Buy Lapidary
Buy opal cutting lapidary direct from importer or
manufactures
Opal cutting factories or hobbyists need full range of
lapidary gear to cut and polish their opal rough
After the miner has his rough the first stage is to saw the
rough .Most opal cutting factories near the opal mine will have large saw
blades to cut the rock into manageable pieces ,so most cutters will need 6 inch
saw blades as most lapidary cutting machines are made for this size
0.30 thicknesses is good for first cuts but when you get
down to actual opal colour to slice you really need thin bar 0.12 to0.18 or
even thinner but these can be expensive
Thicker saws tend to chip opal colour so best to keep one
saw for rough and one saw for slicing opals or more delicate work.
Mini saw blades are also on dremel drills and these should only
be used for drilling out sandy potch or
cutting this piece off a slab.
After dobbing than move onto diamond grinding wheels and Diamond Pacific has good reputation
with diamond grinding or resin bond polishing wheels in different grits .A six
wheeler cutting machines with good water
flow can start with grinding wheel 220
or 360 600 grit ,and polishing
wheels 1200,3000,8000 grit. Chinese imports
wheels are cheap but these wheels do not last long and many fall apart with
very little use.
For boulder opals cutters use lot dremel work and diamond coated
drills are popular ,especially 30 piece rotary
Burr set so covers all sizes you need to drill into opals and make sure you use
plenty water drilling into boulder opals. Next stage is resin coasted drills
which are also diamond impregnated in different grits
