CNC Post-Processor Development with CAM-POST ICAM From 3 Axis Mills to 5 Axis. I have a 25 mm centercutting EM, but am almost afraid to use it after losing the two 17mm versions. Take a high-end 5 Axis Japanese machine, that might cost 500,000 fully. The centercutting toroidal is tough and does a good job. I just don't think that the design has enough meat to be robust to the less than perfect programmer/set-up tactician LOL. They both failed at the threads at the slightest of mistakes (chatter from a loose fixture bolt and a bit aggressive WOC). Toroid is great for finishing flat surfaces and pocket floors that need a corner radius.ģ/8" 90 Degree End Mill APKT Insert - Indexable Milling - Indexable Cutting - ProductsI too have blown up 2 of the 17 mm centercutting EM's. The centercutting EM is my goto tool for roughing aluminum. Keep in mind fly cutters are designed for light cuts to achieve super surface finishing, so they typically cut shallow depths. I have Tormach's modular insert setup with the 25mm Centercutting EM and 25mm Toroid EM. Depends on material of workpiece, For metals max:0.07874 inches (2mm), for plastics and aluminum max:0.15748 inches(4mm) can be good starting point. I will still use the first 17mm EM with just the vertical insert.įYI, Shars sells a 3/8" single insert endmill.ģ/8" 90 Degree End Mill APKT Insert - Indexable Milling - Indexable Cutting - Products Originally an end mill was used to remove material using only the cutting flutes. It had started rattling, not chatter, and about 20 seconds later it went "clunk" and I found the endmill sitting on top of the part, holder still in the spindle with the twisted off thread in it. For an extremely basic answer, an end mill is rotated in the spindle of a milling machine and moved against a piece of material (metal or otherwise) and the rotating ‘blades’ on the edge of the tool will slice away material to produce the desired form or shape. This one was not my fault, no part pullout, it just snapped off at the base of the thread. I bought a second one and a few weeks ago it also failed. The land for the horizontal insert was bent so the insert won't sit correctly. I had a part pull out of a fixture (my fault), the inserts broke as expected but the tool was destroyed as well. The 17mm EM works good but is not very robust. I also have the same setup in the smaller size, 17mm Centercutting EM and 16mm Toroid EM. Toroid is great for finishing flat surfaces and pocket floors that need a corner radius. Sent from my SM-G900V using TapatalkI have Tormach's modular insert setup with the 25mm Centercutting EM and 25mm Toroid EM. ![]() What kind of insert em's do you have, how do you like them? I'm thinking about trying a 3/8in if I can find one, preferably single insert. ![]()
