Sandvik Coromant Trondheim
UNMANNED PRODUCTION & DOUBLE CAPACITY
Sandvik Coromant entered into a partnership with Teenees from Trondheim in 1970 to produce so-called Silent Tools. Equipped with a damping system, the unique range of tools and adapters minimizes vibration, even with a long tool overhang. Sandvik Coromant took over the partner in 2008 and has continuously developed this product division. With 105 specialists and modern machine tools, the tool manufacturer ensures that customers from all over the world and all industries receive first-class solutions, from standard products to special developments. Since 2001, Sandvik Coromant Trondheim has often relied on automated CNC technology from DMG MORI. After the initial use of gantry solutions, DMG MORI installed an NZX 1500 with robot handling for the first time in 2020. This was followed in 2023 by an automated NTX 3000. The manufacturing solution enables highly flexible production of a wide variety of CAPTO tool bodies.
The automated NTX 3000 enables us to manufacture tool bodies to high precision to within tens of microns thanks to the integration of turning, milling and in-process measuring on one machine.

PRECISION TOOLS WITH INTEGRATED DAMPING SYSTEM
“We manufacture 450 standard products in Trondheim and ten percent of our business is customer-specific tool solutions,” says Steinar Løkken, Manager Technical Operations at Sandvik Coromant Trondheim, about the scope of production. Silent tools are a core business. Inside these turning, milling and drilling tools is a preset damping system consisting of a heavy damping body supported by two springs. When vibration occurs, the kinetic energy is absorbed by the damping system. This minimizes the vibration, improves surface quality and increases productivity.
