JN-HD500 HMC: Thirteen-Second Pallet Exchange and External Fixturing

The data lists two 500 × 500 mm pallets and 500 kg maximum loading with uniform distribution.

Technical application analysis. Pallet-mounted workpieces; JN-HD500 horizontal machining center; dual 500 mm pallets.

Reference configuration and timing

The data lists two 500 × 500 mm pallets and 500 kg maximum loading with uniform distribution.
APC exchange is 13 s; 90° indexing is 2 s and is a different motion. Conflicting tool-change statements are excluded.

Engineering evaluation

The external pallet must be located and clamped before the exchange is permitted. Check fixture height, eccentric load and the rotating workpiece envelope together; pallet width alone is not a fit assessment.

Robotic part handling requires additional door, fixture-release and position signals. Model robot workpiece loading and machine pallet exchange as the actual sequence, identifying which steps can overlap.

Selection conditions and evidence limits

No actual housing customer or material is established by the source. The 13 s statement is confined to its documented product definition and configuration.

Application questions

Can the 2 s index replace the 13 s exchange in a cycle model?

No. Indexing angle and complete pallet exchange describe different tasks.

What does uniform load distribution mean for a large fixture?

The permitted load must be checked against the fixture and workpiece center of gravity, not only their combined mass.
