It's impressive what the 400w servomotors can do 👍. The machine it's very stable how I see . I'm waiting for more videos with the machine . How much cost a machine like yours?
They are Kurt clones made in CN or Taiwan. In the US they are sold by Shars as "440V CNC Milling Machine Vise" but they are really good quality for the price.
Is it Deci brand spindle? I am thinking about buying similar one. Is it well made with good quality, how is custumer support after buying, does it worth the money they selling for? Sorry for so many questions, just didnt find much information and reviews about this brand.
I didn't finish it ;-) it was just a test cut. The case has been designed by Sebastian End and you can watch his Video, where he makes the final product. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kXOLtAF2MPg.html
@@wmt16 Yes of course but what I mean is if you can bog down the spindle before the machine chatters when you take deep cuts. I went with a 6,5kW spindle to have some reserve
@barrychopsticksThis time I decided to order all mechanical parts with the FS4MG: linear rails, ball screws, way cover, z-axis, table (custom 29mm vs 19mm). All I sourced were the CNC controller parts, servo motors, spindle, vfd, misc small parts and the overall housing.
@@wmt16 wie ist der Mineralguss miteinander verbunden?. Ich möchte mir so eine selber bauen, weis aber nicht wie der obere Teil mit der Basis verbunden ist, man sieht ja oben keine Verschraubung. Wird sie dann von unten angezogen? Würde mich über eine Antwort freuen.
@@nelsone.1472 That really depends on your spindle and what you need to drive it. Analog -10V to 10V or just 0-10V or Step/Dir. In my case I am using Step/Dir to drive the Spindle Amp. LinuxCNC has the PnCConf Wizard - which can help you to build the 7i76e spindle control and if that doesn't work reach out to forum.linuxcnc.org and people will help you.
@@markos3803 I made test cuts in 5083 with 3 flute 8mm endmill: ap=20mm / ae=2.0mm / vf=7000mm/min / n=16000rpm - which is about 100% S1 (5500 Watt) spindle load. About 280cm³/min removal rate.
@@markos3803 At the end the spindle is a compromise between size of the machine, power, rpm, weight and size. I believe a 7.5kW spindle requires a special z-axis, due to it's size/diameter (120mm?), it is also heavier and may require bigger motors / more tuning. I usually don't run the machine at 100% spindle load. 80% - 90% of times I could work with a solid 2.2kW spindle with SVC, but I guess it all depends. To me a 7.5kW spindle calls for a FS3MG.
