CNC Hole Drilling Machine Design Tips
October 26, 2018
When it comes to designing parts for manufacturing via CNC machining, there are a few rules to follow. Adhering to these rules will result in superior parts that are stronger, more accurate, and boast improved surface finishing. As we wrap up CNC machining week at HLH, we’re sharing a quick tip on how to design holes for your part or product.
For optimal design, all holes less than 20 mm in diameter should accommodate standard drill bit sizes, with a preference for metric sizes when possible. The depth of the hole is suggested to be 10 times its diameter or less. This consideration is crucial for both the drill holes themselves and the selection of the drilling head. When employing a deep hole drilling machine or engaging in CNC deep hole drilling, maintaining the right position and ensuring the workpiece is securely fixed becomes paramount.
The types of CNC drilling machines available, including those designed for specific hole CNC drilling operations, offer a variety of capabilities to address different drilling needs. The machine’s spindle plays a critical role in the drilling operation, affecting the precision and quality of the drilled holes. Additionally, the design should consider the groove placement, which can impact the part’s structural integrity and functionality.
By following this design tip and others that we will share, you can achieve a part design that is well-suited for CNC machining. Whether you’re utilizing a simple CNC drilling operation or complex milling and drilling processes, understanding the nuances of your CNC drilling machine’s capabilities, including its drilling head and spindle configuration, will greatly enhance the outcome of your manufactured part. Stay tuned for more CNC machining guidance from HLH to help you design successful parts for CNC machining.
