Vertical machining mills are one of the oldest and most widely used tools in workshops around the globe. They feature a rotating milling cutter that is positioned on the top of the machines in a vertical orientation, and a workpiece table that is where the item is fixed onto and is also movable through hand wheels and levers.
VMCs are mostly found in two distinct types that are able for different machining possibilities. The first one is the "bed mill" while the second type is the "turret mill". The main difference between the two is that the first one allows the perpendicular movement of the workpiece table while the later also supports movement along the axis that is parallel to the cutting head.
Advantages over Horizontal Centers
Vertical machining centers are much faster and easier to set up compared to the larger and more heavy duty horizontal millers. This makes them ideal for the processing of smaller parts, or for performing less demanding metalworking tasks. In addition to this, vertical mills can perform much more intricate work at very tight tolerances, something that is practically impossible with most horizontal centers. Another significant difference is the retractable quill that is available in VMCs and helps in the accurate boring of holes.
Common Uses
Vertical Machining Centers can help machinists perform a wide range of tasks in the metal processing spectrum. Ally to this versatility is the rich collection of special cutting heads, offset boring heads and rotary tables that can be added to the machine in order to perform one of the following tasks:
1. Slab or face milling is done to level or flatten a surface and is a simple process when using a VMC, as mounting the workpiece normally on the worktable is enough to get it started.
2. In a similar way, if the workpiece is silently mounted, the milling is performed in an inclination. This angular cutting can produce dovetails for joints.
3. For even more demanding and complex results, there is the straddle milling that involves two parallel milling cutters mounted on the same arbor and separated by an exact spacing. This makes the simultaneous cutting of two points possible, which is very useful when in need to mill hexagons of bolt heads for example. This will also need the addition of a rotary index table as the milling arbor is not rotatable.
4. Vertical Machining Centers are also very useful for forming the rough edges using convex cutters. These cutters can achieve high fidelity grooves, concaves and corner rounding.
5. Using special key-slot cutting heads that boast certain diameter and width, machinists can mill keyways along the axis of shafts. These keyways can have different shapes such as squares or round-end for example.
6. By combining the straddle milling and the angular cutting techniques, skilled machinists can produce high precision splines and gears suitable for very low tolerance applications with the minimum gamble.
7. Last, there is the obvious ability to drill holes using a vertical milling machine. The retractable quill offers tremendous help in this endeavor as it serves for the setting of the boring center.
