Hey guys haven't had much time to work on mill till this weekend spent most time last week or so doing maint on my lathe. Now should be up n running so ill be making a few mods for both. Alright you Gear Heads have a quick question about gear head mills in how they are supposed to sound when milling.
Recently purchased this mill PM 932. Milled a few things on 6062alum . Over weekend Did some official milling taking some roughing cuts and face milling . This time Primary worked on steels. Not sure of its properties but cuts and looks like a hot roll steel . Found a hunk ,decided to make my first proj from. Btw . Dont laugh at descriptions best I can do via post. With proper feed speed/ Rpm/feed taken no more than .040 Here is what it sounds like. Btw( using ¾ index able tooling 2 flute) W/ TNMG style inserts and also tried RNMG.
I get a nice thump thump thump at the material / tooling however a Grunk grunk grunk sound from the head or up in the column. Is this normal for a gear head type mill ?
Not chatter but a distinct Grunk coming fro the head. Btw I did change some tooling style to see if she quieted down some and she did with a higher speed , but not sure if its a gear head is supposed to be noisy up in the head . Again not a chatter sound but a distinct Grunk grunk grunk sound .Here is my thoughts I suspect the lower the gearing / Rpm the more prominent you may hear this sound so whats your thoughts ? TIA
