Vacuum silvering rough vacuum pump or rough vacuum pump

Vacuum silvering rough vacuum pump or rough vacuum pump

The rough and rough vacuum pump refers to the vacuum pump that starts from the atmosphere and works in the low vacuum or rough vacuum pressure range after reducing the pressure of the pumped container.

Vacuum silvering maintenance pump

The maintenance pump is when the vacuum system pumping is very small, and the main backing pump cannot be used effectively. For this reason, an auxiliary backing pump with a small pumping speed is additionally equipped in the vacuum system to maintain the normal operation of the main pump or maintain the low-pressure vacuum pump required by the evacuated container.

Vacuum silver plated foreline pump

A foreline pump is a vacuum pump used to maintain the foreline pressure of another pump below its maximum allowable foreline pressure.

​Vacuum silver plating with chromium nitride coating (CrN)

The good anti-adhesion property of CrN coating makes it the first choice coating in processing where built-up edge is prone to occur. After applying this almost invisible coating, the machining performance of high-speed steel or carbide cutting tools and forming tools will be greatly improved.

Vacuum silver-plated titanium nitride coating (TiN)

TiN is a general-purpose PVD coating that increases tool hardness and has a higher oxidation temperature. The coating can be used for high speed steel cutting tools or forming tools to obtain very good machining results.

Improper coating life in vacuum silvering

Proper surface treatment of small round tools can increase tool life, reduce cycle times and improve machined surface quality. However, choosing the right tool coating for machining needs can be confusing and laborious. Each coating has advantages and disadvantages in machining, and choosing the wrong coating can result in lower tool life than uncoated tools, and sometimes even more problems than before the coating .
