The terms' deep hole drilling and BTA are using to describe the process of generating boreholes with a high length-to-diameter ratio. Both processes have their advantages and disadvantages. In addition, they require special equipment and knowledge of the specific geological conditions in which they are used. Here, we will explain the differences between these two methods and their applications. In addition, we will explore the process of Gun-drilling, which is a type of deep hole drilling.
Gun drilling
Deep hole drilling, also known as BTA, is a drilling method where the diameter of the borehole is larger than its length. This technique can be used for several reasons, including the need for a very large length-to-diameter ratio. Below are some of the benefits of deep hole drilling. They include: - High accuracy - Increased productivity - Low risk - Reduced maintenance costs
Single-tube system (STS): The single-tube STS drilling system uses the opposite method to drill a hole. It consists of a drill head attached to a ground cylindrical tube via a threaded internal or external fast lead. The inner tube or boring bar is much smaller than the drill head. The annular space around the drill head is known as the "oil room" and can be used with a coolant induction unit or pressure head.
BTA drilling
Among the many types of drills, BTA and deep hole drilling are the most popular. They are both effective ways to drill holes with high length-to-diameter ratios. Below are some of the main differences between BTA and deep hole drilling. Whether you need a drilling company to drill large holes or small ones for a specific application, we've got you covered. Let's get started!
The BTA process uses a patented tapping system that eliminates the need for a pilot bore hole and taps steel from the interior. The system is designed and manufactured with precision and high-quality materials. BTA drilling is the best choice when your job requires high-quality surface finishes and low cost. But it's not the only method you should choose. There are several advantages of both methods. You'll benefit from a lower cost, a longer tool life, and a superior surface finish.
Gun drilling on a special machine
The basic material-removal process, gun-drilling, is highly demanding and a highly skilled skill. Despite its complexity, gun drilling has become a specialized area of manufacturing. As a result, many manufacturers have little or no knowledge of the relationship between point geometry and grinding process, resulting in wide variations in process performance. There are several key factors to consider when selecting a gun drilling machine:
First, a deep hole drilling machine is specially designed to provide the optimal conditions for gun drilling. It includes a high pressure pump that delivers lubricant to the rear of the machine, a spindle that drives the drill, and a high-pressure coolant to improve chip evacuation. The contra-rotating work piece and gun drill also contribute to the straightness of drilled holes. Deep hole drilling machines are equipped with advanced monitoring systems to identify dulling tools or other damage in the process.
