Milling Machine Parts and Functions

Milling Machine Parts and Functions The milling machine is an essential asset in the manufacturing industry. The primary role of milling machines in the industry is to help a manufacturer to get milled parts. It is essential for milling operations such as thread, angular, and gear milling. Industry highly demands such a machine to remove metal from a workpiece and get the desired shape with the help of a cutter.

It works well on flat, irregular, and rough surfaces. A milling machine can operate by a computer numerical control system. You must understand the function of different parts in the milling machine. It is an efficient tool for mass and small production. The machine is suitable for making different workpiece in several shapes like surface, groove, plane and gear.

Knee: The gearing mechanism can enclose within the knee and fasten to a column by dovetail. It may gain immense support from a vertical positioning screw. The elevated screw is ideal for regulating the knee up and down and lowering the liver with power and hand feed.

Base and column: The base and column support other parts of the milling machine. The oil reservoir and pump in a column are responsible for a lubricating spindle. A column can stay on the base and manage the coolant reservoir. A pump delivers coolant in machining operation.

Power feed mechanism: The machine's power feed mechanism is an excellent way to manage transverse, vertical and longitudinal feed. A feed selection lever can place to specify on the feed selection plate for a specific rate feed. Improve transverse, vertical and longitudinal speed is mandatory when a rapid traverse lever is used. A lever allows the operator to quickly align and position work and obtain milled parts.

Swivel and saddle table: The saddle is present on the knee and support table very much. Saddle slide on horizontal dovetail may parallel to the spindle axis. On the other hand, a swivel table can attach to a saddle.

Table: The table acts as rectangular casting present on the saddle top. It is the best option to hold work and work-holding devices. Several T-slots can hold work and devices. Operators may operate by hand or power.

Spindle:

The primary function of the spindle is to hold and force the cutting tools of the machine. The spindle mounts on the bearing and brings support to a column. Parts may drive by an electric motor through a gear train on the column. The spindle face lies near the table and maintains an internal taper machined. Two keys are available at the front face to deliver an optimistic drive for the cutter holder or arbor.

Arbor support: Arbor support can be cast with bearing supports outer end. Part's function is to align the outer end of the arbor with the spindle. Arbor support avoids the outer end of arbor springing in cutting operation. Generally, two types of arbor supports are present in the milling machine.

Ram: Ram serves as overhanging arm in the vertical milling machine. One end on the ram can mount on the column top. Milling heat can attach to another.
