The double-column CNC machining CNC lathe is a high-precision and high-efficiency machining equipment. When using double-column CNC machining CNC lathes, tool setting methods and techniques are particularly important. Only correct tool setting methods and techniques can ensure processing accuracy and efficiency. Next, let’s learn about the methods and techniques of tool setting for double-column CNC machining CNC lathes.
Method 1: Observe the workpiece
When using double-column CNC machining CNC lathe tool setting, you must first observe the workpiece. The workpiece should be placed in the center of the CNC lathe, concentric with the lathe, and rotate slightly at the same time to check whether the distance between the tool and the workpiece is suitable. If you find that the distance between the tool and the workpiece is not appropriate enough, you need to adjust the position of the workpiece until the distance is appropriate.
Method 2: Use a tool setter
When using a double-column CNC machining CNC lathe, a tool setter can also be used for tool setting. The tool setter is a tool specially used for tool setting. It measures the distance between the tool and the material being processed through the contact induction between the tool setter and the tool. When using a tool setter, you need to install the tool setter on the turning tool holder first, and then determine the coordinate position of the tool setter. Then, the tool checker comes into contact with the tool, measures the distance between the tool and the workpiece, and makes adjustments.
Method 3: Refer to the craft card
Before processing, we should make a process card. The process card usually contains information such as the installation position of the bracket, the placement of the fixture, processing control parameters, workpiece dimensions and their tolerances. By referring to the process card, we can have a good understanding of the parameters and processing goals we need to control, so as to formulate a correct tool setting strategy.
Tip 1: Adjust the positive and negative gaps
When using a double-column CNC lathe, there is usually a certain positive and negative gap between the tool and the workpiece. At this time, we need to make appropriate adjustments to the positive and negative gaps to ensure that the tool can correctly contact the material being processed. Therefore, we need to fine-tune the adjustment screw on the tool holder until the positive and negative gaps are balanced to ensure that the cutting force is reduced during processing.

Tip 2: Adjust the inclination
When using double-column CNC machining CNC lathe tool setting, if it is found that the distance between the tool and the workpiece is not close enough, and the cutting force load is also large, this is because the inclination between the tool and the workpiece has not been reasonably adjusted. At this time, we can loosen the clamping screw and rotate the tool to adjust the inclination until the distance between the tool and the workpiece reaches the optimal state.
When using double-column CNC machining CNC lathe tool setting, the above methods and techniques are very practical. Through our proficiency and flexible use, we can effectively improve processing efficiency and accuracy. Therefore, it is necessary to pay more attention during daily use and apply it to actual production according to the actual situation.
