I worked alongside a wonderful woman called Hinez. Company bought dies already produced to a smaller sized hole in them . Once used for many a thousand miles of wire drawing the friction between the diamond and wire touch it caused a ring to appear. This then caused ongoi g wear marks very quickly. I refurbished the dies by grinding the tip of a a pin approx 1 foot long I to various shapes . The pin then went onto a ultrasonic machine . The die went onto a spindle spinning below the pin. Add a mixture of olive oil and water to end of pin and turn on . After about 1 minute the vibration and diamond powder wore the die to shape of the pin The below video at 4.06 shows the ultrasonic machine in action. The same video at 5.49shows a very young me using a machine that then increases the bore to required size Now if I haven't bored you to sleep I have a die and one cut in half that shows the finished product somewhere
I spent my early days as a water pollution inspector visiting just about every factory in Sheffield, so got to see a lot of metal making processes. I just loved seeing the ingenuity of this sort of thing. Thanks for the video. Sorry about your old firm though.
Those were the early days of affordable camcorders, i took it to work to record the place as i had just got another job as the place was on its knees and on its way out of buisnes,however i left without a peny in my pocket,to find a couple of the lads were made redundant with a massive payout,almost enough to buy my house in them days, about 3 weeks after i left, such is life. and as Valveandy says ,no computers,no mobile phones just a group of folk who actually talk to each other . As an explination , i worked at one end of the room the "fine wire" end, the lads at the fare end were making tungston carbide dies for strip wire for use such as lightening conductors , those were the days.
