Johnford - Roundtop Machinery Company DMC-2600SHN VERTICAL MACHINING CENTER

This vertical spindle CNC machining center features a robust work table measuring 106.2 inches by 59 inches, capable of supporting workpieces weighing up to 22,000 pounds. The machine is equipped with an HSK-63A taper spindle, the industry standard for moderate to high-speed applications, delivering maximum speeds of 24,000 RPM with 31 horsepower, or alternatively 18,000 RPM with 56 horsepower for heavy-duty cutting operations. The HSK-63A design includes drive slots for superior torque transmission, making it ideal for demanding machining tasks requiring significant cutting force. The machine utilizes an Automatic Tool Changer (ATC) with capacity for 24 tools, expandable to 120 tools for enhanced flexibility in complex production runs. Three-axis control provides comprehensive movement capabilities: 102 inches of X-axis travel, 70 inches of Y-axis travel, and either 32 or 42 inches of Z-axis travel (optional), all with rapid traverse rates of 472 inches per minute. This combination of generous work envelope and rapid positioning enables efficient part production across diverse manufacturing applications. The spindle's hollow 1/10 taper design ensures consistent contact with the spindle wall during high-speed rotation, maintaining positioning accuracy and precision. The machine's substantial power capacity, flexible spindle configurations, and large tool magazine make it suitable for production environments requiring versatility, from moderate-speed heavy cutting to higher-speed precision finishing operations across various workpiece geometries and materials.
