NEWS RELEASE: March 17, 2020: Macfab Manufacturing, an international supplier of precision components and sub-assemblies, today announced that the company has committed to a significant investment in a hard-bearing measurement system with two-plane dynamic balancing capability.
This technology is used for high-precision balancing of rotors of widely varying sizes – ranging, for example, from dental drill rotors to the much larger rotors used in electric motors, turbines and generators in a variety of industries. Macfab’s initial focus will be on balancing rotors used in reaction wheels for satellites. The new system is calibrated and certified in accordance with SAE ARP 4048. As a result, Macfab will be able to deliver components conforming to the optimal grade, designated as G 0.4 from ISO 1940/1.
Another turnkey solution for satellite component customers
The purchase of precision-balancing equipment is the latest in the company's long history of technology investments that further the company's ability to deliver turnkey solutions. In the case of satellite component manufacturers, including precision-balancing as part of Macfab's full suite of services provides several important benefits. "A big factor is streamlining the supply chain," says Macfab president Chris Macmorine.
“Previously, our clients would purchase the machined component from us, cleaned to a very high standard. They would then do the assembly at their facility, then send it out to a precision balancer and wait another six to eight weeks. Now that client can come directly to us. We’ll machine the part from raw material, we can assemble it with all the other components, clean it, balance it, and then do a final cleaning, and send it to them – certified and ready for installation. The result is reduced lead times, lower overall cost of the assembly and, again, a much more simplified supply chain.”
