Part thickness ranges from 0.0005 to 0.062 in. Can machine part sizes up to 30 x 20 in. Prototype and low to high volume production runs.
· In the aerospace industry, chemical milling is the process of using a strong acid or base solution (etchant) to dissolve unwanted aluminum, titanium, steel, etc., …
Chemical milling is the subtractive machining process using baths of temperature-regulated etching chemicals to remove material for producing the required shape. It is defined as the method of chemically corroding of material to produce blind features like pockets, channels, etc.
Chemical Milling and Maskants Our solutions simplify masking. First, they can be applied in many ways: by dip, spray, flow-coat or brush. Second, they save working hours as air-dry is sufficient for many of these applications.
Providing the Aerospace, Medical, Military and Commercial markets with precision chemical milling on fabricated components since 1988, Tech Met specializes in complex and precise chemical milling for build to print and custom projects on a wide variety of materials.
Milling (also known as chemical or photochemical machining) is a chemical process to remove precise amounts of material from aircraft components. During the process, a metal surface is partially masked in a chemical solution and then submerged in etching chemicals. The unwanted material dissolves, and the desired shape remains.
Chemical milling, also known as chemical etching, is so precise it allows for the creation of parts ranging in size from 0.0005” to 0.060” with superlative accuracy. Additionally, manufacturing micro-precision parts using chemical etching utilizes tooling created with CAD in just hours, as opposed to days, weeks, or months like more .
This article discusses the principal process steps, specifications, defects, applications, advantages, and disadvantages of chemical milling (CM) in aerospace industries. The process steps include precleaning, masking, scribing, etching, final cleaning, stripping, and mechanical finishing.
Chemical milling services for aerospace components. Copper, silver, gold and various other metals worked. Capable of milling parts with possible length up to 30 in. and possible width up to 30 in. Various capabilities include engineering, fabrication, assembly, programming, sourcing, coating, contract manufacturing, designing, drilling, testing .
Chemical milling process has applications in semiconductor fabrication industries and the printed circuit board. This process is also utilized in the aerospace industry to eliminate the shallow layers of material from missile skin panels, large aircraft components and extruded parts for airframes.
Milling. Latour Aerospace utilizes the latest chemical milling technologies to produce high-quality parts for top industry providers. As an alternative to mechanical operations like CNC, chemical milling is a cost-effective and highly controlled method to reduce the weight of airplane parts.
· Chemical milling, the removal of metal by chemical attack of alkaline or acid solution is routine for specialized reductions in thickness. For complex large surface areas in which uniform metal removal is required, chemical milling is often the most economical method. . The process is used extensively to etch preformed aerospace parts to .
Capable of processing parts up to 48 feet in length, Spirit can manufacture a wide range of finished products — from machined fittings to large fuselage skin panels. Anodizing, chemical milling, cleaning, coating, penetrant processing, plating and surface preparation can be accomplished on a wide variety and size of parts.
Chemical milling is a process that is popular among design and manufacturing engineers from the aerospace, automobile, and electronics industry. This process is a metal alteration process. It uses chemical etchants to erode pre-determined areas of metal sheets and parts.

Standard Practice for Liquid Penetrant Examination. GP17G. Procedure, Etching prior to Penetrant Inspection. GSS 26100. Chemical Milling of Aluminum Alloys. GSS 26300. Chemical Milling of .
What is Chemical Etching? Thin Metal Parts Chemical etching, also known as chem etch or chemical milling, is one of the quickest, most cost-effective, and adaptable metal fabrication processes available for the creation of precision metal parts. It offers a high-quality, low-cost solution for creating custom thin metal pieces made to exact specifications.
Chemical Milling / Chemical Etching. At Photofab, we’ve been working in chemical etching (otherwise known as chemical milling or photo etching) since 1968. In that time, we’ve built a large pool of technical knowledge on the subject; we know the benefits it brings to our customers.
All 3 locations have the required customer approvals and are NADCAP certified. Our Tulsa, Oklahoma, facility is 175,000 sq. ft. with more than 130 employees dedicated to metal finishing and chemical milling. Our finishing capacities will support products up to 15 ft. with chemical milling up to 30 ft.
· Chem milling operations on aluminum or titanium typically employ masking to achieve selective dimensional changes and specific shapes. Aerospace finishing often requires a part be held in place with an in-house custom produced jig or fixture which requires protection from chemical solutions via masking materials.
