Since itsfoundation Saint - Gobain has concentrated oninnovation and expertise in the area of technicalmaterials. In many industries Saint - Gobain has becomea market leader. Today Saint - Gobain employsapproximately 16,000 people in the area of bondedabrasive products and dressing tools.Saint - Gobain is present in 45 countries worldwide andis the largest manufacturer of dressing tools andabrasives in the world.Advanced technologiesManufacturing technologySaint -Gobain has developed up-to-date productionfacilities, through continuous investment inmanufacturing equipment. Its excellent on-time deliveryperformance is backed by in-depth product knowledgeand very high quality levels.Saint - Gobain Diamantwerkzeuge is certified accordingto ISO 9001; ISO 14001 and has also obtained theprestigious FORD Q1-Certification.Technology Center for Abrasives EngineeringThe objectives of the technical centers are to developand improve grinding technology.These are located in Germany (at Norderstedt, nearHamburg) and in the USA (at Worcester, near Boston).They support customers in developing their demandsfor the future, allowing them to become world class intheir application of dressing tools and abrasives.These „“Centers of competence“ include developmentslike „System concept“ that describe the microscopicinterrelation of the process during the dressing andgrinding process. To gather and spread this knowledgeof dressing and grinding, there is an European TechnicalData Base (ETDB) created at the local level.Absolute Dressing precision with WINTERHigh accuracy dressing tools are needed to dressan abrasive wheel to close tolerances. Only then it is itpossible to guarantee the quality of the componentsproduced.Saint - Gobain produce the following diamond dressingtools with the WINTER brand:- CNC rotary roller dresser- CNC stationary dressing tools- Rotary profile roller dresser- Rotary single taper dressing disc and profile rollerdresser2

PCBN hard machining insertsSaint-Gobain Abrasives manufacture a range of hard machining inserts using selectedPCBN grades.The PCBN tool material is sintered at high pressure and temperature and then processedusing spark erosion and grinding methods to form the finished tools.PCBN tools can give better surface finishe along with improved tolerances, less down time,lower cutting forces and lower cost per part when compared to conventional grinding.PCBN inserts are suited for the machining of hard ferrous materials with and withoutcoolant. Suitable work piece materials include hardened steels (>45HRC), sintered irons,grey cast iron, chilled cast irons and hard facing alloys.The inserts are available in standard ISO formats as well as bespoke tooling.The advantages of using PCBN tools are as follows:- Reduced machining costs- Improved work piece quality- Ideal solution for roughing and finishingoperations- Process reliability improvement- Reduction in environmental issues- Machining possible without coolantGroove machining: Bespoke tooling solutions PCBN grades for continuous and interrupted cuts Tool widths 1,5 mm - 5 mm are possible Width tolerances of 0,01 mm are possible Tool life potential > 500 partsOuter diameter machining: Standard ISO formats are available PCBN grades for continuous and interrupted cuts Possible surface quality of R a0,2 Tolerances of 0,005 mm are possible Suitable for a wide variety of applicationsBore diameter machining: Standard ISO formats are available PCBN grades for continuous and interrupted cuts Surface quality by R a0,2 Tolerances of 0,005 mm are possible Suitable for a wide variety of applications24
