facet cutting speed
« on: August 28, 2019, 10:57:31 AM »
Hi looking to purchase a new motor and speed controller for my gf3 faceting machine looking at a 120 watt 240 volt one but top rpm's are 1350 my question is this a fast enough speed for cutting?.I also have the option of a 120 watt 12 volt dc 3000rpm one buy then have to source a converter to run on 240 volts any help on whether 1350 rpms's is fast enough for cutting or not would greatly be appreciated.

What pulleys has the machine got, if it is stepping down you may need more rpm. At 1:1 it might do. 
A slightly more powerful motor might be good aswell as my machine with a stardard 120watt 240v motor is underpowered imo.Lots of motors on ebay/aliexpress.

Not sure if you'd need a more powerful motor than the 120 watt one. I suppose it depends on what your cutting and how fast you want to cut. I notice that in the latest 'Facet talk',  Horst Ricker is quoted as replacing a motor in a Hall 2000 with a 120 watt 12 volt motor. Horst as you know is a gun with this sort of thing and if it's good enough for him, I would suggest that it should be OK. As far as the speed goes, I would suggest that the slower one should be OK. Gemcuts in NSW are apparently converting GF4 and GF5s to 12 volt, might be worth giving them a ring to find out what RPM they are using.
Common sense isn't exactly common
