The ALL NEW Closed Bridge Style High Speed Vertical Machining Center

Many companies manufacture bridge style vertical machining centers, but only Amera-Seiki has the ALL NEW Closed Bridge High Speed Vertical Machining Center with its exclusive features.

Unique Designs

The Amera-Seiki VCB-1837 is designed to take up where conventional vertical machining centers leave off. Our unique closed bridge structure was specifically developed to provide the utmost in strength and stability. This solid configuration provides 5 times the structural rigidity of a typical ‘C’ frame design. Unlike traditional models, where travels are limited by spindle to column distance, our design offers Y-axis stroke in excess of 51” with no inherent deflection under load.

Our thick walled Meehanite cast iron construction provides high stability during heavy cutting as well as high speed conditions. The base casting is extra wide, providing a rock solid machine structure with high quality roller-type linear guide ways positioned for maximum stability. Our ‘closed bridge’ style machine typically weighs in at 33% more than conventional vertical machining center designs. The entire machine structure was designed for optimum strength, vibration dampening and rigidity utilizing finite element analysis (FEA).


Closed Bridge Vertical Milling Machines

Amera-Seiki’s VCB closed bridge vertical milling machines:


  • By enclosing the bridge, this vertical milling machine is five times more rigid than a traditional "C-Frame" style VMC.
  • This design allows for over 51 inches of Y-Axis travel! That kind of travel is just not available on a traditional "C-Frame" VMC.
  • Need high speed cutting? We have spindle speeds up to 24,000 RPM!
  • We can offer either CAT 40, CAT 50, HSK and Capto taper options!
  • Many more options to choose from including a fourth axis table.

“We have multiple machines by Amera-Seiki and have had them for many years. They have required very little maintenance and we’ve experienced very little down-time, compared with other machine brands.”
