The principal parts of a milling machine include:
1. Base: The base is the foundation of the machine and provides support for all other components. It is usually made of cast iron or steel and is designed to absorb and distribute the vibrations generated during the milling process.
2. Column: The column is a vertical structure that supports the other components of the machine, such as the spindle and the table. It is usually made of cast iron or steel and is designed to provide stability and rigidity to the machine.
3. Spindle: The spindle is the rotating shaft that holds the cutting tool. It is driven by a motor and is responsible for rotating the tool at high speeds to remove material from the workpiece.
4. Table: The table is a flat surface that supports the workpiece during the milling process. It can be moved in different directions to position the workpiece under the cutting tool. The table may also have T-slots for securing the workpiece using clamps or vises.
5. Knee: The knee is a vertical structure that supports the table and allows it to be raised or lowered to adjust the depth of cut. It is usually mounted on the column and can be moved manually or using a power feed mechanism.
6. Saddle: The saddle is a horizontal structure that supports the table and allows it to be moved back and forth along the length of the table. It is usually mounted on the knee and can be moved manually or using a power feed mechanism.
7. Overarm: The overarm is a horizontal structure that supports the arbor or spindle and allows it to be positioned at different angles. It is usually mounted on the column and can be adjusted to accommodate different types of milling operations.
8. Arbor: The arbor is a shaft that holds the cutting tool and is driven by the spindle. It is usually mounted on the overarm and can be changed to accommodate different types and sizes of cutting tools.
These are the principal parts of a milling machine that work together to perform various milling operations on workpieces.
