Application Description

The work-pieces comprise mostly of bodies from ram and annular type BOPs, as well as their related components. Swing diameters are up to five feet, and heights reach up to five feet also. The materials range from mild steel alloys to Inconel. Machining operations are a combination of roughing and finished turning and boring. The work-pieces are held in four-jaw chucks. and specialized fixtures.

Momentum Machines Employed

This installation uses an MVL-16 machine. MVL-16 models feature 240mm (9.44″) rams, 1,600mm (63″) diameter tables, 2,000mm (78″) swing, and 10,000kg  (22,000lb) load capacity.

Results Achieved

The MVL has provided rock-solid production since 2015, showing the durability required to produce heavy work-pieces and survive in harsh oil and gas industry manufacturing environments.

Customer Perspective

‘In the first year of the MVL’s operation, we had an ‘operator-induced event’ which resulted in a 3″ boring bar being rapid-traversed straight into the work-piece. This totally sheared off the boring bar, but the work-piece looked salvageable, and the customer was expecting us to ship it to them that night. Panicked, we called the distributor to come to realign and, if necessary, repair the MVL so that we could finish the part. After they did an evaluation and test cut, we found that the machine was still perfectly aligned and there wasn’t a thing wrong with it. We were amazed. That sucker is built as tough as they come. For a while, we kept that sheared-off boring bar to show customers they would bring to visit our installation.’
