Oljni brusni kamen

[direktx]

Pozdravljeni

Kje v Sloveniji bi se dalo dobit oljne brusne kamne za brušenje ročnega orodja?

Rabil bi granulacije 8000 6000 4000 2000 1000.

Hvala

Kaj pa smatraš pod orodje?
Za nože sekire dleta...... je povsem dosti če imaš samo 2 kamna. Za primarno grobo popravilo pa kak diamant.

Kot orodje imam v mislih:

Dleta
Rezila od ročnih obličev
Rezila od električnih obličev
Noži
Sekire

Na splošno bolj orodje za obdelavo lesa.

Za kakovstno ostrenje je potrebno imeti več kot dve različni granulaciji.

Alternativa kamnom je recimo brusni papir prilepljen na steklo.
Druga alternativa so vodni brusni kamni.

Na tej spletni stani sem si malo ogledal brusne kamne, saj ravno potrebujem novega.
Glede na vaše izkušnje me zanima kakšno granulacijo priporočate. Sedaj imam doma kombiniranega grobo-fino, ki pa je že kar v letih(obrabljen), oznaka granulacije pa ni vidna.
Brusil bom kuhinjske nože...

Mislim, da sta dva kamna več kot dovolj. Bolje, da sta dva in ta kvalitetna. Jaz ima Chosera Naniwa 1000 in 5000 granulacijo. Vmesne granulacije enostavno ne rabiš, saj oba odvzemata precej v redu. Nad 5k bi šel brusit samo še britvice . Za to kar rabim, pa verjemi da cenim ostro orodje, je pa več kot dovolj. To sta kvalitetna in posledično tudi draga kamna. Če z orodjem ne delaš kot svinja z mehom, potem na nižjo granulacijo ne boš šel nikoli saj ni potrebe. Imam pa še ravnalno ploščo za kamen kar je tudi pomembno da maš.
Ko sem nabavljal sem vzel še Naniva superstone 400 za res sklumpano orodje. Ta je nižji cenovni rang kamna. Z njim nisem zadovoljen saj se hitro obrablja in slabo odvzema. V priliki bom kupil raven grob diamant, ki ga bom koristil za ravnanje rezil. Problem je, ker je novo orodje precej šlampasto zabrušeno.

In to je to, pa še to bo najbrž preveč drago.

Za navadnega smrtnika je granulacija nadpovprečna. Kakšna je pa kvaliteta kamna pa ne znam povedat saj ga nimam. Obstaja tudi kamen od kitajčkov, če se prav spomnim Norton, kateri baje tudi niso slabi glede na ceno. Mal pobrskaj po internetu. Teh debat o kamnih je res ogromno, preveč. Tisti s fetišem na kamne odštejejo krepko prek 1k evrov.

Moj predlog bi bil da vzamete kombiniran kamen z granulacijo 240 in 1000. Z 240 odstranite poškodbe s 1000 pa naredite ostrino. Z višjimi granulacijami se potem ostrino še izboljšuje/polira.
Alternativa je da uporabite vodobrusni papir na steklu, ki da primerljive rezultate a manj užitkov pri brušenju.

Which waterstone should I choose?


Japanese Waterstones - both natural and synthetic - are known for their quick-working qualities, not only for Japanese tools, but also for their Western equivalents. The small particles that do the cutting are loosely bound together in the stone, and so during sharpening, the surface particles are quickly washed out, allowing new, sharp, particles to start working on the blade. These waterstones must be lubricated only with water! Never use oil!

Our large selection of stones will allow the connoisseur to find, from among the many famous manufacturers, the ideal stone for their need. Because every manufacturer formulates their stones to emphasize a different mix of qualities, and those qualities can vary widely between the different stones, for an optimal sharpening stone set, most woodworkers need stones from several different companies. If one gets to know the characteristics of certain types of stones, sometimes one producer will provide all the stones one needs, and in some cases that can be an advantage. But there is no correct solution for any situation: the stones must fit one's need and work style.

On the other hand, such a large selection can make it hard to choose a workable combination, and so we offer this small guide to assist you to make at least a good beginning.
First to the different manufactures:

Matsunaga, which produces the brands KING and SUN TIGER is perhaps the best-known manufacturer in Europe. Its strongpoint is producing very traditional soft stones that abrade quickly to reveal new sharp cutting particles. These kinds of stones must be dressed very often to keep them flat and effective.

The CERAX-Stones from Suehiro are a little harder, and so are not worn down as quickly as with the classic Japanese water stones. With the 8,000 grain stone, one can obtain perhaps the best-cutting edge with a mirror polish on chisels and similar blades. Suehiro also makes a small combination stone for those who do not sharpen tools all that often and are hesitant to spend so much for a CERAX stone.

The stones from SHAPTON are probably the hardest Japanese sharpening stone of all. They will remain flat for a long time, and so when one is looking for a relatively coarse stone to cut quickly without needing flattening very often, these are probably the best choice. The finer-grained stones also work very well. But the SHAPTON stones do not provide the mirror surface the softer stones can.

The biggest advantage of the NANIWA-Stones lies above all in their fine-grained waterstones. With no other stones can one achieve as perfect a mirror polish.
Which stone for what use?

For rough sharpening - to grind off chips in the edge or for when the blade is unusually dull -- stones from 120 to 400 grain are called for. We recommend stones with a grain between 120 and 240 in this case.

For normal sharpening, stones between 700 and 2000 grain are used. We recommend stones between 700 and 1200 grain.

To take off the fine scratches and the burr left by coarser stones, and polish the surface, one can use stones starting around 2000 grain. Above that there is theoretically no upper limit, but at the same time stones above about 10000 provide no measurable practical improvement in the edge. It is also interesting to note that above 8000 grit, there is no Japanese measurement standard. With all the stones labelled as having a finer grit, one simply has to take the manufacturer's word for it.

For those who have reasonable experience with sharpening, we recommend a finish stone of 8000 grit. If one is not certain, or for beginners, stones with a grit between 3000 and 6000 will produce acceptable results.

So, in principle one needs at least three stones if one has to do significant amounts of sharpening. One to grind, one to sharpen and one to hone.

For someone who sharpens blades only occasionally, and knows that they will not need to grind out a chip in the edge of the blade, for instance, a combination stone will suffice. The size that one chooses depends mostly on a trade off between cost and speed. The bigger the stone, the faster one can work. The smaller stones work just as well, they just take a little more time.
How much money do I have to spend?

There are many different possibilities to assemble a good sharpening set for every use and budget. You can have a beginner set of 3 stones for less than 50 Euros or a professional set for more than 300 Euros.

Cena je dobra je še mene zamikalo.

V Nemčiji je primerljiva kombinacija:

NANIWA Super-Combination Stone grain size 800/5000
Super stone series
for sharpening and honing
Now you can have the Naniwa Superstones’ quality in a combination stone. The only disadvantage to this, in common with all other combination stones, is that you have in every grit size only one surface to work with, and so one must resurface hollowed stones more often. Because of the slightly different working qualities of the Naniwa stones, the nominal grit size, 800/5000, of this stone is more comparable to the classic 1000/6000 sharpening-honing combination.

Za ravnanje brusnega kamna lahko uporabiš brusni papir in steklo.

Če si se zapičil v Naniwa in če kamne rabiš pogosto potem vzemi Chosero in ne Superstone. Jaz z Superstone 400 nisem zadovoljen. Je kot dan in noč. Chosera je debelejši in se precej manj obrablja in bolje brusi. Če gledaš cena/učinek je Chosera bolj ugodna. Jaz sem kamne vzel pri osterrob-u. Za primerno ceno pa se poskusi zmenit.
Samo še tole. Če boš kupil sintetični kamen pazi, da ga ne boš slučajno namakal in puščal v vodi, ker bi ga tako uničil. Po uporabi jih obriši in shrani na suhem.

Povsem možno. Bom probal enkrat.
