Suzhou Krosino Mechatronic Technology Co., Ltd. provides high-precision CNC machining for cam followers and related motion control components. These parts require exceptional surface hardness and dimensional accuracy to handle continuous rolling contact and heavy radial loads. We combine precision grinding and heat treatment processes to ensure your cam followers deliver smooth, reliable motion in automated indexing and material handling systems.
Cam followers must possess superior wear resistance and precise geometry. Our production process ensures internal structural integrity and external surface smoothness, which are vital for reducing friction and system noise.
| Feature Detail | Typical Functional Tolerance |
|---|---|
| Outer Diameter (Rolling Surface) | ±0.005mm to ±0.01mm (Critical for contact precision) |
| Internal Bore / Shaft Fit | ±0.01mm (Ensures stable assembly) |
| Face Run-out | 0.01mm (Ensures smooth tracking) |
Q1: How do you achieve the required hardness for cam surfaces?
We use high-grade bearing steels and alloy steels that undergo localized induction hardening or through-hardening. This provides a wear-resistant surface while maintaining a tough core, which is essential for surviving the high-stress cycles of cam-follower operation.
Q2: What is your process for finishing the outer rolling surface?
The rolling surface is finished via precision centerless grinding. This achieves the tight diameter tolerance and high surface smoothness (low Ra value) required to reduce wear and friction against the cam track.
Q3: How do you manage concentricity between the bore and the outer diameter?
Concentricity is paramount for smooth operation. We utilize dedicated precision jigs and multi-stage grinding setups to ensure the rolling surface is perfectly centered with the mounting bore, preventing vibration and uneven track wear.
