China Top-Grade Swiss Screw Machine Services

Product Details: Swiss screw machining is a subtractive manufacturing process using Swiss-style machining equipment. It is distinguished by a guide bushing that reduces the distance between the main spindle and the cutting tool, minimizing workpiece deflection. The process involves loading a round bar stock into the machine, held in place by a guide bushing to minimize vibrations. The machine’s headstock slides along the Z-axis, allowing precise cuts while the tools remain stationary. These machines can perform operations like turning, drilling, boring, threading, and milling in one setup. They are equipped with auto bar feeders and coolant systems to maintain precision and extend

tool life. Swiss screw machining is used for high-volume precision manufacturing of small cylindrical parts and products[4].
