Improving Precision and Service Life through Fixture Adjustment and Maintenance


Fixture Adjustment Methods:


Fixture Maintenance Methods:


By properly adjusting and regularly maintaining fixtures, the machining accuracy and service life of Swiss-type lathes can be effectively improved, ensuring efficient and stable production processes.

The stress in a machine tool bed can influence machining quality in several ways:

Machining Accuracy


Deformation and Displacement: Stress in the bed can cause structural deformation, which in turn affects the positional accuracy of various machine components. For example, insufficient rigidity at the tailstock support of the bed may lead to positional deviations of the tailstock center, with maximum displacement deformation reaching up to 0.13465 mm. Such deformation directly impacts the relative positioning between the tool and the workpiece, resulting in machining errors.

In summary, the multi-process integration of Swiss-type lathes, achieved through advanced CNC systems, multi-axis linkage, power tools, and automation features, offers significant benefits in terms of precision, efficiency, and versatility. This integrated approach not only enhances production efficiency but also reduces costs, making Swiss-type lathes an ideal choice for modern manufacturing needs.

Differences in Machining Effects with Different Power Head Configurations


Single Spindle vs. Dual Spindle: Single-spindle Swiss-type lathes usually come with one side power head and are suitable for machining relatively simple parts. In contrast, dual-spindle lathes can be equipped with more power heads and can even perform simultaneous machining on the main and secondary spindles, significantly improving machining efficiency and complexity.


Side Tool Post vs. Horizontal Tool Post: Power heads with a side tool post structure perform better when machining difficult-to-chip materials, while those with a horizontal tool post structure are more efficient for machining easy-to-cut materials.


In summary, the power heads of Swiss-type lathes offer significant advantages in machining accuracy, efficiency, complexity, and adaptability. Different power head configurations can be selected based on specific machining requirements to achieve the best machining results.

Pitch compensation is an important means of precision improvement in CNC machines. By compensating for the pitch errors of the lead screw, it can significantly enhance the positioning accuracy and machining accuracy of the machine tool. The following is a detailed description of the methods, steps, and application cases of pitch compensation:
