Milling is one of the most common machining processes. It can be used to machine a variety of materials such as metal, wood and plastic, but the best milling machine for a specific project depends on the complexity and requirements of the specific design.
Vertical milling machines have a vertical spindle axis. There are two common types of vertical mills. For the first type – a bed grinder – the material is placed on a bed that can move back and forth horizontally, while a tool attached to a spindle can be guided up and down. Another type—turret milling machines—includes a fixed spindle and a bed that can move vertically and horizontally to position the material.
The basic mechanism of vertical milling makes it particularly suitable for drilling and plunge milling. In fact, the movement of the machine is often reminiscent of a standard drill press.
Vertical milling offers the following advantages:
Due to the openness provided by the orientation, vertical milling machines provide the user with greater visibility. This is useful for slower projects that require extra attention to detail.
Since vertical milling is widely used in machine shops, the machines themselves are more readily available and cost significantly less than horizontal milling machines.
The CNC control of vertical milling machines is very user-friendly, and the widespread availability of machines means it is easier to find a workforce with the right skills. The work done on a vertical mill is also usually simple and doesn’t require any special fixtures.
CNC vertical milling machines ensure precise cuts and reduce the risk of human error in manual machines.
