Numerical control lathe spindle system fault diagnosis
common categories of nc machine tools to end more modern factory, medium and small batch of parts processing. Common nc machine tools are neway CNC lathe, milling machine and machining center, etc. To habits in nc machine tools of high automation, high plasticity, and the processing characteristics of high accuracy and rate of CNC lathe spindle system USES its unique methods and structure. The mechanical structure of the CNC lathe spindle: 1. Spindle ladder for a hollow shaft. 2. End of choosing short conic flange structure in collaboration with the chuck body; 3. After the spindle end first for equipment rotary oil cylinder; 4. Hollow spindle used by rotary oil cylinder piston rod; 5. Transmission methods are gear transmission, synchronous belt and belt mixed with gear transmission. Numerical control lathe electrical structure: 1. Drive for bridging nc equipment and spindle motor; 2. Completion of photoelectric pulse encoder, spindle speed real-time inspection, which constitute the main electrical control system; 3. Completion of rotary cylinder hydraulic control circuit, chuck jaw clamping and loosening. Nc lathe spindle system fault features: the main shaft system problems also can be divided into mechanical faults and electrical fault. Some mechanical structure as mentioned above, it is well known that a brief in the part of the problem is who often do the rotary motion, linear motion components, so find something wrong with parts should first preliminary from these parts. Vertical CNC processing base, for example, appeared to hold the cutting tool, should first check if broach rod stroke changes, due to broach rod during tool change again and again, often do linear motion. Some including spindle spindle system of electrical motor, drive, CNC equipment, spindle speed inspection equipment, parking equipment. Brief faulty is spindle motor, the spindle speed inspection equipment, must stop. Fault diagnosis method: generally speaking, a mechanical problems compared to short notice, and electrical fault diagnosis difficulty will be larger. Nc rotary working table commonly so judging mechanical some first whether there is something wrong with, then discriminant electric is some existing problems. First find out the machine tool spindle assembly from the mechanical structure, inspection of these components is normal or not. From experience, CNC machine tool spindle with large some of them are mechanical action failure cause. So, follow after the first mechanical electrical diagnosis method, generally can reach the role of get twice the result with half the effort.
Nowadays, it is very common for us to utilise in multi axis cnc machine. And the quality of is decisive to production efficiency.
If you already use cnc service elsewhere or want the ability to offer restricted chat access to certain individuals, cnc service mill axis offers you the most flexibility.
Zhongshan JSTOMI CNC Machine Tool Co., Ltd. has extented its range of manufacturing scale, which satisfys customers' needs.
We utilize our expertise to develop services that add value at each phase of thecnc service development cycle. We evaluate and implement new strategies in response to changing customer profiles and market conditions.
Methods to Reduce the Impact of Force-Induced Deformation
To minimize the impact of force-induced deformation on the stability of Swiss-type lathes and enhance machining accuracy and stability, the following measures can be taken:

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.
