Description
hardware flow control. It is an ideal choice in the field of industrial automation.
Cryo-electron microscopy can take high-definition 3D “color photos” of microstructures and is a
powerful tool for life science research. The production capacity of transmission electron microscopes
is one of the foundations of cryo-electron microscope manufacturing capabilities. Currently, there are only three manufacturers in
the world that produce transmission electron microscopes, namely JEOL, Hitachi, and FEI. There is no
domestic company that produces transmission electron microscopes. The tools used to match the
cryo-electron microscope need to be original. If the parts are broken and you
can’t find anyone to repair them, you can only wait for the parts to arrive in the mail and replace them.
For Chinese cryo-EM users, this experience may last for a long time.
Tunneling machine main bearing 19″My own tunnel boring machine has to use someone else”s main
bearing” (Science and Technology Daily, June 7)
The main bearing, known as the “heart” of the full-section tunnel boring machine, bears the main load
during the operation of the tunnel boring machine.
It is a key component of the cutterhead drive system and works in very harsh conditions. Compared
with traditional rolling bearings with a diameter of only a few hundred millimeters, the main bearing of a
tunnel boring machine is generally several meters in diameter. It is the most complex bearing and requires
hundreds of manufacturing processes. In terms of the manufacturing capacity of the entire boring machine
, domestic boring machines are close to the world”s most advanced level, but the most critical main bearings
all rely on imports. Germany”s Rothe Ed, IMO, FAG and Sweden”s SKF occupy the market.
