for precision machining of wear parts for couplings, well service valves and valve seats, pump valves and seats, and pistons and other parts to 20" (508-mm) diameter. Accord- ing to Bill Gore, regional manager-North America, these parts are typically made from metals like 8620 alloy steel forgings or saw- cut bar and have to meet the operat- ing and performance requirements associated with abrasive and corrosive environments found in oil field and fracking operations.
“One of the challenges that our oil field customers face on a daily basis is the need to change over within families of parts.”
“One of the challenges that our oil- field customers face on a daily basis is the need to change over within families of parts. The ANW machines are versatile and able to handle changeover for families of parts, which may consist of tris, quads, or quints, fracking pumps with three, four, and five pistons, in different diameters for different sizes of valves and seats,” said Gore. “It isn’t unusual for end users to mix and match different brands of com- ponents based on their preferences. They can change internal components to match the different conditions of fluids, media, and chemicals that they are required to pump,” said Gore. “For downhole applications, we have developed a cell for turning the OD and ID of popular 5½ and 7" [140, 178-mm] semi-premium couplings. It features an ANW 5000 twin-spindle horizontal machine, with a lot of Z-axis travel to machine both sides of the part.
Internally, there’s extra travel in the Z stroke to accommodate long-reach boring bars. We leave the bore semi-finished with enough stock so that they can be threaded on another machine,” said Gore.
