How Our Shop Slashed Their Roughing Time in Half

After a year of using it, our machinists were amazed at the results. In almost every instance, they saw a 50% reduction in roughing cycle times, compared to the way they were doing 5 axis roughing. Wow Turbomachinery components usually use a mixture of 3+2 and 5 axis roughing, followed by 5

Roughing pump

A roughing pump is any vacuum pump (typically mechanical) used to initially evacuate a vacuum system, as a first stage towards achieving high vacuum or ultra high vacuum. The term quot;roughing pumpquot; derives from the vacuum range it works in, quot;rough vacuumquot;, above 1x10 3 torr (0.1 Pa).

pump is needed to rough the system and back the high vacuum Turbo or Diffusion pump. LC MS and ICP MS use a medium capacity pump on the sample injection/system interface, typically a DS402 or a DS602, and a smaller pump to back the system Turbo pumps. MALDI TOF depending on system size, uses the DS102 to the DS602 as roughing or interface pumps.

The vacuum system of TEM Transmission electron microscopy

The roughing pump is a large mechanical contraption which is easy to hear. It is used to pump the chamber from 'air' (atmospheric pressure) when necessary, to pump the specimen transfer chamber (also from atmospheric pressure), and to back the diffusion pump. Because it is used to do so many things, it is usually attached to a 'roughing
