Hydraulic system pollution control and filter selection considerations

Hydraulic system failure 80% of the above is caused by oil pollution, control oil pollution can extend the hydraulic components and hydraulic oil life, to ensure continuous and reliable operation of the system. The hydraulic system of oil pollution control there are two main band saw measures: First, to prevent pollutants into the system, the […]

Scientists have developed the first can be indirectly compatible silicon chip germanium tin semiconductor lasers

Swiss scientists have successfully developed the first group consisting only of carbon (Group IV) composed of ‘germanium and tin semiconductor lasers’, which means that it can be compatible with other elements of the family, such as silicon and lead. To put it more generally, this study is equivalent to turning on the chip in the […]

Punch safe production, the key to the correct operation Standard punch

Punch safe production, the key to the correct operation Standard punch press operating procedures and methods to ensure personal safety, equipment safety and product quality and stability. Punch is a great risk of machine tools, we must firmly establish the idea of ​​safety first, we must strictly operational procedures to prevent accidents. Punching the right […]

History of Punch – From Induction Synchronizer to Digital Display Technology

In our country is the use of induction synchronizer and grating sensor, initially as an angle encoder, and then developed into a linear displacement sensor. The initial use of the field is on the military, and then measuring instruments, not to have a digital display only a few punch, and then have the job response […]
