Overboring Holes and Flange Facing 97" OD Flange Portable Machining
Field System Machining recently completed two additional portable machining work scopes at the same mill where we completed the 25,000 horsepower motor pedestal field machining project (see blog post "Motor Pedestal On-Site Machining Steel Mill Outage").
The first project required over boring seventy-five existing flange holes to 1-5/8" OD,
approximately 6" deep. FSM provided four men working continuously for fifteen hours to complete the scope on time.

Drill Baby, Drill! We were allowed up to one fifteen hour day to oversize these holes using portable boring machines.

After oversizing the holes we were required to machine the 97" OD x 90" ID flange, removing enough stock to true up the surface.

Field System Machining completed these two small on-site machining projects on time and on budget, making for a very happy customer. Regardless of whether your project requires six machines and twelve men per shift, around the clock, or one machine and two men working twelve hour weekdays only, Field System Machining can handle your portable machining, on-site machining, field machining, in-place machining or in-situ machining project.
Field System Machining has exceed outage manager expectations for over thirty-three years. Send us your work scope, drawings and photographs and we will quote your project. Don't know where to begin? Download "The Top Ten Things to Know Before Calling the Field Machining Company."
