The elongated shaft refers to the shaft whose length to diameter ratio is greater than 25 (ie L/D>25).
Such as the lead screw, smooth rod, etc. on the lathe. Due to the poor rigidity of the slender shaft, it is easily deformed due to the effect and influence of the turning force, cutting heat and vibration during turning.
The spline shaft is a mechanical drive shaft. The spline shaft and the flat key, the half-round key, and the oblique key have the same functions, and they all transmit mechanical torque. There is a longitudinal keyway on the outer surface of the shaft, and the rotating part sleeved on the shaft also has a corresponding keyway, which can keep synchronous rotation with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears.
CNC machining of eccentric shaft or eccentric disc and eccentric sleeve
The axis of the outer circle and the outer circle are parallel, but the workpieces that do not overlap are called eccentric shafts. The eccentric shaft is generally fixed on the rotating shaft of the motor through an eccentric hole. When the motor is started, do a cam movement. Therefore, it is widely used in automobiles, engines, pumps, etc.
Cost and Quotation of Turned Parts
The cost of machining materials is certain. The main difference lies in each company’s different labor costs, transportation costs, consumption costs, and taxes. So these parts CNC machining plant in what way it is calculated mostly by?
The following is a compilation of part of the CNC turning data for reference (because the calculation method varies depending on the price of each place).
Card cigarette electronic cigarette accessories, C54, CBD atomizer, electronic aluminum cigarette casing, etc. Precision CNC machining: aluminum alloy, PEEK, PPSU,PC, ABS, PP, PE, PEI, POM
The fuselage of electronic cigarettes generally includes metal plastic composite molding, TPU or TPE soft rubber two-color injection molding, and silicone rubber molding. Special protection will be done on the battery compartment cover and interface and other electrical parts to achieve the “three-proof” effect of waterproof, dustproof, and drop-proof.
The threaded waterproof breathable valve produced by CNC is a durable, threaded breathable valve. It is easily assembled into existing equipment and can be used in various applications such as control circuits.
CNC precision machining mainly includes fine turning, fine boring, fine milling, fine grinding and grinding processes:
(1) Fine turning and fine boring: Most of the precision light alloy (aluminum or magnesium alloy, etc.) parts in the aircraft are mostly processed by this method.
