2 2 3 oo ver the last 50 years Diager Industrie has established itself as the specialist in carbide tools. With modern machinery and a strong research and development department to rely on, Diager Industrie is able to take advantage of all synergies of a group to design high quality tools for industrial customers. Working in genuine partnerships with major clients in the automotive, engineering or aerospace industries, Diager Industrie puts the best of its expertise into its range of quality products. DIAGER INDUSTRIE To benefit from the latest technical developments. Tool ranges : DRILLING REAMING MILLING Carbide Brazed carbide PCD CBN Steel Services : Technical assistance on customers production sites. Validation of tools at DIAGER Industrie. Tool maintenance (grinding and coatings). Tool management contracts. Logistics : Orders managed with the A.L.F. system (supplier delivery assurance). -Orders handled by E.D.I. (electronic data interchange). GENCOD labelling. A close and lasting partnership : DIAGER INDUSTRIE s development depends on the more and more sustained presence of its teams accompanying its customers in the development of their new parts through to series production, with a constant concern to improve productivity.

3 RESEARCH & DEVELOPMENT Research and development occupy a central role at DIAGER INDUSTRIE. They are what enables the company to progress and improve the performances of its products and to integrate new technologies as soon as they become available. Thanks to its long-term vision and permanent efforts, DIAGER INDUSTRIE s R&D enables it to stay ahead of its competitors with significantly superior technologies. Workpiece inspection : Coordinate measuring to determine tool capabilities : Dispersion of the dimensions between different reaming operations, bore ovality, flatness, surface perpendicularity of surfaces, process capability (CAM-Cpk). Roughness meter : to check surface finish. 2 point bore gauge : to check bores. 3 point micrometer : to check bores. Special fixture for checking burrs. Tool inspection : Digital cameras with optical zoom from 10x 320x : to check wear and edge sharpness. Laser dimensional measuring. Presetting device. Carbide geometries MQL Dry Coatings Test equipment : Test platform consisting of : 24,000 rpm machining centre with 50 bar central lubrication or central microlubrication, HSK 63-A spindle, Siemens 840D CNC control system. Kistler table for tool/material pairing. Portable equipment. 4 5
