  The Cincinnati Gilbert Five Axis Horizontal Boring Mill (S.N. A-4444-JRM) was purchased in 1984 to support NASA Lewis Research Center in its' leadership efforts of being a center of excellence in turbo machinery. It has a five foot cube work piece capacity and full five axis contouring capability. The machine tool has a 60 inch travel table with a built in 60 inch diameter turntable. The 27 gear multi speed head has a 5 inch spindle with 36 inches of travel and is mounted on a column which travels 24 inches horizontally and 60 inches vertically. A fifth axis 48 inch diameter turntable is mounted on the 60 inch turntable to attain full 5 axis articulation of the work piece. All axes are controlled by inductosyn scales for 0.0001 inch and 0.001 degree resolution movement. This combination of size, resolution, and articulation make this machine tool very unique and singularly capable of machining hardware for turbo machinery and other large complex accurate hardware. The spindle clock shows less than five man years of use so there is very little to no wear on the machine tool. A special foundation is required to accommodate the two main runway tables and all of the support hardware such as the spindle oil refrigeration unit, coolant reservoir, and the extensive relay and servo amplifier cabinets.

    Horizontal boring mills come in two types - Floor type and table type.  Both will have a spindle that moves towards the part on a plane horizontal to the floor.  Most modern table type boring mills will be smaller tables with less weight capacity, but may have a rotation axis that allows them to turn and index like a lazy susan.  These are what the workpiece is fixed to.  Floor types are generally for larger pieces.  Some of them can run on rails that take up a whole room.

    Another type of boring mill is the vertical boring mill, which is generally the same thing as a vertical turret lathe.  The difference is that the whole base of the machine will normally function like a chuck, rotating the part fixed to it to be turned (or machined in more modern CNC machines) and cut.

    CNC Horizontal and Vertical boring mills cost more money, but has modern controls and programming.  The pricing difference can be enormous and will often not be justifiable if the customer is not a production or very high margin shop.  If manual, do they need a D.R.O. (Digital Read Out)- a DRO shows the position and if so, 3 or 4 axis?
