How to Use Diamond Wheels to Grind Cermet?

图片
Cermet is an important tool material that includes non-metallic refractory composites (ceramics) and metal bond with lower melting point. Diamond wheels grind cermet. They can be economically ground with  diamond wheels , so the range of applications continues to expand. In Europe and the United States, all carbonitride-containing materials are generally considered to be cermets. In Japan, cermets refer only to those materials that contain titanium carbide. As a tool, it must have toughness and wear resistance at high temperatures. Early cermets were very hard but quite fragile, and modern cermets enhanced toughness and reduced hardness. The hardness mainly depends on the titanium nitride and titanium carbide content. The properties of these composites with the binder phase affect their grindability. The temperature of grinding cermet is higher than that of grinding tungsten carbide, and the grinding force is larger, especially the normal grinding force. Diamond whee...

Key Technology of High Speed and Ultra High Speed Grinding for CBN Grinding Wheel

图片
High-speed and ultra-high-speed grinding technology research should be conducted with super-hard material CBN as a tool, modern ultra-high-speed cutting technology and modern high-flexibility and high-automation equipment to accelerate the practical process. The core key technologies for achieving high-speed and ultra-high-speed grinding to be gradually improved include high-speed and ultra-high-speed grinding mechanism research, high-power and high-speed motion unit equipment manufacturing technology, high-flexible and high-automation system, grinding center, research and development about super-hard abrasive micro-powder high-speed grinding wheel preparation technology and super-hard abrasive wheel dressing technology. Vitrified bond CBN grinding wheel is one of the most common wheels. The main research work about high-speed and ultra-high-speed grinding mechanism is to develop high-speed, ultra-high-speed grinding computer animation, vision and predictive simulation software ...

Resin Diamond Wheel can be Used for Grinding Cemented Carbide Inserts

图片
Milling inserts have the highest precision among carbide indexable inserts, and the peripheral grinding machine are used for peripheral grinding of such inserts. Resin diamond wheel can be used for  peripheral grinding . At present, as for the peripheral grinding machines, the grinding wheel frame not only performs high-speed rotation but also axial swing, so that the grinding wheel is generally not trimmed during the whole grinding process to avoid huge waste. However, when the new grinding wheel is mounted on the flange, there is a coaxiality error between the grinding wheel and the flange. Therefore, when new resin diamond wheel is used for the first time, the grinding wheel should be trimmed so that the grinding wheel, the flange and the main shaft could rotate on the same axis. In this way, the wheel could have the correct geometry. Since the grinding wheel is expensive and generally not trimmed, the grinding wheel should be ensured uniform wear throughout the whole use pro...
