High speed grinding pursuit of modern manufacturing technology to achieve two major goals to improve product quality and labor efficiency. Practice has proved that: the grinding speed increased to 50 ~ 60m / s, 35m / s, generally in the production efficiency can be increased by 30% to 60%, an increase of about 0.7 to 1 times of wheel durability, the workpiece surface roughness parameter value reduces about 50%.
    General grinding speeds up to 45m / s or more known as a high-speed grinding. Domestic I developed in the eighties ZYS-811 automatic bearing internal grinder ferrule grinding application of high-speed grinding technology, the first domestic bearing industry, supporting the successful development of a high-rigidity, high-speed, high-power electric spindle and High-speed wheel. While the high-speed grinding at home and abroad has long been widely used, and with the widespread adoption of high grinding ratio, high durability super abrasive such as CBN, grinding wheel speed has reached 80 to 120m / s, or even higher. : Germany Mikrosa, Japan KOYO centerless grinder, Japan TOYO bearing inner grinder, the outer surface of the grinding wheel speed up to 120m / s, the inner surface of the grinding line speeds up to 60m / s to 80m / s.
    Increases the grinding wheel drive (transmission) system power increased rigidity, an important measure to achieve high-speed grinding, and the most critical parts of its high-speed spindle unit high-speed grinder. High speed grinding wheel should have sufficient strength, but also the need to ensure a good grinding performance, in order to obtain high grinding effect. In addition, the cooling device is also one of the indispensable means to achieve high speed grinding.
The outer surface of the grinding wheel automatic dynamic balancing technology
    The outer surface of the grinding, the grinding wheel is large and non-homogeneous organization, wheel system center of gravity of the total deviation from the spindle heart, would inevitably lead to the high-speed rotating grinding wheel system and its whole machine vibration, directly affect machine life. In this case, the grinding process will be difficult to achieve high precision, easily lead to the workpiece surface grinding chatter, waviness increases.
    Machine tool mechanical or other means automatic dynamic balancing device on the wheel is installed directly on the boot quickly and directly approaching the most balanced position, improve self-balancing can also omit the grinding wheel static balance. The breakthrough of the technology to promote the development of grinding technology, while extended wheel trimmed with diamond and spindle bearing life, reduce machine vibration, and long-term to keep the machine accuracy of the original.
Rapid elimination of the inner surface of the grinding empty process technology
    Grinding equipment of all bearings, the inner surface grinder level symbolic significance. This the main grinding aperture limit wheel size and the corresponding system institutions collection parameters, rigid restrictions on the fundamental process system, while its high machining accuracy. These internal surface grinding process requires us to enter the in-depth study, in addition to limited play machine grinding wheel cutting ability, reducing the auxiliary grinding the time improve grinding efficiency is the key, because the grinding air-way total grinding time about 10%.
