Features of this product:
Durable Material Selection
Premium raw materials are carefully selected. Defective raw materials are rejected through professional testing. Quenching and tempering heat treatment, together with rust removal pretreatment, are applied to optimize mechanical properties, laying a solid foundation for the cutter ring’s durability and corrosion resistance.
High-Precision Machining
Leveraging imported CNC lathes and grinders, strict tolerance control is achieved. We follow the standardized procedures of rough turning, precision grinding, chamfering and deburring to ensure stable dimensional and structural accuracy.
Complete & rigorous QC system
A complete inspection system combining 100% full inspection and sampling inspection is implemented. Finished products undergo comprehensive testing covering dimensions, hardness and other key parameters. Sampled products are subjected to simulated working condition tests. Qualified products are rust-proof packaged with a unique traceability code to guarantee zero defects before delivery.
