Abrasive
Jet Machining
with MicroBlasting
Micro-abrasive blasting is powerful enough to drill holes in ceramic substrates, yet gentle enough to cut slots in fragile silicon and glass wafers. MicroBlasting is “shockless,” generating neither heat nor vibration.

Hydrodynamic Seals
Etch shallow channels into the groves or channels of the surface of a seal to crate an air bearing.
Thermocouples
Remove MgO to expose contacts for bonding on heat-sensing harnesses.
Microfluidics
Machine vias in glass and silicon to create through holes for MEMS devices.
Lens Engraving
Etch serial numbers into lenses for ring laser gyros without creating micro-cracks. rn
How to create features of a specific depth
A single pass of the focused abrasive stream from a MicroBlaster can uniformly remove 5 µin (0.127 microns) or less of material depending on the substrate, abrasive, and blast parameters. Given this level of precise and controllable erosion, you simply need to know how to fine-tune the process to suit your application.

5 variables for abrasive jet machining
Using MicroBlasting to cut or etch a part (a process also known as controlled erosion) is a great method to machine many precision parts, from drilling holes in ceramic substrates to cutting slots in fragile silicon and glass wafers. MicroBlasting is “shockless,” generating neither heat nor vibration, meaning microcracks are less likely to form and damage part integrity.

Etching channels to create an air bearing or hydrodynamic seal
Bearings inside turbine engines operate at high speeds in a harsh environment where traditional rolling contact or static bearings would not survive. To improve reliability and fuel efficiency specifically on jet engines, shallow channels are incorporated into the design in which air flows rather than traditional lubricants. The technical challenge is how to create these channels.
