The VARIAXIS i-Series is a highly versatile line of full, simultaneous 5-axis machining centers that performs multiple and complex curved surface machining on large, heavy workpieces in single setups.
The series falls within Mazak’s DONE IN ONE® concept by incorporating all processes from raw material input through final machining in just one machine. As such, the VARIAXIS machines reduce production lead times, improve machining accuracy and lower operating expenses.
VARIAXIS machines also offer high levels of productivity via an extremely fast, high-rigidity spindle design that can handle a wide variety of applications, from heavy-duty cutting to high-speed cutting of aluminum and other nonferrous material.
Mazak’s highly advanced MATRIX 2 CNC control brings increased ease of operation to these machines. Enhanced hardware and software functionalities within the control make it easy to use while also delivering high accuracy and increased productivity. Control hardware performance is much faster with higher processing speeds for small increment operation. Furthermore, a 5-axis spline interpolation function included in the control’s software provides smooth toolpaths from long block-by-block programs, easy tool vector control and shorter cycle times as well as superior surface finishes.
Optional two-pallet changers allow for continuous operation and for integrating the machines into PALLETECH Manufacturing Systems for full automation.

Roller Gear Cam Trunnion Table
Improves rigidity and accuracy
High-accuracy, continuous multiple surface machining and 5-axis simultaneously controlled machining are realized thanks to the A-axis and C-axes 0.0001° minimum positioning increment. The A-axis features a trunnion design to provide high rigidity for high accuracy machining. The table itself utilizes a roller gear cam which eliminates backlash to ensure high accuracy and high efficiency machining
Ball-Screw Core Cooling
Thermal management on the X-, Y-, and Z-axes
Temperature-controlled cooling oil circulates through the ball screw cores to ensure stable machining accuracy over extended periods of high speed operation.
A closer realization to Done-In-One
The rotary table (C-axis) is driven by a direct drive motor for both C-axis positioning and turning operation with a maximum spindle speed of 1100 rpm. Turning is performed with the A-axis in the 0 degree position or 90 degree position. Since the A-axis is rigidly clamped on a coupling in the 0 or 90 degree position for turning operations, high accuracy machining over extended periods of operation is ensured.
