wheel sizes, wheel shapes, motor sizes for metal lathe tools

jeudi 16 avril 2015

Hey,



Written from perspective of setting up to grind metal lathe tool bits.



Would I really notice a huge difference if I upgraded my 20 year old el cheapo 6" ryobi 1/3HP grinder for a 6" grinder with bigger stronger motor ?



How about 8" grinders - are they really worth it - for starters the wheels seem far more expensive.



I think the white wheels are great compared to the grey wheels I got with the grinder.



Do many people use those fancy recessed or the fancy flared cup grinders ? Seems to me that they would make life much easier for getting straight grinds on known angles for metal lathe toolbits but I get the impression that very few people use them.



I also get the impression that lots of people grind on the flat side of conventional wheels despite manufacturers warnings.



Saw this the other day ............. http://ift.tt/1OKok1h



Off down the shops now to ask the same questions.



Bill
