Physik Instrumente (PI) Acquires P·G·W, Japanese Granite Base Machining Company

Karlsruhe, Germany – Physik Instrumente’s 100% acquisition of P·G·W Precision Granite W Co. Ltd was completed on February 25, 2021 and is a major step forward in the company’s expansion plan of a PI Design Center in Asia. This builds upon last years’ growth when PI opened a production plant in Changzhou, China.
Future Business Success
Granite has a unique thermal and vibration-damping properties and is employed in many of PI’s multi-axis air bearing and gantry systems. P·G·W’s highly accurate competencies with machined granite base plates fit perfectly with PI’s corporate strategy of establishing a global network of PI Design Centers. Assembly of complete precision motion control systems at P·G·W is also planned for the future.
The addition of PGW completes the system approach for PI’s portfolio and strengthens the commitment to the growth markets in Asia. PI and PGW have maintained business relations for many years and the transfer of the company was part of Hayata Watanabe’s succession plan.
Granite based motion systems and integrated granite motion systems provide significant precision advantages in applications such as semiconductor manufacturing, laser machining and optical metrology.
