This machine employs a pneumatic drive system, specifically designed for chamfering the ends of small to medium-sized pipe fittings. After manual loading, it automatically completes clamping, feed-in, and retraction processes, offering simple operation and low maintenance costs. Suitable for metal pipes with outer diameters ranging from Φ8 to Φ60mm, it produces smooth chamfered surfaces free of burrs, with machining accuracy consistently maintained within ±0.1mm. Featuring a compact structure and equipped with safety guards, it is ideal for flexible deployment in workshop environments.
