Zero-point clamping system video
See the zero-point locking sequence in action
Choose this page when the real question is the locking interface itself. The MFG module family covers compact receivers, multi-station blocks, and control-ready options for shops that need stable repeatability plus a cleaner path into pallet transfer, APC, or robot-assisted workholding.
Use this page when you are buying loose receiver modules — single units or 2/4/6-station MFG combination blocks — to drop into a custom subplate, tombstone, or OEM fixture. If you want a finished, drilled, ready-to-bolt plate instead, see the Quick-Change Zero-Point Clamping Plate or the air-actuated Pneumatic Zero-Point Plate.
Best fit
Use this route when the buyer is selecting pull studs, receiver spacing, air routing, and control feedback rather than just looking for a datum plate under an existing fixture.
Integration prep
Provide pallet size, pull-stud standard, inlet preference, sensor or confirmation requirements, and whether the module will tie into APC, robot, or manual quick-change stations.
We configure the right zero-point module layout, pull-down force class, and air routing to match your pallet logistics and changeover targets.
Fast RFQ paths
Need drawings or a quick reply? Send the buying context directly.
The form will prefill Zero-Point Clamping System so the inquiry reaches the right product context.
Provide the machine model, table dimensions, and whether you need a single, dual, or quad receiver pattern. Include the mounting bolt circle if converting from another zero-point brand.
Share the pallet or sub-plate size, total fixture weight, required pull-down force per stud, and whether pallets transfer between machines, CMM, or storage.
Specify your air supply pressure, whether lock-state confirmation sensors are needed, the planned automation tier (manual, robot-loaded, or FMS), and changeover time targets.
Best fit
Best for projects centered on pull studs, receiver spacing, air routing, and lock-state confirmation across pallets, vises, or automation carriers.
Compare first
Single receiver modules, combination blocks, and control-ready versions become easier to compare once those three constraints are locked.

Nextas Tech Zero-Point modules are built from high-grade, hardened alloy steel for rigidity and long service life. The locking mechanism uses pneumatic pressure (typically 6 bar) to overcome powerful springs for unlocking. When the air is removed, these springs pull in and lock the clamping stud, creating a secure, vibration-proof connection that maintains its force even if air pressure is lost.
This demonstration shows how the Zero-Point Clamping System enables fast pallet changes. The locking mechanism holds precision positioning within <0.003mm and allows complete changeovers in seconds.

Choose bottom-inlet routing when you can bring air through the table or subplate and want the cleanest, best-protected layout. Choose side-inlet routing when retrofit access, hose serviceability, or machine constraints make lateral connection the more practical solution.

Zero-point systems pay off fastest when you standardize one interface across multiple setups. Here are the most common upgrade routes we support.
Mount a receiver pattern on a sub-plate and add pull studs to your vises/fixtures. Great for mixed-batch work and short runs.
Use dense receiver layouts and low-profile fixtures to maximize tool access and reduce re-indicating between operations.
Add clamp confirmation signals and consistent pallets to enable safe unattended changeovers and higher spindle uptime.
These guidelines help early-stage planning for a quick-change pallet / fixture interface. Final selection depends on cutting loads, moments, and machine constraints — share your setup and we’ll propose a layout.
For zero-point workholding, repeatability isn’t just a spec — it’s the result of material control, precision grinding, and functional testing. Nextas Tech focuses on stable long-term performance in real chip-and-coolant environments.
Build fixtures and mount workpieces on pallets while the machine is running, sharply increasing machine uptime.
Use the same setup across multiple machines (3-axis, 5-axis, CMMs) for ultimate flexibility and reduced fixture inventory.
Built-in sensing and pneumatic control provide the feedback needed for robotic pallet changers and unmanned cells.
The compact modules allow for creative fixturing with minimal interference, providing maximum tool access.
Most changeover problems get solved earlier when receiver layout, inlet routing and pallet strategy are matched to the machine and part family before the fixture design is frozen.
Ideal for compact fixtures, 5-axis work, vises or pallets that need a low-profile interface and direct maintenance access.
A stronger starting point when a fixture needs multiple clamping points, higher support rigidity, or a denser palletized layout.
Choose bottom inlet when under-table routing is available and protection is the priority. Choose side inlet when retrofit access or utility routing makes the lateral connection more practical.
Machine table, available mounting area, stack-height limit and whether the fixture is 3-axis, 4-axis or 5-axis.
Fixture mass, part family, roughing severity and whether the fixture has to move between machining and inspection.
Tell us whether air can come through the table, through a sub-plate, or only from the side so inlet selection stays practical.
Share changeover targets, pallet count, robot transfer requirements and the clamp / unclamp confirmation signals you need.
Zero-point clamping systems use precision receiver modules—single, dual, or quad patterns—to lock fixtures, pallets, and tombstones with sub-0.005 mm repeatability. This cheatsheet covers module pattern selection, pneumatic/hydraulic integration, and long-term maintenance for automated and manual cells.

Contact usUse this checklist to validate repeatability, pull-down force, and automation fit during supplier evaluation.
Tip: include your pallet dimensions, pull-stud standard, and automation level. We’ll map the receiver pattern and confirm pull-down force.
Our zero-point system uses powerful pre-loaded springs as the primary locking mechanism. Clamping is mechanical and constant. Pneumatic pressure (typically 6 bar) is used to enable. If air pressure is lost, your workpiece remains secured — ideal for unattended machining and automation.
Bottom inlet routes air through the machine table or sub-plate for a clean, protected installation. Side inlet is a flexible option when through-table routing isn’t possible — air lines connect from the side of the module.
Yes. We commonly see zero-point receivers used on CMM inspection stations, welding fixtures, assembly lines, and EDM processes — anywhere that repeatable positioning and fast changeover improve throughput.
Keep the seating area clean, inspect periodically, and apply light lubrication as specified in the manual. In chip- and coolant-heavy environments, routine wipe-down and occasional leak checks help keep unlocking and seating consistent over time.
Automation-ready modules can be configured with sensor ports for proximity sensors that provide clamp/unclamp confirmation. This feedback can be wired to a PLC or robot controller to validate system status before an automated cycle starts.
Start with pallet/fixture footprint, part and fixture weight, and cutting loads. Smaller receivers fit compact 5-axis fixtures and dense layouts; larger diameters provide higher load capacity and stiffness for heavier pallets, tombstones, and roughing. Share your table size and changeover goal and we can recommend a safe configuration.
The pull stud is the precision interface between your fixture and the receiver, so it impacts repeatability and wear. Choose the style based on clearance, fixture thickness, and whether you need anti-rotation. Precision-ground studs with consistent hardness and surface finish help keep repeatability stable over many cycles.
Use clean, dry air at the specified unlocking pressure (typically 6 bar). A filter-regulator or FRL unit helps protect seals and keeps unlocking consistent. Stable air quality is especially important for automated cells and repeatable unclamp timing.
Yes. Many customers retrofit vises, chucks, and custom fixtures by adding pull studs to an adapter plate or the fixture base. The key is maintaining a stable datum scheme (flatness and bolt pattern) and providing chip/coolant clearance so the system seats cleanly every time. Send us your fixture drawing and we’ll propose a practical retrofit approach.
Standard MFG receiver modules and 2/4/6-station combination blocks ship in roughly 15–25 days after PO confirmation. Custom receiver spacing, sensor options, or OEM-branded configurations add about a week. Committed lead time is confirmed in writing once module count and pull-stud spec are locked.
Each MFG receiver module ships with a factory inspection report covering pull-stud repeatability, locking force, and seating geometry against the listed specification. Material certificates for the hardened body, calibration traceability, and the written warranty are available on request at order time.
The ideal foundation. Our plates come with modules pre-installed for easy setup on any machine.
