The processing method of ordinary milling machine

There are various processing methods for ordinary milling machines, and according to the different processing objects and requirements, the following common processing methods can be used:

1. Plane milling

Definition: Planar milling is one of the most commonly used machining methods on ordinary milling machines, which cuts material on the surface of the workpiece using milling tools to flatten the desired planar shape.

characteristic:

High milling accuracy and machining efficiency.

Multiple planes can be processed simultaneously, making it easy to control and adjust during the processing.

Suitable for machining workpieces with different precision requirements.

2. Contour milling

Definition: Contour milling is a common part machining technique that achieves precision machining of workpiece shapes by moving milling cutters of different shapes and the workpiece surface relative to each other.

Category:

Closed contour milling

Open contour milling

Hole wall milling, etc

characteristic:

Suitable for processing complex workpieces.

It has the advantages of high precision, high efficiency, and high repeatability in machining.

3. Drilling

Definition: Drilling is a common method of machining workpieces on ordinary milling machines, which involves cutting holes of the required size and depth on the surface of the workpiece using a drill or milling head.

Category:

Ordinary drilling

reaming

Boring

Core pulling, etc

characteristic:

High precision requirements and fast processing speed.

Can meet different types of hole processing requirements.

4. Coordinate milling

Application scenario: When complex curves or arcs need to be machined, coordinate milling can be used.

Operation steps:

Draw a process dimension diagram based on the set coordinate system.

Calculate the dimensions based on the coordinates of each section in the diagram.

Fix the tool at the intersection of the workpiece’s arc and plane, and perform machining by moving the tool.

Attention: During the machining process, it is necessary to accurately calculate the coordinates and pay attention to the tool setting status to ensure machining accuracy.

5. Other processing methods

In addition to the common machining methods mentioned above, ordinary milling machines can also perform other machining operations according to specific needs, such as boring, expanding, reaming, tapping, etc. These processing methods usually require the combination of different cutting tools and process parameters to achieve.

Precautions during processing

Safe operation: When operating the milling machine, it is necessary to strictly follow the safety operating procedures and wear safety protective equipment.

Tool selection: Choose the appropriate tool based on the material, shape, and precision requirements of the workpiece being processed.

Process parameter setting: Set reasonable process parameters based on processing requirements and machine performance, such as cutting speed, feed rate, cutting depth, etc.

Workpiece installation: The workpiece must be installed firmly to avoid a decrease in machining accuracy or damage to the machine tool due to looseness of the workpiece.

Processing inspection: During the processing, the dimensions and surface quality of the workpiece should be regularly checked to promptly identify and address any issues.

In short, the processing methods of ordinary milling machines are diverse and flexible, which can meet the processing requirements of different accuracies and shapes. Careful operation and strict adherence to safety regulations are required during the processing to ensure processing quality and personal safety.
