Reducing Maintenance, Downtime in Finishing 减少维护，缩短清理时间
Farrar Corp., an iron casting facility in Norwich, Kan.,
U.S., recently installed a drum blast machine from Roberts Sinto Corp., Lansing, Mich., to replace a conventional tum- blast unit.
Japan-based Sintokogio, the parent company of Roberts
Sinto, is introducing advanced designs and abrasive blast technology to the North American market. Te first unit Roberts Sinto introduced with the Sinto Surface Treatment (SST) is the CND Drum Blast. Tese models are capable of cleaning a broader range of castings, including small, thin parts. By design, they require significantly lower mainte- nance than conventional tumble-type blast machines. Farrar’s CNDR-22 Drum Blast machine reportedly
features smooth load/unload capabilities, highly efficient finishing due to oscillation during the blast cycle, and a zero pinch design that virtually eliminates jams in the mill. “Te equipment it replaced was undersized and poorly
constructed, which resulted in high maintenance costs and a lot of downtime,” said CEO and chairman Joe E. Farrar. Roberts Sinto helped Farrar’s staff through the initial startup of the automatic controls, and the new equipment virtually eliminated downtime and maintenance issues. “We have less part jamming in the machine and during unloading,” he said. “We also have less part damage during shot blasting.” Farrar specializes in ductile and austempered ductile
iron (ADI) castings, providing full service casting design, patterns, CNC machining and milling. Te plant currently
法拉公司是一家位于美国堪萨斯州诺威市的铸铁企 业，最近安装了一台罗伯茨新东公司(位于密歇根州兰辛 市)生产的滚筒喷砂机，
以取代原来的转筒喷砂装置。
罗伯茨新东公司的母公司是总部设在日本的新东工 业，为北美市场引进先进的设计和喷砂技术。罗伯茨新 东推出的第一套应用新东表面处理（SST）的是CND滚 筒喷砂机。这些机型能够清理的铸件范围更广，包括小 的，薄壁铸件。按照设计，这些机器所需要的维护比传 统的转筒式喷砂机减少了很多。 法拉公司CNDR-22型滚筒喷砂机拥有流畅的加载/卸 载功能，喷砂周期带振荡达到高效的清理，由于无挤压 的设计，几乎消除了磨料堵塞。 首席执行官兼董事长Joe E. Farrar说“该设备替换的是 尺寸过小以及结构不合理的部分，这些都会导致高额的维 护成本和大量的停机时间”。罗伯茨新东帮助法拉的工作 人员通过初始启动自动监控，新的设备几乎消除了停机时 间和维护的问题。“我们的机器在装卸过程中的堵塞更少 了，”他说， “抛丸过程中的损坏也少了很多。” 法拉专业生产球墨铸铁和等温淬火球铁（ADI）铸
The new Roberts Sinto drum blast machine re- duced maintenance costs and increased uptime for Farrar Corp.
