KTGL-Series Inverted Vertical CNC Lathe
Product Highlights
The KTGL-Series offers cutting-edge technology designed for precision, stability, and efficiency in automated production. It features a thermo-symmetric spindle headstock that reduces thermal displacement, ensuring consistent accuracy during extended operation by minimizing radial distortion. The high-efficiency, low-heat spindle motor with advanced control technology enhances performance and durability.
Designed for automated production, the machine uses a reverse lathe design with an automatic feeding mechanism. The lathe chuck handles loading and unloading workpieces, boosting productivity and reducing manual intervention. The soft jaws easy forming function allows for quick shaping and faster turning completion.
The loaderless system increases efficiency by using a vertical spindle head that moves horizontally (X-axis) and vertically (Z-axis). Acting like a loader, the downward-facing chuck loads and unloads workpieces with ease, accommodating parts up to Ø3.94″ in diameter (Ø100 mm).
Built for scalable automation, the machine is compatible with various automatic feed-in systems, making it a flexible and reliable solution for high-volume production with minimal manual handling.
