The Round Spindle housing for Milling and Boring Head and Spindle Bodies distributed by 4ManPro^® (Elements For Manufacturing Processes) a Hann Kuen Machinery & Hardware, Co., Ltd. BRANCH OFFICE, are made of FC30 Cast Iron, which after undergoing an exhaustive inspection, they are processed by precision drilling and honing. All our spindles are manufactured from alloy steels subjected to high-frequency heat treatment.

The SR SERIES Milling and Boring Heads and Spindles have round-shaped bodies to provide greater performance for Heavy Duty applications in conditions of high effort and continuous work.

These spindles are assembled with precision bearings SKF^® (Germany), NSK^® (Japan) and TPI^® (Taiwan) that maintain the precision of the spindle tip at < 0.02 mm.

Its maximum speed is suitable for mounting on a BS SERIES or HS SERIES CNC Servo Slide, or a hydraulic feed table for your machining applications.

The elements that make up the SR SERIES are described below:
