r/CNCmachining

Hello,

I'm looking for keep relay parameters for a Daewoo Puma 230M CNC lathe running a Fanuc 18i-TB control. I accidentally changed the parameters, causing the spindle to only rotate once, then stop and not continue with the program. I would be very grateful for your help.

I started a job today and obviously there’s shrapnel everywhere as you’re making the parts. Is it not common to wear facemask or respirator when you’re doing machining seems like it was all over my hands and possibly in the air.

I am currently working for a new start up location in TN while our support is in Pittsburgh. We are the 12th location for this company so we have been following tooling protocol form Pittsburgh themselves.
Recently we have been looking for a tool supplier/brands that are a little more local (current tools are an 8.5 hr drive from PA to us in TN). Therefore emergency packages overnight are expensive, time consuming if they even have them in stock..
Mitsubishi met all of our expectations and then some, however, their pricing is on the high side (we got 400 minutes and roughly 3,000 holes with a 9.3mm solid carbide drill).
Currently CGS is in our shop quoting for us. Our purchasing team from upper management is telling us that CGS tooling is the ‘Temu of tooling’ while everything I can find online looks to be reputable, dependable and materially efficient.
Has anyone used CGS tooling before? Should we stay away from them and bite the pricing bullet with Mitsubishi? Any other brands that you recommend (Solid Carbide preferred) would be helpful as well!

Applications: We drill, tap and mill flat plate for construction equipment. The material is typically A36 with some pickled options. Thickness is 30mm down to 12mm plates. Thanks in advance!

Hey guys,

I work in the CNC machining and custom parts sourcing space, and I’m currently looking to partner with CNC component manufacturers here in China.

I’ve been stuck on a few questions and would love to hear everyone’s real-world thoughts:

First off, is an in-person factory visit even necessary these days?
We can do video calls, check samples, review documents and photos online already. Is spending time and money to fly out and tour the factory really worth it?

Secondly, if I do go visit, what’s the typical process like?
And what are the key areas and details I absolutely need to inspect carefully while I’m there?

Also, are there any other hidden points or things most people overlook when vetting Chinese CNC factories in person?

Really appreciate any shared experience, tips, or honest opinions from anyone who’s done this before. Thanks a ton!
