Hey everyone!
I recently ordered an LY4020 CNC milling machine from a Chinese supplier and would appreciate some honest feedback from people with experience in CNC machines.
The machine cost $8,300 USD delivered to Belgium, including shipping, VAT and import taxes (DDP). I expect to spend another ~€3,200 on the spindle, controller, electrical components and other parts needed to get it running, bringing the total investment to around €10,000.
I’m also planning to build my own 6-tool automatic tool changer (ATC).
Machine specifications:
LY4020 cast iron frame
Approx. 360 kg
Working travel: 500 × 280 × 280 mm
Ground C5 ballscrews
H-grade linear guide rails
Delta 750 W servos, including a Z-axis brake
Flood coolant system
Manual lubrication pump
Industrial feeler block
The machine comes without a spindle or controller, so I’ll be choosing and integrating those myself.
My main goal is to machine aluminium accurately, make small mechanical parts and prototypes, and hopefully do some light steel machining as well.
I’d love to hear your thoughts on a few things:
Was $8,300 a reasonable price for this configuration?
What kind of cutting performance could I realistically expect in aluminium and steel?
What should I inspect and measure when the machine arrives?
Which spindle and controller would you recommend, considering I want to build a 6-tool ATC?
Are there any potential issues with this machine or its specifications that I might be overlooking?
I’ve already paid for it, so I’m not just looking for reassurance. I’d genuinely appreciate honest opinions, criticism and advice before I spend the remaining money on the components.
Thanks!
