Soda Lime Glass

[lamlinh]

Hi All,

 

My customer provides me material: Soda Lime Glass- 2" Dia x .05 thick. He wants me to make .1 hole at center of material by next week, however I have not machined this material before. Could someone points me a direction how to hold the material, Feed rate and RPm. Any input will be appriciated.

 

Thanks.

Try this.

 

you will need a .100 od brass tube, diamond lapping compound, one jack off drill chuck, model clay, and a bridgeport.

back up your glass with some tool steel so you don't break through.

chuck up the tube, build a moat around the drill location, fill moat with diamond compound and water.

start at 500 rpm

do not make heat

it will start slow until the diamond is embedded in the brass.

then "drill baby drill"

hope that helps.

Thank your inputs. I want to make my statement more clear. I have .1 diamond drill tub already. .1 dia hole at the center of material is through and I use Haas machine without coolant through spindle.

 

Thank.

35K chipper is suggesting the best way IMHO; on the Bridgeport at least you'll have some feel as too if it is cutting or not.

If your set on using the Haas flood cool and feed real slow, on the haas you can always overide up to %1000 i think.
