For faster removal rate, smoother finish, lower impact on the part and spindle bearings, less rattle & chatter plus improved safety use these tips. Set the cutter just wider than the part, this allows the tool to smoothly engage at a tangent by gradually increasing the tip engagement. This gives much less impact & is far quieter. Having this minimum cutting radius allows for faster spindle speed & ultimately faster metal removal rate. The protruding toolbit becomes invisible when running so is much safer when close to the cutter body. If the tool is cut shorter then there wont be the other end spinning outside the cutter body. Can you please explain why the tool is tilted at an angle, if it was flat to the bed the insert edge would still be the lowest point. I think cutting the tool on an angle is a leftover idea for when there were flat HSS toolbits. With the insert protruding beyond the toolholder body on insert tools you are using, is this angle required?
I 'm just about building my own milling machine. I'm lucky to got my hands an old "Heckert Kopierfräsmaschine". Hence the spindle and the whole spindle moving machanism is missing- I try to build a new spindle holding and positioning thingy and fit a 4kw china-spindle to it. I've learnt alot from your concept to mount the spindle. I hope to be able to copy that on my setup. I think this is a very versatile machine for all thinkable jobs in a small workshop. 👍
@@wastelandworkshop3839I have installed the spindle at the weekend. What a beast - and heavy as well. The spindel mount is made from 80x80 rectangular steel pipe with 6mm wall thickness. Quite sturdy. I'm very pleased with the result. There is only one thing that's not good - the spindle speed. It is running at 18000rpm at the highest. Lowest speed is 6000 rpm. This is much too fast for tools like flycutters as yours for milling steel. I'm still searching for an affordable SK30 spindle with drive shaft to be able to reduce the speed down to 'normal' milling rpm. If anyone here has a tip for me - you're welcome.
Thanks :D I just thaught "what's the most random thing i can put at the end of the video" The sandwich i'am eating is actually a bosna. That's like a hotdog but with Bratwurst sausages, onions, a lot of curry powder, tomato ketchup, mayo and a bit of mustard. Personally i like to use baguette as bread. Thanks for watching the video to the end!
What is your background? Are you an engineer? I'm currently dallying around in metal work. I have bought a small mill, but really overestimated its capacity, so now i'm making a a mill like yours. Would be cool to have a quill in the head though. Anyway. Love the projects.
Thank you very much! Yeah i am a mechanical engineer. Currently i work for a company that produces big industrial shredders. It's great that you already got a mill. I bet it will help you a lot when building a bigger one. Would love to see how yours turns out! You are right. A quill would be very helpful. But that was unachievable with the tools i had at the time. Thanks again for the comment :)
He would severely limit his reach when speaking German. I am Dutch and would probably not have finished the video if it had been in German. I like seeing the new mill producing parts. Cool stuff. Keep it up.
