Use the R-Series when the project needs one reference family across multiple stations instead of isolated single-purpose fixtures. The range covers powerful pneumatic, standard pneumatic, side-vertical, right-angle, manual, and extension variants, so selection starts with workflow and air-routing logic rather than a single model code.
Where the E-Series is a tight ITS-based toolkit for the electrode-prep and EDM chain, the R-Series is the broader System 3R–compatible family covering CNC milling, turning subplates, presetting, and CMM transfer. Pick the R-Series when one datum logic must span more than just the EDM loop.
Best fit
A strong route for shops that want the same reference logic shared between CNC, EDM, presetting, inspection, and later automation upgrades.
Selection prep
The fastest qualification usually comes from deciding pneumatic vs manual, top vs side air access, and whether right-angle or extension geometry is needed.
The fastest way to qualify an R-Series project is to decide whether the station needs pneumatic loading, manual transfer, or a special air-routing geometry.
You want repeatable machine-side loading, faster changeovers, and a datum chuck that can support future automation or standardized transfer.
Air is unavailable, presetting is offline, or the workflow needs simple manual transfer with the same reference logic across stations.
Air routing, machine enclosure clearance, or fixture geometry makes a standard top-fed pneumatic layout hard to service or protect.
Tell us whether the same chuck logic must move between CNC, EDM, presetting, inspection, or only one machine.
Share available air, table pattern, clearance limits, and whether you need standard, right-angle, side-vertical, or manual access.
Include workpiece, electrode, holder, or fixture size together with your current spigot or pallet standard.
Let us know whether the main goal is faster setup, tighter repeatability, easier transfer, or preparation for unattended running.
One datum family, multiple chuck formats, and cleaner transfer between machines and stations.
The R-Series is not just one chuck body. It is a datum chuck family that covers high-force pneumatic clamping, compact side vertical installation, right-angle accessibility, manual quick-change, and manual extension formats. That gives engineers a cleaner way to standardize one positioning logic while still matching different table layouts, rotary setups, offline presetting benches, and changeover routines.
For shops that want one reference language across CNC milling, EDM, and inspection, this matters more than a single product headline. You can use the same family logic while choosing the chuck body that best fits the process, the reach requirement, and whether air is available at the station.
The pneumatic variants are presented in the catalogue with mechanical self-locking, positioning datum self-cleaning, positioning airtightness testing, and inner-hole cleaning functions. Those features are meant to support repeatable seating and reliable operation in real production environments, especially when chucks are repeatedly loaded, unloaded, and cleaned around coolant and chips.
The manual chuck remains valuable when you need the same reference idea without pneumatic plumbing. It is suited to manual quick-change operations, and the extension versions help when more reach is needed around fixtures, towers, or machine obstructions.
R-SERIES VARIANTS
Pick the chuck body that fits your spindle layout and access angle — every variant shares the same R-series interface so accessories and pull studs interchange.
Below is the core R-Series datum chuck range shown in the catalogue, including the corrected standard pneumatic and right-angle model assignments, plus the matching spigots and manual extension options used to complete the system.

Pneumatic models are listed in the catalogue with 0.5–0.8 MPa pressure actuation, mechanical self-locking, positioning-datum self-cleaning, air-tightness testing, and inner-hole cleaning related functions. Confirm the final mounting stack, air routing, and spigot family before standardizing across multiple machines.
Choose the chuck body by machine layout, changeover style, and whether the station uses air or manual quick change.
Start with the workflow, not the name. If the process involves higher cutting forces, more automated actuation, or frequent loading cycles, the pneumatic family is the natural starting point. If you need fast manual setup where air lines are unavailable, the manual chuck or one of the manual extension versions is the better fit.
Keep the chuck, spigot, pallet, and mounting plate as one defined datum stack. In practice, the most common repeatability losses come from mismatched interfaces, dirty reference faces, or a mounting base that is less rigid than the chuck itself.
Plan clean 0.5–0.8 MPa air, rigid mounting, and access for cleaning. Use pneumatic variants when you want faster machine-side actuation, consistent changeover behavior, and better fit for production-focused stations.
Use the manual chuck as a no-air quick-change base for presetting, fixture preparation, manual milling setups, or inspection transfer. Add the extension models when access or stack height is a real constraint.
Use these controls when you standardize the R-Series family across multiple machines, setup benches, or inspection stations.
| Factor | What you’ll notice | Best practice | Why it matters |
|---|---|---|---|
| Dirty locating faces or bores | Z shift, tilt, or incomplete seating | Wipe, air-blow, and protect the interface during storage | Contamination is the fastest way to lose repeatability |
| Mismatched or worn spigots | Unstable interchange or rough seating feel | Standardize spigot selection and inspect wear routinely | The chuck is only as stable as the matched interface |
| Weak mounting base | Movement under load or inconsistent results machine-to-machine | Use a rigid sub-plate or defined fixture plate stack | Base rigidity protects the datum performance |
| Contaminated air on pneumatic models | Slow actuation, leaks, sticky motion | Filter and dry the air supply; inspect lines and seals | Keeps production cycling predictable |
| Poor manual handling discipline | Dings, burrs, storage damage, hard-to-trace drift | Use trays, covers, and a standard cleaning routine | Protects the reference geometry over time |
Tip: write the chuck model, spigot model, mounting plate, and station name into the work instruction so operators always rebuild the same stack.
The R-Series family supports different layouts, not just different industries.
Keep one datum logic between milling, sinker EDM, and measurement stations.
Use pneumatic or manual variants to reduce rebuild time on short-run work.
Side vertical and right-angle formats help when fixture access and indexing orientation matter.
Manual and extension variants help build, transfer, and verify setups away from the spindle.
A shop standardizes one reference family across milling, sinker EDM, and inspection. Pneumatic chucks stay on production stations while a manual chuck is used at the setup bench to prepare and verify holders before transfer.
The side vertical and right-angle variants are selected to keep the datum logic consistent while improving access around rotary fixtures, tombstones, or multi-face machining layouts.
Operators build and check workholding offline with the manual chuck or extension version, then transfer the prepared setup to the machine-side datum base with less spindle downtime and fewer rebuild errors.
Use this rollout plan when you want the R-Series family to act like one coherent datum system across production, presetting, and inspection.
Pick the variant that matches the machine layout and the way operators actually change over work.
| Workflow | Primary goal | Recommended model | Why it fits |
|---|---|---|---|
| Heavy or rigid pneumatic cutting setup | Higher clamp force | NT-S100P150RV1 | Powerful pneumatic model with >10,000 N clamp force |
| Compact 4-side machine layout | Orientation flexibility | NT-S100P100RV2 | Side vertical format supports four-side interchange |
| 5-face accessibility / rotary integration | Access around multi-axis fixtures | NT-S100P100RV3 | Right-angle body helps fit more complex fixture geometry |
| General pneumatic datum base | Repeatable machine-side quick change | NT-S100P100RV1 | Standard pneumatic family choice for regular production cells |
| No-air presetting or manual work | Flexible offline setup | NT-S100P56RV1 | Manual quick-change chuck for stations without pneumatic lines |
| Extra reach around fixtures | Clearance / stack height | NT-S100P56RV2 / RV3 | Manual extension options add 6 in or 10 in reach |
Check the whole datum stack, not just the chuck body.
| Test | What to record | Tools | Pass criteria |
|---|---|---|---|
| Re-clamp repeat check | Indicator reading after multiple re-seats | Dial indicator + reference pallet / pin | Stable against your internal process tolerance |
| Interface cleanliness check | Visual and tactile seating condition | Air gun, wipes, inspection light | No rocking, no visible contamination, smooth seating |
| Air performance check (pneumatic) | Pressure stability and cycle behavior | Pressure gauge / regulator check | Reliable actuation in the 0.5–0.8 MPa range |
| Transfer verification | Result after moving between machine / bench / inspection | Indicator or process-specific measurement | No unexpected datum shift after controlled handling |
Simple routines that protect interchangeability and seating quality.
| Interval | Action | Why it matters | Consumables / tools |
|---|---|---|---|
| Each shift | Clean locating faces, bores, and spigots | Prevents contamination-driven drift | Lint-free wipes, filtered air, light oil |
| Weekly | Check for burrs, dings, and seating wear | Protects long-term reference quality | Inspection light, deburr stone if needed |
| Monthly | Verify baseline repeatability on a reference stack | Confirms the system still behaves as expected | Indicator, reference pallet / pin |
| Quarterly | Inspect air routing, seals, and mounting fasteners | Important for pneumatic reliability and base stability | Pressure check tools, torque tools |
Common symptoms and quick fixes for a datum chuck family used across multiple stations.
| Symptom | Likely cause | Quick fix | Prevention |
|---|---|---|---|
| Repeatability suddenly worsens | Dirty locating faces or wrong spigot | Clean, confirm interface match, and re-seat | Label the stack and clean at every changeover |
| Pneumatic cycle feels slow or unstable | Air contamination or pressure variation | Check regulator, filters, and air lines | Use clean, dry air and schedule inspections |
| Manual setup feels awkward to access | Insufficient reach around the fixture | Review the manual extension options | Select the extension length during setup planning |
| Interchange varies station-to-station | Different mounting bases or operator practice | Standardize the mounting stack and acceptance check | Use one documented datum build for every station |

The family on this page covers powerful pneumatic, side vertical pneumatic, right-angle pneumatic, standard pneumatic, manual, and manual extension chuck formats, plus the matching spigots used to complete each interface.
NT-S100P150RV1, NT-S100P100RV2, NT-S100P100RV1, and NT-S100P100RV3 are pneumatic chuck formats. NT-S100P56RV1 is the manual chuck, while NT-S100P56RV2 and NT-S100P56RV3 are manual extension chuck options.
The pneumatic catalogue models are specified at less than 0.003 mm repeat positioning accuracy. In production, the real result still depends on the matched spigot, the mounting base, the cleanliness of the locating surfaces, and the way the stack is maintained.
Choose the side vertical chuck when compact four-side interchange or side-oriented installation is the main goal. Choose the right-angle chuck when fixture access, multi-axis orientation, or five-face accessibility matters more.
Yes. The manual chuck is intended for quick-change work in environments where air tubing is not available, which makes it useful for presetting, fixture preparation, inspection transfer, and flexible machine-side setups.
The pneumatic catalogue models use pressure actuation in the 0.5–0.8 MPa range. In real use, you should also plan for clean air, a rigid mounting base, and a simple routine for cleaning the locating surfaces and inner interfaces.
Yes, the page is positioned around System 3R-compatible referencing workflows. Before scaling across multiple stations, confirm the pallet, spigot, and mounting pattern you plan to standardize so interchangeability stays controlled.
Yes. We can help you match the chuck body, spigot type, extension length, mounting plate, and installation style to your machine table, fixture plate, presetting bench, or inspection workflow.
Standard R-Series chucks — pneumatic, manual, side-vertical, and right-angle variants — ship 4–6 weeks after PO confirmation. Custom pull-stud configurations, extension formats, or matched datum sets across machines add 1–2 weeks. Committed lead time is confirmed in writing once the variant mix and pull-stud standard are locked.
Each chuck ships with a factory inspection report covering pull-stud receiver repeatability (<0.003 mm), seating flatness, and pneumatic unlock pressure. Material certificates for the hardened body, System 3R compatibility verification, and the written warranty are available on request at order time.
