American Machine Tools and German Quality Standards
UNISIG was founded in 1981 for the production of deep hole drilling equipment, as well as sales and service of VDF machine tools. In 1995, UNISIG was acquired by Entrust Manufacturing Technologies, Inc. and relocated to its current headquarters in Menomonee Falls, Wisconsin, USA. Continuous investment in the development of deep hole drilling machine technology, experienced employees, as well as a state-of-the-art manufacturing facility has fostered growth and development of the deep hole drilling industry, as well as provided drilling equipment to industry leading corporations worldwide.
The committment to the metric system as well as DIN, ISO and IEC standards are the basis for design and manufacturing. The use of proven components as standard elements from FAG, Heidenhain, INA, Parker, Rexroth, Rohm, Schunk, Siemens, SKF, Wittenstein alpha and ZF lead to a highly reliable product - ideal for users in the European metal processing industry.
With the establishment of UNISIG GmbH in Germany in 2011, UNISIG reinforced its commitment to the European market. UNISIG in Europe offers the entire system for deep drilling, from the machine itself, to durable tooling and machine accessories, automation, and training. The program offers UNISIG precision machines for almost all applications, even for tough, high-strength materials. UNISIG application engineers assist you in selecting the appropriate machines, tools and procedures - even after the sale.
