NSK bearings abrasive grinding point temperature

Writer: Eric Bearing Limited

   Under normal circumstances, NSK bearings abrasive grinding points, from the New Territories North Region, the average temperature of the bearing grinding conditions and heat transfer theory analysis. When the wheel diameter D, six disc-shaped cutter, cutting machine grinding wheel, and the same number of cutting-edge distribution width;, the outer perimeter of the forefront of equal distribution of interval tools, cutting, grinding the cutting edge of the principles, to cut a single Ñ ​​maximum undeformed chip thickness and length Z. abrasive grinding wear debris can be drawn from the average temperature and tangential grinding force F. Wheel width is proportional to the effective sharpening unit length is inversely proportional to the number and the relationship between the width of the workpiece, grinding abrasive NSK bearings point temperature can be calculated.
(1) NSK bearing the average temperature distribution curve is smooth and continuous, near the peak position and a smooth curve around the end of the peak of the arc, so when the heat flux distribution along the arc of the creep feed grinding is continuous , closer to the triangular heat source distribution model.
(2) arc the average surface temperature is very low value, low arc low, indicating that normal creep feed grinding process NSK bearing surface temperature of the actual power generation is very low, which previously mentioned, creep feed grinding cutting process easier without the pressure of reason.
(3) average temperature contrast, NSK bearings abrasive grinding point temperature while high, but not much higher, which seems to reveal the normal creep feed grinding grinding the most enthusiastic, do not enter the workpiece. Grinding in a certain amount of duplication within the test conditions change that the average temperature and the corresponding changes in the proportion of measured, but over 13,012 more. This suggests that normal creep feed grinding surface when the average low temperature is confirmed that no doubt, some deep into the literature, slow grind back and forth when the temperature is definitely higher than normal grinding is essentially a misunderstanding.
