The Vertical Milling Machines consist of the milling cutter, spindle, column, over-arm or top slide, table, Y-axis slide, knee and the base. In this type of milling, the spindle of the axis is leaning vertically. The milling cutters were held to the spindle and then rotate within the axis. Spindles could be normally extended or tables are can be able to be raised or lowered, and allowing similar effect that permits the plunge to cut and drill.
2 Subcategories of the Vertical Milling
Bed-mill – the table is allowed to move perpendicular only to the axis of the spindle, as the spindle is moving parallel in its personal axis. Another thing to remember is the lighter machine known to be the mill-drill. It is most popular to the hobbyist because of its smaller size and it is cheaper to acquire. Though, this is in lower quality compared to the other types of the machine.
Turret mills – it is usually smaller compared with the bed-mill and believed to be the more versatile type. With the turret mill, spindle will remain in a stationary mode during the cutting procedure but the table will be moving perpendicular and parallel to the axis of the spindle to be able to accomplish the cutting operation.
Horizontal Milling Machines – they are consisting of the base, knee, column, table, X-axis, over-arm and the arbor which is attached to the spindle. The horizontal milling is the same type as the x-y table thought the cutters were placed on the horizontal arbor diagonally to the table. Majority of the horizontal millings do also features the +15/-15 degrees of the rotary tables which is allowing the mills to its shallow angles.
End-mills and other types of the tools that are available to the vertical milling can also be used in horizontal mills. The real advantage is lying to the arbor-mounted cutter that is called the side and the face mills. They prefer the cross sections rather than the circular saw, and they are basically wider but smaller in diameter. Since the cutters possess fine support from arbors, heavy cuts are able to be taken.
Plain mills were utilized for shaping flat surfaces, and several cutters can be ganged all together at the arbor to be able to mill some complex shapes of those planes and slots. These special cutters will then able to cut the bevels, radii, grooves or any other section that they desire. However, these special cutters are more expensive compared to the usual mill. Simplex mill is consisting of one spindle ant the duplex millings have two. Added advantage of this horizontal milling is the easiness of cutting gears.
