BTA Deep Hole Drilling Machine ROTODEEP-HOLE

Deep hole drilling machine is specifically designed for creating precise, deep holes for cylinder-shaped workpiece. These machines typically features specialized drill bits, such as gun drills, BTA tools, or ejection drills, which are designed to handle deep drilling and allowing for efficient chip removal and high-quality surface finishes. Depending on the machine configuration and tooling the drilling diameters generally ranges from 30 mm to 120 mm.

The drilling diameter of medium diameter BTA deep hole drilling machine can range between 30 mm to 120 mm.

Product Description

Deep hole drilling machines are highly specialized pieces of equipment engineered to create accurate and precise deep holes in cylindrical or complex-shaped workpieces. These machines are essential in various industries where deep and accurate holes are required, such as in the production of components for the automotive, aerospace, oil and gas, and mold-making sectors. The defining characteristic of a deep hole drilling machine is its ability to drill holes with a high depth-to-diameter ratio, which is difficult to achieve using standard drilling equipment.

Deep hole drilling machines utilize advanced drill bit technology, such as gun drills, BTA (Boring and Trepanning Association) tools, or ejection drills. Each of these tools is designed to meet the specific challenges of deep drilling, such as ensuring straightness, providing effective chip removal, and achieving superior surface finish quality.

Gun Drills: These are single-lip tools known for their precision and are ideal for smaller diameters. BTA Tools: BTA (Boring and Trepanning Association) drills are used for larger diameters and feature an internal coolant supply system to flush chips away from the cutting zone. Ejector Drills: These tools allow for fast and efficient drilling by using a dual-tube system to remove chips while maintaining coolant flow for optimal performance. In addition to the variety of tooling, deep hole drilling machines are designed to handle a range of drilling diameters, depending on the configuration. The medium-diameter BTA deep hole drilling machines, for instance, are commonly used for drilling diameters ranging from 30 mm to 120 mm. These machines excel in creating deep, straight holes while maintaining tight tolerances and high levels of surface finish, even in difficult materials like steel, cast iron, and alloys.

Moreover, these machines are often equipped with sophisticated control systems that monitor drilling parameters such as spindle speed, feed rate, and coolant flow to ensure efficient and precise operation. The machines' robust construction allows them to handle high cutting forces and heat, making them suitable for continuous operations in industrial environments.

The applications of deep hole drilling machines extend to a wide range of industries. For example, they are crucial in the manufacturing of components like hydraulic cylinders, oilfield equipment, aerospace landing gear, and molds for injection molding. These machines provide the ability to create deep bores in workpieces with minimal deviation, ensuring both reliability and efficiency in high-demand manufacturing processes.

In conclusion, deep hole drilling machines are indispensable tools for industries that require the precise and efficient drilling of deep holes. By employing advanced tooling technology and machine configurations, these machines can accommodate a wide range of drilling diameters, ensuring the quality and accuracy needed for critical industrial components.
