Fluid Polishing Versus Conventional Mechanical Deburring

The fluid polishing process (abrasive grain flow process), compared to conventional mechanical processing methods, has the following characteristics.

1. Softness and rigidity, uniformity and control

Abrasive flow processing technology does not rely on mechanical energy and mechanical force to remove the material, processing without obvious strong mechanical force, its processing performance and the strength or hardness of the workpiece material mechanical properties, so it can process a variety of super hard super strong metal materials, as well as special non-metallic materials. The abrasive itself is a fluid carrier, a semi-solid medium with cutting properties mixed with a viscous polymer in proportion to its full strength, relying on the flow energy of the abrasive relative to the surface to be machined. In its normal state the abrasive retains its shape as if it were a solid and is elastic.

2. Machining complex surfaces such as bores, teeth, curved surfaces or irregularities with simple movements

Abrasive flow processing through the piston of the hydraulic cylinder up and down reciprocating motion, under the action of pressure to promote the abrasive can be like a liquid to fill the space of any shape and flow through the aperture, so as to complete the three-dimensional complex surface processing process.

3. Simple tooling, higher efficiency and lower costs

Abrasive flow processing technology is used to process the contact surface between the workpiece and the abrasive without the need for complex tools, fixtures and jigs based on the shape and characteristics of the workpiece, which is incomparable to traditional methods. This significantly reduces the cost of acquiring the large number of tools, jigs and other fixtures required for traditional machining, greatly reducing production and processing costs and increasing machining efficiency.

4. High machining accuracy

Traditional mechanical processing methods use powerful mechanical energy to remove material, so the instantaneous energy density is high, the surface of the workpiece produces strong elastic and plastic deformation, and is prone to the formation of thermal stress, residual stress, cold work hardening and other surface defects. Abrasive flow processing under pressure, so that the abrasive in the surface of the workpiece reciprocating movement, a variety of cavities and cross aperture and edge of the part grinding polishing, chamfering, deburring process, abrasive flow processing of the material cut rate is very low, is a can maintain the accuracy, efficiency and cost of automated finishing processing method!

These are the four main differences between abrasive flow and mechanical deburring, so that in the complex cavity bore, or complex external surface polishing deburring, abrasive flow has irreplaceable advantages.
