Analysis of machining difficulty and applicability of vertical deep hole drilling

Vertical deep hole drilling is a machine tool equipment for machining deep holes. Its machining difficulty and applicability are related to its characteristics and process.

Machining difficulty:

1. High requirements for machining accuracy: Vertical deep hole drilling requires high precision machining capability, especially the diameter, roundness and surface finish of deep hole machining.

2. High requirements for machining tools: As the deep hole drilling needs to be further extended to the inner part of the workpiece for machining, the rigidity and stability of the machining tools are required to be high, once the tool vibration or deflection, it will lead to a decline in the quality of machining.

3. The machining difficulty is related to the workpiece material: different materials of the workpiece need to choose different cutting parameters and empirical data, so the machining difficulty is closely related to the selected workpiece material.

Applicability:

1. Suitable for deep hole machining: vertical deep hole drilling is specially used for machining workpieces with large diameter of deep holes, usually for workpieces with length to diameter ratio more than 10, such as special parts, large pipes, automobile engine blocks, etc.

2. Suitable for mass production: Vertical deep hole drilling is usually used for mass production, which can improve production efficiency. For workpieces that need to be processed in large quantities with similar structures, vertical deep hole drilling can improve production efficiency and reduce production costs.

3. Suitable for high accuracy machining: Vertical deep hole drilling has high machining accuracy, which can satisfy some workpieces with high accuracy requirements, such as aerospace parts, precision instrument parts and so on.

In summary, vertical deep hole drilling is more difficult to process, higher requirements for machining accuracy and tooling, but also has good applicability, especially for deep hole machining and mass production, and can meet the needs of high-accuracy machining.
