What is more accurate water displacement of a volume or measuring their dimensions and calculating?
That depends on the shape. If it is a uniform configuration with simple sides or walls where accurate dimension are used then calculating the volume is more accurate. If the cavity is of a unusual shape such as the combustion chamber for a cylinder head on an engine, then water displacement is more accurate. With modern software, dimension for such a cavity can be calculated by computer. However, variation to the cavity when machined or cast will never be the same as the computer model. R. Clontz
What does micro-inch finish mean and how is it measured?
micro means 10 to the -6 inches so for example 32 microinches would be 0.000032 inch. With respect to surface finish it is basically a measure of the height of the "peaks and valleys" of the finish of a surface. There are different ways to measure this (RMS, etc.) but that is basically what it means. So for example a 125 microinch finish is a typical machined fnish for metals but a 32 is much better and would be called out where sealing surfaces may be needed.
How was a Rolex submariner ceramic bezel manufactured their ceramic bezel or are made is the numbers and lines on the bezels are painted and if then what kind of paint are they using?
It's not painted, it's gold or platinum, I'm not too sure exactly how the bezel itself is made. I think that first the raw ceramic powder is pressed into a mould at about 300 tonnes, the numerals are machined, the bezel is fired then the whole bezel is plated with either gold or platinum via PVD (Physical Vapor Discharge) the bezel is polished back to leave the polished ceramic and plated numerals. Check out the video on their site, apparently takes 40 hours, possible just marketing bull....
How do you make the wax form for investment casting?
The wax form is either carved manually with hand tools and hot knives, or machined either with CNC or manual machine operations. An alternative if you have a completed model to work from is to coat the item with a rubber or silicone compound and carefully cut it from the model after it has hardened. It can then be used to pour liquid wax into to form the wax model. Generally the first method is used to cast the prototype and the resultant casting becomes the model from which the wax mold is produced for production. The wax mold is used to replicated the part in wax multiples for producing the tree of wax forms that ultimately are invested and cast to produce the parts.
How do you make a double headed quarter?
The old way was to use a jeweler's saw and cut two genuine quarters in half sideways, like cutting a bagel. Then swap the two face sides and solder them together. The seam on the edge of one of these coins is very easy to see. Today double-sided coins are made automatically by modern machining techniques that are accurate to fractions of a mm. One coin is hollowed out on the back side and the other is planed down to make it thinner. The thinner coin is also ground down a bit on the edge so it's a hair smaller in diameter. Then the thinner coin is popped into the hollow of the other coin and the two snap together like the lid on a plastic sandwich box. Because the seam is at the rim of one face rather than on the edge, it's very hard to detect. A lot of people will find a machined coin and assume it's real because there's no obvious seam, but if you use a high-powered magnifier it will be visible. These novelty items are often called "magician's coins" because they're used in magic tricks. They're also sometimes called "sucker coins", too, because in the old days some people would place a heads-or-tails bet and offer to flip the coin for the bettor. The crook would bet heads, and the other person would be forced to choose tails. Guess who "won"?
Difference between milled steel and stainless steel?
Milled steel is a cheap form of iron-carbon alloy that is subject to corrosion but is malleable and does not suffer from the brittleness issues of Stainless steel. Stainless steel contains additional compounds that reduces atmospheric and hydro-corrosion and increases the hardness of the steel. This makes it more expensive, less malleable and is more likely to suffer from stress fatigue and stress fractures
What are the ratings and certificates for Machined - 2006 V?
Machined - 2006 V is rated/received certificates of: USA:R
How is titanium machined and welded?
Quite like stainless steel. For maching just adapt the parameters (speed, deep...) also depend of the tool. For welding, I heard that you can use the same techniques (TIG, MIG-MAG) as steel but adapt the parameters also (particularly the preheating).
Method of making crankshaft?
I think they are machined forgings.
Can dual mass flywheels be machined?
Dodge/ Cummins does not recommend it
What type of products does Machined Plastics manufacture and distribute?
Machined Plastics manufactures and distributes plastic products that are temperature resistant, dimensionally stable, chemical resistant, tough and impact resistant.
Why is it necessary to have a tolerance on a machined component?
Dimensional tolerances are required for machined parts due to the virtual impossibility of being exact, down to the micron, on every dimension every single time.
Can slotted or drilled rotors be machined in a brake lathe?
Yes. It does not make a difference whether is is the conventional, slotted or drilled rotors. They can all be machined in a brake lathe with the same accurate result.
What is a swarfed surface?
The surface on the machined part where the material is being removed.
This part has carefully machined high spots called lobes?
pushrod
Can uranium change form?
Yes, uranium can be mechanically machined or melted.
When should brake disks be machined?
Whenever you can see or feel grooves in them.
