How to choose the speed and feed of CNC vertical lathe?

CNC vertical lathe is a machining method that can efficiently process various types of workpieces, including metals, plastics and other materials. Among them, it is very important to choose the appropriate rotation speed and feed amount, because this will directly affect the processing efficiency and processing quality. So, how to choose the speed and feed of CNC vertical lathe? Let's learn more about it below.
First, to select the appropriate rotational speed, several factors need to be considered, such as workpiece material, tool type, and depth of cut. Among them, the workpiece material is one of the most important factors. Generally speaking, metal materials require lower rotational speeds, while plastics and other materials require higher rotational speeds. In addition, the tool type and depth of cut also have an impact on the rotational speed. It is recommended to conduct reasonable matching and testing according to the characteristics of the workpiece and tool before use to find the best rotation speed.
Secondly, to choose the appropriate feed rate, you also need to consider multiple factors. First, the hardness and strength of the workpiece need to be considered. If the workpiece is hard, the feed will need to be reduced to prevent overcutting and damaging the tool. Secondly, the tool type and depth of cut need to be considered. If carbide tools are used, the feed rate can be increased, but if the cutting depth is large, the feed rate needs to be appropriately reduced. Finally, factors such as the machine tool structure and coolant usage of the CNC vertical lathe need to be considered to determine the optimal feed amount.
In actual operation, in order to obtain the best processing efficiency and processing quality, the optimal rotation speed and feed amount can be determined through experiments and adjustments. Generally speaking, you can first choose a relatively reasonable rotation speed and feed rate based on the material, tool and workpiece size, and then perform trial cutting. If the tool jams or makes abnormal sounds during trial cutting, the rotation speed and feed amount need to be adjusted appropriately. On the contrary, if the trial cutting results are good, the rotation speed and feed rate can be appropriately increased to improve processing efficiency and processing quality.
In short, choosing the appropriate speed and feed is one of the key points that must be paid attention to in CNC vertical lathe processing. Only through experimentation and adjustment can the optimal parameter settings be found to achieve high efficiency and high-quality processing results.
