I know the 8L is fairly new to the market and there isn’t a ton of info or content out on it….yet.
I received my 8L this spring and have put it to work. I’ve cut acrylic, brass aluminum, titanium, copper, carbon steel, stainless steel, and even hardened O1 tool steel. With the right feeds and speeds along with proper tool and work holding it will hold very good tolerances and great surface finishes. I have also added gang tooling to my lathe and it’s been a game changer. I’ll post a few pictures of what my 8L has turned out and will do my best to help or answer any questions.
Great machine at an affordable price with awesome tech support.
Wow - thanks for sharing all those impressive photos @Chris_Zajic ! I’m glad you’re happy with your 8L.
Impressive parts and machine modifications @Chris_Zajic can you share any more details or pictures about how you interfaced your gang tooling block to the X-Axis carriage?
I have plans to do something similar, but there aren’t very many hard points in the stock carriage for adding hardware. Curious if you made some modifications to provide more mounting provisions.
I made a T-slot sub plate that bolts on to the carriage. I did drill and tap 2 more M6 holes into the carriage. I also still use the quick change tool post as well. Here are a few pictures.
@Chris_Zajic fantastic work! Wow.
Do you swap the gang tools in and out by the block or individual tools? Do the blocks have alignment features or do you have to sweep them in every time?
The bottom of the blocks are milled to have a ledge that sets against the sub plate. They are vary repeatable and I don’t even bother sweeping them in anymore.
As far as switching tooling I have a couple blocks set up for a specific part and only change tooling after wear or breaking . I have two more that I switched tooling out as needed. I haven’t had any issues with tool height changing much but it can be a little time consuming setting all your different offsets.
If I’m going to run more the 10 parts the gang tooling setup is definitely a time saver. I also plan on adding a automatic collet closer and bar puller in the near future.
Nice work! The sub-plate and tooling block setup looks great, and really improves the functionality. Thanks for sharing the details. I’ve been spoiled by a 12 position turret on our other lathe, so I think I’m going to follow your lead.
Very impressive. Is there enough X travel to reach all 4 gang tools and the part off? Will PathPilot auto tool change with the gang post without any modifications? I’ve been looking into this lathe and would need to do what you have done to make it make me money.
Chris, thanks for posting this. I see you are using a tailstock. Can you tell me where to adjust the settings so the tool does not crash into the tailstock? I am new so I don’t know what’s going on. Thanks
Yes, there is enough X travel to use all 5 tools including the parting/grooving tool. Here is a picture of my setup for a 3/4 dia. part. It is tight but there’s still plenty of clearance. When changed to gang tooling in Path Pilot it will switch tools automatically.
There is a set G30 on your main page above your X and Z reference buttons. I manually jog each tool and set G30 accordingly. I’ve only had to use the tail stock a few times and am very careful not to crash into it. I’m fairly new to CNC myself and hope this helps.
