What are the advantages of a horizontal boring mill?
The biggest advantage to a horizontal boring mill is the expanded size limits. Most spindles extend out from the headstock of the boring mill, allowing them to reach into the workpiece for deeper operations. If necessary, the workpiece can be removed, pivoted, and re-mounted for greater reach.
What is a vertical boring mill?
For smaller workpieces, vertical boring mills function almost exactly like a vertical lathe or turning center. The workpiece mounts to a chuck and rotates rapidly, while the cutting tool is stationary. The cutter is lowered into the rotating workpiece, using the motion of the part to bore out the hole.
What are the parts of a boring bar?
There are three critical parts to any boring bar: the spindle, the anchor, and the insert. The anchor is straightforward – it’s the point where the bar connects to the body of the mill. The spindle rotates under power, turning the tool and creating the necessary force to cut into the workpiece. The indexable insert is the extendable part of the spindle, used to slowly propel the cutter into the workpiece.
