Tungsten Carbide cutter.


Recommended Posts

Just taken delivery of a new cutter. First time i've used a Tungsten one. Fitted it and was ready to try it out. As soon as I put a stilletto heel to it, it near friggin ripped my fingers off. It snatched the boot and flung it!!

 

Is this supposed to happen? I appreciate it's a new cutter but this has never happened with other new cutters. Even when applying the lightest of pressure - it still snatches.

 

Is it a Tungsten thing??

Gently, gently when first using Tungsten :wink: Try using some leather offcuts on the cutter first just to ease it in. I would use an alternative method for finishing your pu's for a while, it's just that the material is hard and the cutter will 'dig' for a short period till the edge starts to ease off :) 15-20 pairs of rubber/nitrile should make it a little less snatchy, or even a few mens heels :wink:

Thanks Keith,

 

I only use that cutter for trimming pu's etc so will have to swap it and end of the day and run some leather and rubber offcuts off.

 

Gently gently is a bloomin understatement!!! It gave me fright when it snatched the shoe from me.

 

Ta,

Iain

Bare in mind the following. All cutters, when sharpened, suffer with a larger space between the teeth as you are removing metal :D , which will get larger everytime they are sharpened. :shock:

 

If you choose to have your cutters sharpened on an exchange basis, the one you recieve may well be sharper, but more of a handfull to use, ie, grabbier :shock:

 

Net result, possibly worse off :?

I miss my old K&B machine!! It had the abrasive trimming wheel which was great. We will be looking at new machinery prob at the end of next year. I for one will insist on a multi-head as shown on that 710.

 

We've never had our cutters sharpened,just keep buying new ones and saving them up!!!

 

We'll see how this Tungsten bad boy works out.

mine is about 6 months old and it is still very sharp but as the lads said you will get used to it and it is much quiker than a regular cutter.i still sometimes scour pu,s if they are a bit wide.just make sure your guide is set right cos it will trim the actual heel if its not set properly

Another benefit of Tungsten cutters is the waste. Most repairers overuse a heel cutter till it's well beyond it's sell by date. If you look at the waste produced, you will notice thats it's very dustlike.

 

With a new cutter, you will notice that the waste is much larger. The benefit to the user is that there is much less airbourne dust around, healthier and cleaner. You normally find that it sticks to the machine as it becomes electrostatic as it trims, but it's mech easier to brush of your machine without it reaching the atmosphere :wink:

 

We fit Tungsten heel cutters on all machines leaving our factory, new or reconditioned. :D

while we are on the subject of cutters, this is about sole cutters and their shields

i have a new finisher which has new sole cutters and a great tungston heel cutter, but the sole cutters seem to have and a raised bit by the shield so that when i trim welted shoes it cuts like a groove in the welt also the shields seem a tad not wide enough.

have they started to make the cutter a bit wider or can you have ones thay don't have that raised bit any constructive ideas would be greatly received and remember this is the time of year we should all be good christians so if you take the piss i'll just laugh and show you the other cheek.

if i could i would have tungston sole trimmers to i love a bit of snatch ing

hi keith & peter

 

yes everything fine keith but trade is not as brisk as i would like but not to worry.

 

ah thanks peter , maybe my old tungston sole trimmers had been sharpened so much that raised part had nearly worn out and did not do it as much.

 

iain did you get the right tungsten cutter for your machine as some will not work properly because the finisher motor runs slower on some machines. i could not use any of my tung. sole cutters on my new machine because of this.

happy christmas

You are using a tungsten cutter on your heel trimmer which works fine. It runs at the same speed as your forepart cutter, why would they not trim if they run at the same speed? :?

 

Admitedly, the 710 runs at around 6000 compared to a Power Unit or Lynx which runs at around 8000, but I'm not sure this would make that much difference.

 

As a point of interest, Tungsten forepart trimmers are predominently used in factories where their machines run at around 14000 or more. My personal preference is to run HSS forepart cutters on finishers due to the high probability of shoe damage with tungsten. They can take big lumps out of welts :shock:

Farty,

 

Yes, I believe I bought the right cutter. It's the same size all the others I've purchased but in Tungsten. It fits the machine perfectly. I think Rick will be trimming away with it today on all manner of materials to ease it in.

 

If I get a call that he's having his fingers put back on then i'll go back to the old one :lol:

hi chaps

 

keith i think its down to the number of teeth on sole trimmers and mine had a lower amount so would bite and take chunks out of the sole when i tried to use them on this finisher. by the way i'm not saying theres anything wrong with the 710. i am very happy with it and the hss cutters that you supplied.

iain if you brought your tung cutter from keith or peter it will be the right one and but some only had 12 or 13 teeth i think and these are the ones to avoid.

good luck they soon calm down, hopfully by the time you get back on the finisher..

 

cheers

I run an old WHB 700 (1984 model, yes the red one)

Spindle speed is 6100 RPM & have 16 tooth tungsten carbide hobbing cutter.

From memory it's not been re-ground in over 4 years & still performs well on trimming PU's, Rubber, JR leather, Micro & metal tops.

When new the the waste produced is like fine flakes, but mine now is like a swarf on PU & PVC & a little dusty on other materials, will invest in a new one soon, as the 3 I have, have all been re-ground couple of times.

Speak for yourself sonny!!

 

That Tungsten-tipped ring of evil hates me! I can hear it whispering 'give us ya fingers ya big-chinned sack o lard!!'

I swear it can smell my fear!!

 

Looks like i'm off the machine till it eases up on me. Damn it's powerful though. Can those things be sharpened?
