The machining center is an efficient and precise CNC machine tool, mainly used for precision machining of parts. During the operation of a machining center, cutting feed rate is a very important parameter. The cutting feed rate refers to the distance that the tool moves in one cutting on the work table. It is generally expressed in mm/min as the unit. It has a very important impact on the processing efficiency and processing quality of the CNC machining center.
How should the cutting feed speed of a machining center be determined? When performing CNC machining, the most appropriate cutting feed rate can be determined based on factors such as the hardness, size, shape of the workpiece material and the type, material and wear of the cutting tool. If the cutting feed speed is too slow, the processing efficiency of the parts will be low, the processing time will be extended, and the cost will increase. If the cutting feed speed is too fast, it will increase the tool wear rate and even cause the tool to break, affecting the processing quality and safety.
In response to the requirements of different materials and processing methods, the feed speed and rotation speed of the machining center need to be flexibly set according to the actual situation. When processing hard materials or high-precision small holes, the feed speed is generally slower to ensure processing accuracy and surface quality. When processing soft materials, the feed speed is generally faster, which can greatly improve production efficiency.
In addition, the feed speed and rotation speed of the machining center need to be flexibly adjusted according to the wear and performance of the cutting tools. In order to ensure the stability of the machining effect, tools generally need to be inspected and replaced regularly. At the same time, the feed speed and rotation speed can be appropriately increased or reduced according to the performance and durability of different cutting tools to achieve the best processing effect.
In short, the cutting feed speed is an important parameter in the operation of the machining center. The feed speed and rotation speed must be reasonably adjusted and controlled according to the requirements of different workpieces to improve processing efficiency and processing quality.
