Match the holder and station
Use this checklist once for the transfer route, with a drawing for each station. The ITS 50 / ER-036345-style name identifies an application route; it does not establish interchangeability.
Holder and interface
- Match the exact holder or pallet, adaptive spigot, chuck model and revision, locating geometry and machine-side drawing before order release. Resolve the two catalogue spigot references in the specification table with the approved drawing.
- Check mounting pattern, adapter, orientation, stack height, load direction, centre of gravity, permitted load, environment and required options at every station.
- For WEDM-to-inspection transfer, the datum-transfer checklist covers holder-family checks and offset handling. For a System 3R-style machine-side route, compare the R-Series.
Body and access
Compare standard, lateral, right-angle and compact EDM bodies by holder-loading direction, footprint, tank rim, machine travels, work envelope, tool and hose clearance, and service access.
For NT-S100P80V1, use its own force, weight and 15 kg clamping-load row. That clamping-load value is not a general workpiece, robot-payload, dynamic-load or machining-load rating.
For unattended loading, continue to the signal matrix and complete-cell safety checks.

Process-specific checks
Define the pallet or carrier, transfer queue and process-state feedback needed by the loading sequence.
Use a short, rigid holder stack. Check vibration response, datum shift, tolerances, surface finish and process capability on the installed machine.
Check holder balance, dynamic load, rigidity, tool clearance and coolant-mist protection. Compare the measured changeover baseline with the proposed transfer route.
Map electrode preparation, EDM and inspection as one route. Record the master-holder ID in the quality plan and compare total lead time with the current process.
Ports and sequence signals
The release port opens the clamp for loading and unloading. Use the selected valve / PLC sequence and air-supply checklist.
Where equipped, a timed valve / PLC pulse supplies one cleaning step. The cleaning and seating procedure defines the rest of the cycle.
A pressure switch or proximity sensor can feed an M-code / PLC input with the chuck's clamp state.
A machine I/O or interlock input reports holder presence or seating from the configured sensing method.
A PLC or MES cycle count supplies service-planning data for seals and springs; inspection triggers belong in the service plan.
The complete-cell safety plan defines how these process signals relate to guarding, stop and recovery functions.

Installation, air and maintenance
Choose the body and mating components with the holder-and-station checklist before installation.
Installation and operating circuit
Mounting
Use the approved adapter, bolt pattern, dowels, torque, flatness method and machine-table drawing. Do not re-machine the plate without engineering approval.
Air supply
Operating pressure for the four listed models is 0.5–0.8 MPa at the chuck. Confirm the selected circuit, then specify air quality, filtration, drying, drainage, hose and valve sizing, and dielectric protection from the model manual and measured site conditions. No generic filter grade or line length applies to every installation.
Dielectric and seal compatibility
Check elastomer, seal-kit and port protection against the actual EDM oil or deionized water, environment and order scope. Family naming alone does not establish media compatibility.
Cleaning and seating
For models with air blast, define the timed pulse, wipe, purge and visual-inspection steps for the actual graphite, dielectric and chip load and sealing arrangement. Verify seating independently before machining; air blast alone does not prove a clean interface or datum return.
Service plan and fault diagnosis
Set inspection and cleaning triggers from the selected model manual, cycle count, environment, measured wear, leakage and actuation response. Inspect seals, springs, holders, spigots and ports; define the required spares during configuration review.
Check
EDM sludge or other contamination, mounting, holder/spigot condition, load, circuit or measurement changes.
Action
Stop and inspect the stack. Compare the cleaning, mounting, load, circuit and measurement logs with the agreed control plan.
Check
Thermal growth in the tank, part or electrode.
Action
Use measured tank and part temperatures to define stabilization and datum re-verification.
Check
Contamination, damage or mismatched holder/spigot geometry, mounting error or incomplete release.
Action
Stop the cycle. Correct the interface or release fault and verify seating before reuse.
Check
Graphite dust in ports, pressure at the chuck, leakage, restriction, valve/hose sizing or a circuit fault.
Action
Restore the specified air-supply conditions, inspect filtration and drainage, and locate the restriction or leak before returning to service.
Check
Dielectric attack, seal damage, unsuitable shielding, port protection or routing.
Action
Correct the media or environment protection and replace degraded seals to the service plan; record leakage and response before reuse.

Acceptance & commissioning checks
Acceptance and commissioning
Complete-cell control and safety
Springs clamp the holder and air releases it. Mechanical self-locking or air-loss holding is a workholding mechanism, not a machine or robot-cell safety function. Ordinary clamp, pressure, proximity and seating signals report process state; they are not automatically safety-rated.
- The integrator's complete-cell risk assessment defines guarding, interlocks, safety-related controls and their required performance and diagnostic coverage.
- Check the model-specific air-loss response on the drawing. Define fault detection, stop, safe state, reset and recovery for the complete machine and handling sequence, then validate those functions through FAT/SAT or equivalent acceptance.
- If robot or handler motion is not safely inhibited, stop commissioning until that control and safety chain has been validated.
Record the acceptance evidence
Qualify a traceable master holder or gauge at each station. Use a CMM, indicator or agreed method to cycle, load and measure the installed stack; set the sample size, sequence, cycles, load, temperature and measurement uncertainty in the FAT/SAT plan. Record the installed Z datum and cross-station results against the agreed process criterion. The catalogue repeatability in the model table is the component comparison point.
Test the assembly selected with the interface checklist. Record surface condition, independent seating evidence, load and datum return; verify that geometry, orientation and stack height meet the approved drawing. For air-blast models, test the documented cleaning cycle.
Measure pressure at the chuck and clamp/release timing across its specified range and the agreed load, temperature and fault cases. Record the model's air-loss response. Use the agreed leak-test pressure, medium, hold time and decay/leakage threshold, and confirm that timing and leakage meet the project limits.
Retain the verification report, traceable QC results, master-holder identification, maintenance notes and service plan. The complete-cell control and safety evidence above is part of the FAT/SAT handover.

Frequently Asked Questions
What repeat positioning accuracy is listed for the E-Series Model 100 variants?
The four named Model 100 variants list <0.003 mm component repeat positioning. See the model comparison and installed-datum test.
How does the clamping mechanism work, and what force is listed?
Mechanical self-locking clamps the holder; air releases it. The model table separates each model’s clamping force and clamping-load data.
Is it intended for ITS 50 / ER-036345-style holders and pallets?
Yes, as a model-specific interface route. Use the holder-and-station checklist to confirm the mating components.
Which processes is it best suited for?
Electrode preparation, sinker EDM, WEDM transfer, grinding and inspection are the main application routes. The process-specific checks distinguish their setup needs.
How does it handle chips, dielectric fluid, and debris in automation?
Where equipped, air blast is one cleaning step. Follow the cleaning and seating procedure for the rest of the cycle.
What air supply quality is recommended for stable unattended cycles?
Use the air-supply checklist for the listed operating range and site-specific preparation.
How do I maintain the same Z reference across multiple machines?
Measure each station against a traceable master. The datum-acceptance procedure defines the measurements and records.
Can it be integrated with robots or pallet systems safely?
Robot loading requires complete-cell integration and acceptance. Use the control and safety checks to define that scope.
