process
Our engineers develop high-precision models tailored to your requirements. We select premium steel grades-such as S45C, 42CrMo, or Stainless Steel-based on the required load capacity, durability, and wear resistance.
The process begins with preparing the steel gear blank using advanced CNC turning to ensure exact dimensions. Teeth are then cut using high-precision hobbing or milling machines to achieve the specific module and tooth profile you need.
To ensure long-lasting performance, the steel gears undergo professional heat treatment. Processes like Carburizing, Quenching, or Induction Hardening are used to significantly enhance surface hardness and core strength.
After hardening, gears are precision-ground to achieve a smooth surface and high transmission efficiency. Every gear passes strict quality control, including tooth profile accuracy and pitch error checks, complying with ISO or AGMA standards.
Applications
Industrial Automation
High-precision steel custom gears are the core components in robotic arms, indexing drives, and conveyor systems, ensuring smooth and synchronized motion in smart factories.
Heavy Machinery
Designed to withstand extreme torque and heavy loads, these custom gears are essential for construction equipment, mining machinery, and large-scale cranes.
CNC Machining Centers
Our custom gears provide the high transmission accuracy required for lathes, milling machines, and drilling equipment, maintaining long-term stability under high-speed operation.
Power Transmission
Used in industrial gearboxes, wind turbines, and automotive drivetrains to efficiently transfer power while resisting fatigue and wear over millions of cycles.
FAQ
Q: What information do I need to provide for a custom gear quote?
A: To give you an accurate price, we need your 2D/3D drawings (PDF, STEP, or CAD). Please also specify the material (e.g., S45C, Stainless Steel), module, number of teeth, and any specific heat treatment requirements.
Q: What is the typical lead time for custom gear production?
A: For standard custom orders, the production time is usually 15–25 days depending on the complexity and quantity. If special heat treatment or precision grinding is required, it may take slightly longer to ensure ISO-grade quality.
Q: Can you manufacture non-standard gears with specific modules?
A: Yes. We specialize in non-standard requirements. Our equipment supports a wide module range from 0.1 to 5.0, including both metric and inch systems, for spiral teeth, straight teeth, and various gear racks.
Q: How do you ensure the quality and precision of the gears?
A: Every gear undergoes strict inspection. We use advanced testing equipment to verify tooth profile accuracy, pitch errors, and surface hardness. All products comply with international standards like ISO or AGMA to ensure smooth operation in your machinery.
