This machine tool is a specialized machine tool for machining cylindrical deep-hole parts, suitable for drilling and boring of cylindrical deep-hole workpieces. During drilling, an internal chip removal method (BTA method) is used, i.e., oil is supplied by an oil feeder, and the cutting chips are discharged from inside the drill rod to the chip hopper at the rear of the machine head through the cutting zone. During boring, oil is supplied from the tail end of the boring bar, and the chips are discharged to the chip hopper at the head of the machine head through the cutting zone.
Machine Tool Application: This machine tool is a special-purpose machine tool for machining cylindrical deep-hole parts, suitable for drilling and boring of cylindrical deep-hole workpieces. During drilling, an internal chip removal method (BTA method) is used, i.e., oil is supplied by an oil feeder, and the cutting chips are discharged from inside the drill rod to the chip hopper at the rear of the machine head through the cutting zone. During boring, oil is supplied from the tail end of the boring bar, and the chips are discharged to the chip hopper at the headstock through the cutting zone.
The machine tool bed guideway is rectangular and hardened for high wear resistance; the feed screw is installed in the middle of the bed guideway. The oil feeder uses a servo motor to clamp the workpiece, with adjustable pressure, ensuring safety and reliability. The oil feeder spindle has high concentricity with the machine tool spindle, resulting in good rotational accuracy; the guide sleeve is easy to replace. This machine tool is a deep hole drilling and boring machine that is easy to operate and control, and has high processing efficiency.

Coal Picks, also known as miner picks, conical picks, or rock picks, are essential cutting tools used in the mining and tunneling industries. They are specifically designed to fracture and excavate materials like coal, soft rock, and other minerals by being mounted on rotating drums of continuous miners, roadheaders, and shearers. Their primary function is to act as the point of attack, transferring the machine’s power into concentrated impact and shear force to break the material.

The cemented carbide gun drill bit for the geology and mining field is the core component of the gun drill tool. It is made of high-strength and high-wear-resistant cemented carbide material. Suitable for deep hole drilling operations in geological and mining exploration, it can perform efficient drilling in hard geological bodies such as rocks and ores. It features high drilling precision, smooth chip removal and long service life, and is compatible with various geological drilling rigs.
Four Axis CNC Deep Hole Gun Drilling Machine is used for processing automobiles, motorcycles, oil pump, nozzle, engineering machinery, mining machinery, military industry and other industries, small and medium-sized deep hole axial workpiece of special equipment.
Cemented carbide tapered ball tooth is a key cutting component of geological and mining equipment (such as DTH drills, roller cone drills). It adopts a tapered structure design, and the ball head has excellent impact toughness and wear resistance. It can effectively crush hard rocks and ores, and is suitable for drilling, blasting and other operations. It has the advantages of high crushing efficiency, strong impact resistance and being not easy to damage.
Carbide drill bits are high-performance cutting tools designed for drilling into hard, abrasive, or challenging materials. They are distinguished by their cutting edges or tips, which are made from tungsten carbide, a composite material known for its superior hardness and wear resistance compared to standard high-speed steel (HSS).
The CD Texture Cutter (Diamond Turning Tool) is a precision cutting tool made of high-quality diamond or cemented carbide substrate with diamond coating. It is mainly used to process uniform and high-gloss CD textures (concentric circular textures) on the surface of metal, composite materials and other workpieces. Widely applied in electronic equipment casings, decorative parts, precision mechanical components and other fields, it features high cutting precision, strong wear resistance and excellent processing surface quality.
Vertical lathes (VTLs) are specialized machining equipment designed for turning large, heavy, or oversized workpieces—ideal for industries like wind power (turbine hubs), shipbuilding (hull components), mining (equipment parts), and aerospace (large structural parts).

This machine tool is a special-purpose machine tool for machining cylindrical deep-hole parts. It is suitable for boring cylindrical deep-hole workpieces. During boring, an oil feeder is used to supply oil, and the chips are discharged to the chip hopper at the head of the machine through the cutting zone. During drilling, an internal chip removal method (BTA) is used, that is, an oil feeder supplies oil, and the chips are discharged from the inside of the drill rod to the chip hopper at the rear of the machine through the cutting zone.
The RFD6ZX1010-1000 six-axis drilling and milling compound deep hole drilling machine is mainly used for deep hole drilling and milling. Equipped with a high-precision CNC turntable (B-axis) and a sliding table rotation axis (A-axis), it can complete five-sided drilling and milling with one clamping. This expands the machine’s processing range, reduces clamping times, greatly improves processing accuracy and efficiency, and effectively saves production costs. It is mainly used for oblique hole processing in molds, mechanical parts, etc.
