Economic factors in these places, which greatly differ from those of high technology centers, make mechanization impractical. Minimal Capital Cost Each machine costs money. If kept busy, it can make money. If not, it loses money and can increase costs. It is taxed as an asset and it occupies space; consumes heat, light, and electricity; and requires maintenance. Moreover, it performs only one task. New machines are more than a capital cost. They require trained operators. Training is good, but it increases cost and the higher the employee turnover rate, the higher the cost.
Electrochemical Deburring (ECD) will affect surfaces next to the edge. Question marks indicate lack of data or experience. An “S” indicates that the part is probably affected, or it is suspected. Many processes can be modified to prevent the side effects listed, but the operator must be aware of the issue to prevent it. For example, vibratory deburring in a water solution can cause parts to rust, but adding a rust inhibitor can prevent this side effect. pmd 21 Chapter 2: What ’s Right about Hand Deburring?
