BIG Angle Heads - Aerospace Machining Case Study
In aerospace machining, it's common to encounter the machining of internal walls in small-diameter holes. The most primitive method is to use a mold for punching, which is not only inefficient but also offers no precision guarantee, and easily leads to missed machining causing significant losses. As competition becomes increasingly fierce, naturally, the requirements for hole machining accuracy and quality have also become higher. Consequently, everyone has started to use angle heads for machining. However, whether using vertical machining centers, horizontal machining centers, or mill-turn centers, because the hole diameter is small and the machining area requires a 90-degree turn, the tool cannot reach inside or be seen. The bottom wall dimensions of the part are very small, making interference highly likely. Therefore, machining the inner side of small holes has always been a challenging problem. Next, let's share an application case of BIG angle heads in the aerospace field:
● Machined Product
Wing sidewall machining of an aerospace component
● Workpiece Machining Difficulties
1. Hole Tolerance
Ensure the 4mm hole maintains a tolerance within 0.05mm.
2. Interference Issues
Solve the interference problems with the bottom wall and the side wall.
● Solution
1. Avoids Bottom Wall Interference
The dimension from the tool center of the angle head to its top surface avoids interference with the 8.5mm bottom wall.
2. Avoids Side Wall Interference
The compact width of the angle head avoids interference with the 15mm side wall.
Micro Angle Head Selection Guide
When selecting a micro angle head, the tool's interference range must be considered. Under conditions that satisfy the machining requirements, try to increase the diameter of the overhang portion while reducing the overhang length to improve the rigidity of the angle head. Below, we can refer to the selection and use of micro angle heads for different scenarios:
Conclusion
The high demands and standards of the aerospace field test the precision and reliability of manufacturing tooling systems. We believe this series of angle heads can meet the requirements of the vast majority of customers and successfully complete the machining. Furthermore, we can also provide suitable process solutions based on customer needs to solve problems encountered in production and manufacturing.
