pL Lehmann Rotary Tables
EXSYS Tool Inc., well known for its high-quality, productivity-boosting solutions for CNC turning centers, now offers those same benefits for customer milling applications through a new line of LEHMANN high-precision rotary tables.
The Swiss-manufactured LEHMANN 500 series of modular multi-axis rotary tablesallow users to upgrade a vertical machining center to significantly increase productivity without incurring the expense of a new machine.Adaptable to nearly any workpiece or production situation, the tables are available in four basic models that can be assembled into as many as 240 different configurations. More than 20 different clamping methods and behind-the-spindle accessories that include rotary unions, special clamping cylinders and angular position measuring systems further extend the system’s adaptability.
Compact LEHMANN tables consume a minimum of space in the machine work envelope, facilitating optimal tool access to the workpiece. Despite their space-efficient dimensions, the tables and spindles offer strong resistance to pull-out torque and axial force while providing high levels of clamping torque. Engineered for low power consumption and light weight, the tables feature IP67 rated enclosures.
Both single-spindle and multi-spindle tables are available in 4-axis and 4/5-axis versions. Swiveling-bridge-style 4-axis tables employ the roto-FIX clamping yoke for machining of multiple parts. The tables’ backlash-free preloaded gear drives (PGD) provide both high torque and high rotation speeds, with spindles capable of 47-111 rpm and cycle times for 90 degrees of 0.34 sec. LEHMANN 5-axis tables operate in simultaneous machining or productivity-enhancing 3+2 positioning modes.
