So far, uses for to make the electric wire electric cable's diamond wiredrawing mold and the equipment, had already experienced four generation of transformations.
  First replaces the mechanical lapping type, uses the mechanical lapping the way manufacture and the service diamond wiredrawing mold, this way's efficiency is extremely low, the produce by rubbing mold hole type difference, very little has used at present.
  Second replaces the electron tube magnetostriction type, provides the electrical signal the electronic amplifier, transforms the mechanical energy through the magnetostriction type transducer, uses for to grind the diamond mold. This kind of type's shortcoming is the magnetostriction type transducer's transfer efficiency is too low, and needs the external connection recirculated cooling water to its cooling. The equipment failure rate is high, at present uses the factory are not many.
  The third generation for the transistor piezoelectricity type, the electrical signal which provides the transistor power supply transforms through the piezoelectric ceramics transducer the mechanical vibrations, its merit is the piezoelectric ceramics transfer efficiency is high, and does not need in addition the cooling system. The equipment volume reduces, so far this type application are most, substitutes for the old style mechanical grinder and the electron tube magnetostriction type grinder gradually, becomes the die making equipment's mainstream. Its shortcoming includes : The transistor circuit harmonic distortion is big, the transducer easy to produce inspires horizontally, when makes the rough diamond small aperture mold with this kind of type, the diamond easy stave and the break, the rate of finished products is low. When high efficiency output, the transistor easy to damage, is unable to use for to make the ultra big aperture crystal combination diamond wiredrawing mold.
  Fourth replaces the precise integrated piezoelectricity type ultrasonic wave electric spark compound process technology and the equipment, by Beijing Electrical finishing Research institute development and development. This kind of type uses the high efficiency top sound integrated circuit, matches by the micro fine electric spark power source through the piezoelectric ceramics type titanium alloy transducer's transformation, carries on the ultrasonic wave, the electric spark compound processing to the diamond wiredrawing mold. Its characteristic is the achievement provides the supersonic signal the high fidelity sound amplifier chip, the internal circuit function is formidable, contains the automatic gain control electric circuit (agc), the temperature overheated protection circuit, the load short circuit protection circuit, has the total overtone low distortion, the low noise merit. The titanium alloy transducer impedance is low, the q value is high, the interior loses, the mechanical strength to be high slightly, the life is long, the stable property, the transfer efficiency is higher. The best quality goods sound electric circuit and the piezoelectric ceramics type titanium alloy transducer's union, has the very pure ultrasonic wave, does not have the clutter with to inspire horizontally certainly. The diamond wiredrawing mold pass which processes with it is good, the surface smooth finish is high. When processes the big aperture crystal combination diamond mold, if matches by the compound electric spark, processing efficiency multiplication.
  Fourth generation of precise integrated piezoelectricity type ultrasonic wave manufacturing machine's development. Was Beijing Electrical finishing Research institute develops first at the end of 1991 successfully, and applied very quickly in the diamond wiredrawing die making domain. The first batch of machine's model is bdc-50a, the development goal is to enhance makes the rough diamond small aperture mold's precision, causes the base roundness and the pass precision reaches the submicron level, the surface roughness achieves the mirror surface level.
