Machine tending (CNC load / unload)

The cobot category's anchor application. Cell loads parts, machine cuts, cobot unloads. Operator-shift displacement is direct and measurable.

01 / OPERATIONAL SHAPE

What this application actually is.

Machine tending is the cobot category's volume application — load a part into a CNC mill or lathe, wait for the cycle, unload, repeat. It's where Universal Robots built its installed base and where Productive Robotics' OB7 became a category alternative. The operational shape is forgiving: parts are repeatable, the machine controls cycle timing, and the cobot has clear go / no-go states. Most cells are buffered so a brief cobot fault doesn't starve the machine. This forgiveness is why machine tending payback ranges are tight at the cohort low end (Interact Analysis cites 6 months on 24/7 best-case) and why first-cell buyers should start here.

02 / LEADING COBOTS FOR THIS APPLICATION

Which cobot fits, and why.

01Universal Robots UR5e
5 kg · 850 mm · $30,000-48,000
Volume reference for single-machine tending. URCap palletizing partners adapted for tending cells. 5 kg payload covers most CNC parts.
02Universal Robots UR10e
12.5 kg · 1300 mm · $45,000-60,000
Multi-machine tending where 5 kg isn't enough head-room for the tool changer. Larger parts (engine components, structural parts).
03Productive Robotics OB7
5 kg · 1000 mm · $24,900-27,000
Price-anchor alternative. Direct manufacturer support compresses parts cycle time. Right fit for cost-sensitive cells with simple part geometry.
04FANUC CRX-10iA
10 kg · 1249 mm · $40,000-52,000
8-year maintenance moat compounds on machine-tending applications where the cell runs continuously. Lifetime cost favours FANUC here.
03 / THE KILLER LINE ITEM

The cost most buyers underestimate.

Parts fixturing + presentation
$8,000-$35,000

Parts have to arrive at the cobot in repeatable orientation. Custom fixtures or vibratory feeders run $8-15K for simple geometry, $25-35K for complex. This is the most commonly underestimated line item — typical integrator quotes show '$12K integration' that doesn't separate this out.

04 / NO-PAYBACK FAILURE MODES

How machine tending (cnc load / unload)cells don't earn back.

!
Underestimating fixture cost
Integrators bundle fixturing into 'integration' line and buyers don't see it separately. Ask for a fixture-design quote before committing.
!
Single-machine ROI math on a multi-machine cell
If the application is one cobot servicing one CNC, the cobot is idle while the machine cuts. Payback works only if the cobot also tends a second machine, OR if the displaced operator was performing other tasks.
!
Variable part geometry without vision
Cells that try to handle multiple part types without vision usually fail within 6 months. Either commit to fixture-per-part-type or budget vision-guided pickup ($8-25K).
