Replacement Metal Cutting Guillotine Blades
Can we supply metal cutting guillotine blades that are of stainless steel cutting quality and don't chip?
1.) For the specific cutting of steels, upto 6mm material thickness, then we recommend your metal cutting guillotine blades are manufactured from Grade D2 material, hardened and tempered to Rockweld 57/58 to give an abrasion resistance, to increases periods between re grinds.
Please Note* Because of the hardness, 57/58 Rockweld, if you then cut stainless steel or durbar, or any other high tensile strength steel with these blades, its quite likely that the blades will chip.
2.) For the specific cutting of stainless steels, then the problem is that stainless steel has a higher tensile strength than a carbon steel, it is this increased tensile strength that creates the problem of blades chipping. To reduce guillotine blade chipping, a solution is to lower the hardend and tempered figures of the guillotine blade to circa Rockweld 55/56, but abrasion resistance is sacrificed.
So, there is no staight forward solution to general mixed metals guillotining.
Harden and temper guillotine blades to Rockweld 57/58 increases abrasion resistance, increases periods between re grinds, but the blade is more likely to chip when cutting stainless steel, dubar or high tensil steels. Harden and temper blades to Rockweld 55/56, then chipping is less of a problem, but abrasion resistance is reduced, shorter periods between blade re grinds are experianced.
3.) For the cutting of mixed carbon steels, stainless steel, durbar, high tensile strength steel above 6mm material thickness, then we recommend your metal cutting guillotine blades are manufactured from ‘Grade 2631 shock resistant steel’ hardend and tempered to Rockweld 57/58 [ chipper quality ]
But again these shock resistant blades have a down side, this being that this grade of steel quickly looses its crisp sharpness, therefore whilst your metal cutting guillotines cutting capacity range indicates that you can go down to 22 swg or 18swg etc, the lack of a good crisp sharp edge may prove to make the guillotine not suitable for cutting of such thinner materials

Turn Guillotine Blades | Re Grind Guillotine Blades
Replacement guillotine blades of UK manufacture.
Our service team turn guillotine blades to a new sharp edge, if no sharp edges left, we remove and re grind metal cutting guillotine blades> If the metal cutting guillotine blades have serious defects i.e. chips, cracks etc, or they have been re ground several times [ see below] then we can supply a set of replacement guillotine blades.
We aim to keep your metal cutting guillotine blades in a sharp effective and reliable condition.
- Our service team will visit your workshop, assess the guillotine blades condition, sharp or blunt, chipped or cracked, if blade(s) have a good sharp edge, chip free, then our service team engineer will turn each blade to the new sharp edge, then re set the blade gap between the top & bottom guillotine blades.
If the guillotine blades have no good sharp edges or they are badly chipped, but are of a correct thickness, then we will remove the guillotine blades, arrange for them to be re ground, once the guillotine blades are re ground, a member of our service team will re visit your workshop, to re fit the guillotine blades, re set the cutting gap, make test cuts for your approval.
Our basic principles with regard to re grinding guillotine blades are :
- We do not recommend a reduction of a metal cutting guillotine blade thickness by any more than ( –) 1 mm, from the original
manufactured thickness dimension.
The reason for this is because, there is, (a) limited guillotine blade gap adjustment,
(b) the guillotine blade sits upon a machined seating, if packing pieces are put in place behind the guillotine blade to compensate for the reduced guillotine blade thickness, this then positions the guillotine blade at the edge of the machined seating, or possibly off this machined seating and all cutting forces are placed upon the guillotine blades fixing bolts. - We do not recommend grinding a guillotine blades ‘width’ to remove chips, a reduced guillotine blade ‘width’, often requires the fitting of packing pieces between the guillotine blade edge and the machined seating, the packing pieces sometimes snag during cutting, or the packing pieces may eventually work loose and come out, if they come out, then the none supported section of the shear blade may crack during cutting.
These are our recommendations, however you may have a different opinion,
we will work according to your instructions
In the event that the metal cutting guillotine blades are badly chipped, or have been re ground to a point where we advise that they need replacing, then we can supply replacement guillotine blades.
