Company Introduction
Founded in 1992 in Guiyang, Guizhou Province, Xianfeng has established itself as one of China's most experienced roll grinding machine manufacturers. The company designs and produces CNC roll grinders capable of handling rolls from small work rolls to large backup rolls up to 60 tons, with full CVC profile grinding capability. Xianfeng machines are installed in steel plants across China, Southeast Asia, the Middle East, and Africa. VSAG provides Xianfeng with its Indian market presence — handling machine specification, logistics, installation support, and after-sales service for the subcontinent.
Technology
CNC Contour Grinding
Fanuc and Siemens CNC platforms deliver closed-loop profile grinding with active in-process measurement, achieving ±0.001 mm roundness and profile accuracy.
Active Measurement & Closed-Loop Control
In-process gauging measures roll diameter and profile in real time, feeding corrections back to the grinding head to eliminate operator variability.
CVC Profile Capability
Integrated CVC grinding software produces Continuously Variable Crown profiles for intermediate rolls to any customer-specified taper curve.
Heavy Workpiece Handling
Purpose-designed headstock and tailstock with hydraulic clamping and precision bearings enable stable, vibration-free grinding of rolls up to 60 tons.
