Overview
The Mazak VTC-300C is a vertical traveling column machining center designed for long workpieces that do not fit on conventional C-frame VMCs. The traveling column design keeps the table stationary while the spindle head moves along the X-axis, meaning the machine footprint stays constant regardless of axis position and heavy workpieces remain fixed during machining.
The VTC-300C provides travel of 2,000 x 760 x 660 mm (78.7 x 29.9 x 26.0 in). The nearly 80 inches of X-travel combined with 30 inches of Y-travel gives the machine a work envelope that handles long structural parts, multiple-part fixtures, and large plate work. The fixed table measures 2,500 x 760 mm (98.4 x 29.9 in) with a load capacity of 3,000 kg (6,614 lb).
The BT 50 spindle turns at 10,000 RPM with 30 kW (40 hp), providing the torque and tool clamping force needed for heavy roughing in steel, cast iron, and titanium. The 50-taper matches the machine's intended duty cycle: production-rate material removal on large, heavy parts. A 30-tool arm-type ATC handles the BT 50 tooling, with options for expanded magazines.
The machine is built on a rigid cast iron base with roller guides across all axes. The traveling column runs on hardened guideways for consistent accuracy across the full X-stroke. The MAZATROL SmoothG CNC manages all axis coordination with both conversational and G-code programming.
New VTC-300C machines run $200,000-$280,000 depending on configuration. The machine competes with the Okuma MB-8000H, DMG Mori DMF 260, and Haas VF-10. For shops machining long parts in steel and cast iron, the VTC-300C offers the combination of traveling column convenience and BT 50 cutting power.

Strengths & Limitations
Strengths
- 2,000 mm (78.7 in) X-travel with traveling column design handles long parts without the workpiece moving during machining
- BT 50 spindle with 30 kW (40 hp) provides the torque for aggressive roughing in steel, cast iron, and titanium
- 3,000 kg table load supports heavy workpieces and large fixture plates without concern for weight-induced axis forces
- Fixed table eliminates the dynamic load issues that affect moving-table machines when cutting heavy workpieces
- Wide 760 mm Y-travel enables side-by-side part fixturing and access to wide workpiece features
- Constant machine footprint regardless of X-axis position simplifies shop floor layout planning
Limitations
- Traveling column design is inherently less rigid than a fixed-column machine at full X-axis extension
- 10,000 RPM BT 50 spindle limits high-speed aluminum work; shops needing speed should consider BT 40 VTC models
- Large footprint and 12,500 kg machine weight require substantial floor space and foundation preparation
- Starting at $200K, the VTC-300C is a significant investment over C-frame VMCs with similar X-travel

Frequently Asked Questions
01
New VTC-300C machines run $200,000-$280,000 depending on options. Through-spindle coolant, expanded magazines, probing packages, and chip management systems push the price toward the upper range. Used VTC-300C machines from 2010-2018 sell for $80,000-$150,000.
02
In a traveling column machine, the table stays fixed and the spindle moves. This means heavy parts do not move during machining (better accuracy on large workpieces), the floor space stays constant regardless of axis position, and the table can support heavier loads since it does not need to accelerate.
03
The VTC-530C offers longer X-travel (2,500 mm vs 2,000 mm) and a larger table. The VTC-300C is the smaller, more affordable entry into the VTC traveling column lineup. Both use BT 50 spindles and traveling column architecture.
04
Yes. The 2,500 x 760 mm fixed table with 3,000 kg capacity is designed for multi-part fixturing. Many shops run two or three parts side by side, reducing per-part setup time significantly.
