Zero-Point System Selection Checklist
Fill this in per machine before choosing a zero-point interface. Most disappointing installations trace back to a question on this sheet that nobody asked early enough.
1 · The machine
Make, model and control
Table size and existing fixing pattern
Z travel and current clearance above the table
Every millimetre of stack height is Z travel you lose.
Vertical or horizontal spindle
Chip fall is different, and it changes seating-face protection.
Pallet changer or pallet pool fitted
Maximum table load, including fixture and part
2 · The work
Changeovers per shift on this machine
This is the number the whole business case rests on.
Current setup time per changeover
Typical part size and weight range
Heaviest cut expected
Determines required pull-in force and interface size.
Number of different fixtures to be interfaced
3 · Interface decisions
Base plate or direct mount into the table
Grid pitch chosen
Pick one pitch for the whole shop, not per machine.
Number of receivers per fixture
Two locate; additional ones add clamping force, not position.
Pneumatic or hydraulic release
Air supply route to the table decided
Seat-check (air seating) required
Effectively mandatory for unattended running.
4 · Chips, coolant and maintenance
How chips will be kept off seating faces
Covers, blow-off, or a cleaning step in the changeover routine.
Blow-off available at the interface
Cleaning routine agreed with operators
Written into the changeover sheet, not left to memory.
Spare seals and pull studs stocked
Verification procedure defined
A repeatable indicator check to confirm the interface still repeats.
5 · Rollout
First machine chosen
Start where changeovers are most frequent, not where it is easiest.
Fixture conversion order decided
Convert the highest-changeover fixtures first so savings arrive early.
Production protected during installation
Baseline setup times recorded
Without a before figure you cannot prove the after figure.
Operator training scheduled
Bring the completed sheet to your supplier discussion. If you would like it reviewed against your machine list, send it to us with the machine models.
