Highly Repeatable, 5-Axis VMC for Hard-to-Cut Parts

A five-axis configuration with a tilting A-axis and full rotary C-axis make it possible to machine complex blade geometries, difficult-to-cut ceramics, and mold-and-die products.

MITSUI SEIKI USA will introduce the Vertex55X NEO high-performance vertical machining center with FANUC 31i-B5 Plus control for simultaneous, precision five-axis machining at IMTS, in the South building at booth 338700.

Designed to machine complex blade geometries, difficult-to-cut ceramics, and mold and die operations among others, the Vertex55X NEO offers five-axis configuration with a tilting A-axis and full rotary C-axis for more complete machining operations in fewer set-ups. This includes the use of shorter tools for those difficult-to-reach cavities and undercuts, and better finishes.

The machine’s ultra high-speed spindle capability - up to 30,000 RPM - helps to reduce polishing and lead times significantly, while at the same time offering advanced thermal stability and +/-0.001 mm positioning accuracy. The FANUC 31i-B5 Plus controller provides AI contour control and high-speed processing. Integrated automation options, probing technology and high-speed tool changing capabilities provide mold and die manufacturers with the capacity to achieve highly accurate parts to meet even the most difficult customer deadlines.

The Vertex 55X NEO features a table longitudinal stroke (X-axis) of 550 mm, table cross stroke (Y-axis) of 600 mm and spindle head vertical stroke (Z-ais) of 500 mm. Roller-type linear guide ways offer the high-rigidity necessary to maintain exceptional accuracy, precision and repeatability. An absolute linear glass scale indicates the exact position of the X/Y/Z axes for accurate repeatability while an absolute rotary Inductosyn scale performs the same function for the A and C axes. The machine automatically knows its exact position when it’s turned on in both instances.

Cutting feed and traverse rates range from 0.1-48,000 mm/minute on the X/Y/Z axes to a traverse rate of 40 RPM on the A (tilt) axis with a cutting feed of 30 RPM, on the C (rotary) axis. Manufacturers are now able to scale up their machining processes from slow and controlled feeds for high-precision finishing on those difficult-to reach sections such as cavities and deep pockets to the high-speeds required to efficiently rough out large blocks of material for precision contouring applications.

This newly introduced vertical machining center was designed to solve the main challenges faced by mold-and-die manufacturers: deliver complex high-precision parts of tough-to-machine materials with the highest degree of accuracy and repeatability within demanding lead times. Each Vertex55X NEO is fully customizable to meet customer needs.

“The Vertex55X NEO gives mold-and-die manufacturers the ability to machine complex geometries with exceptional accuracy and 30,000 RPM performance, significantly reducing polishing and lead times. It’s a platform built to help our customers deliver superior quality faster and more consistently,” stated Joe Farkas, national sales director, Mitsui Seiki USA.

Mitsui Seiki is not only been a leader in precision machine design and production but also in expertise. On Wednesday, Sept.16, 2026, from 9:00-9:55 am in Room W192-A, Mitsui Seiki director of sales - West Nathan Swartzbaugh will make a presentation: “Thoughtful Automation: High-Precision CNC Machining Processes Demand Extraordinary Reliability and Repeatability – Harnessing the Power of Data-Driven Analysis - and Perhaps AI – To Achieve The Perfect Part the First Time.”
