Straightness after two rolls straightening mahcine

≤0.3mm/m except for not spring steelor special steel.

≤0.6mm/m only for spring steel or High strength and toughnessspecial steel.

 Remarks:
1) About 2 roller straightening machine: The hardnessdifference (HB) of one bar must be≤±10 (HRC difference≤±1)Raw material hardness no more than 38HRC.(The raw material needs to be annealed before process to reduce its hardness. Otherwise, the cutting insert andstraighteningrolls will be easily damaged.)
2) Because of the performance difference,dia of two ends (about260mmlength each end) will be changed a little after straightening. The straightness of two ends for bright bar is about 0.5mm/m, 0.3mm/m for centralpart(about 0.8mm/m for two ends of spring steel ). Diameter tolerance in head and end of bright baris obvious. The end diameter tolerance is about ±0.4mm; Other diameter tolerance of onebar: Φ10~30, ≤0.03mm; Φ30~40, ≤0.04mm.
