Creating the Ideal Edge Break with Xebec Tools in CNC Machining
When designing or refining a CNC machining process for a new part, machine process engineers and application development teams must give deliberate attention to edge breaking. The right edge break is more than just an aesthetic finish—it’s critical to the safety, function, and longevity of components, particularly in high-performance industries such as aerospace, medical device manufacturing, and automotive. Xebec deburring and surface finishing tools make it possible to achieve consistent, reliable edge breaks directly on your CNC machine, helping you maximize both productivity and quality.
Why Edge Breaks Matter
A properly executed edge break ensures that sharp edges do not compromise the part’s integrity, safety, or assembly compatibility. Poorly considered edge conditions can result in stress concentrations, premature wear, or even failure in mission-critical components. For instance, in the aerospace industry, a burr left on a machined hole edge can lead to fatigue cracking or fluid leakage.
Common types of edge breaks include:
- Chamfers
- Radius (R) edges
- Controlled edge breaks
- Deburred (sharp but safe)
Each has its application depending on the material, function, and compliance standards of the part. Learn more about edge break standards and terminology.
How to Decide on the Ideal Edge Break
The correct edge break depends on:
- Material characteristics (e.g., titanium vs. aluminum vs. carbon fiber)
- Functional purpose (e.g., sealing, fitting, load-bearing)
- Regulatory and industry standards (e.g., NAS, ASME, ISO)
- Part geometry and tolerance zones
- End-use environment (thermal, corrosive, high-pressure, etc.)
Our application specialists often recommend referring to proven use cases when selecting your edge break strategy. For example, this application example on aluminum aerospace fittings illustrates how a Xebec Brush Surface can provide consistent edge radius control with minimal operator involvement.
Why Xebec Tools are the Superior Choice for Edge Breaks
Xebec tools are made from a proprietary ceramic fiber material that maintains consistent cutting performance over time, making them ideal for in-machine edge finishing. Unlike abrasive nylon brushes or manual deburring, Xebec brushes provide:
- Precise control over edge break size
- Repeatability across multiple parts
- Integration directly on CNC machines or robots
Learn how Xebec tools outperform traditional abrasives.
Selecting the Right Xebec Brush for Your Process
- Xebec Brush Surface
- Ideal for consistent edge breaking across a flat or contoured surface
- Suitable for aluminum, steel, and stainless
- Compatible with simultaneous surface polishing
- Xebec Brush Crosshole
- Perfect for internal intersections and hard-to-reach crossholes
- Commonly used in hydraulic, medical, and fuel system components
- Xebec Brush End Type
- For targeted deburring and polishing of small or complex features
- Xebec Stone Flexible Shaft
- Best for high-precision edge breaking or chamfering of intricate shapes
Each brush type is compatible with CNC integration, allowing you to program edge break, finish, and polish in a single machine cycle.
Maximizing Automation and Repeatability
By pairing a Xebec brush with a Xebec Floating Holder, you achieve adaptive pressure control that ensures even edge breaking despite part or fixture variance. Add a Self-Adjusting Sleeve to the process to fully automate the tool path, pressure, and compensation for wear.
This setup enables a true lights-out manufacturing process—minimizing downtime, maximizing tool life, and ensuring consistent quality across shifts and production runs. For an inside look at how this works in practice, check out our blog post on fully automated deburring cells.
Improving Efficiency and Quality in a Single Machine Cycle
With Xebec tools, you can:
- Eliminate secondary deburring operations
- Reduce part handling and re-fixturing
- Shorten cycle times
- Increase part consistency and accuracy
This integrated approach is explored in detail in our article on how Xebec saves time and money in CNC deburring.
