Zhuzhou tongda has in tungsten carbide turning tool possession an advanced production line for manufacturing dies and moulds and a production line for post machined cemented carbide products. We can also supply tailor-made products of various specifications based on the requirements of our customers. Because of tungsten carbide turning tool high precision and high reliability, tungsten carbide inserts have been broadly used worldwide for significant productivity improvements. Tungsten carbide has extremely high hardness and wear-resistivity compared with conventional steel materials, and it is expected that the tungsten carbide can be applied widely to dies and molds in the near future. In order to develop an efficient machining method of tungsten carbide for the dies and molds, series of cutting experiments were carried out to turn the sintered tungsten carbide materials with CBN tool. The selected sintered tungsten carbide work pieces are those containing tungsten carbide grains with mean grain size of 5m, and 15wt%, 20wt% and 22wt% of cobalt binder. The sintered CBN tool selected contains super-fine grains of CBN with mean grain size of 1m. The cutting speed was varied from 10mmin to 60mmin, and the tool wear and the surface roughness were measured. It is concluded that the tool wears less when cutting the sintered tungsten carbide containing larger amount of cobalt binder. The surface roughness of about 2m in Rz is obtained.
