Two rail mounted cobots tend three CNCs in an optics shop

The job
WALT Machine Inc., a 25 person US shop, faces a seasonal crunch each spring: roughly 6,000 camera housings due in about two months. Rather than add machines and people, the shop hung a cobot from an overhead rail to load and unload its CNC around the clock, then added a second robot and expanded to three machines.
The shop
25 employees per the vendor case study; started with a single CNC machine on the automated job.
The equipment
Universal Robots UR10 mounted overhead on a rail to save floor space; Robotiq 2F-140 two finger gripper; Robotiq Wrist Camera for part location; Robotiq CNC machine tending kit.
The published numbers
Payload: not published. Rate: the first robot doubled daily production, published-by-vendor; batch capacity grew from about 2,000 to 2,500 parts to about 45,000 to 50,000 parts with two robots on three machines, which the vendor presents as a 2,500 percent increase, a vendor claim; 6,000 housings in 2 months, published-by-vendor. Cost: not published. Payback: not published.

What we would check before believing it applies to you
The overhead rail is the transferable idea: a small shop that cannot spare aisle space can still automate if the building structure allows ceiling mounting, so check overhead clearance and rigging early. The wrist camera earned its keep by finding parts without precision trays, which suits shops that cannot justify custom fixturing for every job. The headline percentage is a vendor framing of batch size growth, not a per hour speed claim, so verify actual spindle utilization gains on your own parts. Aluminum optics housings are light; heavier or oilier parts change gripper choice and may exceed what a camera pick can do reliably. Ask how the shop handles chip clearing and inspection between unattended cycles, because those tasks do not disappear.
