Electrochemical cutting (ECC) combines electrochemical erosion and grinding to produce a burr-free, shiny surface to a tight tolerance of ±0.005” (0.127 mm).

Pure tungsten simply cannot be made into a tube, aside from gun drilling final sizes — and that assumes the part has a favorable length to ID ratio. It also assumes the customer has lots of money and doesn’t want a lot of these painstakingly produced parts.

Finding a supplier who can deliver quality and on-time service can be tough, especially when it comes to the medical device and other heavily regulated industries. This guide makes it simple.

Metal Cutting specializes in methods that are very effective for cutting pure tungsten, but interestingly, those same methods are not useful when trying to cut tungsten carbide. For example, a customer may tell us they have or want a tungsten tube, but upon further investigation we may find out they actually have or need tungsten carbide in the form of a tube.

While honing and lapping are both used to fine-tune the finish and dimensions of metal parts, the two processes differ in where and how they achieve results.

Tungsten carbide is famous for its wear resistance; in fact, it can only be cut using diamond tools. But while tungsten carbide does have a lot of tungsten in it, the common practice of adding cobalt as a binder makes it a cemented carbide and gives tungsten carbide properties that are very different from those of pure tungsten.

Round Diamond Burs. I personally like the round one because it is easier to do faux calligraphy especially on a curved surface. I use 2mm for glass, 1mm for metal and 0.4mm for compact mirror. I get my burs from Amazon. When you buy the burs from Amazon, make sure you check the shank diameter. My Mystisa 2 drill handpiece can fit 3/32” shank diameter. Some other drills like the Thumb portable drill can fit 1/8” diameter, which has a bigger hole. If your drill has a bigger hole, you may need a collet reducer (or sleeve) to fit 3/32” shank diameter bur or even 1/16” shank diameter burs. The collet reducers are also manufactured for the specific brand, so it may not work for every drill. Ask the manufacturers to make sure.

Drafting tools. I’m not ashamed that I always draft before I engrave. Most products I engrave are very expensive so there is no room for mistakes. I use 3 different ones:

Rub ‘n Buff. You can get this cheaper from any art store like Aboveground Art. A small amount goes a long way. I have been engraving for 2 years and I am still on my first tube. Apply Rub ‘n Buff on the engraved area using a cotton bud and wipe off the excess using cotton pad or paper towel. you have to wipe off the excess quickly though. If it dries out, add more Rub ‘n Buff then wipe fast. Use Rub ‘n Buff for surfaces like glass and plastic (non-frosted only).

Interestingly, in the process of hot swaging and hot drawing the tungsten wire, the alumina and silica would out-gas and the potassium would remain. This element gave the wire non-sag properties under white-hot temperatures.

But ironically, tungsten is NOT used as the name of the element in Sweden or the other Nordic countries. There, as well as in most Germanic and Slavic languages, they use the name wolfram or volfram.
