machining of ultra-high vacuum (UHV) components and assemblies

Total Planning machines parts for a wide variety of industries. Within the framework of scientific research, our customers need their parts to be machined in accordance with the UHV standard (10-7 – 10-11 mbar). These specifications form part of the application of UHV in their assembly and are necessary to reduce surface contamination by reducing the number of molecules that reach the part in a given time period. All machining work must be scrupulously controlled to ensure that no foreign matter is embedded in the surface of the material.

General specifications

Accordingly, each one of the machining requirements for UHV conditions must be met:

Inorganic cutting fluids

Viscous organic lubricants must not be used.

Clean machines

Cleaning and replacement of the cutting fluid after each change of material to be machined for UHV items.

special tools

New, special tools for each new material. Cleaning is essential and important throughout the entire process.

It is necessary to clean the elements before, during and after each manufacturing process, taking great pains to ensure there is no cross contamination between “clean” and “dirty” components.


All materials used must be compatible with UHV, such as:


AISI 304L, 304LN, 316L, 316LN, 321, 347


5086, A-6061-T6, A-6063-T6
