南京NSK轴承61919无心磨削工序的基准面

外径是南京NSK轴承零件加工的基准面。由于凹槽是无意的，外径是理想的圆柱体，只要它是支撑表面。只有这样才能达到磨削后的理想形状。但要达到理想的圆柱体是不可能的。

The outer diameter is the datum of Nanjing NSK bearing parts processing. Because the groove is unintentional, the outer diameter is an ideal cylinder, provided that it is the supporting surface. Only in this way can we achieve the ideal shape after grinding. But it is impossible to achieve the ideal cylinder.

因此，在此过程中，参考圆的圆度应尽可能低，特别是稀疏波的值，即从椭圆到15边的值。为了达到这个值，应采取以下措施：砂轮要动态平衡：正确选择导板高度、导轮角度和砂轮；前后导环要通过砂轮才能达到圆度。南京NSK轴承工艺参数根据TE进行调整。在连续生产中，每小时画两个圆，圆度用来测量圆度。

Therefore, in this process, the roundness of the reference circle should be as low as possible, especially the value of the sparse w***e, that is, the value from the ellipse to the 15 sides. In order to achieve this value, the following measures should be taken: the wheel should be dynamically balanced: correct selection of guide plate height, guide wheel angle and grinding wheel; front and rear guide rings must pass through the grinding wheel to achieve roundness. The technological parameters of NSK bearing in Nanjing are adjusted according to TE. In continuous production, two circles are drawn per hour, and roundness is used to measure roundness.

如前所述，只要对上述两个基准进行适当处理，超精加工后的沟槽和圆度纹波就不会产生问题。这两个过程应确保表面粗糙度和沟槽形状。因此，须注意合理选择砂轮、油石、切削参数和磨削液来清洗过剩，有条件的企业可以使用南京NSK轴承磨削液，超集中过滤供给。

As mentioned earlier, as long as the above two benchmarks are properly treated, the groove and roundness ripple after superfinishing will not cause problems. These two processes should ensure surface roughness and groove shape. Therefore, attention should be paid to the rational selection of grinding wheel, oil stone, cutting parameters and grinding fluid to clean excess, conditional enterprises can use Nanjing NSK bearing grinding fluid, ultra-centralized filtration supply.

除了滚动表面的缺点是影响振动的一个因素，其次是***的冲击，***有两个来源：其一，轴承零件在工作过程中残留的磨粒和灰尘；退磁是清洗的前提。清洗行业存在两个问题，一是清洗重质产品，二是忽视清洗液的质量。

In addition to the shortcomings of the rolling surface is a factor affecting vibration, followed by the impact of foreign bodies, foreign bodies h***e two sources: first, bearing parts in the working process of residual abrasive particles and dust; demagnetization is the premise of cleaning. There are two problems in the cleaning industry. One is to wash he***y products, the other is to ignore the quality of the cleaning fluid. Two.

事实表明，只有清洁南京NSK轴承产品是非常困难的。即使成品可以被清洗，剩余的磨料颗粒和污垢也可以很容易地划伤滚动表面。因此，我们应该高度重视零件的清洗。建议零件清洗两次，研磨一次后清洗，并在一次装配前清洗。喷雾可用于清洗。过滤器须在一个或两个阶段过滤，以提高清洁溶液的清洁度。

Facts show that only cleaning Nanjing NSK bearing products is very difficult. Even if the finished product can be cleaned, the remaining abrasive particles and dirt can easily scratch the rolling surface. Therefore, we should attach great importance to the cleaning of parts. It is recommended that the parts be cleaned two times, cleaned once after grinding and cleaned before one assembly. Spray can be used for cleaning. The filter must be filtered in one or two stages to improve cleanliness of the cleaning solution.
