Double disc grinding machine collapsed angle causes and treatment measures

As a kind of high-efficiency and precise processing equipment, double face grinding machine is widely used in the surface grinding processing of various metal materials. However, in practice, the problem of grinding corner collapse (i.e. excessive wear of workpiece corners) occurs from time to time, which not only affects the processing quality, but also increases the production cost. In this paper, we will discuss the reasons for the collapse of double face grinding machine, and put forward the corresponding processing measures.

Analysis of the causes of corner collapse

The reasons for the collapse of the double face grinding machine is multi-faceted, mainly involving the benchmark base plate, the benchmark grinding wheel, the relative position of the guiding platen and the grinding angle of the grinding wheel and other factors.

1. Improper grinding angle of the grinding wheel: when grinding, if the amount of grinding is concentrated in a certain section of the grinding wheel, it will lead to the rapid wear of the grinding wheel in that section, which in turn will cause uneven grinding of the workpiece and serious wear of the corners.

2. Poor parallelism between the base plate and the grinding wheel: If the parallelism between the inlet and outlet base plates and the grinding wheel is not properly adjusted, it will lead to uneven force on the workpiece in the grinding process, resulting in a collapsed corner.

3. Unreasonable gap between the guiding platen: If the gap between the guiding platen and the reference base plate is too large or too small, it will affect the stable passage of the workpiece, which will in turn affect the grinding quality. Too large a gap may lead to workpiece deflection, too small a gap may produce interference.

4. Reference grinding wheel position relationship is not appropriate: the position of the reference grinding wheel if below or above the exit reference base plate too much, will affect the grinding effect, resulting in the collapse of the angle.

The grinding wheel grinding surface is not flat: the linear speed of the grinding wheel running from the outer edge to the centre gradually decreases to zero, the outer edge of the consumption of fast, easy to appear in the convex phenomenon. If the grinding wheel profile is not flat, it will lead to uneven grinding force, which in turn will produce the collapsed angle.

Treatment Measures

For the above reasons, we can take the following treatment measures to prevent and solve the problem of collapsing angle of double face grinding machine:

1. Adjust the grinding angle of the grinding wheel: Check and adjust the grinding angle of the grinding wheel regularly to ensure that the grinding volume is evenly distributed on the grinding wheel during grinding and to avoid excessive wear of a certain section of the grinding wheel.

2. Check and adjust the parallelism between the reference base plate and the grinding wheel: Use professional inspection tools to regularly check the parallelism between the inlet and outlet reference base plates and the grinding wheel, and make necessary adjustments.

3. Reasonable adjustment of the clearance of the guiding platen: According to the size of the workpiece and grinding requirements, reasonably adjust the clearance between the guiding platen and the reference base plate to ensure that the workpiece can pass through stably and freely.

4. Adjust the position of the reference grinding wheel: make sure that the position of the reference grinding wheel is higher than the exit reference base plate by 0.02~0.03mm to achieve the best grinding effect.

5. Trimming the grinding surface of the grinding wheel: regularly check the flatness of the grinding surface of the grinding wheel and use professional trimming tools to keep the grinding surface of the grinding wheel flat.

In summary, the solution to the problem of collapsing angle of double face grinding machine needs to start from many aspects, including adjusting the grinding angle of the grinding wheel, checking the parallelism between the reference base plate and the grinding wheel, reasonably adjusting the clearance of the guiding platen, adjusting the position of the reference grinding wheel, and dressing the grinding wheel profile, etc. By implementing these measures, we can effectively solve the problem of collapsing angle of the grinding wheel. By implementing these measures, we can effectively prevent and solve the problem of collapsing angle of double endface grinding machine, and improve the processing quality and production efficiency.
