Alignment of the Milling Machine Table In order to produce good work when straddle-milling on a singlespindle milling machine, it is necessary to have the table travel exactly at right angles to the axis of the spindle. Should it not do so, it will be necessary to either scrape the saddle or swivel the head to get the alignment.

Straddle Milling. When two or more parallel vertical surfaces are machined at a single cut, the operation is called straddle milling. Straddle milling is accomplished by mounting two side milling cutters on the same arbor, set apart so that they straddle the workpiece. The diagram below illustrates a typical example of straddle milling.
