The invention discloses a multi-point ultrasonic vibration CBN grinding wheel dressing device, which is mainly composed of a bed, a three-phase asynchronous motor, a grinding wheel, a support plate and a four-point positioning chuck. The three-phase asynchronous motor is arranged above the left end of the bed, and the grinding wheel is arranged At the right end of the three-phase asynchronous motor, an up and down adjustment device is set between the three-phase asynchronous motor and the bed, the support plate is slidably connected to the bed, and the four-point positioning chuck is fixed on the top of the support plate. The present invention is simple in structure and easy to operate. Turning the voltaic wrench enables the four sliders to move along the normal direction at the same time, so that the cutting forces at symmetrical positions cancel each other out, improving the rigidity of the cutting system and the stability of cutting. The slider structure adopts ultrasonic vibration technology, which makes the surface of the dressed CBN grinding wheel sharp and has a large chip space. Compared with the laser trimming method, the invention greatly reduces the deformation amount and cutting force on the surface of the CBN grinding wheel, significantly reduces the cutting temperature, and prolongs the service life of the CBN grinding wheel.
Description
technical field [0001] The invention relates to a multi-point turning and dressing device, and relates to ultrasonic vibration dressing technology, which is suitable for high-efficiency and precise dressing of CBN grinding wheels. Background technique [0002] At present, the commonly used processing methods of CBN grinding wheels include ordinary turning method, laser dressing method and electric discharge dressing method and so on. Ordinary turning method dressing grinding wheel device generally adopts single-point polycrystalline diamond pen turning to achieve the purpose of dressing. However, the efficiency is too low, the cutting tool and the grinding wheel wear quickly, the cutting is uneven, and the surface quality of the grinding wheel cannot be guaranteed. In order to achieve high-efficiency trimming, people often use laser trimming and discharge trimming. The laser dressing method realizes the effective removal of the grinding wheel material and achieves the purp...
