Reaming

Q: What should the hole diameter be before Reaming?

The hole diameter before reaming should be approximately 97% of the reamer diameter this should be taken into consideration at the design stage.

Q: What are the recommended speeds and feeds for Reaming?

The same speeds and feeds recommended for drilling are also generally recommended for reaming. Speeds can be reduced by as much as 50% for better diameter control.

Reaming Services tailored to your product's exact requirements.

As we are precision die casting specialists, we cast holes to the specific size for reaming to eliminate any drilling beforehand eliminating the cost of drilling fixtures.

The following table can be used as a general guide to reaming, based on a surface cutting speed of 60 to 90 m/min

What is Reaming?

A reaming operation is designed to enlarge the size of a previously formed hole by a small amount but with a high degree of accuracy to leave smooth sides with a rotary cutting tool called a reamer.
