Photo chemical machining

Photo  chemical machining is used to produce components for many types of aerospace applications from airframe stiffeners and heat sinks to satellite batteries.

The ability to produce complex parts that are free of burrs and distortion in very thin gauges of metal is a key advantage of photochemical etching.

Many aerospace components are produced in aluminum to save weight.  Photo etching aluminum is challenging because it is a very reactive metal that readily oxidizes.  (Aluminum hydroxide is a component of solid rocket fuel!)

Richard Huttinger, a metallurgist, developed a proprietary method for precision chemical milling of aluminum for jet engine components. 

JULID ''s ability to photo etch aluminum up to .080" thick continues to find new applications in many industries.

Photo chemical machining is exempt from NADCAP because the process does not alter any of the properties of the metal.



Photo   chemical etching is an ideal process for metal grids, screens, meshes, filters, separators, microfilters, grilles, lighting diffusers and other perforated metal applications.

The photo etching process produces consistent, burr-free holes as small as .004” in .002” thick material. As a general rule, minimum hole size is 110% of the thickness of the material, e.g. on .010” material, the smallest hole would be .011.”

Unlike mechanical perforating methods such as punching, stamping or laser cutting, photochemical machining of metal leaves the material free of burrs and induced mechanical or thermal stress or deformation.
