Slant bed CNC lathes do not have any special requirements for the general operating environment. They can be placed in the consumer workshop like ordinary machine tools, but to prevent direct sunlight and other heat radiation, to prevent places that are too humid or too dusty , Especially to prevent the place with corrosive gas. Corrosive gases are the easiest to cause the electronic components to be corroded and transformed, or to form poor contact, or to form short circuits between components. This will affect the normal operation of the machine tool. Keep away from equipment with large vibration, such as punching machines and forging equipment. Regarding high-precision CNC machine tools, anti-vibration measures (such as anti-vibration grooves, etc.) should also be taken.
Slant bed CNC lathes do not have any special requirements for power supply. Generally, they are allowed to shake ± 10%, but due to the specific situation of power supply in China, not only the power supply shakes large (sometimes far beyond 10%), but also the quality is poor. It is often superimposed with some high-frequency clutter signals, which can be clearly observed with an oscilloscope, and sometimes there are instantaneous interference signals with a large amplitude, destroying the sequence or parameters of the CNC system, and affecting the normal operation of the machine tool. Inclined bed CNC lathes are powered by dedicated lines (separately from the low-voltage power distribution room for CNC machine tools) or add voltage stabilization equipment, which can reduce the impact of power supply quality and reduce electrical disturbance.
Dividing the machining process of CNC lathe for inclined bed:
1. Cutter centralized sorting method
Is to divide the process according to the tool used, and use the same tool to finish all the parts that can be completed on the part.
Use the second knife and the third to complete other parts that they can complete. In this way, the number of tool changes can be increased, the lost motion can be shortened, and unnecessary positioning errors can be increased.
2. Processed parts sorting method
For parts with a lot of processing content, according to their structural characteristics, the processing part can be changed into several parts, such as internal shape, shape, curved surface or three-dimensional. Generally, the three-dimensional, positioning surface is processed first, and then the hole is processed; the complex geometric shape is processed first, and then the complex geometric shape is processed; the part with lower precision is processed first, and the part with higher precision is required.
3. Roughing and finishing machining sequential method
For parts that are prone to machining deformation, due to the deformation that can occur after roughing, it is necessary to stop the shape correction, so in general, to stop roughing and finishing, the process must be separated.
In summary, when dividing the process, we must be sensitive to the structure and manufacturability of the parts, the function of the machine tool, the number of parts CNC machining, the number of devices and the consumption organization of the unit. It is also recommended to use the criterion of centralized process or the criterion of dispersed process, which should be determined according to the actual situation, but it must be reasonable.
