Heidelberg Windmill 13x18 die-cutting plate thickness

I was kind of thinking that there is one plate thickness for die-cutting. But when I’ve decide to buy a spare for my plate (that work really long time) I noticed that there are: 0,5 mm, 2mm, 2.5 mm, 3mm thicknesses.
What’s the difference? Which one to use as “basic” (parts book doesn’t give a clue)? My guess is those 0.5 mm is for greasing.
Any info appreciated.

M M D Friend, just done a little investigating re your cutting jacket, one supplier here in U.K. who are quite helpful, state that they only supply one thickness for both, the 10 x 15 and the 13 x 18 H/berg Platens @ 0.8 (zero point eight) M/M thickness.??? … They quote £110 sterling, U.K. for the 10 x 15 = approximately 1,485 Ukraine Hryvnia, and £120 sterling U.K. for the 13 x 18 = approximately 1,620 Ukraine Hryvnia, but in both cases, PLUS U.K. V.A.T. and Delivery.
This info may help, in your enquiries, if not apologies???

???The Company, Very helpful, even if you do not purchase, Listed on the W.W.W. as *Impression Works* Leeds, Yorkshire, U.K.???

Thank You Mick!
I’ve also made some research :) and came to interesting results.
Actually there are 2 types of plates - the so called “bed” plate and “cutting” plate. First are 0.5-0.8 mm, second are 2-3 mm.
BTW Bar-Plate site was very helpfull (to say the truth got the same information from 2 different UK suppliers - not the one You’ve stated)
So the question is still open. Additionally what’s the difference between bed and cutting plate?

M M D Sir, my ramblings are just that, ramblings rubbish by another name and apart from calling up the company as above, my only experience was limited to making 3-4 CUTTING, plates/jackets for 2 different machines, Firstly for a Thompson British Auto Platen, slightly bigger but close to the 10 x 15 H/berg Platen, secondly for An Arab (British) Platen, originally treadle but often converted to Power, but hand fed. and now very sought after.??
In both cases, with an original cutting plate from The Thomson, (which had been badly ill treated with cutting formes and too much packing and/or impression) I took the original plate, to our metal suppliers, and requested the nearest thickness to the pattern, which was exactly matched!! . . With the Arab I had no pattern so I took the same thickness as for the Thompson, and by pure luck, more than any knowledge or judgement, was successful in both cases, I used that which I was offered, and by todays standard, would have been slightly less than .05 m/m .
My only factual up to date is as above re-quoted from our Graphic suppliers.
But it appears now that you may have been given more comprehensive, (but Good Sales talk) info, regarding and including *Bed Plates* bed plates, as I understand,! would normally be regarded, as the plates that you would put on a proof press to bring your type matter up to the same height, to print,! as if it were on a galley, also possibly, the term bed plate would be used in the context of an auxiliary plate used on a bigger cylinder machine, to achieve the correct height, after the bed had been ground back, to achieve accurate results, or, the expression would be used, by the machine minder when putting a plate, behind the cutting form, to protect the actual bed, because although the cutting rule has a keen edge to cut, the underside is, (even at 2 point thick) still liable to damage the bed, under sustained impression,
These precise results/damage, can be seen on Briar Press when shots are posted, looking for the serial number, of various machines, frequently stamped into the bed!!!
The above is only my understanding of Cutting Plate or Cutting Jacket versus Bed Plate, in No Way offered as FACTS… . Good Luck Mick

Good evening depending on the machine depends on the cutting plates heidelberg made several 13x18 platens
Printers GT , die cutters GTS ,hot block toilers GTP
GTS and GTP were designed with a lower ground platen face the we’re supplied with different cutting plates. These can be identified by the three counter suck holes in the cutting plate and these do come in 3 sizes. Also a standard cutting plate for GT can be identified by the two lugs that are on the bottom
If you are unsure please feel to ring us on 01924230800 and we can work out your heights

With regards your post the cutting plates the are in 3 different sizes 2mm 2.5mm 3mm these are designed to go with a certain cutting form height .
Heidelberg made these interchangeable so a trade finisher can run customers forms depending on height again these were used on the GTP from hot block foiling to die cutting hot foiling required a lower plate to die cutting
The thinner cutting plates are designed to clip onto a standard GT and fixed with a small grub screw and clip into your existing tinpin bar clips at the top these are commenly used on printers the heights of these vary from different suppliers .
