Suzhou Krosino Mechatronic Technology Co., Ltd. provides precision CNC machining for industrial chain sprockets. Sprockets are essential for reliable power transmission, and we manufacture them with high-accuracy tooth profiles and robust base materials. Whether you require custom pitch, specific tooth counts, or specialized hardening for high-load applications, our machining services ensure smooth chain engagement and long-term durability for your mechanical systems.
Sprocket performance is heavily dependent on the tooth profile accuracy and material hardness. Our CNC machining process ensures precise tooth indexing and pitch control to prevent chain slapping and noise.
| Sprocket Feature | Typical Functional Tolerance |
|---|---|
| Tooth Profile Accuracy | ±0.05mm (Ensures smooth chain engagement) |
| Bore / Keyway Fit | ±0.01mm to ±0.02mm (Tight fit for power shafts) |
| Total Run-out | 0.05mm (Prevents chain vibration) |
Q1: How do you handle the hardening of sprocket teeth?
For high-load applications, we perform induction hardening on the tooth profiles. This hardens the contact area to prevent rapid tooth wear while leaving the core ductile, which helps the sprocket absorb sudden shock loads without fracturing.
Q2: What materials are best for industrial sprockets?
We typically use carbon steels like 45# or alloy steels like 40Cr. For lightweight or corrosive environments, we also machine stainless steel (304/316). Our team evaluates your torque requirements and operating environment to recommend the right material.
Q3: How do you ensure correct tooth indexing on custom sprockets?
We use high-precision CNC indexing machines and programmed cutting paths to ensure that every tooth is spaced accurately around the pitch circle. This prevents uneven load distribution, which is the primary cause of premature chain stretch and sprocket failure.
