　　Key Quality Control Measures in CNC Machining

　　1. Material Verification

　　Before any machining process begins, it¨s crucial to verify that the raw materials meet the required specifications. Material verification ensures that the metals, plastics, or composites used have the right properties, such as strength, hardness, and thermal resistance, to withstand the intended application. This step helps prevent defects that could arise from using substandard materials.

　　2. Machine Calibration and Maintenance

　　CNC machines are precision instruments that require regular calibration and maintenance to operate at optimal performance. Calibration involves adjusting the machine settings to ensure accuracy in dimensions and alignment. Routine maintenance, such as checking the spindle, replacing worn-out parts, and ensuring proper lubrication, prevents machine errors that could compromise product quality.

　　4. Dimensional Inspection

　　Dimensional inspection is a critical quality control step that ensures the machined parts meet the specified tolerances. This process involves using precise measurement tools like calipers, micrometers, and coordinate measuring machines (CMMs) to verify the dimensions of the parts. Any deviations from the set tolerances are flagged for correction, ensuring consistency across all produced components.

　　5. Surface Finish Inspection

　　The surface gloss of a machined part can have a significant impact on its characteristics, especially in applications with high friction, wear, or aesthetic regulations. Surface finish checking examines irregularities such as roughness, burrs, or surface deviations. Advanced technologies such as laser scanning and optical gallery profiling can be used to measure surface quality and ensure that the criteria for conditions are met.

　　6. Final Product Testing

　　Before a product is shipped to the customer, it undergoes final testing to verify its functionality and performance. This may include stress testing, load testing, or other application-specific tests that simulate the conditions under which the part will be used. Final testing is the last checkpoint to ensure that the product is fully compliant with the customer¨s requirements.

According to CCTV news, on May 23 local time, Russian President Vladimir Putin signed a presidential order requiring the Russian government to formulate relevant rules to compensate Russia and the Russian central bank for losses caused by the unfriendly measures of the United States, and to allow the use of U.S. assets in Russia. Domestic assets are used to compensate for losses caused by the confiscation of Russian assets in the United States.

The presidential order also involves allowing property owners in Russia to file lawsuits against the United States for illegally confiscating Russian assets in the United States in accordance with Russian law. In addition, the presidential decree also requires Russian courts and government departments to send to the Russian Government’s Foreign Investment Regulatory Commission the specific information on the inventory of the assets of U.S. legal persons and individuals in Russia after receiving relevant compensation requests, and use this as a basis for compensation work.

EU countries will use profits from freezing Russian assets to aid Ukraine

According to a Reuters report on May 21, the Belgian government revealed on the 21st that EU countries have formally adopted a plan to use profits generated by the assets of the Russian central bank frozen by the EU for defense assistance to Ukraine.

Under the EU agreement, 90% of the proceeds from frozen Russian central bank assets will go into a fund operated by the EU to provide military assistance to Ukraine, while the remaining 10% will support Ukraine through other means.

According to reports, ambassadors from EU countries reached a consensus on this matter at the beginning of this month, and the text of the agreement can officially take effect only if the ministers of various countries are stamped and approved.

Frozen assets of Russia’s central bank are reportedly generating huge profits. The EU expects to generate profits of about 15 billion to 20 billion euros by 2027. EU diplomats said Ukraine is expected to receive its first payment in July this year.

A senior Russian diplomat warned that the plan would have unpredictable consequences and said sooner or later the EU would have to return what was stolen to Russia.

Ukraine Foreign Minister Kuleba thanked the EU for the above decision on the 21st, but reiterated that Ukraine’s ultimate goal is to confiscate Russia’s financial assets, not just to benefit from profits.

According to reports, shortly after the Russia-Ukraine conflict broke out in February 2022, the Group of Seven (G7) froze Russian financial assets worth approximately US$300 billion. Since then, the EU and other G7 countries have debated how and whether to use the funds to help Ukraine.

German media: Ukraine systematically attacks Russian oil facilities with drones

Ukraine is systematically attacking Russian oil facilities with drones and achieving results again, German news television channel reported on March 13.

It is reported that three drones caused a fire at an oil refinery in Liangzan prefecture southeast of Moscow. The new Shahjinsk oil refinery in Rostov-upon-Don was also attacked. The latter is reported to be the largest oil refiner in southern Russia.

A source from Ukraine’s State Security Service told the Ukrainian newspaper Truth: we are systematically implementing a well-planned strategy to weaken the economic potential of the Russian Federation. Our task is to deprive the enemy of resources. He said the military’s fuel supply and Russia’s oil revenue for the war would be affected.

Reported that Ukraine hopes that the continued crackdown on Russian oil facilities can significantly reduce Russia’s fuel production. “Spring sowing in Russia will become very difficult, which means food prices will rise sharply,” former Deputy Minister of Internal Affairs Andr é Graschenko wrote on social platform X. Fuel shortages may also push up the prices of other commodities, he said.

A total of 58 Ukrainian drones were shot down by Russian air defense systems from midnight to early morning on March 13, the Russian Defense Ministry said. So far, however, the Russian military does not seem to have found a way to deal with Ukraine’s constantly developing and upgrading drones.

Itar-Tass quoted Kremlin spokesman Peskov as saying on the 12th: our soldiers are taking all necessary measures. He said that the air defense system is operating effectively, and whether the protection of industrial targets should be strengthened is a question to be answered by the Ministry of National Defense.
