2.2Kw 3PH ER20 spindle came from Shanghai China in 5 days! This thing is a beast, and weighs around 10-12 lbs. Nothing fancy with regard to finish but it’s not too bad. Big discussion here on these Cheap Chinese Spindles on cnc-zone. Working on redesigning the spindle mount now. The servos we ordered today from Hui Li at dmm-tech.com and should be here next week from Canada. Tim and I did some measurements and it looks like I’ll be able to use the same 8mm pulley and axis motor brake on the new 300W z-axis servo. That saves me a couple hundred dollars!
Motors are in!
