Our services

On-site machining of flange faces is critical in maintenance and shutdown work. Portable flange facers are clamped or bolted to the flange and machine the face in place.

• ▸Damaged flanges (corrosion, pitting, dents)
• ▸Warped or out-of-alignment flanges
• ▸ID-mounted (½″ to 12,000 mm)
• ▸OD-mounted when bore access is restricted
• ▸Pneumatic, hydraulic and electric servo drives
• ▸Spot-facing of bolt circles
• ▸Re-cutting of seal grooves such as RTJ

High-precision CNC machining directly at your facility – turbines, engine blocks, pressure vessels and heavy industrial equipment are machined without dismantling.

• ▸Face milling (turbine housings, engine foundations, flanges)
• ▸Bolt milling without thread damage
• ▸Contour milling of complex shapes
• ▸Cylinder-liner landing repair
• ▸Thread milling in all dimensions
