Selection & Integration Guide
Choose the right zero-point architecture first
Choose a single module or a multi-station layout around the fixture geometry and exchange route.
Single receiver modules
Use a single receiver on a compact fixture, a 5-axis setup, a vise, or a pallet that needs a low profile and access for service.
Combination blocks
A stronger starting point when a fixture needs multiple clamping points, higher support rigidity, or a denser palletized layout.
Bottom inlet vs side inlet
Bottom inlet keeps the air connection within the mounting stack; side inlet uses an external connection. Compare routing and service access.
How to specify a zero-point system for your machine
- Choose the layout: define whether pallets, fixtures or both will change, then choose an architecture above.
- Select receiver size: based on fixture weight, cutting load, and available footprint (85 / 125 / 160 / 195 mm options).
- Match the studs: choose the required roles and quantities from the assembly drawing, then confirm each matched part in the pull-stud pairing table.
- Plan the sub-plate: optimize receiver spacing for tool access, chip flow, and coolant drainage.
- Decide air routing: use the inlet comparison to choose the connection route before machining the sub-plate.
- Validate the installed layout: agree the assembly, measurement and control acceptance tests before the trial.

A complete setup. A clear investment.
Plan receivers, matching pull studs and fixture-base requirements together with NEXTAS. Share your machine, pallet count and changeover frequency so our engineers can recommend a practical layout and quote the required package. Use that proposal to compare the setup investment with the machine time you aim to recover.
Typical retrofit paths
Standardize one interface across setups. These are the usual retrofit routes.
3-axis CNC → quick-change fixtures
Mount a receiver pattern on a sub-plate and add pull studs to the vises and fixtures. That covers mixed batches and short runs.
5-axis CNC → compact, high-access fixturing
Use dense receiver layouts and low-profile fixtures to maximize tool access and reduce re-indicating between operations.
Automation cell → pallet pool / APC / robot
Add clamp-state signals and the same pallet so a robot or an APC can exchange it.
Receiver sizing & layout quick guide
Compare the fixture’s total mass, cutting loads and moments. Determine receiver count by layout analysis unless a count is listed below; receiver size alone does not establish installed rigidity.
Recommended receiver
85 mm
Notes
- Prioritize low height and tool access.
- Use anti-rotation features when needed.
- Keep chip evacuation paths open.
Recommended receiver
125 mm
Typical receiver count
4
Notes
- A 4-point pattern is a common standard for repeatable pallet swaps.
- Balance spacing with bolt access and coolant drainage.
- Fits mixed-batch work on a 3-axis machine.
Recommended receiver
160 mm
Notes
- Use more receivers to improve rigidity against high moments.
- Increase receiver spacing to reduce plate bending.
- Plan air manifolds and service access up front.
Recommended receiver
195 mm
Notes
- Favor stiffness and stable pull-down for unattended machining.
- Define required feedback in the control acceptance plan.
- Standardize pallets to build a reliable pool.
Bottom inlet vs. side inlet routing
Best when
You can route air through the table/sub-plate for a clean, protected setup.
Plumbing notes
- The line stays inside the plate, so chips do not sit on the hose.
- Plan ports before machining the plate.
- Use FRL / filtration close to the supply.
Automation notes
- Easier manifold routing for multi-receiver plates and pallet pools.
- Cleaner hose management for robot/APC cells.
- Consistent pressure drop across pallets.
Best when
Through-table routing isn’t possible, or you need a fast retrofit on existing plates.
Plumbing notes
- Keep hoses protected from chips and toolpaths.
- Use strain relief and guards.
- Label lines to reduce setup mistakes.
Automation notes
- A side inlet still works on a robot or APC. Keep the unlock time consistent.
- Add confirmation signals (sensor or pressure switch) where required.
- Keep quick-disconnects accessible for maintenance.

Installation and maintenance checks
Follow the selected model’s installation and service instructions. Use the checks below during commissioning and routine care.
For architecture and receiver sizing, use the layout selection above. For port position and hose protection, use the bottom/side inlet comparison.
Integration: what to prepare before install
Typical choice
CNC the pocket pattern into the base plate per the module drawing; use dowel pins for angular lock.
Practical tip
Machine the pockets in one setup so all modules share the same Z reference plane.
Typical choice
Take supply pressure, filtration, air quality, valves, and the sensing circuit from the selected drawing.
Practical tip
Never tee pneumatic modules off a machine’s spindle-blow line. Pressure spikes cause false releases.
Typical choice
Wire proximity or pressure sensors per module to PLC; gate spindle start and robot motion.
Practical tip
Test each module’s feedback individually in the control acceptance checks.
Typical choice
Connect a low-pressure test line to verify the pull-stud is fully seated before machining.
Practical tip
Include an incomplete seat and a seating-check timeout in the acceptance tests.
Maintenance: keep repeatability stable
Follow the selected model’s manual for light lubrication and periodic leak checks, particularly in chip- and coolant-heavy service.
Early symptom
Pull-stud won’t seat; clamp force drops; air-test fails.
Prevention / quick fix
Blow out each bore before loading; add protective caps when modules sit idle overnight.
Early symptom
Repeatability scatter increases; holding force declines over time.
Prevention / quick fix
Track cycle count per module; inspect internal mechanism at the interval in the service manual.
Early symptom
Surface pitting on the module face; sticking during unlock.
Prevention / quick fix
Drain coolant pools after every shift; apply a thin rust-inhibitor film on exposed faces.
Early symptom
Audible air leak during hold; module unlocks sluggishly.
Prevention / quick fix
Replace seals at the recommended cycle count; keep a rebuild kit per machine to avoid downtime.

Product Data & Evaluation Checklist
Agree the baseline process, test load, repeat sequence, measurement method and acceptance criteria before the trial. Use Technical Specifications for the catalogue values.
Assembly and load case
- Freeze the reviewed layout as an assembly drawing and BOM: receiver quantity, stud roles, mounting hardware, porting, datum faces, pull-down direction and anti-rotation features.
- Test the plate/pallet → receiver → fixture/vise/chuck → part stack for cutting loads, moments, pull-down force, base stiffness, contact and interface lift.
- Qualify mounting, clearance, load and datum at every machine and adapter in a transfer route.
Acceptance measurements
- Setup time: record pallet exchange, seating checks and re-indicating for the existing and proposed workflows.
- Datum return: measure position variation over the agreed re-clamping sequence, including any probing or offset correction.
- Part quality: compare equivalent multi-operation inspection results and investigate locating or tilt-related deviations.
Control validation and evidence
For APC or robot cells, verify each required clamp and seating signal, incomplete-seat and timeout responses, spindle/robot motion inhibition, guarding, interlocks, fault handling and recovery as a complete cell. Mechanical spring holding and ordinary process-state feedback are not safety functions.
- Retain the fixture layout drawing with receiver spacing and datum scheme, and photos or video of the clamp/unclamp and pallet-exchange sequence.
- Record the re-clamping or probing inspection results; an inspection excerpt can support incoming review.
- Confirm the engineering next steps from the available part and machine information, spare studs/seals/receiver components and maintenance checklist. Optional FAT video is available for key assemblies.

Frequently Asked Questions
How does mechanical locking work, and what must be validated?
Springs hold the seated stud; pneumatic models use air to release it. See Mechanism Details for air-loss behavior and the acceptance plan for complete-cell validation.
What is the difference between the 'Bottom Inlet' and 'Side Inlet' solutions?
Bottom inlet keeps plumbing inside the mounting stack; side inlet connects from the module flank when through-table routing is blocked. Use the plumbing and automation notes in Bottom inlet vs. side inlet routing before machining ports.
What is a zero point system on a CNC?
On a CNC, the receiver stays on the machine, subplate, or tombstone. The fixture or pallet carries the pull stud, seats to the same location, and comes off for the next job. The same receivers can also sit on a CMM, welding fixture, assembly station, or EDM when that job needs the same location. Send the machine, pallet size, and pull-stud standard for a quote.
What maintenance is required for the zero-point modules?
Keep the seating area clean and follow the selected model’s service instructions. The maintenance checks cover chip ingress, wear, coolant pooling and seal symptoms.
How do I integrate the system for automated position monitoring?
Confirm what each available sensor actually monitors and connect it to the PLC or robot controller. Use the installation checks for wiring and the acceptance plan for sequence and fault testing.
How do I select the receiver model and its mounting dimensions?
Compare fixture mass, cutting load and available footprint in the receiver selection guide. Use the selected drawing’s mounting dimensions and the D1/D2 distinctions in On the model drawing.
Which pull stud should I use, and how important is stud quality?
Choose the required stud roles and quantities from the assembly drawing and confirm each matching part in the pull-stud pairing table. Check clearance, fixture thickness and anti-rotation needs; ground finish and consistent hardness affect repeatability and wear.
What should I send for a zero-point receiver RFQ?
Start with the machine and fixture or pallet information you have. The optional receiver review details list the engineering inputs we can confirm together.
