Tungsten Carbide Rod with R2 Arc Profile for High Wear Resistance and Precision

Product Specification

1. Product Overview

The Tungsten Carbide Rod with an R2 Arc Profile is a high-performance hard alloy rod precision-machined from ultra-fine grain tungsten carbide material. It features a precisely designed R2 arc contour at the front end, combining exceptional wear resistance, high rigidity, and excellent impact toughness. This product is specifically developed for demanding wear environments and high-precision machining applications. It is widely used in mechanical processing, mold manufacturing, precision guiding, and wear-resistant components, making it an ideal choice for enhancing equipment performance and service life.

2. Key Features and Advantages

1. Exceptional Wear Resistance & Long Service Life: Manufactured from high-purity tungsten carbide with a hardness exceeding HRA 90, its wear resistance far surpasses that of high-speed steel and other alloy steels, significantly extending replacement cycles and reducing overall operational costs.
2. High Rigidity and Stability: Possesses an extremely high modulus of elasticity and compressive strength, effectively resisting bending deformation under high-speed or heavy-load conditions to ensure precision and stability in machining and operation.
3. Excellent Impact Resistance: Optimized cobalt binder formulation and sintering process enhance the material's toughness while maintaining high hardness, allowing it to withstand certain levels of intermittent impact load.
4. Precise R2 Arc Design: The R2 arc contour at the rod end is precision ground, featuring accurate dimensions and smooth transitions. This design facilitates stress distribution, reduces stress concentration, and is suitable for machining, guiding, or forming specific profiles.
5. Superior Surface Quality: The rod body undergoes precision grinding or polishing, resulting in a high surface finish and low coefficient of friction, which further enhances wear and galling resistance.

3. Typical Application Areas

• Mechanical Machining: Used as wear-resistant tool setting rods, profile rods, or shanks for special cutting tools in lathes and milling machines.
• Mold Industry: Serves as wear-resistant inserts, guide rods, or ejector pins in molds, particularly suitable for mold cavities requiring arc transitions.
• Automation Equipment: Employed in high-precision guide shafts, wear-resistant rails, and inspection probe rods.
• Wear-Resistant Components: Used as replacement parts for heavily worn areas in equipment within textile, packaging, metallurgy, and other industries, such as bearings, bushings, and roller shafts.

5. Usage and Selection Guidance

1. Selection Guide: Choose the appropriate rod diameter and length based on the actual application's load, impact conditions, wear requirements, and installation space. For applications with significant lateral forces, a larger diameter product is recommended.
2. Installation and Fit: It is recommended to use with high-hardness, wear-resistant bushings (e.g., tungsten carbide bushings). Ensure proper fit tolerance (typically a slight clearance or light press fit) and maintain adequate lubrication.
3. Precautions: Avoid prolonged use in extreme high-temperature oxidizing environments. Although the rod has good toughness, severe direct impact or overload shock should be prevented. During installation, ensure the orientation of the arc end aligns with the design requirements.
