I recently ground a sharp point tool and 3D printed a holder for it. But it only cut one way. I had to cut some very fine but precise grooves in acrylic. I couldn't maintain the tolerances due to variations in material thickness. I ordered one of these earlier today due to watching a few of these vids. I really enjoyed yours. Thanks. Jim

The good thing about these spring loaded tips is that you don't really need to deck off your surface before engraving. There's plenty of travel in the spring to take up minute variations in height.

I know that this video is several years old but for anyone just starting to use a spring loaded drag bit you need to know that the spring pressure is not linear. The early part of the spring compression has a very steep pressure change curve. The first .300" of compression is on that steep part of the curve and is too light. It would change pressure too rapidly with surface height variations. After compressing to only 0.050" (1.27mm) as in this video you only get 9.5 oz of pressure which is only 34% of the available spring pressure. You need to compress the spring to over .300" (7.5mm) to get into the linear part of the tool's pressure curve, then it goes up very linearly all the way up to .590" (15mm). When at max compression at 15mm it goes up to 31 oz of pressure (in my measurements with my tool) This won't make much difference for very flat surfaces except to make it engrave too lightly but on uneven surfaces you would want a much flatter pressure curve to keep the engraving looking the same throughout. I compress my drag bit to 7.5mm (.295") to be in the center of the usable range. That way if the surface goes lower or higher the engraving depth will stay consistent.

Have you tried running the spindle while the tool is engraving?, ...so that is half scratching half milling. Great video. I am looking into engraving these days, but I am kind of worried about getting trapped into spending a lot of money on diamond-tipped bits. Plus yours is spring loaded so that is another problem. I see Dremel 9929 bits, but it is without the spring. With the excellent auto level system in my NewRAD CNC controller, I don't think that I need the spring, but I don't think a diamond tipped bit could do the auto level probing procedure. But that would not be a problem. I could just use a regular Dremel 9924 bit to do that part, and then switch to the diamond tip after I had the height map. I think that I have tried engraving before with a 9924, and it did not work out too well. I can't remember, but I am about to try it again. But it looks like that you need a diamond tipped bit to do it well. Your final real engraving in the video looked awesome.

It depends on how much it is, how worn it is, and whether it is old enough to be made in the USA, or if it's Chinese/Taiwanese produced since Grizzly bought South Bend. I typed in "South Ben 2VH," and found a ton of information on it. Spare parts, forums, manuals (on Vintage Machinery among others), and ones for sale to see if the price on the one you're looking at is reasonable.

@Clough42
@Clough42 5 жыл бұрын
It can be done inexpensively or you can spend as much as you want. It can be done for the cost of the mill plus about $1000 (US) assuming you already have a computer and sfotware and you have other machines you can use to make all of the brackets and mounts. That assumes cheap eBay components and a lot of work making parts. I started that way, but struggled with various issues and upgraded a bunch of components (DSP-based drivers, a big linear power supply and a SmoothStepper motion controller). If I were starting over from scratch, I'd expect to spend $1500 or $2000, depending on what I already had on hand (cable, connectors, etc.)

Adding anodizing to the equation makes things a little unpredictable from my experience. I do a lot of diamond engraving on black anodized hammond enclosures and once in a blue moon I'll get a batch of enclosure where the text looks fuzzy. Switch to a new anodized plate with no machine changes and everything looks great. The only explanation I can come up with is the hardness of the surface. On a similar note I have not had any success engraving painted surfaces.

Aluminum is really the only metal that needs coolant or oil when being machined, besides super alloys. People think machining aluminium is easy because it's the soft, but it's actually one of the most difficult. (Again, besides super alloys.) It's gummy and is prone to chip welding.
