90 Degree Mill Head



In the UI mechanical engineering relies heavily on manual milling operations for manufacturing specific design components. Most can be accomplished with standard milling procedures (i.e. typical stock set-up with x, y and z manipulation), however some require varying tooling set-ups due to their geometry and limitations of the machines.

The 90 degree mill head is a change-over tooling set-up which allows machining part faces which would otherwise be impossible to machine; For instance, a very long part which could not fit in the machine in one or more orientation. The head allows all basic machining abilities, including facing, drilling & tapping, slotting, etc.



Safety
Proper installation of the 90 degree mill head is critical. A few important things should be noted before using the mill head.


 * Miter gears within the mill head REVERSE rotational direction.
 * All standard safety procedures for shop should be used during operation.
 * '''Follow typical milling/drilling procedures (be especially cautious of climb cuts and peck drilling)
 * '''Max recommended spindle RPM = 2300 (noted on mill head as well)

Installation
The 90 degree mill head can be found in cabinet #10, towards the back of the shop. It works much like most collet and other tool installations on the manual mill with only minor additions, noted in the changeover table below. Installation of the 90 degree mill head is not done often, thus careful attention on proper installation is critical. A shop manager and/or mentor is recommended to oversee changeover operations of this type. Video Link
