Korea
Another Stone Age Technological Breakthrough!
2003-12-04
The Huichon Machine Tool Factory of the Democratic People’s Republic of Korea has made ultraprecision stone surface plates of various sizes enjoying popularity among users for their good mechanical operation. They are quite different from the cast iron surface plate which is difficult to process precisely and easy to deform in high temperature. The latter also makes errors because of changed circumstances in inspection and calibration of products. The stone plates are more than two times the cast iron plates in hardness and resistance to abrasion and more than 35 times in resistance to heat. And they keep their shapes unchanged for a long time because they have a few factors of shrinkage and expansion. The nonmagnetic stone plates, which are unaffected by surroundings, bear well with acid and water and produce less vibration and noise. They, ensuring precision of 0.0025 mm per one square meter, have already been introduced into different economic sectors.
Precision rocks, what will they think of next?

#7  Ho hum. We've had precision stone grinding wheels and plates for decades if not centuries. You can order 'em online from a company called Standard Diamond.

Thanks,

#6  Precision engineering (.0025mm/meter) means they are working on nukes, pure and simple.

#5  Swiggles, it's not what they do, it's how they boast about it. It's like that old skit on SNL when the alien spacecraft lands and they order the earth to surrender to them. They boast about this advanced superweapon they have and threaten to use it. Only thing is, when they bring it out, it turns out to be a muzzleloading blunderbuss.

#4  Well, as much as this sounds funny, it's actually a pretty good breakthrough. Assuming they didn't actually steal the technology from a company like Bomb-a-rama mentions.

The company I work for uses a lot of very precise measuring equipment. Mainly for reverse engineering components with very, very tight tolerances. All of the equipment is built upon several inches of marble. And this equipment is state of the art, with each piece costing tens of millions of dollars.

#3  They could have bought something from Starrett or Mitutoyo that fit the bill. Of course, if they want to re-invent the wheel, by all means, they can knock themselves out...

#2  I like how they are comparing it to their previously cutting edge caste iron.
