Column and Knee Type Machines
They are the most popular commercial milling machines utilized for general industry work. The two types differ mainly by their functions and characteristics, although both employ the same methods of turning steel into components.
Difference Between Column and Knee Milling Machines
With the exception of a few differences, both types of machines are similar in working. They have the basic design that allows them to accept and process either horizontally or vertically cut metal sheets. Although they can produce different designs, they usually operate on the same basis and basic operations. As for features, both types of equipment provide excellent finishes because their tools and powder-coated finishes are commonly preferred. They also have commonly preferred feature safety features such as universal mounting capability and interlocking feed systems. Also, both types of equipment have feed systems and rails to allow for the safe assembly and disassembly of units.
Features of Milling Machines
The main differences between the two machines can be identified by their main function. Vertical feed machines are primarily used to move horizontally cut pieces from one end of the table to another. In comparison, horizontal milling machines are designed more for heavy-duty applications where fast, accurate results are essential. Some examples include drilling, counterbores, and drawing. In most cases, these machines require their own platforms for easy placement and transport.
These types of machines can also be classified according to their drive systems. Horizontal machines use a chain or series of gears for the vertical milling process. The main benefits of these types of machines are that they provide high-quality results and are less expensive than the other designs. They are also easy to assemble and maintain.
The Bottom Line
The vertical types use a screw thread for the operation. Their major benefit over the horizontal version is that they are cheaper, but the major drawback is that they cannot be moved along the table. The most common type of motor used in these machines is the roller type. A universal machine is mostly used when there is a need for a standard size cut and because they are not customized.
Cylinder-driven horizontal units are usually preferred for the fast, accurate turning functions that are required by the industry. The tabletop of these machines is usually made from a single piece of material and powered by two or more screws. Universal units are mainly used when there is no need to change the speed of the screws during the operation. They are mainly used in table saw tables or in other industrial applications where the size and shape of the workpiece is a limitation. These are mostly used in home applications where speed and accuracy are not critical.
