Better Positional Accuracy
In today’s manufacturing, holes must be made with precise tolerances to meet requirements. Boring heads do not follow the position of the drilled hole, like reamers. A boring tool positions from the centerline of the machine spindle to provide exact positional accuracy. Because reaming tools only follow the existing hole, poor fit quality resulting in scrap can be an issue.
Reaming tools can cause damage to inserts, resulting in the need for reconditioning and lost production due to this lengthy process. However, boring heads are fast and straightforward to replace if tool damage occurs.
Reaming tools machine a fixed diameter and can be a reliable hole-making process. In comparison to reaming, boring offers far more flexibility for machining different hole sizes with the same tool.
Boring is best for low production jobs and when more stock is in the hole. Reaming works with pre-machined holes that have small amounts of stock. Both have their use, and it is critical to select the correct process to achieve the desired results.
