Vertical milling
In vertical milling, the 3-axis milling table serves as the work surface, and the spindle is mounted under the arm.
When a vertical turret mill is used, the spindle may be fixed. In this case, the table moves in both the X and Y axes. On the other hand, if a bed-type vertical mill is used, the table moves only in the X-axis direction. The spindle moves in the Y-axis direction along the longitudinal direction of the arm.
Horizontal milling
In horizontal milling, the spindle moves horizontally instead of vertically, and all other components are the same as in vertical milling. In general, horizontal milling machines are better suited for heavy or long machining operations. They are also suitable for parts where a large amount of material needs to be removed because chips fall off the part and the cutter.
Plain milling
One in which the axis of rotation of the cutting tool is parallel to the surface of the workpiece. The outer circumference of the cutter has teeth to perform the cutting process. Narrow and wide cutters are used. This allows for a deeper cutting depth and a larger surface area to be machined. There are course cutters and fine tooth cutters. Course cutters have slower cutting speeds and faster feed rates, while fine tooth cutters are the opposite. This allows for more precise machining.
Angular milling
This is a milling process in which the axis of rotation of the cutting tool is at an angle to the surface of the workpiece. Single angle milling cutters can produce more angular shapes such as grooves, serrations, and chamfers.
Form milling
Form milling is ideal for milling operations that involve many irregular surfaces. Examples are contours, outlines, edges, and parts with curved or flat surfaces. Use milling cutters or milling cutters, for example, concave cutters or rounded corner cutters, which are specialized for specific applications. For hemispherical or semi-circular designs, or similarly complex parts, form milling techniques are useful.
There are several types of CNC milling, each with its own advantages and disadvantages. The most common types are:
Vertical milling machines
Vertical milling machines have the spindle on the y-axis, meaning that the table moves up and down. These machines are generally more versatile than horizontal milling machines because they can be used for a variety of different operations, such as drilling, reaming, and tapping. However, they are not as good at heavy cutting operations.
Horizontal milling machines
Horizontal milling machines have the spindle on the x-axis, meaning that the table moves side to side. These machines are better suited for heavy cutting operations than vertical milling machines.
Bridgeport milling machines
Bridgeport milling machines are a type of vertical milling machine. They have the spindle on the y-axis and the table moves up and down. Bridgeport milling machines are very versatile and can be used for a variety of different operations.
CNC milling machines
CNC milling machines are computer controlled versions of traditional milling machines. These machines are more precise and can be used for more complex operations than traditional milling machines.
5 axis milling machines
5 axis milling machines are the most versatile type of milling machine. They have the ability to move the table in five different directions, allowing for operations that would be impossible on a traditional milling machine.
No matter what type of milling machine you choose, it is important to find one that is well built and from a reputable manufacturer. This will ensure that your machine will last for many years and will provide you with accurate results.
