There are many reasons for the poor finish of lathe processed products, which need to be analyzed and solved from many aspects. Therefore, some causes and solutions for the poor finish of lathe processing products are summarized.
OneImproper choice of tools
The choice of tool has a crucial impact on the finish of the product machined by the lathe. If the tool is not selected properly, such as the lack of sharpness of the tool, the geometry of the tool is not suitable, etc., it can lead to a poor finish of the machined product.
Workaround:According to the processing material and processing requirements, select the appropriate tool to ensure that the sharpness and geometry of the tool meet the processing requirements.
IIThe feed rate is too fast
Excessive feed rates can lead to increased cutting forces and higher cutting temperatures, which can affect the finish of the machined product.
Workaround:Appropriately reduce the feed rate, reduce the cutting force and cutting temperature, and improve the finish of the processed products.
IIIInsufficient coolant or insufficient pressure
Coolant plays a role in cooling and lubrication during lathe machining, if the coolant is insufficient or the pressure is insufficient, it may lead to an increase in cutting temperature and an increase in cutting force, which will affect the finish of the machined product.
Workaround:Ensure that the coolant is sufficient and the pressure is sufficient to reduce the cutting temperature and cutting forces and improve the finish of the machined product.
FourthThe structure of the lathe itself
Problems with the structure of the lathe itself can also lead to poor finish of the processed product. For example, insufficient accuracy of the spindle, wear of the guide rails, etc., can affect the finish of the machined product.
Workaround:Carry out regular maintenance and maintenance of the lathe to ensure the accuracy and stability of key components such as the spindle and guide rails of the lathe.
FiveThe processing parameters are unreasonable
Unreasonable processing parameters may also lead to poor finish of the processed product. For example, too large a depth of cut, too high a rotational speed, etc., can affect the finish of the machined product.
Workaround:According to the processing materials and processing requirements, the processing parameters are reasonably set, such as cutting depth, rotation speed, etc., to improve the finish of the processed products.
SixImproper use of cutting fluid
The use of cutting fluid also has an important impact on the finish of the product machined by the lathe. If the cutting fluid is used incorrectly, such as too high or too low concentration, too high or too low temperature, etc., it can lead to poor finish of the machined product.
Workaround:According to the processing requirements and the characteristics of the cutting fluid, the cutting fluid is used reasonably to ensure that the concentration and temperature of the cutting fluid meet the requirements, so as to improve the finish of the processed products.
