Tim, also thanks for your suggestion. The guillotine idea sounds interesting, but since I want to do curved lines and I am not working with sheet metal, I wonder if that would work. All ideas are worth investing though, so thanks.

Abrasive diamond saws are typically a poor choice for cutting metal due to slow metal removal rates but it will work. Titanium and its alloys can typically be cut with standard metal working tools (like a jewelers saw). They wear out the cutting edges faster many than typical jewelry metals but as long as the tools are kept well lubricated and sharp they will cut titanium much faster and more cheaply than diamond abrasives.

However, there are also some disadvantages to using fine thread fasteners. One is their susceptibility to stripping. Because the threads are smaller and shallower, they are more prone to damage when subjected to heavy loads or vibrations. Fine thread fasteners also require more turns to achieve the same level of tightness as coarse thread fasteners, which can be time-consuming and cumbersome.

I use a lot of sculptural rainbow titanium in my work and sometimes I get these massive pieces that I need to cut into smaller pieces which could be done with a diamond saw blade. I inherited a band saw for cutting stained glass which has a diamond blade, and so I was wonder if I could use it to cut the titanium without ruining it. I have no intention on using it for glass, so that is not an issue. Your input would be so appreciated.

Coarsethread vs fine thread

On 1/4 to 1/2 " material a standard band saw with a bi-metal or cobalt steel blade with something between 10 and 14 teeth per inch will will work fine. You will want a coolant pump and a soluble oil and water based lubricant like Rel-Saw semi-synthetic coolant to keep the cutting area and blade cool. You would need similar coolant for a diamond blade as well. I think you will find that the band saw will cut much faster than the diamond abrasive saw.

The larger root diameters and greater cross-sectional area resist corrosion. Even the debris does not clog the spacing between the fastener threads. These factors make them fit for outdoor and marine applications.

I did however try the diamond blade which worked fine. It was hard to tell if it was slower than other blades since I have no comparison, but it seemed to go fairly quickly. My biggest challenge now is fitting the titanium under the clearance of the blade guides and the guiding plate. If anyone is interested in seeing the type of titanium I am working with stop by my site. It’s really different, very sparkly and fun to work with.

The saw is a Diamond Laser 1000S. The existing blade is definitely used and I might need another one soon if not now. I guess I can get a new one from the company that makes the machine if I can find them – dealing with the machine itself will be trial and error Thanks for the link to the additive!!

As a data point, I’ve been cutting titanium with standard High Speed Steel endmills with great result, machining out shapes from sheet stock. An old machinist friend feels that people fear working with titanium, when it isn’t that difficult in practice. So I’d just use a jewelers saw, or shear to cut your sheet.

Fine threads have a smaller pitch, which means there is less space between each thread. Fine thread fasteners are ideal for thin and delicate materials. They are mostly employed in electronics and aerospace industries, where weight and space considerations are critical.

When I say a massive piece of titanium, I’m not talking sheet metal, I’m talking about sculptural free formed rainbow titanium. Commercially, you probably have not seen it before, but I have some pictures on my site. Most pieces are small, but some pieces are not “jeweler” sized and they can be anywhere from a 1/4" thick to an 1" thick and that is why I want to cut it more easily.

Fine thread fasteners are better suited for delicate materials or applications involving weight and space issues. They are also more precise and easier to install in tight spaces.

One of the primary advantages of fine thread fasteners is their ability to provide a tight and secure connection without damaging the material. Because the threads are smaller and closer together, they can provide a more even force distribution, reducing the risk of cracking or deformation. Fine thread fasteners are also more precise and can provide higher accuracy levels when tightening.

I also did some digging and found out the “best” way to cut it is using a carbide tipped saw for metal (not wood). This advise was given to me by people that deal with Ti all the time and cut the sculptural crystalline, metallic, and satin-matte titanium that I use.

One of the primary advantages of coarse threads is their ability to create a strong and secure connection. Because the threads are deeper and wider, they can provide a better grip and resist loosening over time. Coarse thread fasteners are also easier to install as they require fewer turns to achieve the same level of tightness as fine thread fasteners.

Hey, I have been on vacation and not following this thread, but I looked on your web site at the piece you pictured. That is definitively “splash”. It is found on the floor in titanium mills. It is heavily oxygenated, brittle and hard. I have a piece somewhere. Do you have a regular source for it? I guess I would go at it with stone cutting tools. They are cheap and readily available. You might find a lapidary shop to give it a try. Bill

In conclusion, both coarse thread and fine thread fasteners have their advantages and disadvantages. The key is to choose the right fastener for the application, and Bhavya Industries can help you with that. Whether it’s a coarse thread or fine thread, selecting the suitable fastener can ensure a strong and secure connection that will stand the test of time.

Titanium is tough to cut but not all that hard, even aerospace grades like 21S or Al6V4 are just not hard enough to need diamond tools. It is nowhere near as difficult to cut as most tool steels or nickel alloys. I would much rather cut titanium than even most stainless steels. The bigest problem is keeping the blade and work cool as titanium is a very poor thermal conductor and the heat from cutting is not carried away from the cut by the bulk metal. This overheats the cutting tool and causes it to lose its temper and it ceases to cut.

However, there are also some disadvantages to using coarse thread fasteners. One is that they can damage the material being fastened. The larger threads can create larger holes in the material, which weakens its structural integrity. Industries do not often use coarse thread fasteners and thus, making them hard to find and expensive.

Coarse threads’ nuts and bolts have a larger pitch, creating more space between each thread. Owing to the enhanced ability to bite into the material, the threads increase the fastener’s holding power. Coarse threads are applicable where the fastener has to endure heavy loads or vibrations, like in construction. Bhavya Industries has been fulfilling the need for a fastener for the construction industry for many decades now.

The fine threads allow for finer adjustments and tighter tolerances, allowing them to tighten the fastener to the required precision level.

Another advantage of coarse thread fasteners is their ability to resist stripping. Stripping occurs when the threads on a fastener become worn or damaged, making it difficult to tighten or loosen. Because coarse threads are deeper and wider, they are less likely to strip than fine threads.

Pros and consof coarseand fine thread

The answer depends on the application. Coarse thread fasteners are better suited for heavy-duty applications where strength and durability are critical. They are also more suitable for materials that can withstand the larger holes created by larger threads.

Another advantage of fine thread fasteners is their availability. Fine thread fasteners are more commonly available in different sizes and materials, making them more accessible and affordable.

Fine thread vscoarsethread strength

I have cut up a lot of thin,less than 1mm,titanium sheet in my time. It does shear very well, in fact I bought a guillotine when the engineering firm I used to go to damaged the blades on their big guillotine. So find a company with one and ask to use it. On the same subject I saw a company in the UK yesterday who laser cut shapes out of titanium sheet. You can get very fine details done and not too expensive for a moderate quantity.

I was using a modified bandsaw to cut other materials-- my supply off narrow fine blades dried up so I searched all over I finally found some in Switzerland :

When it comes to fastening materials together, the choice of thread impacts the effectiveness and durability of the joint. Two common thread types used in fasteners are coarse and fine threads. While both have unequivocal advantages and disadvantages, the question remains: which is the better fastener – coarse thread or fine thread? Let’s take a closer look.

As far as the saw goes, I was told diamond abrasives were the best because of the hardness and the thickness (1/4 to 1/2" thick), but maybe a jeweler’s saw would be worth a try. What kind of lubrication are you using for a regular saw? Does anyone have any suggestions on a jeweler’s band saw blade manufacturer that may have a blade to fit the machine I have?
