Microblasting Machines

Microblasting is abrasive blasting on a micron level. These machines are specially designed to handle conventional abrasives in sizes from 25 to 250 microns, and with nozzles that range in size from .015" to .080". Microblasting is ideal for treating very small parts, or for small details on larger parts. Machines are available in both manual and automatic versions.
