    hi guys

    I have replaced my cutter blade 4-5 times this year but seldom did it in previous years, and I am wondering if I am now doing something wrong, different or whatever, that makes this happen?

    They are not an expensive thing to replace but this year it is noticeable how many I am going through and I cannot work out why?

    How long do you normally get from your blade before you have to swap it?
    Any advice on what I could be doing wrong?

    thanks in advance. 🙂

    What blades are you using. smart knives or standard blades in holders? 4-5 times sounds a lot but depends how much work your churning out. When i was using standard blades i would change 3-5 times a year. Now im using smart knives it looks like its 1-2 years.

    Maybe your cutting strip needs replacing? or like you say your cutting slightly too deep

    If you’re just vinyl cutting, they should last a reasonable length of time. We do a lot of die cutting on our plotters, which cuts through the backing paper as well. Doing this eats blades, and we can easily go through 1-2 per month

    All depends what you’re doing with them.

    I don’t keep a tally on how often I change them, I just change as and when required.

    If I’m cutting laminated reflective film, it soon dulls it, then when I come to cut some small text it’s a pain to weed. Upping the pressure works to a point. I don’t cut huge amounts, but do a wide variety of media.

    We use separate blades for reflective vinyl, i never use the reflective smart knife to cut anything else. Also have a separate one for sandblast film as well.

    For vinyl cutting we start very light to begin with, just enough to get through the material, any deeper and you’re cutting backing paper & that will destroy any blade very quickly. You can hear when it’s cutting too deep so start at zero & build up gradually until you have the ideal depth. You’ll increase the depth as the blade wears & no longer cutting efficiently. It all depends what material you’re cutting to gauge lifespan. Worth having a chat with Harry at Edward Mathias, not much he doesn’t know about plotters. Make sandwiches & a flask first though, he’s a hoot.

    I can’t really add to what the guys have said already…

    Things that can affect blade quality sooner than expected:
    * Increase in volume of cut vinyl.
    * Cutting reflective, vinyl due to glass content in the material.
    * Cutting thicker vinyl such as sandblast vinyl.
    * Cutting magnetic panel.
    * Contour cutting lots of laminated print jobs.
    * The quality of the blade will also dictate its life.

    check you have the actual correct blades for your machine. possibly sent the wrong make by your supplier?

    thanks for all the replies and suggestions of what could be the answer to this.

    The blades are Graphtec blades. Could the blades be the wrong type or angle, and if so would they even work?
    The volume of work hasn’t been any more than previous years, i would say about the same and the same type of materials.
    we have been cutting more reflective i guess but not huge amounts.

    Might be worth a call to your blade supplier, Gary?

    If you are going through them this fast, I would tell them what you have posted here and see what they say. might be worth taking a picture of the blade case and any details on the packaging and send also.

    if nothing has really changed for you, then I reckon it’s either the reflective that’s doing it or maybe you have a faulty pack of blades.

    are they brand new or re-sharpened?

    thanks for the reply again rob. no they are not re-sharpened.

    ive decided to just order a set of new blades from Edward Mathias and i will just keep an eye on how i am using them. i will also keep one separately for reflection only and see how these ones go.

    thanks for all the feedback and advice. 🙂

      Tell Edward Mathias that your require one blade for reflective, they can sort you out a special blade just for this media
