Using a CNC machining center friends can achieve the efficiency and speed of the machining center, but many manufacturers friend doesn't know processing center, also don't know the purpose of machining center. This article will take you into machining center CNC numerical control lathe manufacturer.

small vertical machining center is a kind of used for sheet metal processing machines, mold and shell parts. It can finish the machining processes such as drilling, milling, boring, but the price is higher, the processing consumption is much higher than the traditional manual machine tools, thus machining center can significantly shorten the item processing time. Therefore, the design of the machining center and machining efficiency and quality are closely related. So, machining centers have what advantage?< br / >
1。 The smaller the thermal deformation. Machine tool in cutting, no exception will generate heat, which in turn affect the machine tools, machine parts can produce different degree of thermal deformation, which affects the precision of processed products. How to reduce the heat impact on machining precision products is a problem. At present, we can improve the machine tool structure, make the machine tool of intangible thermal deformation in a direction we can control. For example, horizontal machining center pillar adopts frame type double column structure, left and right sides is symmetrical. Rising hot deformation of the spindle axis direction of translation. It can compensate by coordinate correction, in order to reduce heat, and as much as possible to separate heat source and the host.< br / >
2。 The static stiffness of the better. For machining center, machine bed, table, spindle box, guide rail and other parts of the structure stiffness is closely related to the accuracy of machine tool, so these factors require a machine has high static stiffness. In the cutting process, inevitably produces vibration, this will affect the machining accuracy and surface quality, it will also reduce the tool life, and the production efficiency have a significant impact. Machining center work for a long time, however, would not pass in the manufacturing process of artificial intervention and adjustment to eliminate the vibration. Therefore, the dynamic stiffness of machine tool needs to improve.< br / >

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:
By implementing the above key points, Swiss-type lathes can achieve high-precision, high-efficiency linear positioning, meeting the machining demands of high-precision fields such as aerospace, automotive manufacturing, and medical devices.
