cutting curves on a vertical mill. feb 01 2021 vertical milling machines in vertical mills the spindle axis is vertically oriented milling cutters are held in the spindle and rotate on its axis typically the spindle can be extended or the table raised or lowered to produce the same effect allowing for plunge cuts and drilling the two kinds
placing the workpiece eccentrically a set distance from the center permits more complex curves to be cut. as with other setups on a vertical mill, the milling operation can be either drilling a series of concentric, and possibly equidistant holes, or face or end milling either circular or . get price
mar 01, 2013 im looking at getting a simple small vertical mill like the sieg x2. hand filing, whilst a useful skill, is seriously tedious. ignoring the vertical (z) plane, how are simple curves cut on a mill? do you have to just walk the cutter along the curve in an x-y step fashion?
