CGW’s R&D works in collaboration on all research activities with an academic advisory board: Prof. Gideon Grader, Dr. Ori Ramon Ceramic testing laboratory of Prof. Gideon Grader;
research projects with the Israel Ministry of Science:
-
Development of next generation highly interconnected porous, form holding, cool grinding wheels with high dimension stability
-
Research of grain-bond interface and its effect on grinding performance
-
Development of next generation ceramic bond, in cooperation with CGW’s bond supplier
-
Cooperation with leading grinding technologists Prof. S. Malkin & Dr. Jeffrey Badger
-
Development of the CGW-GKS with Dr. Jeffrey Badger Dressing technology in collaboration with Urma-Rolls Cooling technology solutions with Dr. John Webster
R&D - Quality department activities;
-
Raw materials specifications and quality control;
- On-line quality control – green strength, green Rg, kiln temperature uniformity, E-module, final Rg;
- End product quality testing machines;
Process uniformity;
-
Mixture parameters – humidity control, green strength and Rg;
- Kiln temperature and oxygen levels uniformity during sintering;
- Automated and calibrated mixture preparation, wheel press and non destructive testing during production minimizes depreciation and maximize uniformity and reproducibility;
100% quality testing to wheels for aviation technology:
-
Green strength & hardness;
- Rg [including sigma for uniformity];
- E-module [including sigma for uniformity];
- Wheel hardness radial & up to down uniformity;
- Wheel balance testing;
- Wheel speed test testing;
- Visual testing;
