Dezhou Drillstar Co., Ltd. will showcase a range of advanced machine tools and cutting tools, including:

– Broaching Machine: A high-efficiency machine tool that uses broaches to machine through holes, planes, and shaped surfaces of workpieces. It can achieve high-precision machining, is suitable for mass production, and can meet the precision machining needs of various industries for parts.

– Deep Hole Drilling Machine: Utilizing specific drilling techniques, such as gun drilling and BTA drilling, this machine performs drilling on deep holes with a length-to-diameter ratio greater than 10 and on precision shallow holes. Representing advanced and efficient hole machining technology, it boasts high precision, high efficiency, and high consistency, achieving precision machining results in a single pass. It can machine various complex deep holes.

– Gantry Machining Machine: Possessing powerful machining capabilities, this machine is suitable for various machining processes such as milling, boring, and drilling of large parts. It ensures the machining accuracy and surface quality of large workpieces and plays a vital role in aerospace, shipbuilding, and other fields.

– Boring Machine: Primarily used for precision machining of holes in workpieces, it ensures the dimensional, shape, and positional accuracy of the holes. It is an indispensable machining equipment in industries such as machinery manufacturing and automotive manufacturing.

In addition, we will showcase various types of deep hole drilling tools, such as BTA, indexable gun drills, welded gun drills, and solid carbide gun drills. These tools utilize advanced materials and manufacturing processes, possessing excellent cutting performance and durability, and can meet the deep hole machining needs of different materials and processing requirements.

– BTA Deep Hole Drill: This is an internal chip removal deep hole drill. Its working principle involves cutting fluid being introduced through the gap between the drill rod and the hole wall, and the cutting fluid pressure forcing chips out of the drill rod’s inner bore. The insert has double-sided staggered teeth and is equipped with guide blocks, providing good guidance during drilling and preventing deflection. The drilled deep holes have good straightness, achieving machining accuracy of IT7-IT10 and a surface roughness of Ra3.2-1.6μm. It is commonly used in deep hole machining in aerospace, automotive, and other fields.

– Indexable Gun Drill: This is a tool specifically designed for deep hole machining; it typically consists of a tool holder and replaceable carbide inserts. The inserts are fixed to the tool holder by screws or other means, requiring no grinding and facilitating easy replacement of inserts and guides. – High Precision: Utilizing advanced manufacturing processes, it ensures the straightness and parallelism of drilled holes, maintaining excellent straightness and cylindricity even in deep hole machining with large aspect ratios.

– High Wear Resistance: Made with high-quality cemented carbide materials and a special coating treatment, it maintains excellent cutting performance even when working with high-strength and high-hardness materials.

– Efficient Chip Removal: By optimizing the blade geometry and designing chip flutes, it generates narrow chips that are easily removed. Combined with a good cooling system, it effectively removes heat and debris, improving machining stability.

– Welded Gun Drill: The drill bit consists of a drill tip, drill rod, and drill shank welded together as a single unit. The drill bit is typically made of solid cemented carbide, with the tip brazed to the heat-treated drill rod, and then brazed to a precision-ground steel drill shank. It offers high hole machining accuracy, good economy, and high cutting stability. It can be re-sharpened multiple times, and the tool length can be customized according to customer requirements. It is suitable for gun drilling machines, machining centers, and other equipment. Welded double-edged gun drills are suitable for machining materials with easily breakable chips, offering high drilling speeds and are commonly used in the machining of cast iron products.

– Solid carbide gun drills: Made of high-quality cemented carbide, these drills possess extremely high hardness and excellent heat and wear resistance, making them particularly suitable for deep hole drilling of difficult-to-machine materials such as stainless steel and titanium alloys. Through optimized cutting edge design and geometry, they reduce cutting forces and vibrations, improving machining efficiency and surface finish. Special coating technology further enhances wear resistance and extends service life. Furthermore, solid carbide gun drills are manufactured with strict tolerance control, ensuring consistent and precise results in every machining operation. They are suitable for machining various materials and are widely used in aerospace, automotive manufacturing, and other fields.
