Milling machines cover a varied range of operations. In the manufacturing industry, it is an integral part and some called it the backbone of the manufacturing industry. The machines are categorized mainly under two types. They are Horizontal milling machine and Vertical milling machines. Then there is further classification. And, there are obviously various parts or components of a milling machine.
Here, we will discuss the parts of a milling machine.
- Column & Base
There has to be one component that supports other parts of a machine. The duo of column and base play that role in a milling machine. The task of a column is to contain an oil reservoir and a pump which help in lubricating the spindle. This column is rested on the base. It contains the coolant reservoir and a pump and a pump. It is used when there is an operation of machining in which coolant is required.
The casting that supports the saddle and table is called a knee. the knee encloses all the gear mechanism. It is merged with the column. It is adjusted with to the column with an elevating screw that makes the knee move up and down. A hand lever or power lever is used to move the knee.
- Saddle and Swivel Table
The table is supported by a saddle that is on the knee. it is parallel to the axis of the spindle. It slides horizontally on the dovetail that is on the knee. The swivel table is attached to the saddle.
- Power Feed Mechanism
As mentioned earlier the contains all the gear mechanism. The power feed mechanism that the knee is responsible for is used to control the longitudinal, transverse, and vertical feeds.
The rectangular casting present on the top of the saddle is the table. It holds the work-piece in T-slots present in it and also holds the work holding devices.
The shaft or spindle is fitted to hold the cutting tools and drives of the milling machine.
- Arbor Support
The arbor support is fastened by an overarm. The outer end of the arbor is aligned with a spindle. This alignment is controlled by the arbor support.
