High Precision Custom Cutting Machine Gears For Cutting Machines Transmission

High Precision Custom Cutting Machine Gears For Cutting Machines Transmission

Cutting machine gears are precision transmission gears specially designed for various cutting equipment such as metal cutting machines, stone cutting machines, wood cutting machines and plasma cutting machines. Made of high-strength wear-resistant alloy steel through precision machining, heat treatment and precision grinding, they are mainly used for spindle transmission, blade driving, speed regulation, reversing and power distribution of cutting machines. Featuring impact resistance, wear resistance, high speed, stable transmission and adaptability to harsh working conditions, they are core transmission components for cutting machines to achieve high-speed cutting, precise feeding and stable operation, widely used in industrial processing, building decoration, hardware manufacturing and other fields.

Product Features

• Excellent high-speed performance, suitable for high-speed blade driving of cutting machines, with stable operation and no jitter.
• Impact and fatigue resistant, able to withstand frequent start-stop and load impact during cutting.
• High tooth surface hardness and strong wear resistance, not easy to wear or pit when in long-term contact with dust and debris.
• High transmission precision and uniform feeding, ensuring flat and non-deviating cutting edges.
• Compact structure and small size, suitable for narrow transmission space of various cutting machines.
• Small heat treatment deformation, good dimensional consistency, strong assembly interchangeability, and convenient maintenance and replacement.
• Dust and oil resistant, adapting to the harsh working conditions of high dust and debris at the cutting site.

Production Process

• Raw Material Inspection → 2. Precision Forging/Hot Forging Blanks (improve material density and strength)
• Pre-Heat Treatment (Normalizing) → 4. CNC Turning (processing inner hole, end face and reference surface)
• Hobbing/Milling Semi-Finishing (processing tooth profile to ensure basic tooth profile accuracy)
• Carburizing & Quenching Strengthening (improve tooth surface hardness and wear resistance) → 7. Low-Temperature Tempering (remove stress and enhance toughness)
• Precision Grinding of Inner Hole and End Face → 9. Precision Gear Grinding/Shaving (correct tooth profile and improve accuracy)
• Deburring, Cleaning and Sandblasting (remove processing burrs and clean the surface)
• Accuracy Inspection, Hardness Inspection and Flaw Detection (only leave the factory after passing full inspection)
• Anti-Rust Treatment (Galvanizing/Blackening/Spraying) → 13. Packaging and Warehousing
