In fact, the measured runout on the machine tool is not just the runout of the tool handle, but the embodiment of the integrated runout of the whole system in which the machine tool spindle, the tool handle and the cutting tool (or measuring rod) are clamped together. This runout is not only related to the machine tool, tool holder and cutting tool, but also related to the standard clamping method and operation (such as whether the tool holder vertebral handle and jacket are clean, etc.).

Many customers will find in the process of using the tool handle that the runout of the tool handle on the machine tool is very large, and many customers suspect that there is a problem with the tool handle. Is there really a problem with the handle? Here are some analyses:

In fact, the measured runout on the machine tool is not just the runout of the tool handle, but the embodiment of the integrated runout of the whole system in which the machine tool spindle, the tool handle and the cutting tool (or measuring rod) are clamped together. This runout is not only related to the machine tool, tool holder and cutting tool, but also related to the standard clamping method and operation (such as whether the tool holder vertebral handle and jacket are clean, etc.).

However, measured on the machine tool handle runout small must be able to explain the tool handle runout accuracy? In fact, not necessarily! On the same spindle with large runout, a tool handle with good runout accuracy and a tool handle with poor runout accuracy are respectively installed to measure the runout, and the results obtained may be just the opposite. Even if it is the same spindle with the handle, the handle rotates 180 degrees before and after two times to the spindle to measure the amount of runout, the results may be completely different.

After the above analysis, want to measure the tool handle on the machine tool runout accuracy is good or bad:

First of all, to ensure that the machine tool spindle runout accuracy is trustworthy. You can use the rod in advance to measure whether the runout accuracy of the machine tool spindle is within the required range.

2, to ensure that the machine tool spindle, handle and cutting tools, such as all with the surface clean, while ensuring that the correct method of operation.

However, if the handle is often measured at the customer's site, the customer will first suspect that it is the handle. Here is a method that can quickly determine whether it is a tool handle problem or a machine tool spindle problem in this case:

First, mark the position of the tool holder corresponding to the maximum runout value, then rotate the tool holder by 180 degrees and install it on the machine tool spindle to measure the runout. If the maximum runout value is still near the position marked by the tool holder, there is a problem with the tool holder. If the maximum runout value appears near the relative position of the handle mark, there is a problem with the spindle.
