From Gun Drilling to BTA: The Fundamentals of Deep Hole Drilling
Deep hole drilling is a machining process that revolutionized the manufacturing industry after World War I. Originally developed for making gun barrels, this technology has now expanded its applications across 15 different industries with over 200 unique uses. In this blog post, we will delve into the fundamentals of what deep hole drilling is, its major applications, and how Precihole Machine Tools is at the forefront of providing innovative solutions in this field.
Understanding Deep Hole Drilling
Standard drilling techniques have their limitations when it comes to length-to-diameter (L/D) ratios exceeding 10. To address the challenges of tool life, surface finish, hole straightness, roundness, and chip removal, deep hole drilling techniques are employed. The two primary methods are Gun Drilling and BTA Drilling.
What Is Gun Drilling?
Gun Drilling is a deep hole drilling process designed for creating long holes with diameters typically ranging from 1 mm (0.04’’) to 40 mm (1.5’’). This method involves pumping high-pressure coolant through a tube, while chips are evacuated from a V-shaped flute along the length of the tube from the outside.
What Is BTA Drilling?
BTA Drilling, also known as STS (Single Tube System), is a process used for creating long holes with diameters from 12 mm (0.5’’) to 250 mm (10’’). High-pressure coolant is pumped in from the outside of the tube, while chips are evacuated from the inside out.
Applications and Benefits of Deep Hole Drilling
This technology has become essential in various industries, especially when drilling exotic materials or hard super-alloys while maintaining accuracy and productivity. Achieving hole straightness, tolerance, and surface finish requires expertise and in-depth knowledge of the process. Factors such as machine features, process parameter selection, material input condition, tooling, coolant, and filtration significantly impact the output parameters.
Choosing the Right Configuration
Deep hole drilling can be performed using different configurations, depending on the application requirements and desired accuracies. Absolute Machine Tools offers a comprehensive range of deep hole drilling solutions tailored to meet your specific needs and optimize drilling performance.
