Mazak Spotlights High Accuracy of VARIAXIS i-800 at DISCOVER 2013

Highly versatile machine processes large, heavy workpieces in single setups

FLORENCE, Ky., Oct. 8, 2013 – At DISCOVER 2013, Mazak demonstrated how its precision-focused VARIAXIS i-800 vertical machining center with a table size of Ø31.5” x 24.8” is ideal for the aerospace industry. The highly versatile machine uses its simultaneous 5-axis capabilities to perform multiple and complex curved surface machining on large, heavy workpieces in single setups.

Able to handle all processes from raw material input through final processing on a single machine, the VARIAXIS i-800 provides dramatic reductions in lead-times and improves workpiece accuracy through the elimination of multiple setups.

With a Y-axis travel of 33.46” (850 mm) and X-axis of 28.74” (730 mm), the VARIAXIS i-800 easily accommodates workpieces measuring up to 39.37” (1,000 mm) in diameter and 19.69” (500 mm) high. Its roller gear cam-driven rotary/tilt table, with 360 degrees of rotation in the C-axis and +30 degrees through -120 degrees 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 10,000-rpm, 40-hp, 50-taper spindle with a compact nose design that helps increase the machine’s Z-axis stroke to 22.05” (560 mm) and overall machining stability by allowing for the use of shorter tools. An optional 18,000-rpm 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 1,654 ipm (42m/min) 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. The 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.

The VARIAXIS i-800 easily pairs with an optional two-pallet changer to achieve continuous machine operation that results in reduced part cycle times. It is also compatible with Mazak’s PALLETECH Manufacturing System, which drastically improves machine utilization and allows for unattended lights-out operation.
