ATRUMP LA-20L HORIZONTAL MACHINING CENTER

The ATRUMP LA-20L is a CNC horizontal machining center designed for precision turning operations, featuring a robust 15 HP spindle motor capable of up to 4,500 RPM. It supports a maximum turning diameter and swing of 15.750 inches, with a maximum spindle chuck diameter of 8 inches and accommodates bar diameters up to 1.650 inches. The machine operates on 2 axes (X and Z), with an X-axis travel of 5.310 inches and Z-axis travel of 24.410 inches, both with a rapid traverse rate and max feed rate of 590 inches per minute, enabling efficient and precise machining cycles. The primary tool carrier is an 8-position turret supporting a single simultaneous cutting tool, optimized for turning processes. The machine has a spindle bore diameter of 2.05 inches (optional), spindle nose A2-6, and includes features such as automatic lubrication, telescopic slide way covers, and a fully enclosed splashguard. Control is typically handled by a FANUC OTC or Centroid M400 CNC system, allowing for 2-axis simultaneous movement, part program storage, scaling, G-code compatibility, and various operational safety and control functions. The LA-20L has a maximum turning length of approximately 23.62 inches and a distance between centers of 24.41 inches. The machine weighs about 7,717 pounds and measures roughly 92.5" L x 74.8" W x 70.9" H. It is well-suited for bar, chucker, and universal turning applications with precise positioning repeatability down to ±0.0001 inches.
