LA-350 & LA-450 Series

LA-350 / LA-450 Series Turning Centers are engineered with a high-rigidity machine body that has been thoroughly optimized through FEM analysis to minimize thermal displacement and maintain long-term machining accuracy. This advanced structural design ensures that the machines deliver consistent precision, even under heavy-duty cutting conditions and extended production cycles.

A 45-degree slant bed design provides optimal cutting geometry, enhancing chip evacuation, operator accessibility, and overall machining performance. To further strengthen durability, the box guide slideways are induction-hardened, ensuring maximum hardness, wear resistance, and structural rigidity for reliable operation over years of use.

The machines are also equipped with large-diameter, high-precision ball screws, which deliver excellent dynamic rigidity and smooth axis movement, allowing for accurate positioning and stable machining even during aggressive material removal. Together, these design elements create a platform that combines rigid construction, thermal stability, and vibration control, making the LA-350 and LA-450 Series ideal for heavy-duty, high-precision turning of large workpieces.

LA-350 and LA-450 Turning Centers are equipped with Taiwan Takisawa’s in-house manufactured spindles, designed to deliver exceptional strength, accuracy, and long-term reliability. Each spindle is built using premium-grade bearings, ensuring smooth rotation, excellent load capacity, and reduced thermal displacement during extended operation. This high-quality bearing system, combined with the spindle’s rigid structural design, provides outstanding resistance to deformation, allowing the machines to handle heavy-duty cutting with precision and consistency.

For models equipped with a gearbox spindle, Takisawa incorporates 0-grade fine-ground precision gears, engineered for maximum accuracy and efficiency. This gearbox design enables the spindle to deliver extremely high torque at low speeds, making it ideal for heavy material removal, large-diameter turning, and difficult-to-cut materials. At the same time, the precision-ground gears ensure smooth transmission and highly accurate surface finishes, even under the toughest machining conditions.

With their combination of rigid spindle construction, premium bearings, and precision gearbox engineering, the spindles of the LA-350 and LA-450 Series provide manufacturers with a powerful, reliable foundation for achieving both high-torque cutting performance and superior machining accuracy.

The LA-350/450 Series is equipped with a high-performance, in-house engineered tailstock designed by Taiwan Takisawa. Built with exceptional rigidity, the tailstock delivers high thrust force and strong clamping capability, ensuring maximum stability when machining long or heavy workpieces. This robust support system helps maintain accuracy, concentricity, and surface quality, even under demanding cutting conditions.

The tailstock body is carried and positioned by the turret, providing a simple and efficient setup process. For added flexibility, the tailstock quill is available in both fixed and rotary versions, allowing manufacturers to choose the configuration best suited for their specific production needs. The quill is hydraulically actuated, providing smooth, reliable operation and consistent holding power.

To further meet the unique demands of different industries, custom tailstock solutions are available, including options for special thrust capacities, quill geometries, and center designs. This adaptability ensures that each machine can be optimized for its intended workload and application.

By combining rigid construction, hydraulic precision, and customizable configurations, the LA-350 and LA-450 Series tailstock system provides the strength, stability, and flexibility required for high-accuracy, heavy-duty turning of large components.
