Surface Grinder info?
Surface Grinder info?
(OP)
I need a surface grinder to resharpen woodchipper blades.
I hope someone might be able to point me in the right direction...
They are up to 20cm long 7mm thick,obviously they need to be kept cool.The angle needs to be exact, 42degrees for example.
Ground on a hollow grind disk in a smooth horizontal motion.
Would a jones and shipman machine be suffice?What model/modifications etc?Budget of £1000
Apologies for my ignorance..Any help would be much appreciated
Attached is the closest machine I'v found but runs at £8k

ornerynorsk- A valid point but no they aren't to be hollow ground-Hollow grinding does cut better but it won't keep its edge for as long..
Will that make any difference as to machine choice?
unclesyd-I was thinking about making a complete jig around a bench grinder,but that may take a while...

As to the model/size/type of the machine, drop into a machinery dealer and see what's available to your locality. You'll want one with coolant, as you mentioned in your original posting.

the direction that the grinding marks lay on the finished piece will make a substantial difference in how long the knives stay sharp -- if you "burn" the knives you will really kill you tool life
Good luck it sounds like and "interesting" project
