Bearing refers to the mechanical parts used to support the rotating shaft or other rotating parts, guide the rotating movement, and bear the load transmitted to the support. It generally refers to rolling bearing.
Rolling bearing mainly includes bearing inner ring and shaft
There are four major parts: bearing outer ring (commonly known as bearing ring), rolling element and cage. The accuracy of rolling bearing from low to high is P0, P6, P5, P4 and P2, of which P0 is ordinary level and can not be marked; P6 has certain accuracy requirements and has a wide range of applications; P5 grade requires high precision, sometimes called precision grade, which is mainly used for machine tool spindle; P4 and P2 levels are sometimes called ultra precision level, with extremely high precision requirements. They are mainly used for high-speed precision machine tool spindles and other occasions
The main transmission shaft on the machine tool that directly drives the rotation of the workpiece or cutting tool (drill bit, grinding wheel, etc.), and its spindle refers to the rotation accuracy, which directly affects the machining accuracy of the workpiece. It is driven by a motor and the speed is adjusted through a mechanical gearbox
It is a mechatronics product that replaces the traditional cutting spindle and mechanical speed change system. It is the core component of the motorized spindle of machine tool. It is directly regulated by the control system without mechanical speed change system, which can simplify the structure of the machine tool and improve the machining efficiency and precision. Its quality and level represent the manufacturing level of mechanical basic parts. Compared with ordinary spindle, it has the advantages of high speed, high precision and high stability
Superhard materials refer to materials whose hardness can be compared with diamond, mainly cubic boron nitride and diamond; Boron carbide, twin diamond, silicon carbide and other intergroup III and IV compounds are still under development.
It is made of diamond powder and cemented carbide substrate sintered under ultra-high pressure and high temperature. It not only has the high hardness, high wear resistance and thermal conductivity of diamond, but also has the strength and impact toughness of cemented carbide. It is an ideal material for manufacturing cutting tools, drilling bits and other wear-resistant tools.
Wire drawing die refers to all kinds of dies for drawing metal wires.
Polycrystalline diamond (PCD) is made of graphite by unique directional blasting method. The shock wave of directional blasting of high detonation velocity explosive accelerates the flight of metal flyer and impacts the graphite sheet, resulting in the conversion of graphite into polycrystalline diamond.
Polycrystalline diamond composite (PDC) is a kind of composite material formed by polycrystalline diamond and cemented carbide. It has not only the high hardness of PCD, but also certain toughness and impact resistance. It is an important superhard tool material.
