Mazak Multi-Tasking Vertical Machining Center

Mazak introduces the new Variaxis i-700 5-axis machine, which, in single setups, efficiently processes long workpieces and those requiring precision machined complex curved surfaces, such as on various aerospace, automotive, and marine components.  

The Variaxis i-700 is a full, simultaneous 5-axis Multi-Tasking vertical machining center that falls within Mazak’s done-in-one concept, as it incorporates all processes from raw material input through final machining into just one machine. As such, the Variaxis i-700 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 spacious Y-axis travel of 43.30” (1,100mm) and X-axis of 24.80” (630mm), the Variaxis i-700 easily accommodates workpieces measuring up to 33.46” (850mm) in diameter and 19.68” (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-700 comes standard with a fast, high-rigidity 12,000rpm, 30hp 40-taper spindle with a compact nose design that helps increase the machine’s Z-axis stroke to 23.62” (600mm) and overall machining stability by allowing for the use of shorter tools. An optional 18,000rpm spindle is also available.

The Variaxis i-700 comes with a reliable cam-driver tool changer. It is able to meet the machining requirements of a wide variety of workpieces thanks to its tool magazine capacities, from the standard 30 tools up to the maximum of 120 tools.

Speed and increased productivity are gained through the fast rapid traverse rates of the Variaxis i-700, as well as from its use of Mazak’s MX Hybrid Roller Guide System in the X-, Y- and Z-axes. The machine rapid traverses as fast as 2,362ipm (60m/minute) in the X- and Y-axes and 2,205ipm (56m/minute) in the Z-axis.

The MX Hybrid Roller Guide System delivers levels of durability and reliability that result in long-term accuracy. By using a greener grease-based lubrication system, the way system increases vibration dampening, extends tool life, handles higher load capacities, and eliminates tramp oil in the coolant.

The Variaxis i-700 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.
