In a 3-axis machining center composed of three slide axes (X-axis, Y-axis, and Z-axis), the machine's structure limits the approach direction for machining to only the top surface of the workpiece. Therefore, when performing complex and high-precision machining that requires angle determination, it is necessary to first create a fixture to tilt the workpiece and repeatedly grasp and reposition the workpiece. As the work becomes more complex, the 3-axis machining center has disadvantages compared to the 5-axis machining center, such as unstable angle determination accuracy, the need for setup changes, and the requirement for indexing fixtures. In contrast, a 5-axis machining center, which consists of five axes (X-axis, Y-axis, Z-axis, + A-axis (rotational axis relative to the X-axis) or B-axis (rotational axis relative to the Y-axis), + C-axis (rotational axis relative to the Z-axis)), allows for approaches from arbitrary angles to complex workpieces with a lot of angle information. We also accept 5-axis three-dimensional shape machining. When machining vertical wall shapes where the cutting tool cannot reach from the top surface, we can use short-reach cutting tools, enabling us to achieve high surface finish accuracy.

Our company's NC lathe-type multi-tasking machine is designed to perform high-precision angular indexing drilling and milling operations without removing the workpiece, all while simultaneously carrying out turning operations with a single chucking. This allows for the processing of complex workpieces in a short amount of time. Furthermore, multiple workpieces can be processed unattended with a single program, which significantly contributes to cost reduction as the quantity increases. If you are facing challenges with high-precision angular indexing in turning operations, please feel free to consult Tsukii Precision.

Universal milling machines can quickly and cost-effectively process parts that are difficult to machine with NC machine tools, as well as simple workpieces. We aim to utilize the advantages of numerical control machine tools and general-purpose machines according to the specific processing requirements.
