Greemech 220

[Mountain man]

Before you alter anvil position etc check that the discs have been sharpened properly, I know of a company ( won't mention names) that carry out re grinds, instead of grinding the angled edge down to sharpen they were grinding off the flat face until the disc was sharp but resulting In the disc becoming thinner. So three re grinds for instance could take 4/5mm off the thickness hence the 6mm gap you now have. You may find that when you put a new disc In the machine the gap is spot on.

Hope this helps

 

Cheers Ropechucka, i'll order a new set of disc/blades Monday (plus anvils or shears as Pete B calls them) ps your inbox is full Pete.

Might as well refurb the whole business end while its apart.

Your welcome mate, good luck with it all. I've got a quadchip and I love it. The GM's are a nice piece of kit.

Merry Xmas bud

ive had the 220 for nearly 5 years, by far the best chipper ive ever owned.

pete B is a good guy and will help you alot

anvil may turn ,if its that typ, rollers will sharpen up ,but be gentl with e grinder as no t to over heat the steel.blades will sharpen , then get a spare set

Interesting!

 

Blade gap should be ideally 2mm

But no one mentioned the most important thing when adjusting blade gaps..

 

Always do it with a New anvil and blades!!!

Even if you take them off afterwards

 

Adjust it with worn blades results in a non standard setting, which also has the hazard of future blade changes result in anvil contact!!

 

 

The anvil on this machine has some degree of wear but still has a little life left, the blades look like they a due a resharpen, feed rollers look like they've been working for a living!

 

I think the blade/anvil gap is looking a little big, big contribution to performance problems helped by dull blades

Which leads me to the question, "how many hours do you get from an anvil"...?

Depends on the operator(s)

 

Regular blade turning/sharpening

 

What wood type is being chipped

 

Is it clean wood (dirt/mud free)

 

Every chipper is slightly different as every operator does it differently !

The first sharp square edge will wear off an anvil quite quickly, best to re-adjust the gap at that point and then it will last a while. I reset the gap on my Heizohack last week to within 1mm before a contract chipping job. I have chipped 300 ton so far. The results have been good. 300 ton is 12 arctic loads, thats a lot of wood, the difference between a <1mm gap and a >5mm gap would be huge in terms of machine wear and diesel used....
