How to control the temperature of the permanent magnet sucker grinding?

 The design and selection of the permanent magnet sucker requirements into account, the sucker in the

corresponding frequency range, to meet the load requirements attenuation characteristics, if a filter failure

Reductions can not meet the requirements of the alerts, and can adopt multi-cascade, can be obtained higher

attenuation than a single stage, the type of filter cascade can be obtained in a wide frequency band within good

Attenuation characteristics. So, how to control the temperature of the permanent magnet sucker grinding it?Magnetic Grid
   Permanent magnet sucker grinding process is often too late to pass in the depths of the workpiece, which gather the

formation of local high temperature in the surface layer. Workpiece surface temperature is often up to 1000 (in Table

The surface layer is formed great temperature gradient (up to 600 1000 [/ mm). Permanent magnet sucker grinding the

thermal effects village workpiece surface quality and performance a great impact.

Especially when the temperature at the interface exceeds a critical value, it will cause thermal damage of the table turns

(surface oxidation, burn, residual stress buckle crack). As a result will lead to

Parts of the anti-wear performance degradation, increased sensitivity to stress corrosion, fatigue resistance

deteriorates, thereby reducing the service life and the reliability of the permanent magnet sucker Part. Furthermore,neodymium block magnets

Accumulated temperature rise of the workpiece in the permanent magnet sucker grinding cycle, often leads to the

workpiece shape accuracy error of dimensional accuracy.
   Other -, the grinding heat of grinding zone, not only affect the workpiece, but also affect the life of the permanent

magnet sucker wheel. Thus, approximately the temperature in the grinding zone on the workpiece

Distribution, study of the permanent magnet sucker grinding wheel the effective abrasive grinding zone temperature to

study the distribution characteristics of the grinding burn before and after cutting temperature, is the study of the

grinding machine

Management and improve the integrity of the important issues of the grinding surface of the part.
