RF is the high speed roller feeder machine which equipped with high speed press machine usually. For small metal parts stamping line, this roller feeder always compact horizontal decoiler machine and C type high speed press for fast punching. It is easy to be maintained with less trouble, the feeding speed can achieve 20m/min or 600 SPM( stroke per min). The most important part of this roller feeder machine is the feeding rollers, which is electroplated with chrome to achieve hardness HRC 60-62. All feeding rollers will be tested for the concentricity with +/-0.05mm accuracy. With such high precision process, the feeding speed and accuracy of this high speed roller feeder are stable and the life time is longer.
