MA-12500HW Horizontal Machining Center

August 03, 2016

The hallmark of the MA-12500HW from Okuma America Corp. MA-12500HW is its ability to provide a good balance of speed and cutting power for machining difficult-to-machine materials, cast iron and aluminum alloys. This makes it well suited for large part aerospace machining. The W-axis allows for a longer tool stroke to machine complex, difficult to reach part features. It has a maximum tool length of 1,100 mm. At IMTS 2016 the MA-12500HW will be shown with the new W-axis option and in skeleton form.  It will feature a cutting simulation of a steel construction frame.

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.

  • alloys

    alloys

    Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.

  • aluminum alloys

    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.

  • inches per minute ( ipm)

    inches per minute ( ipm)

    Value that refers to how far the workpiece or cutter advances linearly in 1 minute, defined as: ipm = ipt 5 number of effective teeth 5 rpm. Also known as the table feed or machine feed.

  • rapid traverse

    rapid traverse

    Movement on a CNC mill or lathe that is from point to point at full speed but, usually, without linear interpolation.
