Vertical Bridge Mills

When you need a machine tool to process your mid to large size parts, look no further than Amera-Seiki. Our Vertical Bridge Mill line offers the strength and speed to make short work of your toughest jobs.

We start with massive Meehanite castings, annealed to eliminate deformation caused by internal warpage and stress. A quiet two-speed spindle, driven by a powerful Fanuc motor, offers a winning combination of high speed and torque.

Our fully sealed, immersion-type lubrication system with standard oil chiller circulates coolant and keeps the machine running cool at high RPM. The rigid ball screws and powerful servo drives assure smooth cutting.

Top Quality Vertical Bridge Mills

48 Machine sizes to choose from! Our VB Series bridge mills can handle very large work pieces with X-Axis travels from 2.2 to 8.0 Meters and Y-Axis travels from 1.4 to 4.2 Meters!
Our base castings are 25% heavier than our competitors. This provides greater structural rigidity to reduce harmonics or chatter.
Need to change heads automatically? We offer Automatic Head Changers with up to 10 head capacity so we can accommodate right angle heads, swivel heads, extension heads and many, many more.
Doing a complex piece and need 5-Axis Simultaneous machining? We can do it with Fanuc, Siemens or Heidenhain controls, with up to 24,000 RPM utilizing HSK tooling!
Have a taller workpiece? We offer a W-Axis to extend the vertical travel!

Equipment To Rave About

4.8/5 stars

James Roy,
Mavrik Manufacturing

We have many Amera-Seiki machines in our plant, and we purchased our first Amera-Seiki UTM-12 Coupling Solution over a year ago. We’ve been running 4½” API (8) round oil couplings and find this machine to be the best threading machine we have ever known!

Bill Awerkamp,
Awerkamp Machine Co.

It was simple. They had one (Amera-Seiki LT-50 CNC Lathe) coming in just like I wanted. I went and looked at it and, after their tech showed me how well-built it was, I bought it.

Thomas H. Addy,
Quality Engineering

The machine we wanted was too tall to fit into our building, but Amera-Seiki offered to customize the guarding so it would fit. No other machine company made this offer. We are very, very pleased with both machine and the customer service at Amera-Seiki!

Bill Awerkamp,
Awerkamp Machine Co.

Their tech came in and set it all up, explained it and let me do the test cut. (3 years later) we had a bad wreck that knocked the turret and headstock out of alignment which their man corrected in a few hours. We have had no other problems.

Chuck Lord,
Innovation Machining Corp.

Working with Amera-Seiki, you never have to worry if they’re trying to take advantage of you.

Bill Awerkamp,
Awerkamp Machine Co.

I would recommend the Amera-Seiki. It (A-S LT-50 Lathe) is built well and I could not find a better one for even close to what we paid. It’s a good machine.

Randy Sherbeyn,
Springfield INC. (Springfield Armory)

We’ve been an Amera-Seiki customer for 18 years. We have 15 Amera-Seiki machines.

Ford B. Cauffiel,
American Steel Products Company

Excellent quality and service. I would recommend Amera-Seiki machines to others.
