Our NB Clamshells have really been getting a workout lately.  The picture to the right depicts a large butterfly valve (12’ diameter) with eroded seal captures.  Our 16” machine made quick work of facing each end for new seals.  On the left we have a clamshell that is set up to face standard raised face flanges that are out of tolerance.   Total volume is expected to be between 200-300 flanges on this one job alone.

 On-site repair of MAN B&W diesel generator engine

In-situ machining of crankshaft saddle 

Our customer had a MAN B&W engine block with a cracked bearing saddle.  First we had to submit our repair procedure for approval to the American Bureau of Shipping.  The repair would require our metal locking and on-site machining techniques. We used our portable milling machine to remove the entire damaged area.  We made sure all corners had radii to alleviate stress points.  We then milled a piece of similar material to fit into the pocket.  This piece was “metal locked” into place.  Finally we milled the surface for a finish to meet OEM dimensions.

 20 years of service resulted in significant erosion to the sealing surfaces of 10 flanges on 2 separate decompression chambers for the Mumbai, India based diving vessel Seamec III.  2 field machinists along with our Lloyds of London qualified welder were sent to the Willemstad, Curacao dry-dock for repairs.  Stainless steel weld build up along with facing and o-ring groove cutting were completed on-time and on-budget.

 Propeller blade machining for the Malaga Carrier

Astilleros Braswell International
maintains a large port in Balboa, Panama and they requested emergency on-site machining of 4 propeller blades for their Malaga Carrier. We immediately dispatched crews and equipment to work around-the-clock until complete. Our Climax FF6 Flange Facer made quick work of the job and the vessel was back on-line to meet its scheduled pickup.

When the Laboratory with the largest Laser Bombardment Chamber in the world needed on-site machining, they called MLS. We engineered, fabricated and tested a line-boring machine that was completely encapsulated within a sealed vacuum chamber. Actual machining of 3 separate bores was accomplished inside a Class 1000 cleanroom.

Completed repair to Waukesha 7042 top deck 

A piston failure resulted in a broken block on this Waukesha, which was located 1 hour offshore of Luanda, Angola (Africa). Our team mobilized for an on-site repair which included the attachment of a replacement piece via metal locking followed by on-site machining to finish. A water-tight repair was necessary and achieved. Neither rain, nor snow, nor distance can slow MLS down! 

International Paper called us when their Debarking Drum tire broke completely through. Within hours we had our portable machining equipment and tooling packed and shipped to the job-site in Selma, AL. We worked around-the-clock for 7 days until the job was complete. The repair included a 4" thick masterlock 22" long by 11" wide and additional scab plating to the outside of the tire. Working 50' above the ground in 95 degree heat and high humidity was a challenge, but our crew proved up to the task.

MLS was approached with a very difficult field machining operation. We engineered a unique modular fixture that locates custom Climax portable machining equipment to within 0.001" of desired position. The total operation includes: parting (see picture to immediate left), facing, line-boring, radius cutting and honing to 162 individual parts. Work was completed at 3 separate locations.  The entire project was completed by working 2 crews around-the-clock for 18 straight weeks. 

When this Calendar Roll frame broke, our customer experienced a drop of approximately 30% of their plants output capacity. Within 2 days of notification, we had our crew on-site in Virginia working around-the-clock and straight through the upcoming weekend. Our on-site milling machines made quick work of the masterlock pockets. Please see our Testimonial Page for a glowing report!

Old roll crusher in pieces and in need of rebuild 

Rebuilt roll crusher is ready to go 

Refurbishment of this old Roll Crusher was necessary for our customer to maintain production. We received the unit in pieces and inspected thoroughly for damage. The unit was then sand-blasted and painted. All bearings were replaced and all shafts were reconditioned. Final adjustment of the spring-tensioners was necessary in order for the proper alignment of the crushing rolls. Lastly, we hooked the drive-shaft to our boring mill spindle and performed a "run-in" test.  

Our customer presented us with a scored and worn single-throw crankshaft and a cracked connecting rod. We performed a dimensional take-off on the old crank and machined a new crank out of 4140 stress-relieved material. The connecting rod was repaired via our metal locking technique. All new bronze bearings were inserted and machined to match the new crankshaft and the repaired connecting rod.
