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 ...

Advantages of New Type Vitrified Bond CBN Grinding Wheel

图片
CBN is a new type of superhard material with ultra-high pressure and high temperature technology after synthetic diamond using . CBN and its products are mainly suitable for precision grinding of tool steel, alloy steel, heat-resistant steel, stainless steel and other materials. Although the cost is slightly higher than that of general abrasive grinding wheel products, thermal stability and chemical inertness are superior to general abrasive wheels, diamond wheels, etc. Vitrified bond CBN grinding wheels are common used wheels during grinding process. Grinding performance of grinding wheels is different with diamond, CBN, silicon carbide and corundum abrasive. Diamond is the hardest abrasive, but it’s not ideal used for steel material with large grinding toughness due to poor thermal stability. Silicon carbide wears rapidly due to its low hardness and chemical activity to iron group metals. Corundum is a conventional abrasive used for grinding steel material, but the hardness is rel...

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...
