5 machine shape
Today's gear grinding machines are smaller in size and occupy less floor space, which allows manufacturers to better use limited production areas to “create†more available space without having to spend money on building bricks and cement. "On, and used to purchase equipment.
6 new material grinding wheel
Advanced ceramic bond grinding wheels and electroplated cubic boron nitride (CBN) wheels have the same high productivity. Due to the use of new materials in the "mixed particle" type composition and the advancement of the bonding process, the toughness, shape accuracy retention, material removal force and durability of the ceramic bond grinding wheel are improved. These excellent properties are derived from high performance particle structure and increased porosity. At the same time, a good particle structure reduces the grinding pressure and reduces the grinding temperature.
Nowadays, the selection of electroplated CBN grinding wheels and ceramic bond grinding wheels has become difficult due to the use of new cold-grinding ceramic abrasive grains of high-pressure coolant systems. However, the electroplated CBN grinding wheel is simpler to operate than the ceramic bond grinding wheel, has a short installation time and requires less technical ability of the operator, and provides a more feasible low-cost option for the CBN abrasive grain ceramic bond grinding wheel.
Reishauer of the United States tested these ceramic wheels with their "cold grinding" process and concluded that: 1 The latest alumina abrasives and ceramic abrasive wheels produce the same or lesser pressure than CBN abrasive ceramic bond wheels. 2 Contrary to expectations, ceramic wheels are more efficient and durable than CBN wheels. 3 Unlike the electroplated CBN grinding wheel, the ceramic grinding wheel can be rebuilt sharply on the grinding machine, and the electroplated CBN grinding wheel must be sent back to the original factory for grinding.
Ceramic grinding wheels have a high cutting speed (eg 60m / s), so it is suitable for large-scale production of gears. This type of grinding wheel has a longer service life than other grinding wheels (such as alumina grinding wheels). The new grinding wheel technology is used more in the worm grinding wheel of the 200mm and below gears with the largest output.
7 Reduced grinding costs
Nowadays, the cost of grinding teeth has dropped drastically. There are many reasons, such as cost-effective models based on modular design, CNC systems, process production, etc. Even the gear grinding machines that combine all the above advanced technologies are cheaper than the previous models. Much, high-volume production has reduced the single-piece production cycle by 50% to 70%, and the cost of consumables (grinding wheels and diamond modifiers) has also dropped significantly.
