The Tongtai CT-350 is a compact Vertical 5-Axis Machining Center designed for multi-face machining of precision components and small molds. It is an ideal solution for manufacturers in the automotive, medical, precision engineering, and mold & die industries looking to adopt advanced 5-axis machining while maintaining a cost-effective investment.
Built with a high-rigidity machine structure, the CT-350 is equipped with a roller cam-driven A/C-axis rotary table that provides high torque, zero-backlash positioning, and outstanding machining stability. This configuration enables precise simultaneous 5-axis machining, allowing complex geometries and multi-angle features to be completed in a single setup, reducing setup time, minimizing cumulative errors, and improving overall productivity.
The machine offers 400 mm X-axis travel, 510 mm Y-axis travel, and 510 mm Z-axis travel, providing an optimized work envelope for high-precision applications. Its standard 15,000 rpm spindle, with an optional 20,000 rpm high-speed spindle, delivers the flexibility required for both efficient roughing and high-quality finishing of intricate parts.
The three-axis linear guideways adopt a wide-span design, enhancing structural rigidity and torsional resistance from the foundation.
Combined with roller-type linear guideways and double-nut preloaded ballscrew technology, the machine effectively suppresses thermal deformation during operation, ensuring excellent geometric accuracy even under long-duration heavy-duty cutting conditions.
The A/C axes utilize a roller cam drive mechanism, leveraging rolling contact characteristics to achieve low starting torque and fast rotational response. Compared with conventional worm and worm gear systems, this design provides zero backlash and extended service life. Even under long-term operation, it requires no adjustment, ensuring consistently high rotary positioning accuracy
The spindle is equipped with oil-air lubrication and an oil-cooled spindle sleeve to effectively dissipate heat generated at high speeds, significantly reducing the impact of thermal expansion on machining accuracy.
Standard BBT dual-contact tool holders enhance clamping rigidity and reduce vibration, ensuring excellent machining stability and superior surface finish even during high-speed operation.
The tool magazine offers flexible configurations ranging from 24 to 40 tools to meet the demands of complex machining operations.
Combined with a cam-driven high-speed automatic tool changer, it provides reliable and efficient support for high-productivity production lines.
