QVM-610AII VMC Pallet Exchange: Four Seconds at the Stated Test Load

The product data gives a 700 × 410 mm table and maximum load of 400 kg × 2.

Technical application analysis. Fixture-mounted workpieces; QVM-610AII vertical machining center; electric roller-cam APC.

Reference configuration and timing

The product data gives a 700 × 410 mm table and maximum load of 400 kg × 2.
Its 4 s table exchange is stated at a 200 kg test load.
The APC uses a roller-cam mechanism with an electric motor, not the hydraulic mechanism inferred in the original spreadsheet.

Engineering evaluation

Maximum permissible load and the load used for a speed test are separate selection inputs. Do not combine 400 kg and 4 s into an unsupported full-load exchange claim.

Decide how the external station will be loaded: manual fixturing or robotic handling. Either approach needs an accessible fixture interface and a defined exchange permission; an APC does not add loose-part recognition by itself.

Selection conditions and evidence limits

This is a manufacturer-product analysis without a customer, material or output claim. Confirm the ordered configuration and the stated timing test conditions.

Application questions

Is the four-second exchange proven at maximum load?

The cited condition is 200 kg; the maximum-load figure cannot be substituted for it.

Does this APC use hydraulic drive?

The cited description specifies electric motor and roller-cam drive; external fixture hydraulics would be a separate issue.
