Techniques for adjusting the tailstock pressure of CNC machine tools and methods for improving processing efficiency

The Importance of tailstock pressure regulation for CNC Machine tools

In the processing of CNC machine tools, the adjustment of tailstock pressure is a crucial link. It not only affects the precision and efficiency of processing, but is also a key factor in improving processing quality. So, how to adjust the tailstock pressure of a CNC machine tool? Next, we will delve into this issue and share some practical adjustment tips.

Adjustment techniques and positions

The adjustment techniques and positions reflect the significance of regulating the tailstock pressure for machining accuracy. During the processing of CNC machine tools, the pressure borne by the tailstock is of vital importance, as it directly affects the stability of the workpiece and the accuracy of the processing. To ensure processing quality, we need to make appropriate adjustments to the tailstock pressure.

Connection plate adjustment

At the tail end of a CNC machine tool, there is usually a connecting plate, which is an important position for us to directly adjust the tailstock pressure. Through the connecting plate, we can easily adjust the pressure size that the tailstock bears to meet different processing requirements. However, when adjusting the tailstock pressure, the machine tool spindle must be turned off first to ensure the safety and accuracy of the operation.

Oil pressure tailstock adjustment

The hydraulic tailstock regulates the tailstock pressure through a hydraulic cylinder. The advantage of this method lies in its simple operation process and the ability to be adjusted while the machine tool is running, thus ensuring the high efficiency of machine tool processing.

Manual screw adjustment

In some traditional machine tool designs, the adjustment of tailstock pressure is accomplished by manually operating screws. The accuracy of this method is relatively low because it mainly relies on the specific conditions of the processed parts and the experience of the workers for adjustment.

Specific adjustment steps for CNC machine tools

The method for adjusting the tailstock pressure varies depending on the type of CNC machine tool and the tailstock structure. Next, we will take the commonly used hydraulic tailstock as an example for detailed explanation: Before starting to adjust the tailstock pressure of the CNC machine tool, the first step is to ensure that the machine tool spindle is completely closed and the tailstock working rod is in a loosened state. The pressure control valve on the hydraulic tailstock can be manually operated or adjusted accordingly through the numerical control panel. According to the specific requirements of the workpiece, the pressure of the tailstock is precisely adjusted to ensure that the processing accuracy and stability of the workpiece are reliably guaranteed. After precisely adjusting the tailstock pressure and confirming that it has reached the ideal state, the tailstock work rod needs to be retightened, and a comprehensive test of the adjustment effect should be conducted to ensure that the quality and stability of the processed parts are continuously guaranteed.

Common Problems and Solutions

After adjusting the tailstock pressure, if it is found that the position of the processed part needs to be corrected, this might be due to improper adjustment of the tailstock pressure or an irregular shape of the processed part. At this point, you can try adjusting the centerline of the tailstock to be consistent with the axis centerline of the processed part, or adjust the clamping method of the processed part to solve the deviation problem.

If the processing force of the tailstock is insufficient, the pressure setting of the tailstock should be re-examined. If necessary, appropriate adjustments should be made, or the wear-resistant material should be considered for replacement to enhance the processing force.
