Technical Description
The SPINNER MICROTURN L is an ultraprecision horizontal turning center engineered for fine and hard turning applications with linear tool positioning. This machine features a main spindle with a maximum turning diameter of 9.840 inches (250 mm) and turning length of 7.870 inches (approximately 200 mm). The spindle accommodates bar stock up to 1.420 inches in diameter and operates at speeds ranging from 5,200 to 10,000 rpm, delivering high rotational precision. Equipped with high-precision water-cooled motor spindles, the MICROTURN L achieves circularity deviations under 1 micrometer, enabling tolerances between 2 and 3 micrometers for demanding precision work. The machine includes direct measuring systems across all axes with repeatability tolerances below 5 micrometers. The X-axis travel extends 600 mm, Z-axis 350 mm, accommodating complex workpiece geometries. Optional configurations include a secondary spindle for simultaneous machining on primary and counter-spindles, reducing cycle times. The MICROTURN L utilizes the BMT45 tool holder system, providing 12 stations with optional powered positions for versatile turning and milling operations. Integration of a servo turret and Y-axis option transforms the machine into a universal precision turning center capable of both conventional and advanced machining applications. This modular design enables users to scale from basic fine turning to comprehensive turning-milling operations without compromising precision or rigidity.
