The ST Series from ShangJie PM offers slant-bed CNC lathes equipped with linear turret systems for enhanced rigidity and cutting precision. Designed for medium-to-high volume production, these machines deliver excellent chip evacuation and stable machining at high speeds. Ideal for processing shafts, bushings, and threaded components, the ST Series suits industries such as automotive parts, industrial tools, and hardware manufacturing. Its inclined bed design improves operator access and reduces thermal distortion, ensuring long-term machining accuracy.
Slant-bed structure for efficient chip flow and stable operation
Linear turret enables fast tool indexing and smooth finishing
| ● Casting Material Machine bed is constructed with HT300 grade cast iron as a monolithic casting, processed through vibration aging and double tempering treatments to eliminate residual stresses. This ensures exceptional dimensional stability and long-term durability, guaranteeing consistent machining accuracy during extended operation.
The machine tool's structural design features a monoblock bed with a low center of gravity. Finite Element Analysis (FEM) is employed to optimize the geometry and layout of reinforcing ribs in the cast components, maximizing bed rigidity. This configuration ensures superior performance in heavy-duty cutting operations while extending tool service life. |
