MAKRA BUP Alloy Wheel Fatigue Strength Test Machine

April 01, 2014

LMC Workholding is now offering Alpine Metal Tech GmbH products in North America for the alloy wheel manufacturing industry. Alpine Metal Tech, part of Montana Tech Components AG, offers products worldwide under the leading brand names of Numtec and MAKRA. Numtec supplies machines and devices for the production of aluminum passenger car wheels with a primary focus on the handling, coding, identifying and measuring of the wheel at various stages of the manufacturing process. MAKRA machines provide aluminum wheel testing and enable aluminum wheel producers, inspection authorities, and automobile manufacturers to ensure that all standards, regulations, and safety requirements are fulfilled.

One such machine is the MAKRA BUP Alloy Wheel Fatigue Strength Test Machine. Through the application of a centrifugal force applied by a rotating counterweight, the BUP test machine duplicates those forces that are applied to the front wheel of an automobile during hard right or left hand turns at high speed.

"We're delighted to be able to work with Alpine Metal Tech. Our LMC wheel chucks keep us very close to the wheel industry and these new products are a great addition," said Jay Duerr, President of LMC Workholding.
