CSJ Series

Developed by ACE Designers, the CSJ-400XL is a high-performance horizontal boxway lathe engineered to deliver strength, precision, and efficiency within the smallest footprint of its class. Despite its compact size, the machine incorporates advanced structural features, including a step-up Z-axis design and an FEA-optimized bed that enhance rigidity, stability, and vibration damping during demanding cutting operations. Its best-in-class swing diameter further expands machining capacity, allowing the CSJ-400XL to handle larger and more complex workpieces without compromising accuracy.

At the core of the CSJ-400XL is a thermally stabilized spindle system designed for consistent performance in high-production environments. Capable of reaching speeds up to 4,000 rpm and powered by a robust 20/15 HP AC spindle motor, the machine delivers both the speed for fine finishing and the torque for heavy-duty cutting. This combination of rigid construction, compact design, and powerful spindle performance makes the CSJ Series an ideal choice for manufacturers who require maximum productivity and machining versatility in a space-efficient platform.
