The methods for ensuring dimensional accuracy of CNC vertical lathes mainly include the following aspects:

Choose reasonable tool materials and angles: The choice of CNC vertical lathe tools directly affects the machining accuracy. Choosing tools with appropriate materials and angles can improve cutting efficiency and processing accuracy, reduce tool wear and deformation, and ensure the stability of processing dimensions.

Analyze the processability of processed parts: Before processing, the CNC vertical lathe fully analyzes the processability of the parts, formulates a scientific processing plan, and clarifies the processing sequence and process parameters. This helps reduce errors and deformations during processing and improves dimensional accuracy.

Pay attention to the impact of the quality of the CNC vertical lathe on the cutting tools: the performance stability of the CNC vertical lathe has an important impact on the life and processing accuracy of the cutting tools. Choosing a CNC vertical lathe with stable performance and high precision can reduce tool wear and deformation and ensure the accuracy of processing dimensions.

Optimize CNC vertical lathe processing programming: The rationality of CNC vertical lathe programming is directly related to processing accuracy. Optimizing programming includes ensuring comprehensive and reasonable optimization of the programming origin, using multiple methods to process programming data information, and clarifying the rationality and efficiency of vertical lathe processing routes. These measures help reduce programming errors and improve machining accuracy.

Manual trial cutting and measurement: The CNC vertical lathe makes the tool slowly approach the workpiece by shaking the handwheel. When the tool is a certain distance from the workpiece, adjust to the minimum magnification gear for trial cutting. After trial cutting, use appropriate measuring tools (try to avoid using digital calipers) to measure the workpiece to ensure that the dimensional accuracy is within the required range.

Modify the tool offset value to ensure dimensional accuracy: If the CNC vertical lathe causes the workpiece size to exceed the tolerance range due to tool setting errors or other reasons, the error can be corrected by modifying the tool offset value so that the workpiece reaches the required dimensional accuracy.

Improve the comprehensive quality of technicians: CNC vertical lathe technicians need to continuously improve their skills, combine the actual needs of CNC system construction, processing and production, scientifically select the location of machine tool foundation construction, isolate interference sources, plan and manufacture anti-shock grooves, and avoid interference sources. The impact of machine tool manufacturing production accuracy. At the same time, technicians also need to scientifically and effectively implement the CNC system construction plan according to the CNC vertical lathe machining system construction parameters to ensure that the CNC vertical lathe machining accuracy is within a controllable range.

To sum up, ensuring the dimensional accuracy of CNC vertical lathes requires comprehensive consideration of multiple aspects, including control and optimization in many aspects, including tool selection, process analysis, machine tool performance, programming optimization, and manual trial cutting and measurement.
