Revolutionary Milling Technology for Wind Tower Structures

Pemamek has launched a groundbreaking line of milling solutions tailored to meet the distinct demands of the wind energy sector and process industry. This comprehensive lineup of milling equipment offers advanced capabilities for longitudinal, circumferential, and edge beveling. Including PEMA LM, PEMA CM, and PEMA EB, the new product family incorporates a pioneering Direct Drive spindle technology developed in collaboration with Germany-based Kessler Group.

The LM milling machine for longitudinal milling enables pre-programmable milling cycles for different thicknesses as well as integrated rollers for workpiece rotation. Capable of milling to depths of 140mm, the PEMA CM for circumferential milling and PEMA LM for longitudinal milling are suitable for preparing narrow gap grooves. The EB edge beveling system offers plate edge milling and preparation, automatic milling cycles, high monitoring precision, and a plate edge scanning function for milling path alignment. All three machines feature the innovative Direct Drive spindle technology, driven by servos and devoid of backlash, offering less vibration and more lifetime for milling inserts. Keeping in line with all PEMA welding and production automation solutions, this technology is equipped with an efficient control system, pre-set parameters, and real-time process feedback as standard features.

Reflecting on the development, Esko Lätti, Product Manager at Pemamek, shared, “Several years ago, the advantages of direct drive machining technology were already demonstrated through initial machining operations using KESSLER’s torque motor technology. I am proud to have been involved in this journey, and I am thrilled to introduce the machinery featuring a torque motor, spindle shaft, bearings, and sensors, all integrated within the same compact and modular spindle unit, developed by the collaboration between Pemamek and Kessler.”
