The higher the speed of the lathe machining, the higher the surface finish of the parts.
1. The influence of rotation speed on the surface finish of parts in lathe processing
In lathe machining, rotational speed has an important influence on the surface finish. The conventional wisdom is that the faster the rotational speed, the faster the cutting speed and the higher the surface finish. But in fact, rotational speed is not the only factor that affects the surface finish.
Second, speed is not the only influencing factor
1. Material factors
Different materials have different processing behaviors. For the same speed and cutting feed, the finish of brass is better than that of more difficult materials such as ferritic stainless steel.
2. Tool factor
The geometry of the tool and the condition of the cutting edge also have an impact on the surface finish of the part. The right tool selection can help improve machining accuracy.
3. Lubricant factor
Lubricants can sometimes affect the friction and wear of the turning tool against the workpiece. In some special cases, the addition of lubricants will improve the finish of the machined surface.
3. How to improve the surface finish of lathe processing
1. Choose the speed reasonably
Although rotational speed is not the only factor that affects the surface finish, choosing the appropriate rotational speed can ensure the cutting effect and improve the surface finish of the part.
2. Suitable knives
The right tool selection can guarantee the machining results and improve the surface finish of the parts.
3. Scientific lubricant selection
In some special cases, the addition of lubricants can improve the finish of the machined surface.
To sum up, the composition of the surface finish of the lathe machined parts is complex, and it must not be simply denied or affirmed that the faster the lathe speed, the higher the finish. Instead, it is necessary to comprehensively consider factors such as lathe speed, material, tool, lubricant, etc.
