To Enlarge the Attention of Client on Mining Field

Installation - Dec 7 2013

Question:If the work piece bump hurt in the transfer process will be directly re-mapped to the machined surface of the raceway to affect bearing vibration. It must take the following measures: to improve the positioning benchmark surface shape accuracy; processing pass smooth no bump hurt; rough stay in the amount of form and position error can not be too large, in particular, leave the amount is small, too large error will cause the final grinding and ultra-fine shape accuracy has not improved at the end of the final quality requirements, seriously affecting the processing quality and consistency.
It is not difficult to see from the above analysis: automatic line of high performance, high stability of the machine tool system grinding and super finishing processing of low-noise ball bearing is the most appropriate, bump injuries can be avoided, reduce the transmission error, eliminate artificial factors, improve processing efficiency and quality consistency reduce production costs, improve enterprise efficiency.
Whether it is a ball or rings, waviness produced in the grinding machine price , super finishing can improve the waviness and reduce roughness, but the most fundamental measure is to reduce the waviness in the grinding of ultra-fine process. To avoid the randomness bump injury, there are two main measures:
First, to reduce the rolling surface grinding ultra-precision vibration, to get the good shape of the surface machining accuracy and surface texture quality in order to reduce vibration, grinding and super finishing machine must have a good vibration resistance, bed structure with vibration absorbers , stone crusher machine plant , super precision machine tools Whetstone oscillating system with good anti-vibration performance; improve grinding speed, the outer raceway commonly used foreign grinding 6202 60000 electric spindle, grinding speed 60m / s or more, the domestic general much lower , mainly affected by the spindle and limit of the main bearing performance.
The second is to improve the accuracy of machining datum and reduce grinding and supe finishing processing error reflection outside diameter and the face is locating datum in the process of grinding and supe finishing processing of mining machinery which is major in producing the sand maker such as the cone rock crusher , china jaw crusher , hammer crusher , compound crusher and mining grinder such as ball mill machine . Error reflection of outside diameter ultra-fine of the channel on the groove through the outer diameter grinding, groove grinding error reflection ditch super indirectly passed .
