Precision balancing of rotors As the operator of the largest independent high speed dynam- ic balancing machine in sub-Saharan Africa, Marthinusen & Coutts , a division of ACTOM , has an in-depth understanding of the importance of precision-balancing rotating machines. Mike Chamberlain, marketing and commercial executive, points out how critical it is to ensure the highest degree of accuracy when balancing rotating machines as this will mini- mise vibration levels thereby increasing reliability and reduc- ing maintenance costs. The 32 ton Schenck HM7 U/S balancing machine is in constant use. “Our customers, which include major local and international OEMs, benefit significantly through access to an independent balancing service offering with this level of capacity and quality.” The HM7 U/S balancing machine has a measuring range between 100 and 5 000 r.p.m. It is nine metres long, has a journal size of 400 mm and a swing of 2,4 metres. The ma- chine is fitted with a CAB 920 H computer measuring system with advanced functionality. “This state-of-the-art technology makes changeovers to new rotor types quick and straightforward, and the machine is capable of balancing larger high-speed rotors dynamically at full operating speed,” Chamberlain says.
