Blade Care

If you want to know how to avoid damage please read on.


If you are not interested we will be happy to take the money you may waste.


BUT WE WON’T

BE THERE

TO HELP YOU

TO WEED

BADLY CUT JOBS!

Illustration of a typical plotter blade magnified approximately 50/1


ALL the cutting is done by the TINY particle
 shown coloured blue


Its actual size is smaller than this full stop  .


It is VERY fragile
and VERY easy
to damage


You won’t be able to see the damage without a microscope.


You won’t know it is damaged until you try to weed a badly cut job.

BACKING

VINYL

With very few exceptions, plotter blades are made from Tungsten Carbide, which, although one of the hardest and most wear resistant materials known to mankind, is also one of the most brittle, especially when it is ground to the very fine edge needed for cutting vinyl and similar materials.


Plotter blades are high precision tools.

We manufacture them, and where appropriate, re-sharpen them accurately to within a few microns, we examine them under a microscope then we carefully protect the tips and put them in a box before we post them to you in a padded envelope.


Despite our efforts, many will be wrecked by careless users before they cut their first piece of vinyl.

Others will be wrecked at the instant of their very first cut.


ALL plotter blades are surprisingly fragile. [not just ours]
It is very easy to damage a blade, not easy to see the damage but very easy to see the result

when you try to weed a badly cut job.

Damage that can only be seen under a microscope can cause a blade to cut badly, or not at all.

If damage [usually chipping] can be seen with unaided sight then it is a total disaster.


Weeding time is expensive - a badly cut job can waste much more than the cost of a blade.


YOUR PLOTTER IS ONLY AS GOOD AS THE BLADE

If you wish to cut accurately and prolong the life of your blades you should to treat them with care.


There is very little more that any blade manufacturer can do to extend blade life but there is much you can do by taking a little care.


Damaged blades cause us no problem whatsoever - they increase our income.

If you are careless - we get more of your money.

We provide this information for YOUR benefit, not ours.

TAKING CARE OF YOUR BLADES


When installing a new blade or Smart Knife in your plotter

ALWAYS start with LOW pressure/force AND DO A TEST CUT.

If the initial cutting pressure is set too high your blade will penetrate the backing paper and be damaged by the cutting strip or roller underneath [this can also damage your plotter].


If you make this mistake the damage is instant, there are no second chances.

Reducing the pressure after the damage has occurred is pointless [so is the blade] which will then cut badly or not at all.


AVOID false economy - using scraps of media with damaged or uneven edges which can “catch” and damage the blade when your plotter is initialising.


DO NOT remove knife assembly from plotter unnecessarily - accidentally touching blades on parts of your plotter during removal and refitting provide opportunities for damage.


DO NOT leave blades unprotected - even when only temporarily removed from plotter.

Blades should always be stored separately with tips protected.


CUTTING TOUGH AND/OR ABRASIVE MATERIALS

Fluorescent, reflective, foil, card, magnetic, polyester, polycarbonate, Lexan, Lexedge, Mylar etc


On some machines you may not need to use a different type of blade but remember that a blade used on these materials will quickly lose the extreme sharpness needed for finer materials.

Use a SEPARATE blade - sometimes - but not always -  a different type - but always separate.


NEVER allow the Cutting Tip of a blade to touch anything  except the material you wish to cut.
