@DeltaCon said in Need your advice, V-Slot VS Linear Rail.:
Huge CNC machines tend to move and accelerate a lot less fast, that may contribute to that.
only during the cut, not during the move, since they are normally much larger the G0 need to be fast .. mine are not some super fast machines (G0 moves at 300mm/sec or F18000, limit is F20000) but I worked on beasts that are much faster.. original hiwin is very quiet .. for e.g. on one of my machines I had X on the 4 25mm rods and linear bearings (original SKF, preloaded, yadayada..) when I converted that to hiwin rail, it's night & day ... now, for e.g. I had a carriege failure after some tens of thousands of operating hours and I purchased locally a new carriage, it was sold as original but was a PRC copy, fitt was nice and behaved like original but was loud .. no matter how much grease we pumped in the noise was ... uh .. so I brought one from germany a month later, noise stopped immediately ..
I know some ppl locally that go purchase PRC linear rails, take all the balls out and into trash (actually they give the balls to local knife makers but irrelevant) and purchase new balls from sweden/germany and say they get precission and smoothness and silence of original rails at half the cost of original ones .. I never tried so can't confirm, sounds interesting for sure
