Product category: Centrifugal casting machines
These horizontal centrifugal casting machines are used to babbitt line bearing shells. The machine utilizes two face plates. They have many holes accurately drilled so that three round centering bosses of the proper diameter can be screwed into the proper holes. These diameters are arranged so that the outside of the bearing shell or fixture holding the shell will be aligned by the three bosses. The idler face moves over a distance of four or six inches to clamp and unclamp the bearing shell. When the shells to be babbitted have odd configurations, the entire sheII and fixture assembly should be carefully balanced.
Vertical centrifugal casting machinery spins parts about a vertical axis. Parts are commonly of shorter height than diameter. The great benefit of spinning about a vertical axis is that practically any size and shape of casting can be spun about a vertical axis. Common castings poured in vertical machinery are rings and ball valve balls. Generally, vertical machines are divided into two categories, Stand-Alone machines, which can be easily added into a foundry with limited foundation work and Pit Mounted machinery, which are mounted below floor level and require a foundry to do substantial foundation work.
The question commonly asked is, can a casting that is commonly poured statically be poured vertically, even if it is a nonstandard shape. The answer is yes. Why pour castings in a vertical spinning machine that can be poured statically? The primary reasons are to obtain better quality castings, to produce castings more economically and to cast a part that cannot be satisfactorily cast statically. Reduction in cleaning room costs and higher yield are common reasons why foundries pour castings using vertical centrifugal casting machinery. Steel castings that are statically poured with a yield of 40 to 55% can be centrifugally cast with a yield closer to between 65 and 85%.
Nathan Janco founded Centrifugal Casting Machine Company in 1940. "Nat was universally acknowledged as a pioneer in the field of casting machine design and one of the foremost authorities on the subject of centrifugal casting. During WWII, Nat was the centrifugal casting expert on the U.S. War Metallurgy Committee. Nat held several U.S. patens and was the designer of numerous horizontal, vertical and face-plate machines, as well as special purpose machines for high production. Nat pioneered the centrifugal casting of plastics, magnesium sludge, uranium and titanium, in addition to centrifugal vacuum casting. He authored the book Centrifugal Casting (Dynamic) and wrote articles which appeared frequently in the American Foundrymen's Society' Transactions." Nathan Janco passed away in 2006 at the age of 95.
In 1980 Janco sold Centrifugal Casting Machine Co., Inc. to Tom McKee a Tulsa businessman. McKee worked with a sales team and a group of engineers to grow CCMCO into a world renowned company. Under McKee, CCMCO expanded into China and into high production markets such as ductile iron pipe, soil pipe and cylinder liners. Und McKee, company was also ISO 9000 certified. Tom McKee passed away in 2003 and CCMCO continues to operate as a family owned business. Sue McKee, Tom's widow is President and two of his three children are active in the company.
