G'day Guys
I'm after some advice on what magnetic chuck to by for my surface grinder.
I purchased my grinder used and it did come with a very coarse pole magnetic chuck. I've found however that it's in pretty bad shape with some very large and deep gouges etc (probably have to mill/grind off nearly a 1mm to get clean up) and the magnet barely turns off making parts very hard to remove so i need to replace it..
Most of the parts i grind a fairly small (Less than 50mm long and maybe 3-5mm thick.. I was considering a fine pitch chuck like one of these.
Rectagular Fine Pole Permanent Magnetic Chuck Dia.6"x12" | eBay
This one has a 1/16 pole with 1/32 brass spacers..
These are marketed as being ideal for small thin parts, however how well do they hold on large parts?
Also how well do these fine pitch chucks work with laminated transfer blocks or v blocks? Is there a rule of thumb if the blocks are different pitch? One would assume that the blocks would need an equal to or finer pitch than the chuck in order to transfer the flux lines?
Cheers
