美国Sierra Machinery公司研究出了一项在辊式修磨机上精加工钢管的新技术。实际使用证明,该技术比镗磨机速度快80倍。在辊式修磨机上精加工钢管,生产费用低、周期时间短、精加工质量高。传统的镗磨机加工钢管需5个小时,而辊式修磨机只需要几分钟即可 Sierra Machinery Inc. of the United States has developed a new technology for finishing steel tubes on roll mills. The actual use of proof, the technology faster than the boring mill 80 times. Finishing steel pipe on roller mill with low production cost, short cycle time and high finishing quality. Traditional boring mill steel pipe processing time of 5 hours, while the roller mill only takes a few minutes
