NXF UNS N10276 Alloy C276/B366/2.4819 Application Wood Cutting 18in CNC Alloy C276 Laser-welded Circular Saw Blades

1.Raw Material Preparation & InspectionSelect high-purity Hastelloy C276 alloy powder and high-strength alloy steel plates as the raw materials for cutting tips and saw blade bases respectively; conduct strict chemical composition and mechanical property tests on the raw materials to ensure they meet the standards for corrosion resistance and structural strength.Cutting Tip Forming

2.Press the C276 alloy powder into the preset tooth shape through cold isostatic pressing, then sinter it at a high temperature of 1200–1300℃ in a vacuum furnace to form dense, high-hardness cutting tips with precise dimensions.Saw Blade Base Machining

3.Cut the alloy steel plates into circular blanks of specified diameters via CNC cutting, then perform precision turning and milling to process the inner hole, positioning steps, and balance holes; carry out surface grinding to ensure the flatness of the base and the accuracy of the welding surface, and finally conduct stress relief annealing to eliminate machining internal stress.Precision Positioning & Pre-welding Treatment

4.Fix the saw blade base on a specialized positioning fixture, and accurately place the sintered C276 cutting tips in the preset tooth slots of the base through a visual alignment system; clean the welding surfaces of the base and tips with ultrasonic cleaning equipment to remove oil stains, oxides, and impurities, and then dry them thoroughly.Laser Welding

5.Adopt high-energy fiber laser welding equipment, set the optimal welding parameters (laser power 300–500W, welding speed 5–10mm/s), and perform localized welding on the contact surfaces of the cutting tips and base; the high-energy laser beam melts the welding interface quickly to form a dense metallurgical joint, and the ultra-short welding time minimizes the heat-affected zone, avoiding the performance degradation of C276 alloy and the deformation of the base.

6.Post-welding TreatmentConduct a full inspection of the welding joints using a magnifying endoscope to check for defects such as cracks and air holes; perform grinding and polishing on the welded cutting tips to ensure the consistency of tooth shape and cutting edge sharpness, and carry out dynamic balance testing on the whole saw blade to meet the high-speed rotation requirements.

7.Surface Coating & Corrosion ProtectionApply a layer of anti-corrosion and wear-resistant coating on the surface of the saw blade base through physical vapor deposition (PVD) technology, and perform passivation treatment on the C276 cutting tips to further enhance their corrosion resistance in harsh environments.

8.Final Inspection & PackagingConduct comprehensive performance testing, including hardness testing of cutting tips, tensile testing of welding joints, and simulated cutting testing of target materials; mark the product model, specifications, and batch number on qualified saw blades, then package them with anti-rust paper and moisture-proof boxes for storage and delivery.
