Click request price for more information. Located in Turkey and other countries. Good condition DMG Mori DMU 65 MONOBLOCK Machining Centers available between 20 years. Control: Siemens available. DMG Mori DMU 65 MONOBLOCK Machining Center.I've had issues in the past with plunge entries stalling the spindle, but I've since started using a ramp entry, 2 degrees, which on occasion still produces enough load to hang me up. 030" ADOC, 250ipm (.0494 ipt)(668sfm) in hot rolled steel. The most recent cut to stall the machine went as follows: Cutter: Dapra 2" 5fl button cutter, 1.2" RDOC. I'm seeing this issue with our 2" roughing shell mills. Machine: DMG MORI DMU 65 monoBLOCK.I run a 5 axis DMG DMU 65 monoblock, and have recently run into some issues with overloading my spindle with cuts we consider gospel at my shop.
![]() Next step would be to install a monitor on the transformer that tracks input off the 3 phase power supply.DMG Mori is a worldwide leader of machine tools for turning and milling. This was not the case, I was able to run the spindle up to the 18000 rpm maximum without issue. He said due to DMG's inherent sensitivity to power input, a drastic increase in power to the spindle could produce a variation of input large enough to fault the machine, regardless of whether its cutting or not. I previously ran the shop's DMG DMU 95 monoblock which has available another 15 lb.-ft of torque, and never ran into this problem. I've had issues in the past with plunge entries stalling the spindle, but I've since started using a ramp entry, 2 degrees, which on occasion still produces enough load to hang me up. 030" ADOC, 250ipm (.0494 ipt)(668sfm) in hot rolled steel. The most recent cut to stall the machine went as follows: Cutter: Dapra 2" 5fl button cutter, 1.2" RDOC. I'm seeing this issue with our 2" roughing shell mills. We look forward to helping you find the used DMG Mori machine that best suits your needs.I run a 5 axis DMG DMU 65 monoblock, and have recently run into some issues with overloading my spindle with cuts we consider gospel at my shop. Dmg Dmu 65 Free To CommentFrom DMG DMU 95 monoblock to DMG DMU 65 monoblock,Makino did a really pretty good webinar on this fairly recently,Basically matching or understanding MTB spindle torque curves and attempt to match it to calculated cutting conditions.They had a few useful equations at the end to kinda reverse engineer what can happen.“Roughing It” Live Event – Why Your Machine’s HP Chart Can Increase Throughput | Makino^^^ Hour long webinar from . + machine rigidity being an issue (potentially) unless a completely different cutting strategy is required.Which spindle / are you using ? , I could probably dig up torque curve for + spindle ~ basically your 15ft lbs torque delta. 030" ADOC, 250ipm (.0494 ipt)( 668sfm) in hot rolled steelSo seems the rpm in this case would be really low / needs not quite monster-ish torque but below a certain rpm certain machines would just "shut it down". Thoughts? Feel free to comment with further questions if it'll shine more light on the issue.I'm probably going to have to convert this to metric (for me lol),Cutter: Dapra 2" 5fl button cutter, 1.2" RDOC. I'm 3 years into the trade and love to hear from folks who know way more than I do. This was not the case, I was able to run the spindle up to the 18000 rpm maximum without issue. He said due to DMG's inherent sensitivity to power input, a drastic increase in power to the spindle could produce a variation of input large enough to fault the machine, regardless of whether its cutting or not. The app engineer recommended going from a dead stop up to RPM ranges that tickle the spindle's maximum speed. I run a TNC 640 controller, and almost always have a live line graph displaying vibration/load up on the monitor, though needless to say I was away from my mill this last time around so can't tell you if there was a considerable spike in harmonics. This issue is so sporadic that I cant replicate it on command. He mentioned that its possible that the electrician set the output from the transformer close enough to the machine's threshold that even a small deviation in current could fault the mill. Specific cutting conditions materials and tools / inserts used (perhaps) fixtures etc.Maybe tomorrow (time willing) I or anyone else can reverse engineer the cut the other way , maybe in terms of MRR and various co-factors (K-values) - usually supplied by specific tool manufacturers for given or supposed materials.Might not actually be the machine per se.I know the DMG Mori machines have a lot of spindle protection, so a bit like what was saying maybe vibration in cut ?. (theoretically).So theoretically that spindle should (assuming it has at least 1/2 the low end "Umpf" of a DMU 50 3rd gen and other 20K speedmaster spindles), your spindle should not be stalling unless something odd is happening in cut. I don't have those + for the year that you have.For example the DMU 50 3rd gen 20K rpm "SPEEDMASTER" - spindle,So that seems to come out around 30 ft lbs or approximately 50% of spindle output - "S1" at 1200 rpm.1/2 way inside supposed safest limits for continuous running. Is premiere pro for mac and windows the sameThat webinar is really good! been using the same formulas for awhile, always baffles me how/why people dont optimize their parameters for the tools available. - > 46 Horse Power (nominally)) at max power output).I'm probably going to have to convert this to metric (for me lol),* Actually Peter Zelinski editor in chief for Modern Machine Shop (Magazine).
