How to adjust the center height of a single-column CNC vertical lathe

The center height is the vertical distance from the center line of the machine tool spindle to the plane of the machine tool base. The purpose of adjusting the center height is to ensure that the relative position between the tool and the workpiece during the processing is accurate, thereby improving the processing accuracy and efficiency.

So, how to adjust the center height of a single-column CNC vertical lathe? Next, I will introduce the entire adjustment process to you in detail.

1. Preparation

Before adjusting the center height, you must first make adequate preparations. This includes checking the integrity of the various parts of the machine tool, cleaning up debris on the workbench and fixtures, and ensuring that the power and air supply are normal. At the same time, you also need to prepare the required tools, such as measuring rulers, micrometers, wrenches, etc.

2. Installing tools and fixtures

Next, install the tool to be processed on the tool holder and install the fixture so that the workpiece can be stably fixed on the workbench. During the installation process, pay attention to the accuracy and firmness of the tool and fixture to ensure that they will not have an adverse effect on the processing process.

3. Rough adjustment of center height

Move the workbench to a suitable position manually or electrically so that the cutting edge of the tool is roughly flush with the surface of the workpiece. At this point, you can use tools such as a measuring ruler to make preliminary measurements to ensure that the relative position between the tool and the workpiece is roughly correct.

4. Fine-tune the center height

Fine-tune the center height is a key step in the adjustment process. In this step, we need to use precision measuring tools such as a micrometer to measure the relative position between the tool and the workpiece. The specific method is as follows:

Fix the micrometer in the appropriate position of the machine tool so that it can measure the distance between the tool cutting edge and the workpiece surface.

Slowly move the workbench so that the tool cutting edge gradually approaches the workpiece surface. During the movement, carefully observe the changes in the reading of the micrometer and stop moving when the reading is close to zero.

At this point, you can fine-tune the height of the tool holder or workbench to make the tool cutting edge completely flush with the workpiece surface. During the fine-tuning process, repeatedly measure and observe to ensure the accuracy of the adjustment result.

5. Trial cutting verification

After the adjustment is completed, a trial cutting verification is required. During the trial cutting process, pay attention to observe whether the processing effect and processing accuracy meet the expected requirements. If it is found that the processing effect is not good or the processing accuracy does not meet the requirements, it is necessary to readjust the center height and perform another trial cutting verification.

VI. Precautions

In the process of adjusting the center height of a single-column CNC vertical lathe, the following points should be noted:

During the adjustment process, the stability and accuracy of the machine tool should be maintained to avoid vibration and errors.

When using measuring tools, ensure their accuracy and reliability to avoid measurement errors.

During the adjustment process, careful observation and measurement should be made to ensure the accuracy of the adjustment results.

During the trial cutting verification, the operation should be strictly carried out in accordance with the processing requirements and process parameters to ensure the stability of the processing effect and processing accuracy.

Through the introduction of the above steps, I believe you have a clear understanding of how to adjust the center height of a single-column CNC vertical lathe. In actual operation, flexible adjustments should be made in combination with specific processing requirements and equipment conditions.
