System 3R-Compatible Datum Chuck Family
R-Series Datum Chuck for CNC, EDM & Inspection Transfer
Manual and pneumatic datum chucks for repeatable transfer between machining, EDM, presetting and inspection.
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
When one datum family must move across more than one station
A strong route for shops that want the same reference logic shared between CNC, EDM, presetting, inspection, and later automation upgrades.
Selection prep
Lock the chuck style before comparing every model
The fastest qualification usually comes from deciding pneumatic vs manual, top vs side air access, and whether right-angle or extension geometry is needed.

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. Then confirm the complete chuck, spigot, plate, and machine interface with engineering.
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
Confirm the complete datum stack before ordering
The chuck body is only one part of the result. Lock the matched spigot, rigid mounting base, utilities, clearance, and acceptance method for every station that will share the datum.
Interface match
Confirm the R-Series chuck, matching spigot, positioning plate, table pattern, and stack height as one controlled 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
Define re-clamp, seating, and station-to-station transfer checks against your own process tolerance before release.
Catalogue & project files
Use the gated catalogue for the family overview; available CAD and drawings are confirmed for the selected configuration.
Product Details
One datum family, multiple chuck formats, and cleaner transfer between machines and stations.
One system for different machine layouts
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.
Designed for repeatable transfer and practical maintenance
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
Four R-Series chuck bodies on the same datum
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.

Application Fields
The R-Series family supports different layouts, not just different industries.
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.
Typical R-Series Workflows
EDM electrode & holder standardization
This workflow 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.
4-axis / 5-axis fixture access improvement
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.
Manual presetting for faster machine changeovers
In this workflow, 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.
Commission with evidence

Start the R-Series RFQFrequently Asked Questions
01. What products are included in the R-Series Datum Chuck System?
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.
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 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.
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 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.
07. Is the R-Series suitable for System 3R-compatible workflows?
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.
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.
