Question #: 136

Question: Can stainless steel rust? Why?

Current Solution

Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface. If the iron is embedded in the surface, you can try a solution of 10% nitric and 2% hydrofluoric acid at room temperature or slightly heated. Wash area well with lots and lots of water after use. Commercially available "pickling paste" can also be used.

  • I know you cant cut it but can you etch stainless steel with the laser?

    No you cannot sketch any kind of metal unless its coated from the molecular level or having it coated individually. However there are some types of coatings (Thermark and Cermark) that you can use to coat the steel so that you will be able to use our laser machine to sketch any metal.

  • Is stainless steel magnetic?

    There are several "types" of stainless steel. The 300 series (which contains nickel) is NOT magnetic. The 400 series (which just contains chromium and no nickel) ARE magnetic.

  • What makes stainless steel stainless?

    Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material. See the "Stainless Steel Primer" for more information.

  • Can I attach a 400w CO2 laser tube to you units (for cutting Stainless Steel at 1/8") ?

    A 400w laser tube will not be a simple swap of our laser tube in our blackTooth or our spindle/laser hybrid. The overall size factor of a 80w - 400w is greatly larger than our 40w laser tube and will be the biggest issue. You will have to completely modify our units to retrofit a larger tube, which might be more costly than expected as well as more time consuming.

  • What is the difference between 18/8 and 18/10 stainless steel?

    The first number is the amount of chromium that is contained in the stainless, i.e., 18 is 18% chromium. The second number is the amount of nickel, i.e., 8 stands for 8% nickel. So 18/8 means that this stainless steel contains 18% chromium and 8% nickel. 18/10 is 18% chromium and 10% nickel. The higher the numbers the more corrosion resistant the material. 18/0 is a misleading designation. Both 18/8 and 18/10 contain nickel and are part of the grade family "300 series" stainless. 18/0 means that there is 18% chromium but zero nickel. When there is no nickel the stainless grade family is the "400 series". 400 series are not as corrosion resistant as the 300 series and are magnetic, where the 300 series are non-magnetic.

  • What is the difference between 18/8 and 18/10 stainless steel?

    304 contains 18% chromium and 8% nickel. 316 contains 16% chromium, 10% nickel and 2% molybdenum. The "moly" is added to help resist corrosion to chlorides (like sea water and de-icing salts)

  • Why is my motor loosing steps

    Sometimes the problem is just too much dust on the motors. Wood dust and grease can get pretty sticky over time. This is especially bad with lead screws as the dirt is collected inside the nut. Just clean the motors and guides, put some petrol on them to get rid of old, sticky oil, clean again and relube.

    I would look for worn bearings (or perhaps mounting bolts, or even a loose set screw on the motor couplings). You might even go to the extreme, of removing the motor coupling from the drive, and try turning the drive by hand. If you can't, then you have some type of binding issues in the mechanical drive on that axis. Again, look for worn bearings, etc. I once had this issue to appear on my Y axis, and discovered that it had been dragging a shattered bearing around (instead of it smoothly rolling along, as it was designed to do).

    This could also be caused be a loose sprocket appearing like the motor is loosing steps.

  • HOW DEEP CAN CUT IN ONE PASS?

    If you use the 2.2kW spindle, it can cut at 3/4 inch or 19 mm deep with at least a 1/4" cutting diameter single flute end mill. You will get better results with larger diameter end mills, but that is the worst case scenario. I still recommend doing a finishing pass on the edge to make sure everything is perfect.

  • WHY SHOULD I BUY THE SPINDLE?

    The spindle is quieter and has more consistent torque (It doesn't get "bogged down" when it starts cutting into material). It can be used with collets of varying sizes (not restricted to imperial sizes). It is water cooled and so it does not blow air downward to cool the spindle like the router does. The spindle is also machined with much higher precision than typical routers and will have a much longer life.

  • HOW CAN COOL THE LASER TUBE?

    Cooling is not as tricky as you might think. There is 3 ways to approach this, only 2 really matter for a low scale 40w setup. First one is the cheapest and easiest. The higher the temp of water the worse your performance will be, from what I understand anything in the 30C range is about the most tolerable it gets. Lower is better. But not frozen...from what I've been told a very experienced cutter, he found 8C was the highest power he achieved.

    1. Use a 5 Gallon resovoir system which gives you a fairly large space of water to heat up before you need to tend to it. Add about a cup of anti-freeze to the mix of DISTILLED water. You don't want ANY minerals in the water that might build up in your system. The anti-freeze works to keep algae and other ickies from growing in your water.

    2. Use a smaller resovoir system (or even closed loop) and install 1 or more radiators found in CPU cooling systems with 120mm fans attached. This will continously cool your water system to ambient room temperatures, but with a tiny resovoir it will be difficult to add things like ice-packs to drop the temps if the ambient is quite hot.

    3. Using an industrial coolant system. Overkill and unless your cutting A LOT, this is a very expensive option to take. You can also explore the idea of Peltier cooling but it is extremely expensive electricity/BTU wise compared to an industrial cooler.

  • can i use or by my own spindle

    Yes, absolutely. If you have your own spindle and you wish to purchase a machine, let us know the diameter of the spindle so we can create the proper mounts. If the spindle has a different mounting configuration, we can also create the mount using your specifications.
