Drill Bushings to Liner, Explaining DIN 179 Standard

To overcome the disadvantage of fixed drill sleeves that cannot be replaced when worn, interchangeable drill sleeves were developed. Standard interchangeable drill sleeves have a flange with a milled shoulder, and the stepped head of the drill sleeve screw is pressed against the shoulder to prevent the interchangeable drill sleeve from rotating. By removing the screw, the interchangeable drill sleeve can be taken out. When using a drill template with interchangeable drill sleeves, a liner should be specially installed at the location of the interchangeable drill sleeve, and the interchangeable drill sleeve is placed in the liner. This avoids damaging the drill template when replacing the drill sleeve. The practical function of interchangeable drill sleeves is the same as that of fixed drill sleeves, and they are only used for the drilling process.

 

Interchangeable drill sleeves are used when working with larger batches to facilitate quick replacement when the drill sleeves wear out. Interchangeable drill sleeves are essential in mechanical machining and can be used for rapid hole drilling. From an internal enterprise management perspective, the widespread use of drill sleeves reduces labor requirements, optimizing internal resources and improving operational efficiency.

 

DIN 179 is a German standard that specifies the design and specifications of drill bushings used for guiding and positioning. DIN 179 is commonly used in engineering, mold making, and machine tool manufacturing to ensure precise hole locations and diameters.

 

Here is some important information about the DIN 179 standard:

 

1. Types of Drill Bushings: DIN 179 standard includes various types of drill bushings, with some common types being external convex drill bushings, internal concave drill bushings, cylindrical drill bushings, and angular drill bushings, among others. Each type is used for specific applications and installation requirements.

 

2. Materials: According to the DIN 179 standard, drill bushings are typically made of High-Speed Steel, a material known for its excellent hardness and wear resistance, suitable for guiding and positioning tools.

 

3. Dimensions and Tolerances: DIN 179 standard specifies the dimensions, tolerances, and specific design requirements for drill bushings. These requirements include outer diameter, inner diameter, length, design of the guiding section, and more.

 

4. Installation Methods: The DIN 179 standard also includes information on how drill bushings should be installed and secured to ensure they remain firmly in place in jigs or machine tools.

 

5. Standard Numbers: Depending on specific applications and requirements, DIN 179 standard has different parts and types, such as DIN 179A, DIN 179B, etc. You can choose the applicable standard section based on your specific application needs.
