Deep Hole Drilling in the Complete Machining Centre

Jul. 05, 2023

Deep hole drilling is a specialized machining process used to create holes with a high length-to-diameter ratio. It involves drilling holes that are significantly deeper than their diameter, typically defined as having a depth-to-diameter ratio of 10:1 or more. Deep hole drilling is often required in industries like aerospace, automotive, oil and gas, and medical, where precision, accuracy, and reliability are critical.


Complete Machining Centre:

A complete machining center, also known as a multi-tasking or multi-function machining center, is a type of machine that integrates multiple machining processes into a single setup. It combines capabilities like milling, turning, drilling, boring, and more in one machine, allowing for the efficient production of complex parts without the need for multiple setups or tool changes.

Deep Hole Drilling in Complete Machining Centre:

The integration of deep hole drilling capabilities into a complete machining center offers several advantages:


1. Time and Cost Savings:

By performing deep hole drilling and other machining operations in one setup, a complete machining center reduces the overall production time and cost. There is no need to transfer the workpiece to different machines, minimizing handling and setup time.


2. Improved Accuracy and Precision: 

Complete machining centers are equipped with advanced CNC controls and tooling, ensuring high accuracy and precision in deep hole drilling and other operations. This level of precision is especially crucial in industries with strict tolerance requirements.


3. Complex Part Production: 

The ability to perform multiple machining processes in a single setup allows for the production of complex parts with intricate features. This makes complete machining centers ideal for manufacturing components that require both deep hole drilling and other machining operations.


4. Flexibility and Versatility: 

Complete machining centers are versatile machines that can handle a wide range of materials and part sizes. They can be programmed to perform various machining operations, including deep hole drilling, to accommodate different production needs.


5. Reduced Workpiece Handling: 

Minimizing workpiece handling during machining reduces the risk of errors and damage to the part. It also streamlines the production process, leading to higher efficiency and productivity.


6. Consistent Quality: 

Complete machining centers provide consistent and repeatable results, ensuring that each part meets the required specifications. This level of consistency is crucial for industries where safety and reliability are paramount.


Challenges and Considerations:

Despite the advantages, deep hole drilling in a complete machining center also presents some challenges:


1. Rigidity:

Deep hole drilling machine requires stability and rigidity to ensure accurate results. The machine's structure must be robust enough to handle the cutting forces involved in deep hole drilling.


2. Tooling and Coolant Supply: 

Specialized deep hole drilling tools and effective coolant supply systems are essential for efficient chip evacuation and temperature control during the drilling process.


3. Chip Management: 

Proper chip management is crucial in deep hole drilling to prevent chip clogging, which can lead to poor hole quality or tool breakage. The machining center must be equipped with efficient chip removal systems.


4. Operator Training: 

Deep hole drilling is a specialized process that requires skilled operators who understand the intricacies of the drilling parameters, tooling, and coolant management.



Integrating deep hole drilling capabilities into a complete machining center offers significant advantages in terms of time and cost savings, accuracy, and flexibility. However, it requires careful consideration of machine rigidity, tooling, coolant supply, and operator expertise to ensure successful deep hole drilling operations.
