Disclosed is a music bell vibrating plate
machining technology and a special tool. The music bell vibrating plate
machining technology comprises the following steps that traditional
polyester grinding wheel
cutting machining is replaced with special tool combined milling cutters, firstly,
cutting machining is conducted on a vibrating plate blank, then heat treatment is conducted on the vibrating plate blank, traditional machining procedures of a vibrating plate is changed radically, and the difficult problem that after plate
cutting, the heat treatment is conducted, and all voice keys are easy to deform in the heat treatment process is solved. According to the music bell vibrating plate machining technology, by adopting a technology method that the double-plate integrated vibrating plate blank is punched by a
punching machine and machined, cutting machining is conducted on the double-plate integrated vibrating plate blank by adopting the combined milling cutters, all the voice keys and chamfering areas are machined, it is ensured that the width of a cutting seam is 0.25
millimeter, the precision of the center distances of all the voice keys reaches 0.9+-0.005
millimeter, the rigidity of the vibrating plate is always kept 54+-1 degrees, each set of combined
milling cutter can
machine and produce 2-3 ten thousand vibrating plates, frequent replacement of tools is reduced, the work efficiency is improved, the precision of products and the stability of quality are ensured, voice of the vibrating plate is soft, pleasant to the ear and standard, and the quality and productivity of music bells are improved greatly.
