In the field of CNC lathe processing,Datong Okuma CNC LatheIt is favored for its high precision and stability. As a key part of the operation of CNC lathes, tool adjustment is precise and directly affects the processing precision and quality. Below I will reveal how to adjust the knife.
1. Tool adjustment on the X axis
First, perform tool calibration on the X axis of the cylindrical turning tool. Install the tool on the tool holder, start the Datong Okuma CNC lathe, manually operate the tool close to the workpiece along the Z axis direction, and then cut the outer circle of the workpiece. Note that do not move the X axis coordinates yet. When the cut is complete, retract the tool along the Z axis and stop the spindle rotation. Use vernier calipers to accurately measure the diameter of the outer circle you just turned. Then enter the tool offset page of the CNC system, search for the corresponding tool number, enter the measured diameter value, and the system will automatically calculate and store the tool offset value in the direction of X axis.
If you are using an internal hole turning tool, the steps are similar. Only after turning the inner hole is the diameter of the inner hole measured. The measured value is also entered into the corresponding position on the tool compensation page to complete the tool calibration on the X axis.
2. Tool adjustment on Z axis
For setting a tool on the Z axis, whether it is an external turning tool or an internal hole turning tool, the operation is basically the same. Manually control the tool to approach the workpiece along the X-axis direction, and then cut the end face of the workpiece. After cutting, retract the tool along the X-axis direction, keeping the Z-axis coordinate unchanged. Enter the tool compensation page of the CNC system and enter “0” in the Z axis compensation position corresponding to the tool number. This completes the Z-axis tool calibration and determines the zero point position of the tool in the Z-axis direction.
3. Thread knife adjustment
Adjusting the thread cutter is relatively complicated. In addition to basic tool setting operations on the X and Z axes like external turning tools, special attention should be paid to the tip angle and installation position of the threading tool. Since thread processing requires extremely high tool position accuracy, when installing a thread cutter, ensure that the tip of the thread cutter is at the same height as the center of the part and that the profile angle of the tool is consistent with that of the wire being processed. During the tool setting process, the X and Z axis tool setting methods are the same as ordinary tools, but before thread processing, it is necessary to further check and refine the position of the tool when cutting the thread to ensure the precision of thread processing.
4. Setting up tools with multiple tools
When multiple tools are used for processing, after the calibration of the first tool is completed, the calibration of subsequent tools can be based on it. Install the following tools on the tool holder in order, carry out trial cutting operations in the X and Z axis directions, measure the difference with the first tool in the X and Z directions, and then input the difference into the corresponding tool number. of the CNC system. In the compensation value, the setting of multiple tools can be completed.
Mastering the tool setting method of Datong Okuma CNC lathe requires patience and care. Each step of the operation must be precise to ensure that the tool is in the best position during the processing process, thereby processing high-quality parts that meet precision requirements. Through continued practice and practice, operators can skillfully use these tool setting methods to maximize the efficiency of CNC lathes.
