As a professional manufacturer of domestic polishing equipment, Guangdong Xianjing Polishing Industrial Technology Co., Ltd. has  ed the precision machining field for many years. Its independently developed series of abrasive flow polishing machines, with excellent performance and innovative technologies, have become the preferred solution for surface treatment of complex workpieces. This article will focus on the core advantages and technical features of Xianjing's abrasive flow polishing machines, presenting the unique value of this equipment in industrial processing.

Product Overview and Core Functions

Xianjing's abrasive flow polishing machine is a precision machining device specially designed for workpieces with complex structures. With an installed power of 7.5KW, it combines high efficiency and stability. Its core function lies in achieving surface polishing, deburring, chamfering, and micro-defect repair of various molds and precision parts through abrasive flow machining technology. Whether it is the complex cavities of raw material molds, stretching molds, extrusion molds, or hidden structures such as internal and external gears, spline grooves, cross holes, and special-shaped holes, the equipment can achieve high-precision surface treatment effects that are difficult to achieve with traditional mechanical processing through uniform grinding with flexible abrasives.

The equipment is applicable to a wide range of materials, including metals and non-metals such as copper, aluminum, hardened steel, ceramics, and cemented carbide. It is particularly good at handling surface hardened layers and micro-defects remaining after EDM, laser, or broaching processing, providing a high-quality foundation for subsequent processing of precision parts.

Innovative Technology and Working Principle

The core technology of Xianjing's abrasive flow polishing machine is based on the principle of "three-element collaborative processing":

• Machine Tool System: Fixes workpieces and fixtures through high-precision hydraulic drive devices, accurately controls the flow pressure and trajectory of abrasives, and ensures stable and controllable processing. The equipment supports pressure parameter adjustment, which can optimize grinding force according to workpiece materials and processing requirements, covering the entire process from rough grinding to fine polishing.

• Abrasive Medium: Uses viscoelastic semi-solid carriers mixed with abrasive grains such as silicon carbide, aluminum oxide, and cubic boron nitride to form flexible grinding materials with cutting capabilities. Combinations of different abrasive particle sizes, abrasive types, and carrier viscosities can specifically solve different processing problems—low-viscosity abrasives are suitable for edge rounding and small-channel grinding, while high-viscosity abrasives are good at uniform polishing of wall surfaces and large channels, flexibly adapting to diverse processing scenarios.

• Special Fixtures: As key components for workpiece positioning and protection, fixtures can accurately block non-processing areas, guide abrasives to flow through target surfaces, avoid damage to other parts of the workpiece, and ensure processing accuracy of complex structures.

During operation, abrasives flow back and forth across the workpiece surface under the pressure drive of the machine tool. Through flexible friction between abrasive grains and materials, excess burrs and defects are uniformly removed, ultimately achieving a significant optimization of surface roughness. Some workpieces can even reach a mirror-level effect.

Core Advantages and Application Scenarios

Xianjing's abrasive flow polishing machine has three core advantages:

• Strong Adaptability: Breaks through the limitations of traditional processing, capable of handling "difficult-to-process areas" such as internally curved holes, cross holes, and narrow gaps. It is particularly suitable for precision molds and special-shaped parts in aerospace, automotive manufacturing, electronic communication, and other fields.

• High Efficiency and Stability: Compared with manual polishing or traditional mechanical processing, abrasive flow technology realizes automated batch processing, significantly improving production efficiency. At the same time, it avoids human errors and ensures processing consistency.

• Improved Processes: As a post-processing equipment for broaching machines, deep hole drilling machines, precision casting, and other processes, it can form a complete process chain with Xianjing's planar polishing and double-sided polishing equipment, providing a full set of solutions from rough processing to high-precision polishing.

Its typical applications include: deburring and polishing of complex oil circuit channels in automobile engines, precision treatment of inner walls of micro-holes in semiconductor devices, surface optimization of special-shaped components in medical devices, etc., helping customers improve product performance and service life.
