DIN179 - Drill Bushings to Liner:Function & Application

DIN 179 is a standard developed by the German Institute for Standardization (DIN) for drill bushings to liner. DIN 179 drill bushings to liner consist of two parts: the drill bushing and the liner. The drill bushing is the part connected to the drill bit, while the liner is the part connected to the workpiece. The connection between the drill bushing and the liner is achieved through threading.

The characteristics of DIN 179 drill bushings to liner are as follows:

 

* They have high rigidity, preventing drill bit deformation.

* They have excellent guiding properties, enhancing drilling accuracy.

* They provide good protective capabilities, safeguarding the workpiece's surface.

 

DIN 179 drill bushings to liner find wide applications in:

 

* Mechanical manufacturing

* Automotive manufacturing

* Aerospace

* Metallurgical industry

* Electrical industry

 

The usage of DIN 179 drill bushings to liner is as follows:

 

1. Mount the drill bushing onto the drill bit.

2. Install the liner on the workpiece.

3. Connect the drill bit with the liner.

4. Begin drilling.

 

DIN 179 drill bushings to liner are crucial mechanical components that have widespread usage in machining.

 

Here are some considerations regarding DIN 179 drill bushings to liner:

 

* Select the appropriate specification of drill bushings to liner.

* Properly install the drill bushings to liner.

* Follow the instructions when using drill bushings to liner.

 

By correctly choosing, installing, and utilizing DIN 179 drill bushings to liner, you can improve drilling quality and extend the lifespan of drill bits.

 

Specifically, the main differences between DIN 179 drill bushings to liner and DIN 176 drill bushings to liner are as follows:

 

* **Materials**: DIN 179 drill bushings to liner are commonly made of carbon steel, alloy steel, and stainless steel, while DIN 176 drill bushings to liner are mainly made of carbon steel and alloy steel.

* **Strength**: DIN 179 drill bushings to liner have strength grades of 4.6, 5.6, 6.8, 8.8, 9.8, 10.9, and 12.9, while DIN 176 drill bushings to liner have strength grades of 4.6, 5.6, 6.8, 8.8, 9.8, and 10.9.

* **Accuracy**: DIN 179 drill bushings to liner have accuracy grades of H7, H8, H9, whereas DIN 176 drill bushings to liner have accuracy grades of H6, H7, H8.

 

Depending on specific application requirements, you can choose the appropriate DIN 179 drill bushings to liner."
