It's called "The Pinnacle of Mass-Production". Up to 3 turrets can be installed, all of them Built-in Motor Turret (BMT™). By placing the motor inside the turret, heat generation and vibration are reduced to a minimum and transmission efficiency is improved. Cutting performance, speed and precision are also increased. The previous model worked with a transmission structure with many heat-generating parts such as gears and belts, which affect machining accuracy, but the new nz series tourret works with a built-in motor, there is no transmission structure. The sources of heat are reduced, and the motor is also surrounded by a cooling jacket.
The new NZ Series of cnc multi-axis machines offers not only turning, but also excellent milling with the Y-axis. With the longest Y-axis stroke in its class, it achieves high-precision, high-efficiency machining.
Mori Seiki's original technology, the Octagonal Ram Construction (ORC™), is a fundamental improvement on the weaknesses of conventional moving structures. With the symmetry of an octagonal shape, thermal displacement is controlled and stable straightness is ensured even at high speeds. It offers stable, high-precision machining.
The cnc's engeniers had achieved both high flexural rigidity and a light body by making repeated use of the most advanced analytical techniques. They've used Finite Element Method (FEM) analysis to simulate the structure's deformation under load. By making fine adjustments to every detail, from the thickness of the bed to the shape and arrangement of the ribs, they achieved high fl exural rigidity. At the same time, we managed to make the body light.
