Robot Wrist Flange Adapter 2024-T351 Aluminum ISO 9409 Tool Changer Pair 0.005mm Runout
ISO 9409 Flange Adapter
,Tool Changer Repeatability 0.005mm
,Robot and Tool Side Pairing
The Joint Between Robot and Tool
Every part you bolt to the wrist inherits whatever error the flange introduces. A plate that is flat but off-centre makes every tool sit eccentric. A plate with the right pattern but the wrong pilot diameter lets the tool shift under load, and the repeatability you paid for in the robot is gone at the interface.
This adapter is machined as an interface pair: one plate for the robot side, one for the tool side, both cut from the same stock, both referenced to the same datum, and both checked with the pilot, dowel holes and bolt pattern in one CMM run. Runout and pilot concentricity are measured on the assembly, not estimated from a single plate.
How the Pair Is Made
The pattern is only half the job. What follows is the sequence that makes a plate that stays flat after anodize and still locates on its dowels.
Precision Capability
| Characteristic | Held To | Verification |
|---|---|---|
| Pilot bore concentricity | 0.005 mm | CMM, pilot as datum |
| Face runout at bolt circle | 0.005 mm | CMM, full circle scan |
| Dowel hole position | 0.008 mm | CMM, best-fit pair |
| Dowel fit | H7 reamed and honed | Pin gauge, every hole |
| Face flatness | 0.005 mm | Granite plate, mapped check |
| Bolt hole position | 0.015 mm | CMM, pattern check |
| Pilot to register squareness | 0.008 mm | CMM, two axes |
| Mating face finish | Ra 0.4 µm | Roughness tester, per pair |

The Shop
Dongguan Changxinda Precision Technology Co., Ltd has machined custom parts since 2008. The floor runs 4-axis and 5-axis machining centres, turn-mill combination lathes, CNC lathes and milling machines, supported by an ISO 9001:2015 quality system and an in-house CMM room. Over 200 customers in medical equipment, robotics, automotive, aerospace, automation, laser, LED, lithium battery and precision instruments are supplied from this plant, and 50-60% of output is exported. Flange pattern work and pilot turning are everyday jobs here.

- Capacity around 10,000 pieces per month for this adapter family
- Repeat orders keep the same programme and masking plan, so fit stays the same after coating
- Each part number allocated across two machining centres to protect your date
- Express, air and sea freight; EXW, FOB or CIF terms; faces protected with film and rigid separators
- Rush capacity for line-down situations, quoted with a date we can hold
Key Features
- 2024-T351 plate for stiffness in a thin interface disc
- Robot-side and tool-side plates machined as a matched pair
- Pilot, register and mounting face turned in one clamping
- Pilot concentricity and face runout both held to 0.005 mm
- Dowel holes reamed and honed to H7, pin gauged individually
- Air, electrical and cable pass-through cut on 5-axis
- Anodize with fit surfaces masked so coating cannot change the fit
- NDA-protected handling and project-code documentation
Typical Applications
- Industrial robot end effector mounting
- Collaborative robot tool changer interfaces

FAQ
Q: Can you machine a pattern that is not standard ISO 9409?
A: Yes. Send the drawing, or the robot model and flange dimensions, and we will confirm the pattern before quoting. Brand-specific patterns are routine.
Q: Do I need both the robot side and the tool side?
A: Not always. Many customers order the tool side to fit an existing robot plate. When both are ordered we machine and verify them as a pair, which is the only way to guarantee the mated runout.
Q: Will you sign an NDA before we share the tooling drawing?
A: A mutual NDA is signed first, covering drawings, models, scans, samples and pass-through details.
Q: How is runout measured?
A: On the mated assembly: pilot as datum, full-circle CMM scan of the mounting face and bolt circle. The record ships with the pair.
Q: What is the minimum order?
A: One piece, with no tooling charge and no programming fee.
Q: Can you keep tool plates interchangeable across a fleet?
A: Yes. The programme, datum plan and masking are frozen, so tool plates from later batches seat on any robot plate from the same project.
Q: What do you need to quote?
A: Drawing or model, flange standard and size, pass-through requirements, quantity, coating and target date. Quote and interface notes return within 24 hours.
