After three years of research and development, Karma Tools successfully launched a series of carbide thread drilling and milling integrated knives in 2013, and officially supplied bulk supplies for FAW-Volkswagen and other auto parts manufacturers, in aluminum alloy clutches, differentials and Good processing is applied to the machining of parts such as the knuckle housing. Carbide thread drilling and milling integrated knife is one of the most advanced CNC tools for internal thread machining. The remarkable features of thread drilling and milling cutters are functional compounding, high efficiency and precision. It can be used in one tool, integrating threaded bottom hole drilling, hole chamfering and thread milling. This is a “functional compositeâ€; M12×1.5 thread drilling and milling in the test of FAW-Volkswagen clutch and differential housing The speed of the knife reaches 10000r/min, the cutting speed Vc=329m/min, F=2400mm/min, the efficiency is amazing, this is “high efficiencyâ€; the processed thread has high smoothness, stable size, and the coaxiality of the bottom hole and the thread is good. The medium diameter can be compensated, this is "precision". In order to achieve high-speed cutting, the thread drilling and milling integrated knife must be an internal cooling structure. As can be seen from Figure 3, the internal cooling design of the thread drilling and milling integrated knife is very distinctive, that is, the top of the drilling blade is a multi-cooling hole, and the threaded edge portion is a single cooling hole, which is to ensure that the tool is at the bottom of the drilling. Both holes and threads can be used for good cooling. The design of the inner cooling holes makes the material manufacturing more difficult, and it must be ensured that the precision of each material is very high, slightly deviated, and the inner cooling holes are worn through during processing. High-speed cutting is also a big test for the wear resistance of the material. Despite the aluminum alloy processing, the common alloy material is used, and the drilling blade is prone to burns, resulting in a greatly reduced life. The thread drilling and milling cutter is mainly for axial feeding in the bottom hole and the hole chamfer. The material is required to be hard enough, but in the thread milling, the radial feeding is mainly required to bear a large lateral force. The toughness of the material has been extremely high, so the selection of ultra-fine grain materials with very high hardness and toughness has become the only way. Excellent groove, blade, tooth and geometry design, advanced CNC equipment and scientific manufacturing process, plus polishing treatment and reasonable coating selection, the thread drilling and milling integrated knife can cut lightly, and It can discharge chips smoothly, and it can dissipate heat quickly, achieving high efficiency, high precision and long life. It can compete with international first-class brands. Single Acting Hydraulic Cylinder A single acting hydraulic cylinder is a type of hydraulic cylinder that uses hydraulic pressure to move in one direction only. It is designed to extend or retract under pressure from one side only, using a piston and rod assembly. The cylinder is usually mounted in a fixed position and the force is applied to the piston rod to move the load. Single acting hydraulic cylinders are commonly used in applications where the load needs to be raised or lowered, such as in dump trucks, construction equipment, and agricultural machinery. They are also used in industrial applications where precise control is required, such as in metalworking and material handling equipment.
