Hi All,
I'm looking for some advice from all you guys out there who may have looked into the cheap Chinese spindles that are available in alliexpress or on alibaba.
I want to upgrade my current scratch built machine so I can machine steel effectively and just to improve my surface finish on aluminium and plastics. An added bonus if I get a BT30 taper will be the ability to make an Auto Tool Changer later on down the track. :-)
I'm currently running:
-ER16 cartridge spindle from Sherline.
-1.1Kw (1.5hp) 3 phase motor - vbelt driven to the spindle
-Danfoss Micro VFD
-Mach 3 with Ethernet smoothstepper and CNC4PC breakout boards.
-gecko drives for XYZ axis
I plan to make a new Zaxis head assembly around a cartridge style BT30 spindle.
Has anyone got any recommendations on who to get these spindles through? Or any warnings or experiences about ordering them?
I'm looking at:

or something similar. Although I would prefer something with a spindle speed rated at 10,000rpm or higher.
Any suggestions welcome.
Thanks in advance.
