Tungsten Cemented Carbide Balls play a crucial role in machining. Their high hardness, wear resistance, compressive strength, corrosion resistance, and thermal stability make them an ideal choice for a variety of machining scenarios. The following are the main roles of Tungsten Cemented Carbide Balls in machining:
1. As a Precision Grinding Media
High-Precision Surface Treatment: Tungsten Cemented Carbide Balls are commonly used in ultra-precision grinding and polishing processes, such as those used for machining high-precision parts like optical components, semiconductor wafers, and mold cavities. Their high hardness and uniform sphericity ensure nanometer-level surface roughness, meeting the demands of precision manufacturing.
Reduced Tool Wear: During the grinding process, Tungsten Cemented Carbide Balls exhibit minimal wear and maintain long-term dimensional stability, thereby extending tool life and reducing machining costs.
2. As a Measuring and Calibration Tool
Standard Balls and Gauges: Due to their high precision and stability, Tungsten Cemented Carbide Balls are widely used as calibration standards for precision measuring equipment such as coordinate measuring machines (CMMs) and laser interferometers, ensuring the accuracy of measurement results.
Aperture and Roundness Testing: In mechanical part inspection, Tungsten Cemented Carbide Balls can be used to measure geometric parameters such as aperture and roundness. Their high hardness prevents measurement errors caused by contact deformation.
3. As Wear-Resistant Components and Guide Elements
Bearings and Balls: Tungsten Cemented Carbide Balls can be used in bearings subjected to high loads and high-speed rotation. Their high hardness and wear resistance significantly extend bearing life and reduce maintenance frequency.
Guide Devices: In automated equipment, Tungsten Cemented Carbide Balls can be used as guide balls to ensure the smoothness and precision of moving parts.
4. As a Shot Peening Medium
Surface Strengthening Treatment: Tungsten Cemented Carbide Balls can be used in shot peening processes. By impacting the metal surface at high speed, they introduce residual compressive stress, improving the fatigue strength and corrosion resistance of the part.
5. As an auxiliary tool for special machining processes
Ultrasonic machining: In ultrasonic vibration machining, Tungsten Cemented Carbide Balls can act as amplitude converters, transmitting high-frequency vibrations to the machining area and improving machining efficiency.
6. As a key component in molds and fixtures
Mold positioning and clamping: Tungsten Cemented Carbide Balls can be used as locating pins and clamping balls in molds. Their high hardness and wear resistance ensure long-term mold precision and stability.
Fixture guides: In precision fixtures, Tungsten Cemented Carbide Balls can serve as guide elements to ensure repeatable positioning accuracy during workpiece clamping.
