Mazak VCC-2000

In a conventional VMC, the spindle head moves in X and Y while the table moves in a third axis. At large scales (over 1,500 mm X-travel), moving a large, heavy table becomes impractical, so large-format VMCs use a traveling column design where the column and spindle move along the X-axis while the table remains stationary. This enables very large X-axis travels with better structural rigidity and simpler workpiece fixturing since the table does not move during machining.

The VCC-2000 can machine workpieces up to 2,000 mm in length (X-axis), 1,000 mm in width (Y-axis), and 700 mm in height (Z-axis clearance), with a maximum weight of 3,000 kg. In practice, workpiece height is limited to the Z-axis travel minus the tool length -- typically 500-600 mm maximum practical part height for most programs.

With the optional 15,000 RPM high-speed spindle, yes. Aerospace aluminum machining typically requires 10,000-20,000 RPM for optimal surface finish and material removal rates with carbide tooling. The standard 6,000 RPM CAT 50 spindle is more optimized for steel and cast iron roughing. Shops primarily machining aerospace aluminum should specify the high-speed spindle option at time of order.

A gantry machining center uses a fixed bridge over a moving table and offers superior rigidity for very large, very heavy workpieces (often 5,000-50,000 kg). The VCC-2000 is a more economical alternative for long but lighter workpieces (up to 3,000 kg) where gantry machine cost is not justified. If your parts consistently exceed 3,000 kg or require more than 2,000 mm in multiple axes simultaneously, a gantry machine is the more appropriate choice.

At 30,000 kg, the VCC-2000 requires an engineered foundation. Mazak provides a site preparation document with specific load distribution requirements. Most installations require a reinforced concrete pad with leveling pads and vibration isolation. Budget $30,000-$80,000 for site preparation depending on existing slab conditions.
