Deburring drilled holes is essential to the manufacturing process. Burrs that aren’t cleaned up can cause part failure by breaking off and clogging or damaging a part or an assembly or by cutting a wire or an O-ring that’s passed through a bore. But cross-holes, where two or more holes intersect, are hard to reach and often require deburring by hand.
When cross-hole deburring, challenges are commonly encountered in applications with sloped or uneven surfaces, wide penetration angles, multiple intersecting bores, 1-1 ratio cross-bores and microscale bores. The burrs that develop in these situations frequently can’t be easily removed with standard deburring tools on a CNC machine.
