Q:What are the different methods of coil slitting for precision cuts?

Coil slitting, a process utilized for cutting large coils of material into narrower strips, is achieved through various methods that offer distinct advantages and suitability for different applications. 1. Rotary Shear Slitting, the most commonly used method, employs rotating circular knives to shear the material and create multiple strips. The distance between the blades can be adjusted to achieve the desired width. This method guarantees high precision with smooth and burr-free edges. 2. Drag Knife Slitting involves the use of a knife with a drag or tangential orientation that follows the material's contour and produces accurate cuts. It is ideal for materials with irregular shapes and finds application in the textile industry to cut fabrics. 3. Scissor Slitting utilizes two blades that move in a scissor-like motion to cut the coil. This method is commonly employed for thinner materials, providing excellent control and precision. It is ideal for materials prone to deformation or wrinkling. 4. Razor Slitting involves the use of a single or multiple razor blades positioned perpendicular to the material. It is particularly effective for cutting stretchy or delicate materials, minimizing the risk of tearing or deforming. 5. Crush Cutting applies pressure from a hardened steel roller or an anvil against a softer material, causing it to deform and split along the desired cutting line. It is suitable for materials that are challenging to cut with sharp blades, delivering precise and clean cuts. In conclusion, the choice of coil slitting method depends on the material, desired precision, and specific application requirements. Each method offers unique benefits and can be tailored to meet specific cutting needs, ensuring accurate and efficient coil slitting processes.

Q:I felt that my nylon strings don't sound as good as steel ones. Is it okay that I replace them with steel ones, even if my guitar is classical? Thanks.

I think so, I've never played classical, only acoustic and electric but my neighbor has a classical and he has all steel strings on it.

Q:Will a stainless steel mesh screen scratch a titanium cup, or vice versa?I have a titanium french press and am thinking about replacing the included press with an all steel one. I am worried about little flakes of titanium or steel getting ground off into the coffee when the press slides in and out. The original press has a polyester cloth for a screen, so nothing scratches.

Steel is usually harder than titanium, at least when both materials are hear-treated to give their best strengths. And a harder material can scratch a softer one. So I imagine that the answer is that it will scratch. However much of the rest of your question is unclear and it may be that the amount of friction between the two is so small that no wear will take place, so there could be no problem. The function of the polyester cloth may be vital in reducing this friction, so that unless you keep this part of the original design, the scratching will become worse no matter which combination of metals are used.

Q:I want to make a chess set out of stainless steel, but I'm not sure what type of mold I need or where I can go to have the steel melted and molded for me. Any ideas? I live in Southern, NJ.

I'll buy one. You'll have to machine it from blocks... You could invest in a milling machine - they are like drill presses and lathes all together and more... If you hook it up to your computer, you can do a CNC milling, where you can get really creative and finely detailed. Stainless is heavy and hard, so it'll go through your bits, and you should use the super duty bits as well. I have always wanted an SS chess set, I made a board out of leather. It's really super awesome, just need your pieces now. Or make mine from Plutonium, or Tungsten Carbide.

Q:So today I was bored and was reading a shotgun shell box,the box was slug 12ga.I noticed it said not to be used in Damascus steel or twist barrel.It was to my understanding that Damascus steel is very strong and many stories came from what it could cut when used in a blade or sword.The little bit of info that i could find was that Damascus used earlier in the turn of the century on shotguns should not be fired unless special maintenance has been given and check out by gunsmith.So is Damascus not strong like i thought and not be able to handle higher pressure or why the reason for the warning?*

Damascus steel in gunmaking Prior to the early 20th century, all shotgun barrels were forged by heating narrow strips of iron and steel and shaping them around a mandrel.[22][23] This process was referred to as laminating or Damascus and these barrels were found on shotguns that sold for $12.[22][23] These types of barrels earned a reputation for weakness and were never meant to be used with modern smokeless powder, or any kind of moderately powerful explosive.[23] Because of the resemblance to Damascus steel, higher-end barrels were made by Belgian and British gun makers.[22][23] These barrels are proof marked and meant to be used with light pressure loads.[22] Current gun manufacturers such as Caspian Arms make slide assemblies and small parts such as triggers and safeties for Colt M1911 pistols from powdered Swedish steel resulting in a swirling two-toned effect; these parts are often referred to as Stainless Damascus.[24]
