Multi-directional movement design of machining center
Many manufacturers have introduced the "six-sided" and "coordinated motion" machine design concepts, where linear motion machines arranged in multiple directions can achieve the same precision in the XYZ axes as traditional CNC machine tools. These designs aim to enhance flexibility and efficiency in complex machining tasks.
However, despite these innovations, few users actually implement such machines in real-world production settings. Most buyers still opt for conventional machine tool designs when making purchases. That said, at industry exhibitions, potential buyers are often drawn to the intricate movements of these advanced machines, intrigued by their visual appeal and technical complexity.
Yet, an important development has been overlooked in the current landscape of these elaborate "fancy" machine tools. Some machining centers that follow similar principles—known as synthetic motion manufacturing—are starting to gain traction. In synthetic motion machines, different components move in various directions along the X, Y, and Z axes, but their design is based on the functionality of standard machine tools, offering a balance between innovation and practicality.
Here are two notable examples. The first is the "relative motion" machining center from Olympic Seiki (Vigo Machinery in the U.S.). Unlike traditional machines that move either the tool or the worktable separately, this system allows both to move simultaneously. In the X and Z axes, the ball screw moves the table and the tool in opposite directions. The relative feed rate of the tool to the workpiece is the sum of the two movements. Acceleration is also enhanced, with smaller models reaching up to 2g. Additionally, the symmetrical movement of components contributes to better dynamic stability, making the machine more reliable during high-speed operations.
Pivot connectors provide movement in the x direction
Another example is the Genius 500 horizontal machining center from Gross Hüller (now owned by MAG IAS). This machine uses a unique synthetic motion approach: the X-axis movement is achieved through side-to-side motion, while components move vertically along the Y-axis. An inverted V-shaped connector drives the spindle, allowing vertical movement via two linear motors. When both motors move at the same speed, the Y-axis motion is achieved. If they move at different speeds, the center of gravity shifts, resulting in X-axis movement. This eliminates the need for a separate motor for the X-axis, simplifying the design. Furthermore, since the axial motor's force always aligns with gravity, the machine remains well-supported in that direction, preventing lateral forces that could affect accuracy. As a result, the tool can move quickly in both the X and Y axes without compromising stability or precision. This innovative approach not only improves performance but also makes the machine more adaptable to a wide range of applications.Thread Eye Bolts,Round Thread Eye Bolts,Forged Mechanical Lifting Eye Bolt,Fisheye Bolt Eyebolt
