VB Series | JTEKT Machinery North America

VB Series

The VB Series is a fixed rail bridge machining solution built to take on the most demanding heavy-cutting applications. Engineered for strength and stability, it features heavy-duty Roller LM Guides on the X and Y axes and robust Box Ways on the Z axis. A highly efficient hydraulic counterbalance system ensures smooth operation while minimizing power consumption. At its core, the 35 HP, two-speed geared head delivers exceptional torque, making it ideal for tough cuts, extending tool life, and optimizing overall machining performance.

VB 315 skeleton

Rigid Structural Design

The VB Series is built on a foundation of strength and stability. Each model is engineered with a massive, single-piece Meehanite® cast iron base paired with dual bridge columns—creating a rigid, unshakable structure capable of withstanding the most demanding heavy-duty cutting environments. This design minimizes deflection, absorbs vibration, and ensures long-term dimensional accuracy, even during aggressive machining operations.

At the heart of the platform is a precision-ground cast iron table, carefully finished to deliver superior flatness and parallelism across the entire surface. This guarantees consistent accuracy when machining large workpieces, providing manufacturers with confidence in repeatable high-precision results.


Spindle VB

High Performance Spindle

The VB Series spindle is built for precision and power. A robust cast iron headstock houses a 6,000 RPM, two-speed geared-head BigPlus® spindle designed for exceptional revolution accuracy and superior vibration dampening. With large-diameter bearings and a CAT50 taper, the spindle delivers increased rigidity and handles heavy-load machining with ease.

Key Specifications:

  • Spindle Speed: 10 – 6,000 min⁻¹
  • Spindle Taper: BVC50
  • Spindle Motor: 22 kW (30 HP) continuous / 26 kW (35 HP) 30 min.
  • Max Torque (100% Duty): 626.2 Nm (461 ft-lb)
  • Spindle Diameter (Front Bearing Bore): Ø100 mm (3.9 in)

VB roller Guide

Heavy-Duty Roller Guideways

The VB Series is designed to deliver unmatched machining stability through the use of heavy-duty precision linear roller guideways on the X and Y axes, combined with a robust boxway Z axis. This advanced configuration provides exceptional dynamic accuracy, enabling smooth, precise movement even during the most demanding cutting applications.

The linear roller guideways are engineered to handle high loads with minimal friction, ensuring consistent performance and extending machine life. When paired with the rigid boxway Z axis, the result is a platform that not only exceeds industry standards for quality and precision but also maintains stability under heavy table loads.
