Nimbus has completed its acquisition of 3M’s Precision Grinding & Finishing (PG&F) business, which now operates as Winterthur Technology Group (formerly part of 3M). The company begins a new, independent phase, focused on innovation, high-performance solutions, and a customer-first approach across industries worldwide.
Renowned for its precision grinding technologies and tailored solutions, Winterthur Technology Group combines deep expertise with advanced manufacturing capabilities. With increased agility and a clear strategic focus, the company is positioned to strengthen its leadership in the bonded abrasives market.
During a transition period, the business will continue to operate under the 3M brand while gradually introducing Winterthur Technology Group as its future identity, ensuring continuity for customers and partners.
