Okuma's MA-12500H horizontal machining center provides a good balance of speed and cutting power for machining of aluminum alloys, cast iron and difficult-to-machine materials. This makes it well suited for large part aerospace machining. The MA-12500H is the machine of choice for building lathes at the Okuma DS1 plant in Oguchi, Japan.
Built on an integral bed and base, and designed with reinforcing ribs for increased stability and load carrying capacity, the MA-12500H incorporates Okuma's exclusive Thermo-Friendly concept to achieve maximum thermal stability and accuracy. Standardly equipped with a 50 taper 6,000 rpm, 60/50 horsepower spindle, it is also available with either a 12,000 rpm wide range spindle or 4,500 rpm heavy duty spindle.

Related Glossary Terms
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- aluminum alloys
Aluminum containing specified quantities of alloying elements added to obtain the necessary mechanical and physical properties. Aluminum alloys are divided into two categories: wrought compositions and casting compositions. Some compositions may contain up to 10 alloying elements, but only one or two are the main alloying elements, such as copper, manganese, silicon, magnesium, zinc or tin.
