In the overnight international foreign exchange market, the European Central Bank and the Bank of England kept the interest rate unchanged, and the European currency rose sharply. China's trade data is better than expected and the latest data shows that the US employment situation is stable, which makes the risk sentiment rise significantly and drives high-yielding currencies to strengthen. As of the close of the New York exchange market overnight, the US dollar index fell below the 80 mark to 79.75, a drop of 0.98%. In this context, the central parity of the RMB against the US dollar rose significantly on the 11th.
According to the latest data from the China Foreign Exchange Trading Center, the central parity of the RMB against the US dollar on January 11 was 6.2712, a significant increase of 81 basis points from the previous trading day, setting a new high since May 4, 2012.
In the inter-bank foreign exchange market, the spot price of the RMB against the US dollar opened higher and higher on the 11th. However, the upper limit of trading volatility based on the mid-price of the 11th is 6.2085. So far, the spot exchange rate has not touched the “new limit†level for 20 consecutive trading days.
In the overseas non-deliverable forward (NDF) market in recent trading days, the one-year US dollar-to-renminbi quotation continued to fall, closing at 6.2685 on the 10th, representing approximately 0.17% of the RMB for the 10-day median price.

Market participants said that the renminbi is still supported by fundamental factors, and there are still certain medium- and long-term appreciation pressures. However, considering the slowdown of China's economic growth, the increasing two-way international short-term capital flows, and the increasing foreign investment of Chinese companies, the renminbi continues to be single. The basis for substantial appreciation has ceased to exist.
Industrial applications editor broadcast
Whetstone sintered corundum (ruby) : A kind of microcrystalline corundum product sintered at high temperature. It has a compact and delicate structure and high hardness and strength.
The products are rosy red. The products are small grinding wheel type whetstone, standard type whetstone and grinding head type whetstone. When grinding the workpiece, it can maintain sharp edge and stable geometry for a long time.
It is suitable for forming and grinding of instrument industry, precision parts, micro cutting tools, tools and precision abrasive tools, etc. The precision surface roughness of machining can reach about 0.05μm.
Product SPECIFICATIONS: flat sand wheel whetstone with diameter less than 100 for small grinding wheel type, whetstone with various geometric shapes less than 200*50*25 for standard type, whetstone with diameter less than 25 for grinding head type.
Grinding method
About diamond grinding paste, particle size from W40 to W0.5. W40 is the coarsest, with a large amount of grinding, and W0.5 is the smallest. It is used for polishing, and it does not anneal, and it can also grind the hard knife.
Method of use:
The coarse W40 abrasive paste applied to borotartar can accelerate and increase the grinding amount without annealing.
Then, AFTER the rough grinding paste on the knife is cleaned, W0.5 grinding paste is applied to the ruby or natural jade for polishing, and the effect thrown out is a mirror.
Green silicon carbide, white corundum, brown corundum of these three kinds of whetstone hardness is not enough, coupled with a little coarse particle size, easy to grind out the cross, and the other three kinds of whetstone in polishing, grinding will not annealing.
If the particle size is greater than 1000, there is no difference. It mainly depends on the grinding paste used. When the grinding paste of W1.5 is applied to the ruby with 1000 mesh, its grinding effect is the effect of the grinding paste of W1.5, that is, the effect of the whetstone with 2500 particle size
