Advantages of Deep Hole Drilling Machines

Deep-hole drilling machines, distinct from conventional hole-machining methods, are specialized machine tools that rely on specific drilling techniques—such as gun drilling, BTA drilling, and jet-suction drilling—to perform drilling operations on deep-hole systems with a length-to-diameter ratio greater than 10, as well as on precision shallow holes. These machines epitomize advanced, high-efficiency hole-machining technology, delivering high precision, high productivity, and exceptional process consistency.

Advantages and Main Components of Boring and Burnishing Machines for Scraping and Burnishing

The machining speed of a scraping and burnishing machine tool is more than ten times that of a honing machine, while it operates with low noise and produces no pollution, thereby reducing processing costs and enhancing productivity. These advantages are inextricably linked to the inherent characteristics of the machine tool itself; therefore, today we will take a closer look at its main components.

What is a boring machine primarily used to machine?

Boring machines are primarily used to machine holes in workpieces with boring tools. They are mainly employed for high-precision hole machining or for the finish machining of multiple holes in a single setup; in addition, they can also be used to machine other surfaces related to hole finishing. Based on their structure and the workpieces being machined, they are classified into horizontal boring machines, coordinate boring machines, precision boring machines, deep-hole boring machines, floor-type boring machines, milling-boring machines, and drilling-boring machines. For detailed information, refer to textbooks on machining processes. These machines are primarily used for high-precision hole machining or for the finish machining of multiple holes in a single setup; moreover, they can also perform machining on other surfaces associated with hole finishing. All of these types are available for purchase at Kanmen Machine Tool Factory.

How should the machining challenges of CNC deep-hole drilling and boring machines be addressed?

CNC deep-hole drilling and boring machines are characterized by high precision, high efficiency, and a high degree of automation. When equipped with advanced drill bits such as gun drills, BTA drills, and jet–suction drills, they can complete in a single continuous operation processes that would normally require separate drilling, reaming, and broaching on conventional machine tools. However, during deep-hole drilling, these machines face challenges such as poor heat dissipation and difficult chip evacuation; moreover, the slender drill rods often exhibit poor rigidity, making them prone to bending and vibration. To address these issues, a hydraulic cooling system is typically employed.

Selection Requirements for Cutting Fluids for Deep-Hole Drilling Machines

Deep-hole drilling machines are specialized machining equipment designed for three-axis drilling, characterized by high efficiency, high precision, and a high degree of automation, and they employ external chip evacuation to drill small-diameter holes. With a single setup, these machines can achieve the same machining results that would normally require multiple operations—such as drilling, reaming, and broaching—on conventional machine tools. The machining accuracy of deep-hole drilling machines ranges from IT7 to IT10, with a surface roughness of Ra 3.1 to 0.04 μm and straightness tolerances of no more than 0.05 mm per 100 mm. Given these numerous processing advantages, what requirements does a deep-hole drilling machine impose on cutting fluids?
