R-Series Datum Chuck for CNC, EDM & Inspection Transfer
Match the datum chuck to each station
Choose a datum chuck around the way each station operates. R-Series includes pneumatic, manual, side-vertical, right-angle and extension formats for CNC, EDM, presetting and inspection. Match the chuck, spigot and mounting layout before comparing transfer performance across your intended stations.
Choose the actuation you needUse manual formats where air is unavailable, or compare pneumatic bodies for production stations with suitable utilities and controls.
Work around restricted accessReview side-vertical, right-angle and extension layouts against the loading direction, available reach and machine envelope.
Specify the complete interfaceSelect the mating spigot and mounting parts with the chuck. Pneumatic and manual formats have different listed spigot references.

Five-model quick fit
Which R-Series chuck fits your station?
Choose by three constraints first: available air, access direction, and the clamp-force class the process needs. Select the chuck, spigot, plate and machine mounting as one assembly.
1. Actuation
Pneumatic production station or manual no-air setup?
2. Geometry
Standard, side-vertical, right-angle, or extended reach?
3. Process load
General transfer or the higher-force pneumatic body?

Compatibility & integration
Lock the datum stack before ordering
Match the holder, spigot, adapter and rigid mounting base at every station. Check the actual interfaces against approved drawings before planning a transfer; the R-Series name alone does not establish interchangeability.
Compare the E-Series for an ITS-based electrode-preparation and EDM route. For R-Series CNC, EDM, presetting or CMM use, confirm the intended mounting and holder geometry rather than assuming either family is a direct substitute.
Interface match
The R-Series chuck, matching spigot, positioning plate, table pattern, and stack height are one assembly.
Utilities & access
For pneumatic models, plan clean 0.5–0.8 MPa air and serviceable routing. Check enclosure and rotary-axis clearance.
Acceptance method
Use the implementation and acceptance plan to define the measurements for your process tolerance.
Product Details
Review the mounting interface
Use the interface view to discuss the chuck, mating holder and mounting pattern. The five-model shortlist and full matrix distinguish actuation, force class and access direction.
Designed for repeatable transfer and practical maintenance
The pneumatic variants are presented in the catalog 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.
R-SERIES VARIANTS
Four R-Series chuck bodies on the same datum
Select the exact chuck and mating hardware by drawing. Pneumatic models list NT-S100P57RV1 spigots; the manual NT-S100P56RV1 and its extensions list NT-S100P36RV1. A shared R-Series name does not establish interchangeability.

Applications & station workflows
The product views show chuck formats; the workflow checks below define how to assess an intended station chain.
EDM & reference transfer
Keep one datum logic between milling, sinker EDM, and measurement stations.
High-mix CNC changeovers
Use pneumatic or manual variants to reduce rebuild time on short-run work.
4-axis / 5-axis layouts
Side vertical and right-angle formats help when fixture access and indexing orientation matter.
Presetting & inspection
Manual and extension variants help build, transfer, and verify setups away from the spindle.
EDM transfer
For milling, sinker EDM and inspection, define the holder, spigot and adapter pairing separately at each station. Pneumatic production chucks and a manual preparation bench require verified interface drawings before a transfer route can be specified.
Rotary-axis access
Review side-vertical and right-angle formats around rotary fixtures, tombstones or multi-face layouts. Check loading direction, tool reach, indexing orientation and the complete machine envelope.
Presetting & inspection
Manual and extension formats allow offline building and checking where air is unavailable. Record the matched holder, spigot and any adapter at the bench and destination, then measure the transfer rather than assuming direct interchange.
Catalogued installation views
The catalogue photographs show mounting layouts. Match the selected chuck, holder, machine envelope and process to the approved drawing.
Commission with evidence
Implementation & acceptance
Record each station’s verified datum assembly and validate it against the tolerance of your process. Include the assembled load and orientation, mounting stiffness, utilities and handling method in the acceptance record.
01 · Prepare
Match and clean the stack
Record the model, spigot, plate, fasteners, air routing, and clean reference surfaces.
02 · Verify
Re-clamp and transfer
Measure repeated seating and, where relevant, movement between machine, bench, and inspection.
03 · Release
Set the operating baseline
Approve against internal tolerance, then document cleaning, inspection, and escalation rules.
Acceptance test plan 4 checks
Re-clamp repeat: record indicator readings after multiple controlled re-seats.
Interface seating: confirm no contamination, rocking, burrs, or incomplete contact.
Pneumatic operation: verify stable cycling with clean 0.5–0.8 MPa air where applicable.
Transfer check: confirm no unexpected datum shift between the intended stations.
Maintenance & troubleshooting operating routine
Routine
- Each shift: clean locating faces, bores, and spigots.
- Weekly: inspect burrs, dings, seating wear, and handling damage.
- Monthly: verify the reference-stack repeatability baseline.
- Quarterly: inspect air routing, seals, and mounting fasteners.
Fast diagnosis
- Repeatability drift: clean and confirm the matched spigot.
- Slow pneumatic cycle: check pressure, filters, and lines.
- Access problem: review right-angle, side-vertical, or extension geometry.
- Station variation: standardize the mounting stack and work instruction.

Frequently Asked Questions
01. What products are included in the R-Series Datum Chuck System?
The family 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.
02. Which models are pneumatic and which are manual?
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.
03. What repeatability can I expect from the R-Series?
The four pneumatic catalog models list less than 0.003 mm repeat positioning accuracy. This value does not extend to the manual or extension formats. Use the compatibility guide and acceptance plan to verify the assembled station and transfer process.
04. When should I choose the side vertical or right-angle version?
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.
05. Can the manual R-Series chuck be used without air lines?
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.
06. What utilities do the pneumatic models require?
The pneumatic catalog models use 0.5–0.8 MPa air. The compatibility guide covers clean-air routing and access; the acceptance plan covers cycling and reference-surface checks.
07. Is the R-Series suitable for System 3R-compatible workflows?
Assess the exact System 3R-style holder, spigot, adapter and mounting geometry against the selected drawings. Pneumatic and manual R-Series formats list different spigot references; a shared family name is not proof of interchangeability.
08. Do you provide spigots, positioning plates, and setup guidance?
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.
