JRLT-15 Abrasive Flow Polishing Machine

Equipment Introduction

JRLT-15 Abrasive Flow Polishing Machine is a precision surface finishing system based on the principles of abrasive fluid dynamics. It primarily consists of an abrasive media circulation system, a bidirectional driving unit, a workpiece fixturing system, a CNC control system, and a filtration and purification system. Its working principle involves using the bidirectional driving unit to force the abrasive media—composed of abrasive particles, a carrier base fluid, and additives—to form a high-speed reciprocating flow across the target surface of the workpiece. By utilizing the impact, grinding, and micro-cutting effects of the abrasive particles, the system removes surface defects, reduces roughness, and enhances overall surface quality. The equipment offers significant advantages, including excellent processing uniformity, zero tool wear, the ability to process complex internal cavities and microstructures, and stable surface quality (reaching below Ra 0.02 μm). It effectively solves surface processing challenges for complex structural components that are difficult to treat with traditional polishing, such as irregular holes, intersecting holes, and deep cavities.

Application Range

This equipment is widely utilized in high-end manufacturing sectors. Specific applications include hydraulic and pneumatic components (e.g., hydraulic valve spools, valve sleeves, cylinder inner walls), aerospace components (e.g., aero-engine blades, fuel nozzles, precision landing gear components), and medical devices (e.g., artificial joint prostheses, surgical instrument cavities, precision channels for diagnostic instruments). It is also used for precision molds (e.g., injection mold cavities, die-casting mold runners, powder metallurgy mold forming surfaces), electronic communication components (e.g., 5G filter cavities, semiconductor packaging molds, precision connector housings), and critical automotive parts (e.g., gearbox valve bodies, engine fuel injectors, turbocharger blades). It is especially suitable for the surface finishing of various metal and non-metal parts with complex internal structures or high-precision surface requirements.
