What is Abrasive Jet Machining ?

  • Abrasive jet machining (AJM), also known as pencil blasting, micro-abrasive blasting, and micro-blasting, is a machining process that uses a high velocity stream of abrasive particles to erode material from a workpiece.
  • The abrasive particles are propelled by a gas, usually compressed air, and directed towards the workpiece through a nozzle.
  • The impact of the abrasive particles removes material from the workpiece surface, gradually creating the desired shape or feature.

Abrasive Jet Machining process

Abrasive jet machining is a versatile and powerful machining process that offers a range of benefits for a variety of applications. Its ability to machine hard, brittle, and delicate materials with high precision and accuracy makes it an indispensable tool in many industries.

1. Preparation: The workpiece is first cleaned and prepared for machining. This may involve removing any existing surface contamination or debris

2. Nozzle placement: The nozzle is positioned relative to the workpiece. The nozzle-to-workpiece distance is critical for achieving the desired machining results

3. Gas selection and pressure adjustment: A suitable gas, typically compressed air, is selected and its pressure is adjusted. The gas pressure affects the velocity and impact of the abrasive particles.

4. Abrasive selection and feed rate: The appropriate abrasive particles are chosen based on the material being machined and the desired surface finish. The abrasive feed rate controls the amount of material removed from the workpiece.

5. Machining: The abrasive particles are propelled towards the workpiece through the nozzle. The impact of the abrasive particles erodes material from the workpiece surface, gradually shaping it to the desired form.

6. Removal of debris: The eroded material is removed from the machining area. This may involve using a vacuum or other collection system.

7. Repeat: The machining process is repeated as needed to achieve the desired shape or feature.

8. Post-processing: The machined workpiece may need to be post-processed to remove any remaining abrasive particles or to achieve the desired surface finish.
