glass cutting by milling
hello
i am designing a small cnc flat glass milling glass cutter.(non straight lines).
the glass is 8 mm thick (medium thickness anchored with vacuum nipples).
i am going to use 14 mm diamond coated milling bit. high speed water cooled 4 segments.
i have to choose the right spindle speed and minimum torque to achieve best results.
from that - i will choose the right motor and upgrade sprockets (with belt).
can anyone think of which is the right minimum torque necessary on 25K rpm ?
what is typical motor type (power , drive, that is used in such setups.)
important is small scale size , and low noise of operation.
i know these bit are used in high power milling units (which i definitely not need in my case - its an overkill)
thanks folks for any bit of info you can contribute here.
Oded.

Re: glass cutting by milling
I use 14 mm diamond tooling (core drills actually) on granite and basalt. They are harder than glass. Water cooling is imperative. It sprays around.
My max spin is ~3,200 rpm. Power required at that spin might be 200 - 300 W.
At 25 krpm most of your power will be going into the bearings, not the cutter. You will probably need to cool the motor/spindle.
Noise - some, but not at the ear muffs level.
Cheers
Roger
