Types of Deep Hole Drilling Machines

Deep hole drilling machines are available in various types, each tailored to fulfill particular drilling demands and material specifications. The primary varieties include:

Gun Drilling Machines

Gun drilling machines are engineered to create straight, precise holes with a high length-to-diameter ratio. They utilize specialized gun drills featuring a single, straight flute for effective chip evacuation.

• Single-Spindle Gun Drilling Machines: These machines are optimal for drilling small to medium-sized holes, delivering high precision and are frequently used in the automotive and aerospace sectors.

• Multi-Spindle Gun Drilling Machines: Equipped with several spindles, these machines allow for simultaneous drilling of multiple holes, greatly enhancing productivity and efficiency.

Exapro showcases a variety of gun drilling machines, ensuring businesses can find the ideal equipment for their precision drilling applications.

BTA (Boring and Trepanning Association) Drilling Machines

BTA drilling machines, or ejector drilling machines, are utilized for larger diameter holes and extended depths compared to gun drills. These machines incorporate a tube to deliver coolant to the cutting head and facilitate chip removal through the center of the drill.

• Single-Spindle BTA Drilling Machines: Suitable for heavy-duty operations, these machines excel at producing large-diameter deep holes.

• Multi-Spindle BTA Drilling Machines: Designed for high-volume production, these machines enhance efficiency by enabling the simultaneous drilling of multiple holes.

Exapro's inventory includes various BTA drilling machines suitable for different industrial uses and production capacities.

Trepanning Machines

Trepanning machines are employed for creating large-diameter holes by extracting a core from the material rather than fully drilling it out. This approach is resource-efficient and minimizes material wastage.

• Manual Trepanning Machines: These machines are optimal for small operations or custom drilling tasks, where accuracy and control are crucial.

• CNC Trepanning Machines: Featuring computer numerical control (CNC) technology, these machines provide high precision, consistency, and automation, making them ideal for large industrial applications.

Exapro provides a range of trepanning machines, enabling companies to select the correct model per their specific requirements and production goals.
