Spot drilling creates a small indentation on the workpiece’s surface, acting as a guide for subsequent drilling. This step ensures accurate hole placement and prevents drill bit wandering, making it crucial for precision machining.

Drilling is the process of creating cylindrical holes in a workpiece using a rotating drill bit. It is versatile, allowing for various hole sizes and depths, and can be applied to materials such as metals, plastics, and composites. This operation is fundamental in CNC drilling, offering both speed and precision.

Reaming is used to smooth and finish pre-drilled holes to a specific size and tolerance. It improves the hole’s accuracy and surface finish, ensuring that the hole meets precise dimensional requirements. This operation is essential in industries like aerospace and automotive, where tight tolerances and smooth internal surfaces are critical.

Boring involves enlarging an existing hole to a precise diameter. It provides more accuracy than drilling and is often used when a hole’s diameter needs to be customized. Boring is ideal for high-precision applications requiring exact hole sizes, such as in custom manufacturing processes.

Counterboring creates a stepped hole, where the top section is wider to allow a fastener (like a bolt or screw) to sit flush with or below the surface of the workpiece. This operation is widely used in assembly applications where surface aesthetics and functionality are important, such as in aerospace and automotive industries.

Similar to counterboring, countersinking forms a conical hole that allows screw heads to sit flush with the surface of the workpiece. This technique is common in mechanical assemblies, improving both the functional and aesthetic quality of the part by ensuring fasteners are properly recessed.

Tapping creates internal threads within a drilled hole, allowing for the secure insertion of screws or bolts. This process requires precise control over drill depth and rotation to ensure the threads are accurately formed. Tapping is essential for applications in assembly processes, such as in the automotive or construction industries, where secure fastening is needed.

Micro-drilling is used to create very small holes, often in the micrometer range. This technique is vital for precision applications, such as in electronics for circuit boards or in medical devices. Micro-drilling allows for the production of tiny, intricate components with extremely high accuracy.

Center drilling involves creating a conical hole at the surface of the workpiece to guide deeper drilling operations. It ensures proper alignment and prevents misalignment during further drilling. This is particularly important for deep or complex drilling tasks where accuracy is crucial, such as in aerospace and machinery manufacturing.

Peck drilling is used to improve chip removal and cooling during deep hole drilling. The drill bit periodically retracts to break up chips and clear them from the hole, reducing clogging and overheating. This technique enhances drilling efficiency and is essential for deep, clean holes in materials prone to chip buildup.

Gun drilling is a specialized technique for creating deep, straight holes with high precision. The drill bit used is long and thin, often with internal coolant channels to maintain accuracy over extended depths. Gun drilling is used for applications requiring deep holes, such as in hydraulic systems, aerospace, and medical devices.
