Today to introduce the slant bed CNC lathe is strong electric control system of ordinary relay contactor control system and PLC programmable controller maintenance knowledge:
< br / >
1. Ordinary relay contactor control system maintenance in addition to the CNC system, the economical nc machine tools and common relay contactor control system. Its maintenance and maintenance work, mainly is how to take measures to prevent the high voltage cabinet of contactor, relay strong electromagnetic interference problem. Slant bed CNC lathe of high-voltage electrical cabinet of the contactor, relay and other electric components are the interference sources of CNC system. Because of ac contactor, frequent of ac motor start, stop, the control circuit of the electromagnetic induction phenomenon will make the CNC system produce the noise, such as peak or the wave surge interfere with the normal work of the system.< br / >
so must take actions to these electromagnetic interference, eliminated. For ac contactor coil, for example, in its both ends or three-phase ac motor input parallel RC network to suppress these electrical noise interferences. In addition, attention should be paid to prevent the oxidation of contacts of contactor, relay and contactor of poor contact, etc.< br / >
2。 Maintenance of PLC programmable controller< br / >
PLC programmable controller and slant bed on numerical control lathe important electrical control part. High voltage control system except with auxiliary motion of the auxiliary machine tool movement and control, also including the protection switch, all kinds of stroke and the limit switch control.< br / >
at the above process, the PLC programmable controller to replace most of the high voltage control system in machine tool machine tool electrical appliances, so as to realize the spindle, tool change, lubrication, cooling, hydraulic, pneumatic logic control system. PLC programmable controller and numerical control device is one of the built in PLC, and the numerical control device form the independent type PLC outside. Because the structure of the PLC and CNC devices have similarities, so you may refer to the maintenance of CNC equipment maintenance and maintenance.< 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.
