  • Page 2 AIRBRASIVE® MICRO ABRASIVE BLASTING TECHNOLOGY Airbrasive® Jet Machining is a process in which high pressure air and very fine powder are blended in a chamber to form an abrasive mixture. This mixture is then sent through a small, precisely machined nozzle. The result is a highly accurate abrasive stream that can be used for cleaning, cutting, drilling, deburring, and finishing all types of surfaces.
  • Page 3 ANGLE OF IMPINGEMENT The angle at which you hold the nozzle regulates the speed and efficiency by which material can be removed from the work piece. There are two theories at play here, one based on material removal by brittle failure and the other on material removal by ductile failure.

  • Page 4: Section 1: Introduction And Description

    Many compressed air lines are contaminated with moisture, oil, and dirt, which are detrimental to the performance and operation of the Unit. Moisture filters and unloaders must be used. These items can be purchased directly from Airbrasive Jet Technologies, LLC.
  • Page 5 Section 1a: Description of Components (Sorted Alphabetically by Part #) AC107 | AUXILIARY CHAMBER The purpose of the auxiliary chamber is to store powder and keep the mixing chamber level constant. This allows the mixing chamber to feed a constant amount of powder into the air stream. AC118X2 | MIXING CHAMBER ASSEMBLY When the mixing chamber is vibrated, powder falls through small holes in the orifice plate assembly and is entrained into the air stream flowing through the chamber base.
  • Page 6 AE193 | BLEED SOLENOID VALVE Controls air pressure to bleed valve assembly. When the SYSTEM POWER SWITCH is set to "On", the solenoid allows air to enter the assembly. This closes the pinch tube within the assembly. When the SYSTEM POWER SWITCH is set to "Off", the solenoid blocks the air from entering the assembly, thus opening the pinch tube.
  • Page 7 AR139 | RELIEF VALVE If primary system pressure is excessive the relief valve will pop open to reduce it. Once the pressure has been lowered the relief valve will reset automatically. AR140 | CHAMBER PRESSURE ADJUSTMENT Regulates incoming air line pressure to the desired level in the mixing chamber. This regulates the powder cutting pressure. This regulator is not field repairable.

  • Page 14 Unit. If the Vibrator does not function properly while under warranty, it must be removed and returned to Airbrasive Jet Technologies, LLC, for readjustment and/or repair. To remove the assembly, disconnect all electrical wires and pneumatic hoses (and tag) from the vibrator (22) and mixing chamber (17).
  • Page 15 The auxiliary chamber (15) does not normally require maintenance unless a new O-ring is needed. When removing the O- ring make certain the old one is completely removed from its groove, and no parts of it fall into the chamber. If they do, remove them.

  • Page 16: Section 5: Service Tips

    C. Reused, contaminated, or improper powders. Such powders can decrease flow or clog the Unit completely, especially at the mixing chamber orifices and at the hand piece nozzle. Never reuse powder. Use of Airbrasive’s ABRASIVE Powders exclusively is recommended. We strongly recommend against the use of other commercial powders because they are rarely classified adequately for use with the AIRBRASIVE apparatus, causing needless maintenance and repairs.
