Compact Lehmann rotary tables show their advantages by being light in weight and small in footprint, but strong when it comes to clamping torque and load weight. These attributes means users still have space on their machine tables for three-axis operations as room remains for additional vices.
The company’s modular system is based on four sizes of rotary table, which are expanded by a building kit to create customer solutions. With a clamping torque range of 250 to 5000 Nm, spindle load capacity between 17 and 1600 kg, speed of 40 to 300 rpm, and accuracy of 2 arc-sec, the company says its rotary tables are in a class of their own.
Lehmann’s range also allows the creation of different fourth-axis solutions with up to four spindles, tailstocks and counter bearings, as well as a five-axis solution. In addition, the modular systems allow a direct encoder and special labyrinth seal for grinding applications.
