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.
Benefits of VMCs over HMCs
Vertical machining mills may not be as versatile and as rigid the horizontal ones, but they can be very handy when simple processing of small parts is required. They are easier and faster to set up and get the work started and machinists can work in very tight tolerances compared to the larger, horizontal mills. They also take much less space and cost way less. Last but not least, vertical mills feature a retractable quill that can be used for accurate milling and especially boring processes.
Typical Uses
Depending on the expertise and the available cutting heads of various types, vertical machining centers can be used for a set of metalworking tasks. Here is a list with the most prominent applications of this unique machine:
1. The most standard type of milling done with the vertical machine is face or slab milling. This is basically the milling of flat surfaces with the workpiece being mounted parallel to the working table. Using this simple technique, machinists can create indentations, flattening, and leveling.
2. Similarly, if the workpiece is mounted in an inclined way, the slab milling is transformed to angular milling. This helps with the materialization of jointing dovetails.
3. Going a step further, machinists can use the straddle milling technique that basically utilized two milling heads that are cutting parallel to each other. This is done by fixing the cutters on the same arbor. Using this technique, VMCs can mill hexagons on bolt heads or open parallel grooves on flat surfaces.
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. Finally, vertical mills can drill and bore holes thanks to their adequate speed and torque values, as well as their retractable quill that helps in the accuracy part of the process.
