Machining holes in stainless steel pipe requires precision, stability, and repeatability, especially when working around a cylindrical surface. In this demo, the FlexCNC C-20-02 showcases its ability to efficiently perform hole milling operations on 304 stainless steel pipe using a 4th-axis rotary setup.
Efficient Hole Milling with 4th-Axis Control
This application highlights the use of a 4th-axis rotary to index pipe for accurate hole placement around the diameter. By combining rotary positioning with circular interpolation, the FlexCNC C-20-02 produces consistent, repeatable holes without the need for complex setups or secondary operations.
Instead of traditional drilling, this process uses interpolation to mill the holes, giving operators greater control over hole size, finish, and overall tool performance.
Tooling That Delivers Performance
The operation is performed using a Kennametal Ø1/2″ Harvi I TE end mill, a high-performance tool designed for efficient material removal and long tool life. This tooling enables stable cutting conditions while maintaining precision throughout the operation, especially important when working with stainless steel.
Machining 304 Stainless Steel with Confidence
This demo focuses on:
- 6” 304 stainless steel pipe
- 8″ 304 stainless steel pipe
304 stainless steel is widely used across industries, but it can be challenging to machine due to its tendency to work harden and retain heat. The FlexCNC C-20-02 handles these challenges with ease, delivering smooth, controlled cutting and consistent positioning throughout the process.
Why Circular Interpolation Matters
Using circular interpolation for hole milling provides several advantages over traditional drilling:
- Greater accuracy and hole size control
- Improved surface finish
- Reduced tool wear
- Flexibility to adjust hole diameters without changing tools
When combined with a 4th axis, this approach allows for efficient machining of multiple features around the pipe in a single setup.
Built for Real-World Applications
This demo highlights a practical machining solution for shops working with stainless steel pipe. The ability to reliably process 304 stainless while maintaining precision and repeatability is critical for both fabrication and machining environments.
The FlexCNC C-20-02 delivers a solution that helps reduce setup time, improve consistency, and increase overall efficiency on pipe machining applications.
