MC Machinery Systems, Inc. MC-4000 VERTICAL MACHINING CENTER

This vertical machining center features a 12.6" x 17.7" table supporting up to 440 lbs of workpiece weight, optimized for medium-duty precision machining. The spindle is vertical with a BIG Plus CAT-40 taper, delivering up to 15,000 RPM and rated at 15 HP continuously (20 HP optional) for robust cutting performance. The BIG Plus dual contact spindle system simultaneously engages the taper and spindle face, significantly enhancing rigidity, reducing tool deflection, improving surface finish, and extending tool life by minimizing axial tool movement and cutting vibration. The machine uses a 48-tool automatic tool changer (ATC), facilitating efficient operation without pallet changer capability. It has a 3-axis configuration (X, Y, Z) with rapid traverse rates of 1,890 inches per minute for each axis, allowing fast positioning and high productivity in milling, drilling, and boring tasks. Although no rotary or U axis support is provided, the design is well-suited for high-precision metalworking in industries requiring tight tolerances. The BIG Plus system compliance with ASME, JIS, and DIN standards ensures interchangeability and consistent spindle-toolholder fit, translating to superior machining accuracy and repeatability. This machining center thus offers a balance of speed, rigidity, and tooling capacity for complex vertical CNC milling operations.
