在设备安装的管道工序,常以J3G—400型型材切割机和65型套丝机配套使用,有断管、套丝等功能,能方便施工,减轻劳动强度。但是,在实际施工中,遇到断管毛边或小工具需打磨等工作,常有就便在型材切割机砂轮片两侧打磨的现象。由于切割机配备的是φ400×3×φ30毫米的纤维增强砂轮片,侧向受力性能较差,其两侧是不准磨平的。若在其两侧打磨,极易引起砂轮片碎裂,损坏机械设备,发生安全事故。所以,虽制订有安全条例,仍不能避免之。
Pipeline installation process in the equipment, often with J3G-400 profile cutting machine and 65-type threading machine supporting the use, there are broken pipe, set of wire and other functions, can facilitate the construction and reduce labor intensity. However, in the actual construction, there are some problems such as the need to grind the broken edges or the small tools, etc., and the phenomenon of grinding on both sides of the grinding wheel of the profile cutting machine often occurs. Since the cutter is equipped with a φ400×3×φ30 mm fiber reinforced abrasive disc, the lateral force performance is poor, and both sides are not allowed to be flat. If it is polished on both sides, it can easily cause the fragmentation of the grinding wheel, damage the mechanical equipment, and cause a safety accident. Therefore, although there are safety regulations, they cannot be avoided.
