Chemical machining and milling introduction chemical machining (cm) is the controlled dissolution of workpiece material (etching) by means of a strong chemical reagent (etchant) in cm material is removed from selected areas thin sheets photochemical machining (pcm) for etching by using of photosensitive resists in. The photochemical machining (pcm) process lends itself to designs of low to medium volumes of metal parts from very basic designs to those which are intricate, thin and difficult to handle in most cases, “if it can be drawn, it can be etched,” is considered the extent of the process’ design capabilities. Precision machining services such as photochemical etching for electronic components and parts capabilities include conventional discreet and continuous reel-to-reel etching and low-cost cad tooling generation. Northwest etch specializes in photochemical machining (pcm) to create precision metal parts since 1978, nw etch has worked with companies all over the world to create custom parts to meet their needs.
The processes of using photo chemical machining, photo etching, and chem milling, are ideal for thin metal parts fabrication, fine line etching, and engineering of micro machined parts many of these thin metal parts are then precisely formed into complex shapes. Pcm products provides photo chemical etching, photo chemical machining and photo chemical finishing services in florida. Photochemical machining (pcm) is one of the least well-known non-conventional machining processes the technique is relatively modern and became established as a manufacturing process about fifty years ago.

Photochemical machining (pcm) pcm is an extension of chm that uses a series of photographic and chemical etching techniques to produce components and devices in a wide range of metals, especially stainless steel. Abstract the present work is focused on estimating the optimal machining parameters required for photochemical machining (pcm) of an inconel 718 and effects of these parameters on surface topology. The advantages of photochemical machining (pcm) is that the product will not generate burrs, coining, or unnecessary internal and external stress on virtually any ferrous and non-ferrous metal, without chemical or physical manipulation of the material being manufactured. Photochemical etching (pce), also known as photochemical machining (pcm), is the use of photo-reactive resist to fabricate a metal part based on desired dimensions pce/pcm are similar to printing processes, using a photo tool to print part dimensions onto photo-resist coated metal, which is then developed and etched, resulting in the desired part.
