Our aftermarket Caterpillar Loader cutting edges can supply various bevel design, including Double Bevel Flat Edge(DBF),Single Bevel Flat Edge(SBF),Super V Bevel and Wide Bevel Flat Edge(WBF). The bevel angle determines the cutting edge's penetration capability and wear life. A  sharper edge penetrates more easily but also wears down faster , end users should select based on "material density + abrasiveness."

To ensure stable quality,our factory execute strict quality inspection during our entire process :

1. Material Test: we will do raw material spectrum inspection with mill test certificate, and prevent inferior steel substitution.

2. Hardness Test: our technican will do rockwell hardness test for each batch, and ensure hardness controlled at reasonable range, prevent premature wear and chipping.

3. Dimensional Inspection: we will check total length, thickness, width, bolt hole pitch and diameter by caliper & fixture, tolerance controlled within ±1.5mm.

4. Visual & NDT Inspection: we will do visual check for surface cracks, blowholes and casting defects. Magnetic particle inspection available for critical batches to detect internal microcracks.

5. Heat Treatment Inspection: our technican will measure hardened depth to ensure sufficient wear layer, to avoid thin surface hardening and early penetration.

6. Bolt Hole Fitting Test: we will do bolt assembly test, smooth insertion, no oval holes, and flat contact without warping
