Multifunction CNC Metal Spinning Machine

The KST650S automatic CNC spinning lathe is a fully servo-controlled forming equipment customized for aluminum, 304/316 stainless steel and copper axisymmetric workpieces. It integrates necking, flanging, deep drawing and seamless one-piece forming in one workflow. It widely manufactures venturi valves, lamp reflectors, cookware, fan cones and auto exhaust shells for HVAC, lighting, kitchenware and automotive factories. With heavy cast iron body and intelligent CNC system, it delivers stable precision, smooth workpiece surface and high efficiency for mass production. All units pass CE safety certification and support customized forming parameters for different rotary parts.

This stainless steel venturi metal spinning machine is specially customized for mass production of HVAC venturi valve tubes and air dampers. As a multi-function CNC spinning lathe, it integrates necking, flanging, curved surface forming and seamless deep drawing in one process to fabricate integrated hourglass-shaped venturi housings from 304/316 stainless steel sheets. Equipped with dual servo hydraulic roller system and Siemens PLC touch screen control, the machine realizes one-time integral forming without welding seams. The finished venturi tube features ultra-smooth inner wall, low air resistance and excellent air tightness, perfectly meeting the high-standard ventilation requirements of laboratories, pharmaceutical cleanrooms and hospital operating rooms. Adopting heavy stress-relieved cast iron frame, the equipment maintains stable precision during long batch production of HVAC air damper components. It is the dedicated forming equipment for ventilation manufacturers to produce pressure-independent venturi valves, effectively cutting secondary processing costs and improving product corrosion resistance.
