Deburring of cross holes

Deburring cross holes (also called "intersecting holes") is indeed a significant challenge. Depending on the diameter ratio of the two intersecting holes, the burr formation can vary slightly or be very uneven. Especially when the axes of the two holes do not intersect at a right angle, due to the pattern of burr formation, the burr root will appear at different heights.
Therefore, the angle between the main hole and the intersecting hole has an important impact on the chosen deburring tool for the intersecting hole and the final machining effect. This requires the use of cleverly designed tools with special geometric structures that can achieve perfect machining results and reduce the need for repeated adjustments. This includes a type of system that can deburr each intersecting hole sequentially as the tool passes through the main hole.
Even for deburring small cross-holes (especially in high-volume production), a reliable and time-saving production process is crucial for your competitive advantage. The most effective method here is to deburr directly on the machine tool. This means the workpiece is completely deburred when it is removed from the machine tool. You can achieve repeatable machining results at lower process costs and reallocate resources originally intended for subsequent deburring operations to other areas.

There are two methods for deburring cross-holes:
1. Machining through the cross hole
2. Machining through the main hole
For both deburring methods, we offer suitable cross-hole deburring tools:

1. Machining through cross holes

Deburring is typically performed through cross-holes because this usually provides smoother access to the burrs. Cross-holes are often shorter, making it easier for the tool to be inserted. Since cross-holes are also usually drilled after the main hole, accessibility using a deburring tool through the cross-hole is guaranteed in this process setup. Furthermore, it is crucial to consider which burrs are more critical in subsequent steps (e.g., for the functionality of the component). If the more critical burrs are located within the cross-hole, then deburring of that hole should be prioritized.

2. Machining through the main hole
If deburring is required for the openings of multiple intersecting holes, it is often more efficient to machine them all at once through the main hole. The main hole offers better accessibility, which is a decisive factor in choosing this machining method. Furthermore, it is equally important to consider which burrs on the part are more critical in subsequent steps. If the more critical burrs are located inside the main hole, then deburring this hole should be prioritized.

Application Cases from Practice

Deburring of intersecting holes

Workpiece: 11SMn30+C steel, hydraulic components

Tool: HSD (High-Speed Deburring) deburring tool

"For quality reasons, even small batches of hydraulic components should be completely deburred using machine tools. The design feature of HSD tools is that the cutting edge remains retracted when the cooling medium is not under pressure, and only expands when pressure is applied at the required position, removing burrs with a 'pulsating' action. Depending on the material, even large burrs with a root thickness exceeding 0.2 mm, or those with attached flanges or drill caps, can be reliably removed.                                                     Despite different hole diameters, an HSD tool with a diameter of 11.30 mm can also be used to deburr cross holes produced on other parts. For hole diameters greater than 4 inches standard size, the same HSD tool can reliably remove burrs by traversing the deburring area in a circular spiral motion."
