小批量或大批量生产的铸件的修边作业仍然用手工完成。这些作业的成本高达生产总成本的20％。用带有磨料的水射流进行修边在技术上是可行的。水射流技术除了在时间和费用上具备优越性以外，它还可改善操作人员的安全和健康条件。
Trimming of small or high-volume castings is still done by hand. The cost of these operations is up to 20% of the total cost of production. Trimming with abrasive water jets is technically feasible. In addition to its superiority in terms of time and money, water jet technology improves the safety and health of the operator.
