CNC Dovetail Machining

CNC Dovetail Machining

Improve Dovetail Capabilities

GE uses CNC technology to custom manufacture low stress dovetails for a variety of different "pine tree" style designs. These low stress modifications will significantly reduce the probability of stress corrosion cracking recurring in the wheel, by increasing the radii under the hook fits of the dovetails. The newly machined dovetails will still allow the re-use of old wheels, as the hook-to-hook relationship is not changed.

The dovetail CNC operations are easily modified to accommodate pitting removal or other machining requirements. The programs can be changed in the field or done remotely and then e-mailed to the site to reduce delay.

GE has successfully machined over 150 wheels at customer sites. All wheels are dimensionally checked before and after machining with all readings recorded in a printed report for the customer's files.
