In the realm of precision finishing, White Fused Alumina (WA) Honing Sticks are essential tools known for their purity and cutting efficiency. Whether for mass production in the automotive industry or high-tolerance repair in aerospace, WA honing stones offer the perfect balance of hardness and friability.
Here is a comprehensive guide to the features, specifications, and applications of our WA honing sticks.
1. Core Features
(1) High Hardness & Wear Resistance
White Fused Alumina (WA) possesses a hardness second only to Diamond and Cubic Boron Nitride (CBN).
●Benefit: This high hardness ensures sustained cutting ability over long periods, reducing the frequency of tool changes. This directly translates to higher production efficiency and lower operational costs.
(2) Self-Sharpening Properties (Friability)
One of the defining characteristics of WA is its ability to fracture naturally during use. As abrasive grains wear down, they break to expose sharp, new cutting edges.
●Benefit: This continuous self-sharpening action prevents the honing stick from becoming dull (passivation). It ensures consistent cutting performance and prevents "workpiece burn" caused by excessive friction.
(3) Chemical Stability
White Fused Alumina is chemically inert and does not react with the workpiece material.
●Benefit: It is exceptionally suitable for machining sensitive materials like Titanium Alloys and Superalloys, ensuring the purity and metallurgical quality of the finished part.
2. Technical Specifications
We offer a range of customizable specifications to meet diverse machining needs, from rough grinding to mirror finishing.
Abrasive Types
Available in various formulations tailored for different stages: Roughing, Finishing, and Super-finishing.
Grit Sizes
●Standard Precision: #800 – #6000 (Ideal for general precision machining).
●Ultra-Precision: #800 – #10000 and above (Designed for high-precision mirror finishing).
Bonding Systems
The bond determines the strength and behavior of the stick. We offer:
●Resin Bond
●Vitrified (Ceramic) Bond
●Metal Bond
Impregnation Treatments
To enhance performance in specific environments, we provide specialized treatments:
●S / VS (Sulfur Impregnation): Enhances lubrication and significantly reduces machining heat.
●2WA (Wax Impregnation): Provides rust prevention and improves chip evacuation.
●Application: These treatments are crucial for high-precision scenarios requiring low thermal damage.
3. Key Application Areas
Automotive Manufacturing: Engine Blocks
The inner walls of automotive engine cylinders require extreme smoothness combined with a specific texture.
●The Challenge: Creating a "cross-hatch" pattern to retain oil while minimizing friction.
●The WA Solution: Our honing sticks precisely control surface roughness within Ra 0.1 – 0.4μm. This optimization reduces fuel consumption and extends the engine's service life.
Aerospace Industry
In aerospace, tolerance levels are unforgiving.
1. Hydraulic Actuator Precision Honing
Aerospace hydraulic cylinders demand zero-defect sealing capabilities.
●Performance: WA honing sticks achieve a cylindricity tolerance of ±1μm. This precision ensures the absolute stability and reliability of the hydraulic system, keeping leakage rates to a minimum.
2. Turbine Shaft Repair
Restoring worn turbine components requires a delicate touch.
●Performance: WA honing stones allow for precise dimensional restoration. The cool cutting action ensures that the repair process is cost-effective and does not alter the heat treatment properties of the original material.
