an automatic tool changer (ATC) that holds 24 tools as standard, expandable up to 120 tools, supporting efficient and uninterrupted machining operations with zero tool change chip time. It supports three axes of movement with travels of 83" on X, 70" on Y, and either 32" or optionally 42" on Z, all featuring a rapid traverse rate of 472 inches per minute, allowing swift positioning and cycle times. The combination of a high-capacity worktable, high power spindle, fast tool changing, and extensive axes travel makes this vertical machining center highly versatile for complex milling, drilling, boring, and tapping in heavy, large-format workflows across aerospace, automotive, and heavy machinery industries. The HSK-63A taper ensures strong torque transmission and superior spindle-tool engagement suitable for demanding applications requiring precision and robustness.
