Adjust the method of numerical control lathe servo motor speed
want to change the synchronous servo motor speed can be used two ways: one is the numerical control lathe changes pole of logarithm, this is a step of speed method, it is based on the logarithmic stator winding wiring switch to change poles to end; Numerical control lathe and the other is frequency conversion speed, go through changes in motor power frequency to change the speed of the motor, it is communication synchronous motor speed control method of a kind of ideal, this method can end stepless speed regulation, the power and power factor are high. The first step of numerical control lathe frequency control of motor speed is to supply the motor with variable frequency power supply converter. CNC lathe factory inverter can be divided into pay a frequency conversion and continuously with two. Using the silicon controlled rectifier direct hand over frequency, electric power frequency communication ( Frequency 50 hz) Into low frequency pulse communication power, the power of fundamental wave pulse communication is required for variable frequency voltage. Numerical control lathe in continual frequency conversion method is first communication electric rectifier into direct current, then dc voltage into a rectangular pulse voltage, the rectangular pulse frequency voltage needed for the fundamental wave is. This method the communication power fluctuations small, FM frequency modulation scope is wide, scheduling good linearity. Straight on nc lathe often choose to pay a frequency control of motor speed. CNC lathe factory in hand in rectangular frequency conversion, according to the center of dc energy storage element is large capacitor is still on the road in the large inductance, can be divided into voltage type inverter and the current type inverter. Numerical control lathe SPWM inverter is now the most widely used, one of the most fundamental variable rectangular voltage { Applies to communication asynchronous motor, induction has been used widely in the communication transmission system.

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.
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.
