SF 35 - TIG Welding tube mill built for high standard buyer

SF35 is a TIG Tube Mill built for a Japanese buyer with a plant in Thailand. They are TOYOTA's supplier, thus, a quality tube mill to meet their client's high standards was requested. Sunfone is a tube mill manufacturer from Taiwan with 20+ years of seasoned tube making machine experience, which has permitted them to sell worldwide.

SF35 is a custom made tube mill. It contains 3 welding torches, a belt type bead grinding machine and a wheel type bead grinding machine, a burr free roller cutting with quick mold changing function.

There are only 1-2 tube mill companies providing such high-end belt type bead grinding machines in Taiwan. The belt type bead grinding machine is a newly added item to the tube and pie making machine. Rather than just a wheel type bead grinding machine, SF35 is equipped with both belt and wheel type bead grinding machines. It can achieve client's strict tube roundness and surface standards. SF35 belt type bead grinding machine's bracket is designed based on an Italian machine. As you can see from the video, the cradle's swing range is wide and its automatic belt height adjustment ensures precise grinding performance.

SF35 has three welding torches and mounting brackets to operate short distance weldings. Each torch's holder is built solidly without shaking. Burr Free Roller Cutting is one of the advantages of SF35. When using roller cutting, the burrs curl inside instead of outside to avoid cutting. The cutting range is broad, between 100mm - 6m, and the cutting tolerance is 0.5mm.

SF35 uses PLC control, a SUMITOMO motor and a SUMITOMO hydraulic transmission box, etc.
