Finished progect AR4 in Italy
Hi everyone, I've finished building two new machines and I'm excited to share the results with you. Both machines are designed to automate part replacement. The first one is a 4-axis CNC milling machine. We produce two types of identical products, and I've created two cassettes for them. /images/forum/media/2190477f29905ca3.avif A robot picks up a part from the cassette, places it on the machine, clamps it down, and starts the program. Once the program is finished, the machine's portal moves back, triggering a mechanical limit switch that signals the robot to start the next cycle. There's a limit switch in the cassette that stops the program if it's empty. One cycle takes 15 minutes (meaning the robot needs to work every 15 minutes). This machine has been running for 3 months and has completed over 1000 cycles. https://cqpppstrkbfubfnjwcuc.supabase.co/storage/v1/object/public/community-media/legacy/e74a2745-Finished-progect-AR4-in-Italy_video.mp4 The second one is more complex. It's a drilling machine. /images/forum/media/97463014c9887107.avif https://anninrobotics.vercel.app/media/oldsite-6d8645d1-984a-57f8-958b-259928a95cc7?f=.webp I've completely rebuilt an old machine with a rotary turret table. I added 8 pneumatic clamps and a rotary column. An Arduino Nano controller controls 10 relays: 8 for the pneumatic clamps, 1 for the vacuum suction cup, and 1 for pushing the next workpiece. This machine has only been running for a week. One cycle takes 40 seconds. In that week, we've done about 1500 cycles. So far, everything is working great. https://cqpppstrkbfubfnjwcuc.supabase.co/storage/v1/object/public/community-media/legacy/0ecbec9f-Finished-progect-AR4-in-Italy_4.mp4 In any case, I'll be able to provide feedback on how the robot performs over the long term, as it's currently running 8 hours a day.

Two AR4s finished, one working in a factory

I still not coplete the post about it, but it will be a little bit later. First of the robots is working full day in factory. It is chainging items for CNC milling machine. If you need some help or you want to see how it works i will be glad to help you
