Tiges de carbure de tungstène pour fraises et perceuses en bout de haute qualité stable
1.Les tiges de carbure de tungstène solide sont moulées à la presse par moulage ou extrusion.
2.Les tiges de carbure de tungstène sont frittées par un four intégré de frittage à basse pression, les performances globales sont donc élevées.
3.La barre ronde en carbure de tungstène-cobalt brut, ou le diamètre extérieur de la barre ronde peut être affiné et poli selon n'importe quelle tolérance. Les tolérances courantes sont h5, h6, -0,005, etc., et le chanfrein d'extrémité des tiges en carbure peut également être traité.
4. Les tiges de carbure conviennent au traitement de l'acier général, de la fonte, de l'acier inoxydable, de l'acier résistant à la chaleur, de la base de nickel et de l'alliage de titane. Recommandé pour les matériaux d'outils en carbure à usage général tels que les forets hélicoïdaux, les fraises en bout, les tarauds et les forets à pistolet.

more than 50 years production and management experience，Advanced production technology, High-precision machines, Strict QC management system, Special-designed packing boxes and tubes, Various shipping methods
1.Tungsten carbide blanks production
Good quality carbide products rely on 100% virgin raw materials and advanced wet-milling,pressing machines and sintering furnaces. We put emphasize on every production process of our carbide blanks. To keep good quality of carbide blanks is the base of furtherly machined high precision finished carbide parts.
2.Inspection and testing process
In order to ensure the quality of all our tungsten carbide finished products, a very strict QC management system we called “Quality Control Center” has been introduced. With our advanced inspection equipment and our professional inspectors, we are able to do raw materials inspection, on-site inspection and after finishing inspection to ensure 100% good quality of your carbide products.
3.Advanced CNC Equipment
NCC owns a series of high-precision grind machines, including flat grinding machines, OD and ID machines, Centerless grinding machines and customized grinders. Also we have CNC machines, EDM, Wire-cutting machines and drilling machines etc. With our skilled workers, we can control very high precision of each carbide part.
4.Packaging and Shipping
Special-designed packing boxes and tubes will be used properly for the standard and customized carbide products to ensure the safety of the goods during the transportation process.A wide range of shipping ways can be available for your shipments, for example we can ship goods by Sea, by air and by Express companies like DHL/FedEx/UPS/TNT etc.
