Harmonic drive uses a constructed controllable elastic deformation to transfer mechanical motion. Harmonic drive is usually composed of three basic components, including a rigid wheel with inner teeth, a flexible wheel with outer teeth that can produce radial elastic deformation when working, and a wave generator mounted inside the flexible wheel, precision Hamenako imported fine polishing equipment harmonic reducer CF-65-100-2UH wave, oval shape, with flexible rolling bearings in the outer ring. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel
There are many kinds of working fluids used in discharge machining, such as emulsion, deionized water and washing liquid. The most effective working fluid of ultrasonic edM polishing is emulsion. Emulsion is generally composed of base oil, Hamenaco imported fine polishing equipment reducer CF-65-100-2UH harmonic reducer emulsifier, cleaning agent, lubricant, rust inhibitor, brightener and so on.
C2 working voltage The processing voltage referred to here is the no-load voltage between the workpiece and the tool head. The processing voltage directly affects the polishing efficiency and surface roughness. Because when other conditions are constant, the size of the voltage directly affects and determines the size of the peak current. Harmonic speed reducer CSF-65-100-2UH and the peak current affects the roughness of the processed surface. The voltage usually used is below 30V.
The choice of the specific voltage depends on the surface roughness to be achieved. When the processing allowance is large, it needs to be graded polishing, such as coarse polishing, medium polishing and fine polishing. The applied voltage is higher in rough casting and smaller in fine casting.
C3> pressure of polishing tool on workpiece surface Polishing tool on workpiece The pressure of HARMONIC speed reducer CF-65-100-2UH of Hamenaco imported finishing equipment affects the roughness and quality of workpiece surface. It also affects the polishing speed.
In the rough throw, the pressure should be selected higher. The main purpose is to improve the polishing speed, so that most of the allowance with the fastest speed to remove. Because of the high pressure, the mechanical force of polishing is large, which can produce larger "burr". At the same time, the added processing voltage will be selected larger, hamenaco imported fine polishing equipment harmonic speed reducer CSF-65-100-2UH, so the removal speed is accelerated. Because in the higher voltage "burr" peak discharge energy is large, enough to make these "burr" will be melted away, but the pressure should be moderate, otherwise it will make the whetstone wear too fast.
