Welcome to Henan San Kuang Machinery Technology Co., Ltd. As a trusted manufacturer established in 2014, we specialize in custom hobbing machining for helical gears and sprockets. Our expertise covers module 1.5 to 8, using high-grade 45# steel combined with precision CNC turning. With a factory spanning 10,000–30,000 m² and over 50 skilled professionals, we deliver components that meet the toughest performance standards for industrial applications worldwide.
Our custom hobbing service ensures accurate tooth profiles, smooth operation, and extended service life. Whether you need helical gears for speed reducers or sprockets for chain drives, we tailor every aspect—from material selection to final finishing—to your exact drawings. This flexibility allows us to serve diverse sectors including automotive, mining, agriculture, and heavy machinery.
Product Features & Technical Specifications
- Material Excellence: 45# medium carbon steel offers excellent strength, wear resistance, and machinability, making it ideal for high-load gear and sprocket applications.
- Wide Module Range: Capable of producing helical gears and sprockets with module 1.5 to 8, covering a broad spectrum of pitch sizes.
- Hybrid Machining: Combining hobbing (for precise tooth geometry) with CNC turning (for accurate cylindrical features and bore finishing) ensures tight tolerances and concentricity.
- Customizability: Full customization available—tooth count, helix angle, hub design, keyways, surface hardness (heat treatment optional), and coating.
- Quality Control: Each part undergoes dimensional inspection using coordinate measuring machines (CMM) and gear testers to guarantee compliance with your specifications.
- Heat Treatment Options: Induction hardening, carburizing, or nitriding can be applied upon request to enhance surface durability.
| Parameter | Range / Value |
|---|---|
| Module | 1.5 – 8 |
| Maximum Diameter | Up to 1000 mm (customizable) |
| Tooth Profile Accuracy | DIN 6–8 or equivalent (per request) |
| Surface Finish | Ra ≤ 1.6 µm (CNC turning) |
| Heat Treatment Hardness | HRC 50–60 (optional) |
| Material | 45# Steel (equivalent to AISI 1045) |
Our advanced CNC turning centers ensure concentric bores and precise outer diameters, while our hobbing machines cut helical teeth with consistent lead and pressure angle. We can produce both left-hand and right-hand helix orientations, as well as multi-start gears. For sprockets, we offer standard tooth profiles (ANSI, ISO) or custom designs to fit your chain type.
Benefits to Your Business
- Reduced Downtime: High-accuracy gears and sprockets from our facility minimize noise, vibration, and premature wear in your equipment.
- Cost-Effective Customization: We offer competitive pricing for small to medium batches without compromising quality—ideal for prototyping or replacement parts.
- Fast Lead Times: With in-house machining and heat treatment capabilities, we streamline production and reduce delivery cycles.
- Global Export Expertise: We ship to North America, South America, Europe, Asia, Africa, and Oceania, handling logistics from Shanghai, Lianyungang, Qingdao, or Tianjin ports.

Frequently Asked Questions (FAQ)
- What is the minimum order quantity (MOQ) for custom helical gears? Our MOQ is flexible; typically 1 piece for sample orders, and we welcome both prototype and production quantities.
- Can you provide heat treatment for 45# steel gears? Yes, we offer induction hardening, carburizing, and nitriding as optional processes to improve wear resistance.
- How do you ensure the accuracy of hobbing for helical gears? We use CNC hobbing machines with real-time monitoring and perform CMM inspection on tooth profile, lead, and pitch.
- Do you accept drawings in formats other than CAD? Yes, we accept PDF, DXF, STEP, IGES, and other common formats. We can also reverse engineer from a physical sample.
- What is the typical lead time for a custom sprocket order? Lead time depends on complexity and quantity. For a standard single-piece order, it is typically 15–25 working days after drawing approval.
- Can you produce sprockets for non-standard chains? Absolutely. We can customize tooth profile, pitch, and hub design to match your chain specifications.
- What coating or surface treatment options do you offer? Options include black oxide, phosphating, zinc plating, and painting. Please specify your requirement.
- Do you provide quality certificates for each batch? Yes, we can issue a material certificate and inspection report upon request.
