ZYS precision bearing, ball bearings, roller bearings, bearing parts

★ In September 1958, the spindle manufacturing department successfully developed China's first high-precision electric spindle. The electric spindle uses the speed of 30,000 ~ 60,000r / min for precision bearing grinding. ★ Through the efforts of several generations of spindle employees, ZYS has established its leading position in the field of high frequency Spindle spindle in China, and its research and development strength and spindles varieties rank first in China. ★ ZYS is the main drafting unit of spindle national standards, drafting and participating in a number of spindle standards. ★ ZYS is the deputy Director of Spindle Functional Components Technical Committee of China Machine Tool Industry Association. ★ ZYS is the undertaker of the 863 spindle project, the key unit responsible for the scientific and technological research and development of CNC machine tool spindles in the “Eighth Five-Year Plan”, “Ninth Five-Year Plan” and “Tenth Five-Year Plan”. ★ ZYS is the core unit...

The  electric  spindle is a kind of precision component with high speed and high rigidity. The  spindle  must be used strictly in accordance with the operating specifications, otherwise it will increase equipment failure and shorten equipment life. ZYS BEARING recommends the end user to follow the below rules during use: ⑴ Before starting the machine, first make sure that the spindle cooling system is working properly, and then turn on the electric spindle. It is strictly forbidden to use the spindle without cooling, so we must check whether the fan...

I. Structural composition of  electric spindle The electric spindle is a new technology that combines the machine tool spindle and the spindle motor in the field of CNC machine tools in recent years. The main drive system of high-speed CNC machine tools eliminates the belt drive and gear drive. The main shaft of the machine tool is directly driven by the built-in motor, which shortens the length of the main drive chain of the machine tool to zero and realizes the "zero drive" of the machine tool. This type of transmission structure intergrating spindle motor and machine tool spindle, which makes the spindle components relatively independent from the drive system and overall structure of machine tool, so it can be made into a "spindle unit", commonly known as electric spindle or Motor Spindle. The electric spindle is a set of components, which includes the electric spindle itself and its accessories: electric spindle, frequency conversion device, oil mist lubric...
