Top Tips for Buying Diamond Wire Drawing Dies

The machinery industry is constantly changing. Let’s have a look at the evolution of diamond wire drawing tools and their equipment. The first generation of diamond wire drawing dies is mechanical grinding. This is used to make and maintain diamond drawing tools. It is very inefficient, so it is rarely used.

The second generation is that the tube magnetostrictive type,which converts the electrical signal provided by the tube amplifier into energy through the magnetostrictive transducer to grind the diamond dies mold.

The disadvantage of this sort of transducer is that the conversion efficiency of magnetostrictive transducer is just too low,and external circulating cooling water is required to chill it.The breakdown rate is high,and there are few manufacturers using it at the present .

The third generation is that the transistor piezoelectric type,which converts the electrical signal provided by the transistor power supply into mechanical vibration through the piezoelectric ceramic transducer.Its advantage is that the piezoelectric ceramic has high conversion efficiency and doesn’t need an external cooling system.

So far,this type of machine has been widely used,gradually replacing the old mechanical grinder and tube magnetostrictive grinder,becoming the mainstream of wire drawing dies manufacturing equipment.

Its disadvantages include:large harmonic distortion of transistor circuit,transverse vibration of transducer,and low yield of diamond.When the output power is high,the transistor is straightforward to be damaged, so it can’t be wont to manufacture the super large aperture polycrystalline diamond wire drawing dies.

The fourth generation is precision integrated ultrasonic EDM technology and equipment,which is developed by Beijing Electric Machining Research Institute.This kind of machine adopts high-power top-level sound microcircuit ,with micro precision EDM power supply,through the conversion of piezoelectric ceramic titanium alloy transducer,the diamond wire drawing dies is processed by ultrasonic and EDM.

It is a hi-fi sound amplifier chip which provides ultrasonic signal.Its internal circuit is powerful,including automatic gain negative feedback circuit (AGC),temperature overheating protection circuit and cargo short protection circuit.It has the benefits of small total harmonic distortion and low noise.Titanium alloy transducer has low impedance,high Q value,low internal loss,high mechanical strength,long service life,stable performance and better conversion efficiency.

The combination of top-quality audio circuit and piezoelectric ceramic titanium alloy transducer produces very pure ultrasonic wave without clutter and transverse vibration.The diamond wire drawing dies processed with this tool has good hole shape and high surface finish. When machining large aperture polycrystalline diamond dies mold,if combined with EDM,the machining efficiency are going to be doubled. Read more:
