There are two types of boring mills, horizontal and vertical. On a horizontal machine the spindle is mounted horizontally and on a vertical machine the spindle is mounted vertically. The main difference between the two is that on a horizontal boring mill, the workpiece is stationary and the tool turns, while on a vertical boring mill, the tool ...
The spindle speed and feed rate were optimized as 270 rpm and 0.073 mm/rev. respectively through DFA and 468.85715 rpm and 0.13684 mm/rev., respectively through GA to minimize the responses.
Mills are classified on the basis of the position of their spindle. The spindle operates in either a vertical or horizontal position. The amount of horsepower the mill is able to supply to the cutter is also often important. Mill Construction; The vertical milling machine is made up …
The horizontal axis spindle carrier 14 is disposed such that when moved to the lower extreme of its vertical travel, the vertical axis spindle carrier 15 may have essentially all of its normal vertical movement, and as such can address the workpiece for milling operations in the usual manner.

The experiment was conducted with four spindle speeds (1400, 2100, 2800, and 3500 rpm) in dry machining conditions. The experiments were conducted on a CNC-HMT-type-vertical milling machine using a cBN coated end mill ().The targets of sustainability factors like surface roughness, material removal rate, power consumption, tool wear, and tool life are examined.
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 of vertical mills are bed mills and turret mills.
A wide range of spindle speeds combined with infinitely variable feed rates makes cutting ferrous and non-ferrous metals highly efficient.
