Milling machine guide

What is a milling machine?

Under one milling Machine (colloquially also known as a milling machine) means an exciting machine tool. This rotary cutting tools contribute to the milling Machine Cutting off material from a workpiece in order to bring it into the desired shape. Thanks to at least three feed directions, which are the router available, thus also complex spatial body can be produced. This can be complex parts such as e.g. To be gears or engine blocks. But also ordinary and simple work, such. the rubbing of holes or drilling, can with a milling Machine be done.
Identification of a milling Machine are their at least three axes of motion. These are assigned to the tool or workpiece carrier. This milling tool moves through the material and wears it off with the help of cutting. A simple one milling Machine is equipped with a manually and horizontally movable machine table and a milling head, which moves horizontally. The milling cutters of the movable milling head can also be extended manually with the help of the quill. In modern milling machines have swivel and rotatable tool or workpiece holders and their axes of motion are assigned differently.

How are milling machines generally structured?

Even though the models differ greatly thanks to the wide range of processing cases, they also have a large number of similarities:
1. machine standand frame:
The frame is the lowest assembly on a milling machine and must carry all components. Depending on the weight of the machine, this is set up and adjusted on a special foundation. On many models, the machine stand and frame form a unit to which the guides are attached. This type of model is also known under the name Monoblockmaschine. This is more suitable for small and medium sizes. Their advantages include a high dynamic load capacity, ergonomic operation and a small machine footprint. From a certain size, the production and transport costs can no longer be justified. Larger machines consist of a steel construction and are modular. The hand-operated machines have gearbox and motor integrated in the frame.
Second bedand machine table:
Whether the milling machines are clamped on a bed or a machine table depends entirely on the size of the respective milling machine. In conventional milling machines, the machine table is designed in the form of an angle table. This hangs on the cross slide and the console is installed in the guides of the machine stand. The cross slide moves horizontally and the console vertically. Horizontal milling machines are also often found before cross tables. These allow the table to move in a third axis. In turn, angle-controlled turntables are ideal for all-round machining and demanding turning operations.
Bed milling machines are suitable for cutting bulky and heavy workpieces. In this case, the bed lies in any position at all vertices. This prevents bending. But since the consoles tilt sideways in the end positions, geometric inaccuracies may arise.
3. Milling head with main spindle:
The main spindle is stored in the milling head, sometimes even with integrated quill. Conventional milling machines usually have a vertical work spindle with steep taper receptacle and manually extendable quill. For a safe, fast and automatic change of the tools have CNC milling cutter heads with Steep shaft or hollow cone and a hydraulic tool clamping system.
4. Feed:
A main drive or servomotors generate the feed movement of the individual axes and transfer these by means of thread drives to the sled, In order to prevent the workpiece during the run-in milling not in the Toola play-free run of the shoots is important. Whereas older milling machines can still be cranked by hand, more and more hydrostatic screw drives and linear drives with roller-bearing guides are gaining ground in newer models.

Differences become milling machines after:
1. Intended use and design in console milling machines, bed milling machines and special milling machines.
2. Position of the milling spindle in vertical and horizontal milling machines.
3. Type of control in numerically and mechanically controlled milling machines.
