“ We machine flanges for wellheads, connector manifolds, and subsea components used in oil production,” says Steve Eldridge, shop superintendent for Sun Manufacturing in Houston. On a subsea flanged spool of 4130 steel, Sun was drilling eight inches of depth using pecking cycles and was feeding at about an inch per minute using a spade drill.“With the KSEM PLUS™, we were able to drill the eight inches of depth and the feed was 10 times faster.” What could have taken more than eight hours to complete 24 holes was accomplished in 38.4 minutes.“The KSEM PLUS paid for itself on the first part.”
