Re: [Emc-users] ? cutting a square carbon fiber tube ?

The Stanley 20-800 should do the job. Apparently Home Despot has discontinued selling that one, or any other hand powered precision miter box / saw. It's either the cheap plastic crap that can't cut a decent angle or the big power circular saws that cut out huge kerfs and are no good for

Re: [Emc-users] Deep slot chip removal

If possible, I like to use a tool 1/2-1/3 of the width of the slot and use a HSM style milling path. I've cut 3/4" deep in a single pass in aluminum using a 1/4" bit to make a 1/2" wide slot this way. A strong air blast or flood coolant is essential to clear the chips. Used FreeCAD to

Re: [Emc-users] Deep slot chip removal

Yes, you should mill slots with a slightly smaller cutter and cut slightly undersize. Then cut to the finished dimensions. That way during the finish pass only one side of the cutter is touching the work. Chips should be removed before the finish pass. Some people make one or two 'spring

Spinlde size is around 8-9kW but currently limited to about 1/4 of the torque. 12mm tool milling a slot same with as tool. Changed program and will predrill thru holes first to help chip evacuation. This will solve the problem for this time but guess this is not the last time I machine a deep

Flood coolant, air blowing, or vacuum. Or pre-drill a bunch of holes to almost finished depth to remove the majority of the waste before milling. On Wednesday, November 30, 2022 at 10:08:49 AM MST, Nicklas SB Karlsson wrote: Milling a deep pocket spiral down work great first turn but after
