Published Time:
Dec 18,2021
The research and development, and production of five-axis machining centers have a significant impact on the research and development and production of a country's aerospace, military, scientific research, precision instruments, and high-precision medical equipment industries. For the processing of parts such as engine impellers, wind turbine blades, marine propellers, heavy generator rotors, turbine rotors, and large oil pump crankshafts, the five-axis machining center is the most important CNC machining and production equipment.
The research and development and production of five-axis machining centers have a significant impact on the research and development and production of a country's aerospace, military, scientific research, precision instruments, and high-precision medical equipment industries. For the current processing of engine impellers, wind turbine blades, marine propellers, heavy generator rotors, turbine rotors, large oil pump crankshafts, and other accessories, the five-axis machining center is the most important CNC machining and production equipment.
A five-axis machining center can also be called a five-axis linkage machining center. This type of machining has five coordinate motion axes, namely two rotary motion coordinate axes and three linear motion coordinate axes. Five-axis machining centers are more suitable for processing complex parts with multiple processes, high precision requirements, and requiring various types of ordinary machine tools and numerous tools and fixtures, and which can only be processed after multiple clamping and loading.
Below, Xiaonuo will introduce what types of parts are suitable for Nobot five-axis machining centers:
1. Box-type parts
Five-axis machining centers can process box-type parts. Box-type parts mainly process multiple-position pores and planes. The processing precision requirements for box-type parts, especially those with strict shape processing precision requirements, are high. Generally, they must undergo multiple processes such as milling, drilling, expanding, boring, reaming, and tapping, requiring various types of tools, and using many tools. Box-type parts are difficult to process on ordinary machine tools, requiring multiple clamping and alignment, and it is difficult to guarantee processing accuracy. It is generally more suitable to use horizontal machining centers to process box-type parts, but five-axis machining centers can also process them.
2. Complex curved surface type parts
Complex curved surface type parts frequently appear in machinery, aerospace, and aviation. It is difficult or even impossible to process complex curved surface type parts using ordinary CNC machine tools. Common complex curved surfaces include: impellers, spherical surfaces, blades on turbine engines, various curved surface-shaped molds, marine propellers, underwater vehicle propellers, and other freely combined curved surfaces. These complex curved surface type parts are most suitable for processing using five-axis machining centers. The programming workload for processing complex curved surface type parts using five-axis machining centers is relatively large, and automatic programming technology is used for programming complex curved surface type parts.
3. Irregularly shaped parts
Irregularly shaped parts refer to irregular parts, such as workpieces with multiple positions of points, lines, and surfaces mixed together. Generally, the rigidity of irregularly shaped parts is relatively poor, so it is difficult or even impossible to process them using ordinary CNC machine tools. During processing, clamping pressure is difficult to control, and processing accuracy is difficult to guarantee. However, using a five-axis machining center is different. By adopting reasonable process measures for the five-axis machining center and utilizing the characteristics of mixed processing of multiple positions of points, lines, and surfaces in the five-axis machining center, multiple processes or all processes can be completed.
4. Molds
Such as injection molds, rubber molds, vacuum forming molds, refrigerator foaming molds, pressure casting molds, and precision casting molds, etc.
Using machining centers to process molds, due to the high degree of process concentration, the fine machining of key parts such as the moving mold and the fixed mold is basically completed in a single clamping, which can reduce the cumulative error of dimensions, reduce the amount of fitting work, and at the same time, the mold has strong reproducibility and good interchangeability. The amount of work left to the fitter in mechanical processing is small, and wherever the tool can reach, it should be completed by mechanical processing as much as possible.
Currently, Nobot five-axis machining centers have been widely used in industries and fields such as thermoforming, home appliances, crafts, sanitary ware, mold manufacturing, automotive interiors, rail transit, and aerospace, and are used for processing ABS, PP, plastics, polystyrene foam, resin, gypsum, wood, chemical plates, carbon fiber, and glass fiber composite materials.

Nobot was invited to attend the Belt and Road International Exchange Conference
On July 28, 2024, the 2024 Liaocheng "Belt and Road" International Exchange Conference and the Unveiling Ceremony of the Central Asia International High-end Talent Joint Training Base were held in the Liaocheng High-tech Zone University Science and Technology Park. Professor Tursunbayev Zaporotot, President of Osh Technological University of the Kyrgyz Republic and corresponding academician of the Kyrgyz Academy of Engineering, and Academician Smaylor Erta of the Kyrgyz Academy of Engineering and the Russian Academy of Natural Sciences, among other experts and scholars from "Belt and Road" countries, participated in the event. Liaocheng Deputy Mayor Wang Gang and Zhang Ya, Party Secretary and Director of the Management Committee of the High-tech Zone, attended the event and delivered speeches.
This training event not only provided a valuable learning opportunity for company managers and key personnel, but also built a platform for communication and sharing. During the training, everyone actively interacted and discussed enthusiastically, exploring effective ways to improve management capabilities together. Through this training, everyone has gained rich knowledge and skills, but more importantly, it has inspired confidence and motivation for the future.
How to use a five-axis machining center efficiently? Today, let's learn a few practical steps!
When using a five-axis machining center, the equipment must first be adjusted to ensure that the workpiece and fixture dimensions precisely match, and that the zero points of each axis are accurately adjusted.
Why do composite materials require 5-axis CNC machining?
Composite materials are widely used in various fields such as aerospace, automotive, construction, energy, energy storage, infrastructure, marine, pipelines and tanks, sports and entertainment, and transportation due to their light weight, high fatigue resistance, and strong fracture resistance. Among them, aerospace and automotive industries are the largest application markets for composite materials. Five-axis CNC plays an important role in the processing of composite materials. Why do composite materials need to be processed using five-axis CNC?
Dual-station five-axis machines offer several significant advantages. First, while one station is being machined, the other can be used for material loading and unloading, ensuring continuous, non-stop machining and significantly improving production efficiency. Second, the dual-station design makes operation more convenient and reduces waiting time. However, dual-station five-axis machines typically cost more than single-station machines and may require more operating and maintenance space.
