I Dont exactly know but got somthing to do with splash lubrication.
How does a contact relay weld?
Too much current cause excessive heat and cuases melting of the relay contacts.
What is shore hardness of material?
Only a hard outer surface.
Whatever the piece is less difficult to penetrate.
What is the Role of Conveyor Drum Pulley?
Conveyor pulley manufacturers company use conveyor drum pulley with conveyor system to drive conveyor belt. Tension and friction between pulley and belt decide the quality of conveyor belting system.
Why a mechanic would choose a long spanner to undo a tight nut?
The mechanic would get more leverage. The rotational force applied to the nut is greater the longer the spanner, assuming the mechanic applies the same amount of force.
Which gas burns the hottest when cutting torch is used?
oxygen supports the combustion of the gas that one uses in the welding/cutting torch. Acetylene combined with Oxygen produces the hottest flame.
Why is stainless steel dangerous to weld?
stainless steel contains chromium. chromium gives off toxic fumes when heated.
How much vacuum is created by centrifugal pump during empty out the tank?
If we install centrifugal pump to transfer liquid from tank,after empty out the tank pump is continiously running,then how much vacuum is created in tank?
What type of micrometer is easiest to read?
A digital micrometer is the easiest to read as it displays the exact reading on a screen.
What is meant by the term flexibility?
An electric power drill is a flexible tool because it can be used for a variety of purposes:
- boring holes
- stirring paint
- polishing
- roughening surfaces with a rotating wire brush
- grinding with a wheel
- turning screws
A garden hose is said to have flexibility because it can be wrapped around corners or coiled up for storage.
A person can be considered flexible is she is willing to lead a group one day, take suggestions from a leader on another day, do library research another day, make a speech to a conference another day, sail a boat on another day. In other words, do a variety of things at various times.
What typy of welding machine do you need to weld steel?
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
Why would the british want to keep the working of industrial machinery secret?
The British wanted to keep the working of industrial machinery a secret so that other countries could not copy them and start their own factories. They wanted to keep their technology to themselves, so they could be more advanced than other countries.
What is the significance of rope bracelets for sailors?
Rope bracelets were used by sailors as good luck charm, among a few other things.
They would wear them to protect again dead seas and doldrums.
What does the first ratchet wrench look like?
It's about 8 1/2 inches long with PxC in the middle-The manufacturer-made of forged steel with a grip from the head till about 1/2 inch from the end. Anyone that has seen a ratchet knows that it has the tip on the head where you can put a new piece or setting on; well on the original its just a hole with a specific size you can't switch out the setting or sizes. It was creud, but it worked at the time.
What technology allows workers to produce a drill long enough to reach oil?
The drilling pipe comes in sections and they periodically stop drilling to add another section. This way they can drill to almost any depth desired.
The physical drilling head on the tip of this pipe is rarely more than a couple of feet long.
What is 7 mm converted into a fraction of an inch so that I can find an inch sized socket that fits?
You can write 7 as a fraction by using 1 as the denominator: 7/1.If you want this as a fractional part of meters, centimeters, kilometers, inches, feet, etc., please clarify what unit you want to convert it to.
Interpolation is a term borrowed from the mathematics field of numerical analysis. Typically the machine tools that are numerically controlled by computer in CNC applications are capable of moving only in discrete, albeit small steps, rather than continuous motion. However, we want many machined objects to have curved surfaces. To make this possible, curved surfaces are approximated using numerous short steps. Interpolation is the mathematical process of calculating approximate points between fixed points on the desired machined surface. Once these are determined the CNC machine is set to work making its cuts between the fixed points and the interpolated points essentially. Various interpolating functions can be used, the simplest being line segments. More sophisticated machinery is capable of circular interpolation.
Please see the links.
Can you buy a metal drill press table replacement?
Yes, you can, but you will have to order it from the company that made your drill.
What is a flat file in metal workshop?
A hand file where both surfaces are flat. Used to file down metal where the surface requires a flat finish. Other files in the work shop are curved concave, curved convex ,triangular and square. Each used to specific shape filing.
What is a coolant in a CNC machine?
A coolant is used to keep the tool tip cool. Keeping the tool tip cool prolongs the life of the tip ensuring the accuracy and consistence of the machined component.
Coolants are mixed with water and are anti-corrosive. If correctly mixed, it will not cause corrosion to any of the machine's parts.
How do you set the G54-G59 Offsets on oi-t series Fanuc controller?
If you are using a probe to set offsets, plug your probe results from Fanuc point probing macro G65P9100. Values from this macro are placed in the following variable by the point probing macro: #125 for X, #126 for Y, and #127 for Z. These can be used to set your G55 thru G59 offset directly or the values can be stored in #900 series write-able variables for doing calculations such as averaging, checking squareness, flatness, etc... The variables that set G55 are as follows. Example for X #5241=#125, for Y #5242=#126, for Z #5243=#127. Add 20 for each coordinate offset after that, IE: #5261, #5262, #5263 for G56, #5281, #5282, #5283 for G57 and so on.
