Counterfeit Gold-Plated Tungsten Bar-1

The following article is talking about the story of counterfeit gold-plated tungsten bar, written by unknow person.

In his March 2 column, he told about the news story where an employee at the world’s largest private refinery had discovered a gold-plated 500 gram gold bar received from an unidentified bank.  His column included an internet link where readers could themselves view the German television station report.

As is common for his columns, this particular one was picked up by several other websites.  This particular column inspired a relatively harsh response from Robert Bradshaw.  In an essay Robert wrote that was posted yesterday at http://www.marketoracle.co.uk/Article17820.html, Robert took me to task for repeating the story that China’s central bank last year had received at least four counterfeit gold-plated 400 ounce tungsten bars.  Robert seemed concerned that he was perpetuating a myth about a massive number of counterfeit gold-plated 400 ounce tungsten bars that were supposedly manufactured during the 1990′s at the behest of the US government.  Allegedly, about half of them were shipped to Fort Knox.

Until today’s column, he have never referred to the rumor of large numbers of counterfeit gold bars supposedly stored at Fort Knox.  he is well aware of the details of this rumor but, like Bradshaw, the possibility of the whole story being true is pretty far-fetched.  He would need to dig up more hard confirmation of its veracity before discussing it.  If such verification were available, I’m sure that this story would be headline news in the mainstream financial press.

The precious metals markets are not transparent.  To get the best idea of what is really happening means listening to sources that often cannot be independently double-checked.  In his writings, he tries to be careful to listen only to those sources that have developed a track record of reliability.  In this manner, he can often discern the truth long before it is publicly disclosed.

Tungsten Carbide Keyway Broach Introduction

Tungsten carbide keyway broach, as its name implies, is a kind of cutter using for splining. 
 
Types of keyway:
Woodruff keyway has the same keyway size and limit deviation with flat key keyway. Therefore, the tungsten carbide keyway broach can be used in both of them.
Taper key keyway is 0.5~1.3mm shallower than flat key keyway. The groove depth of guide sleeve should be increased if the standard keyway broach is used in splining taper key keyway at one time. But if it is doing for many times (b≥14mm), then the gasket thickness should be calculated again. 
Thin flat key keyway is 0.9~3.5mm shallower than flat key keyway, and the groove depth of guide sleeve during splining at one time should be chosen based on the guide sleeve size a. But if it is doing for many times, proper gasket thickness should be selected.
 
The characteristics of tungsten carbide keyway broach:
I. It has large broaching allowance and teeth number, therefore if the groove is quite deep, then the splining should be done by two times.
II. The broaching surface roughness is relatively high (Ra 2.5~1.25 μm or even higher). When low surface roughness is required, keyway broach with lateral wiper should be adopted.
III. When the guide sleeve is not long enough, the broach may bend upwards and even break during operation.
IV. Edge-line of teeth with enough width should be guaranteed in order to increase broaching stability.

Tungsten Carbide Slotting Cutter Introduction

Tungsten carbide slotting cutter, a type of gear machining tool, is gear-shaped or rack-shaped. It can be used in machining inner gearing and outer gearing spur gears and helical gears through generating method. 
 
The precision of standard tungsten carbide slotting cutters can be divided into class AA, class A and class B according to the international standard. Normally, they are used to machine gears with precision of class 6, class 7 and class 8 respectively. Gears that need shaving or grinding again for the needs of machining should adopt pre-shaving or pre-grinding slotting cutters respectively to ensure there is a certain amount of machining allowance on the gear surface. Therefore, the teeth shape of these slotting cutters needs special design.
 
Tungsten carbide slotting cutters can be classified into four types according to its shape: disk, bowl-shaped, cylindrical, taper-shank. Disk slotting cutters are mainly used in machining inner gearing and outer gearing spur gears, helical gears and herringbone gears. Bowl-shaped gears are generally used to machine inner gearing spur gears with circular bead, which are different from disk slotting cutter in that when they work, nuts can be placed inside the slotting cutter and thus will not hamper machining. Cylindrical slotting cutters are used in machining inner gears and outer gears with small modules. Taper-shank are mainly used in machining inner gearing spur gears and helical gears.

Tungsten Carbide Gear Shaving Cutter Introduction

Tungsten carbide gear shaving cutter is a kind of finish machining cutter used in the involute cylindrical gear machining. When doing gear shaving, the cutting edge of gear shaving cutters shaves a thin layer of metal along the workpiece surface, which can effectively improve the precision and gear surface quality of the gears being shaved. It has high machining efficiency and long tool life and thus is the most widely used tool in the mass production of cylindrical gears with medium precision.
 
In the teeth surface of tungsten carbide gear shaving cutters, there are many narrow grooves. The cutter cuts beard-shaped thin chip from the gear surface during machining, which is the origin of its name. Generally, it is applied to do finish machining towards gear teeth after gear hobbing and shaping.
 
Tungsten carbide gear shaving cutters, used to machine inner and outer cylindrical gears with straight teeth and helical teeth, can achieve a high productivity and good surface finish of workpieces. There are also turbine gear shaving cutters for machining sophisticated turbines, whose basic worm types and parameters should be the same as that of the working worms matching with the turbine. Just like the gear shaving cutter, it also has many narrow grooves on the helicoid to form the cutting edge and hold chip. Turbine gear shaving cutters are difficult to manufacture, and thus they are used only when machining of turbines with high precision requirements is needed.

Tungsten Gold Plated Bar Story -- Aliens hunting for gold on Earth? 2

“We are at the heart of this global control because of our mineral resources,” he said.

On the first day of the conference, all the speakers agreed that like humans who had the potential to be both good and bad, so too was the population of galactical beings.

Extra-terrestrials were also not dissimilar to politicians, who pushed their own agenda for material gain.

“They came to Earth looking for gold. We are all still obsessed with gold,” he said.

The research, according to Tellinger, showed that the extra-terrestrial “Annunaki” came to Earth around 300,000 years ago to look for gold, and that they were also responsible for cloning their own genetic structures and creating mankind.
