The difference between planer and milling machine

1. Definition of planer and milling machine

Planers and milling machines are two common metalworking machine tools. Planer is a kind of mechanical processing equipment, mainly used to process the surface of workpieces in engineering and mechanical manufacturing. Its processing principle is to use a single-edged planer to cut along the surface of the workpiece. A milling machine is a mechanical processing equipment that uses a multi-edged tool to cut on the surface of a workpiece.

2. The difference between planer and milling machine

1. Different processing principles
The processing principle of the planer is that the single-edged planer cuts back and forth in a straight line with a slow cutting speed. It is mainly used to process the flat and straight-line surfaces of the workpiece. The processing principle of a milling machine is to use a multi-head tool to perform rotational cutting on the surface of the workpiece. The cutting speed is faster and can achieve more complex and precise processing.

2. Different uses
Planers are mainly used to process planes, grooves, edges and straight-line surfaces, while milling machines are suitable for processing workpieces of various shapes and can process various linear contours, such as edges, windows, shells, etc.

3. Different accuracy requirements
Planers have lower precision and are more commonly used in processing tasks that do not require high precision. Milling machines can achieve higher precision requirements because of their higher cutting speed and cutting force.

4. Different usage scenarios
Planers are generally used for the processing and manufacturing of small and medium-sized parts, such as engine parts, machine tool basic parts and other steel parts; while milling machines are more used for processing workpieces with complex three-dimensional shapes in production, such as automobile reducers and aerospace parts. components and high-precision molds, etc.
3. When is it more appropriate to use which device?

The choice of planer and milling machine depends on the specific machining task and processing requirements.
Planers are suitable for processing straight-line base surfaces, such as large metal sheets, large machine bases and other floors. Complete some routine plane and groove machining at a low cost, or give priority to a planer when the machining accuracy is not high.
Milling machines are suitable for irregular metal processing and precision parts production tasks, such as the processing of mass-produced automobile sheet metal, aerospace engines and other parts, and can effectively improve production efficiency and processing accuracy.
To sum up, planers and milling machines are two different types of processing equipment. Each equipment has its own specific usage scenarios. The selection of equipment should be comprehensively considered based on factors such as processing requirements and workpiece shape.
