Engraving Granite?

[debogus]

Coltoncustoms nice work on your page .

Ive only done one on natural suface ( at least the client liked it) it turned out all right. Usually on smooth slab

Did this one with hartco, the only one that sales let me create myself.
Thats the problem of working for others.

Back splash behind a stove.

yes a laser will do the job however i have found that with my 100 watt it will not burn into the surface very far i am impliying that one can apply the mask to the stone and then use the laser to cut the mask due to you being able to cut fine detail with the laser as it is a pain to weed it with a plotter, and then the image can be abrasive blasted into the stone to achieve a deeper image

also looks great hartco sells a good product and i understand working for others i did a project here that they charge 1.1 million for and payed me 12 dollars and hour to do hence the reason i am self employed smooth slab is definitely the easiest if you ever try a rough slab and need help let me know after 7 years i have definitely screwed some up and now know the tricks

Call Gran Quartz stone tooling in GA. They have a CNC specialist there that actually taught me alot of what I know. He does nothing but develop router bits for the stone industry. Ask for a vacuum brazed engaving bit. Simliar to electroplating except with much stronger diamonds..it is the closest thing in that size, to sintering. A sintered tool is the ideal technology for most stone work marble and granite alike

Diamond tools are fine for grinding and shaping granite, but for lettering you either Sandblast which is mostly used today for the speed of which the work can be turned out not the quality!, the bottom of the letters will be rough, so if you want a good quality Vee Cut letter have a look at these sites sorry they are not american but they do sell the proper bits needed for engraving on granite, they are also used dry with a Vacum for the dust

if you work within .25 inches engraving can be done with carbide bits in .125 inch steps.I do all mine with them but if i have to go deeper i use diamond conical shape bit
works real well with marble too all are done 5000rpm 15i/m feed rate
