Electron Beam Drilling

What Is Electron Beam Drilling?
Electron Beam Drilling is an innovative machining process, which drills many small holes in resistant material. This process is the best solution in specific cases. The perforation technique is simple: The highly concentrated energized electron beam instantly vaporizes the material at the point of impact. In just a few thousandths of a second, the beam forms a fine channel through the work piece.

As a machining process, Electron Beam Machining (EBM) is often mentioned along with Laser Beam Machining (LBM), Electrical Discharge Machining (EDM) and Electro Chemical Machining (ECM). These nontraditional techniques are used when the requirements exceed mechanical machining and drilling capabilities or when they have overriding cost advantages. Compared to other hole drilling techniques, the electron beam process has unique features that give it special capabilities for hole drilling over a wide range of applications. With drill speeds up to 2000 holes per second, this technology is far ahead of its competitors. In response to recent industry demands for smaller hole diameters, Acceleron continues to develop NEW processes and tools. We currently drill holes as small as 0.002" - 0.004" in small tubes down to 1/2" diameter.

Advantages of Electron Beam Drilling
Process is a noncontact thermal "tool"
High power density is focused into a small spot
Critical beam parameters can be adjusted electronically at high speed
Can produce inclined holes at various angles to the surface
Drills on a continuously moving target to maximize drill speed
Provides a drilling rate up to 2,000 holes per second in thin sheet metal
Can drill material thicknesses from 0.002" to 0.200"
Drills holes from 0.002" to 0.040" in diameter
Is capable of an aspect ratio (depth to diameter) of 25 to 1
Hole profiles can be taper, cylinder or bell
