徐州SKF轴承61909-ZN不同磨削形式的应用及利弊

表面磨削的形式和特点是不同的。

The forms and characteristics of surface grinding are different.

1,徐州SKF轴承外圆磨削的特点可以减少工件的热变形，提高磨削工件的精度。适用于各种工件的磨削。平面度误差控制在0.01～0.02/1000之间，表面粗糙度可达到0.8～0.2。但在不进行磨削的情况下，工件表面需要间断的水平磨削，生产效率低。

1. The characteristics of Xuzhou SKF bearing cylindrical grinding can reduce the thermal deformation of workpiece and improve the accuracy of grinding workpiece. It is suitable for grinding various workpieces. The flatness error is controlled between 0.01 and 0.02/1000, and the surface roughness can reach 0.8 to 0.2. But without grinding, the workpiece surface needs intermittent horizontal grinding, and the production efficiency is low.

2,端面磨削具有弯曲变形小、刚度好的特点，可选用较大的徐州SKF轴承磨削参数。生产效率高。工件容易发生热变形和温高损伤。仅适用于磨削精度低、形状简单的工件。

2. End grinding has the characteristics of ***all bending deformation and good stiffness. Large SKF bearing grinding parameters can be selected. High production efficiency. Workpieces are prone to thermal deformation and high temperature damage. It is only suitable for workpieces with low grinding accuracy and simple shape.

为了提高其端面磨削的质量，可以采取以下措施来解决这一问题：

In order to improve the quality of end grinding, the following measures can be taken to solve this problem:

1.选用粒径较大、硬度较软的树脂结合剂砂轮。轴承具有额定负荷高、噪音低、大大降低维护成本、延长机器运行时间等优点。当识别徐州SKF轴承的真实性时，通过触摸轴承上的钢印来识别轴承的真实性是更快、更准确的。这种***如果用手触摸就没有接触，但用钉子轻轻地触摸***就可以感觉到。

1. Choose resin-bonded grinding wheels with larger particle size and softer hardness. Bearing has the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time. When identifying the authenticity of Xuzhou SKF bearing, it is faster and more accurate to identify the authenticity of bearing by touching the steel stamp on the bearing. This kind of stamp has no contact if it is touched by hand, but it can be felt by touching the stamp gently with a nail.

在大多数情况下，轴承疲劳损伤会导致轴承疲劳损伤。一般来说，轴承疲劳损伤造成的损伤只有三分之一来自润滑不顺畅，三分之一来自污染物进入轴承或安装和处理不当。然而，徐州SKF轴承这些类型的损坏都是与工业轴承无关的精细零件，所以在使用高性能轴承时要小心，即使使用不当，也不能达到预期的性能效果，而且容易造成轴承损坏。

2.磨削时提供足够的切削液。

2. Provide enough cutting fluid for grinding.

3.用插入式砂轮打磨。

3. Grinding with insert grinding wheels.

4.为了减少砂轮与工件的接触，改良散热条件，将砂轮的端面改为内锥面中部，使砂轮与工件直线接触，或将磨头倾角调整为小角度。徐州SKF轴承具有额定负荷高、噪音低、大大降低维护成本、延长机器运行时间等优点。当识别轴承的真实性时，通过触摸轴承上的钢印来识别轴承的真实性是更快、更准确的。这种***如果用手触摸就没有接触，但用钉子轻轻地触摸***就可以感觉到。

4. In order to reduce the contact between grinding wheel and workpiece and improve the heat dissipation condition, the end face of grinding wheel is changed into the middle part of inner cone surface to make grinding wheel contact with workpiece in a straight line or adjust the inclination angle of grinding head to a ***all angle. Xuzhou SKF bearings h***e the advantages of high rated load, low noise, greatly reducing maintenance costs and prolonging machine operation time. When recognizing the authenticity of bearings, it is faster and more accurate to recognize the authenticity of bearings by touching the steel stamps on bearings. This kind of stamp has no contact if it is touched by hand, but it can be felt by touching the stamp gently with a nail.
