STL12

The Z-MaT STL Series high-performance turning centers were designed from to provide setup flexibility, superb rigidity, and excellent thermal stability. These machines offer high cost performance. STL lathe have a heavy-duty cast base with “true align” slant bed design. The machine bed, headstock, turret and tailstock are aligned on the same plane. This unique design feature reduces heat built-up and resulting thermal expansion. The net result is higher precision machine tool. Additional resulting efficiencies from the “true align” design are greater rigidity and smoother operation which provides a variety of benefits. You can expect to produce highly accurate parts with extremely fine surface finishes. There are multiple benefits to having a lathe that combines such a large sized “vibration damping” solid, cast base PLUS, properly aligned and balanced components. Some of these benefits include: Smoother slide surface operation Higher speed and accuracy Fewer machine adjustments and lower maintenance costs Shortened machine warm-up time Lower power consumption

• True slant bed minimizes the impact of thermal expansion to precision. 35 degree bed slant is more convenient for scrap iron
• Better dynamics and higher precision
• It realizes an optimized combination of high-precision, high bearing capacity, good running speed and it is more durable
• Increasing the versatility and automation of the lathe
• Better water-resistant and scrap-iron-resistant
