Mazak Variaxis i-800 Machining Center

Mazak introduces the VARIAXIS i-800 Machining Center with full, simultaneous 5-axis capabilities. The high-accuracy machine performs multiple and complex curved surface machining on large, heavy workpieces in single setups.

The Variaxis i-800 falls within Mazak’s done-in-one concept as it incorporates all processes from raw material input through final machining in just one machine. As such, the Variaxis i-800 reduces production lead times, improves machining accuracy, and lowers operating expenses. Furthermore, it can tackle a wide range of applications, from heavy-duty cutting to high-speed cutting of aluminum and other nonferrous materials.
   
With a Y-axis travel of 33.46” (850mm) and X-axis of 28.74” (730mm), the Variaxis i-800 easily accommodates workpieces measuring up to 39.37” (1,000mm) in diameter and 19.69” (500mm) high. Its roller gear cam-driven rotary/tilt table, with 360° of rotation in the C-axis and +30° through -120° of tilt in the A- axis, is supported at both ends and provides stable high-accuracy machining. 

The Variaxis i-800 comes standard with a fast, high-rigidity 10,000rpm, 40hp, 50-taper spindle with a compact nose design that helps increase the machine’s Z-axis stroke to 22.05” (560mm) and overall machining stability by allowing for the use of shorter tools. An optional 18,000rpm spindle is also available.

A reliable cam-driver tool changer enables the Variaxis i-800 to meet the machining requirements of a wide variety of workpieces thanks to its tool magazine capacities, ranging from the standard 30 tools up to the maximum of 120 tools.

Speed and increased productivity are gained through the fast 1,654ipm (42m/minute) rapid traverse rates of the machine’s X-, Y-, and Z axes, as well as from its use of Mazak’s MX Hybrid Roller Guide System in those axes. The MX Hybrid Roller Guide System delivers levels of durability and reliability that result in long-term accuracy. This innovative way system increases vibration dampening, extends tool life, handles higher load capacities, and eliminates tramp oil in the coolant by utilizing a greener grease-based lubrication system.

The Variaxis i-800 features Mazak’s new Matrix 2 CNC control. Within the control are both enhanced hardware and software functionalities that make the control 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.
