Custom High Wear Resistance Tungsten Carbide Center Bushing with ±0.01 mm Tolerance and Long Life Span

This tungsten carbide (WC-Co) center bushing is custom developed for high-precision rotating machinery, grinding machines, lathes, and automated equipment. Manufactured using ultra-fine grain tungsten carbide matrix with a cobalt binder, and formed via isostatic pressing and precision sintering, it is specifically designed to withstand high rotational speeds, high impact loads, and severe abrasive conditions in center support and guidance applications. Fully customized solutions for non-standard dimensions, special shapes, and compound angles are available to meet your most demanding wear resistance and geometric accuracy requirements.

• Headstock center bushings on CNC cylindrical/internal grinding machines
• Live center inner sleeves on heavy-duty lathes and roll lathes
• Center bushings on precision dividing heads and rotary tables
• Auxiliary support bushings on ultra-high-speed motorized spindles
• Wear-resistant guide bushings on laser cutters and winding machines

1. Requirement confirmation - Provide drawings, operating conditions and life targets
2. Material recommendation - Select WC-Co grade based on impact toughness and cost
3. Blank forming - Molding/isostatic pressing + vacuum sintering
4. Precision machining - ID/OD grinding, coordinate grinding, wire EDM
5. Inspection report - Dimensional report, hardness, density, microstructure

• Precision assurance - Dedicated grinding machines and ZEISS CMM inspection
