Machine Grade Fused Silica Lubrication
Machine Grade Fused Silica Lubrication
(OP)
I'm designing a direct chill tilt-pour casting mold. Fused silica will be used for part of the mold. I have found a supplier of machine grade fused silica. I personally have never machined a ceramic and our machine shop also has close to nil experience. What is the extent of the lubrication that is required. Is spraying a continuous stream okay or should flooding be used? The manufacture says use 'lots' of lubrication or risk chipping the part. Thanks for any input. The raw material isn't cheap and I would hate to ruin a part for lack of proper lubrication. Thanks.

Interestingly enough, the data sheet says the ceramic can be machined with carbide tip tools as long as there is plenty of lubrication. I'm assuming this goes for both cutting and drilling operations.
