Choose NT-S500P50 when

You machine one blank per cycle, need the smallest pneumatic dovetail footprint on a compact table, or want a dedicated single-station fixture for short runs and prototypes.

Choose NT-S600P90 when

You want to run three identical or similar parts per cycle to maximize spindle uptime, reduce per-piece load/unload time, and raise throughput on a single machine table.

Dovetail jaw selection (6583-Z series)

The 6583-Z4 through Z16 jaws cover 10.5 mm to 34.5 mm dovetail widths. Select the jaw size based on blank thickness and desired clamping envelope — Z4/Z6 for thin plates, Z12/Z16 for thicker stock up to 100 mm.

Five-Side Machining Efficiency

The dovetail fixture clamps the workpiece along a small 45° dovetail, leaving the top, front, back and two sides completely unobstructed for cutting. This design enables true five-side machining in a single setup and reduces the extra material normally required for gripping, saving both time and raw material costs.

Precision & Repeatability

Each dovetail fixture is fitted with precision locating pins and ground reference surfaces to eliminate slide and ensure high repeatability when swapping parts. Combined with the rigid dovetail geometry, this guarantees consistent machining accuracy and surface finish.

Patented design for small plate processing on 3/4/5-axis machines.
Adjustable clamping position with selectable pressing plates.
Support column with scale adjustment for precise hold-down placement.
Side U-shaped groove avoids tool interference during side machining.
Optional 3R or Erowa spigot positioning interfaces.

Modular & Zero-Point Compatible

The base of the fixture is machined to industry-standard 52 mm and 96 mm patterns, making it directly compatible with zero-point clamping plates, quick-change systems and automation pallets. This modularity streamlines setup changes and allows multiple fixtures to be mounted in high-density arrays for increased throughput.

Applications & Use Cases

System 52 vs System 96: quick decision table

Use this decision matrix when you’re choosing a 45° dovetail fixture for 5-axis machining and a zero-point clamping stack. It’s a fast way to align part size, cutting load, and automation needs.

System 52 vs System 96: quick decision table — technical data
Consideration	System 52	System 96	What to verify
Part size & handling	Small to mid-size parts; higher station density on a compact plate.	Mid to larger parts; more base area for stable docking on pallets.	Machine envelope, pallet size, and how you load (manual/robot).
Cutting load & rigidity	Great for general milling and lighter roughing; optimize toolpaths to keep forces balanced.	Best when you need maximum stiffness for heavier roughing or tougher materials.	Stock removal rate, tool length, chatter risk.
Automation / palletization	Lower mass helps robots and quick swaps; ideal for high-mix cells.	More stable on larger pallets; preferred for lights-out cells with heavier parts.	Receiver/pallet compatibility and repeatability after swaps.
Chip & coolant clearance	Compact layouts can pack stations tightly—plan chip evacuation carefully.	More spacing options for shields, air blast, and chip evacuation.	Coolant direction, chip buildup risk, cleaning routine.
Typical use cases	Prototype → production, small housings, thin-wall/window-style parts, high-density arrays.	Larger brackets, tougher alloys, higher torque cuts, palletized production.	Target tolerance, surface finish, and cycle time goals.

Tip: If you’re building a palletized cell, pair the fixture with a zero-point plate so stations can be exchanged without re-indicating.

When to choose System 52

Best for small to mid-size parts, tight machine envelopes, and high-density arrays. Great for quick prototype-to-production changeovers on 3-axis/4-axis/5-axis machines.

High station density on a compact plate
Fast swapping on System 52 zero-point receivers
Lower mass for rapid robot handling

When to choose System 96

Use System 96 for heavier cuts, larger parts, or when you need maximum rigidity on pallets and automation cells.

Wider base improves stability
Pairs well with larger zero-point plates/pallets
More room for stops, locators, and chip evacuation

Automation & palletization tips

For lights-out production, combine a dovetail fixture with a zero-point plate and pallet changer so stations can be exchanged without re-indicating.

Combine with a pneumatic zero-point plate to eliminate re-indicating between setups
Add an automatic pallet changer for unattended lights-out shifts
Run multiple fixtures per pallet to keep the spindle cutting while setups happen off-machine

5-Side Machining Best Practices

A clean, consistent 45° dovetail is the difference between “it holds” and “it runs production.” These steps help you get stable clamping and predictable cycle times.

1. Machine a consistent 45° profile

Use a matching dovetail cutter and keep the depth consistent across batches. Deburr the profile so the fixture seats fully.

2. Control part distortion

Clamp close to stiff regions. For thin or window-style parts, use support columns/pressing plates to avoid bending.

3. Validate with a trial cut

Run a short rough+finish program, then check key datums. If needed, add stops/locators to prevent axial slip.

4. Keep interfaces clean

Chip contamination is the #1 enemy of repeatability—clean the dovetail and the zero-point interface before every swap.

Next step

Share your part size, material, and machine model. We’ll propose a proven 45° dovetail workholding setup (fixture size, station layout, and zero-point stack) to match your tolerance and takt time.

Troubleshooting & Repeatability

Even a great 45° dovetail fixture can lose repeatability if chips, distortion, or excessive tool load creep in. Use this quick table to diagnose the most common issues in 5-axis dovetail workholding and zero-point setups.

Troubleshooting & Repeatability — technical data
Symptom	Likely cause	Recommended fix
Part slips during roughing	Dovetail profile inconsistent, clamp not seated, or cutting forces too aggressive.	Re-cut the 45° profile, deburr, and reduce tool engagement; add stops/locators if needed.
Chatter / vibration marks	Insufficient rigidity, long tool reach, or resonance at high RPM.	Switch to System 96 or reduce overhang; tune feeds/speeds; use shorter tools and balanced toolpaths.
Thin walls distort	Clamping near flexible regions or uneven support on window-style parts.	Clamp closer to stiff ribs; use support columns/pressing plates; verify distortion after a trial cut.
Z height shifts after swapping	Chips on the dovetail or on the zero-point interface; coolant film.	Clean both interfaces every swap; add air blast/brush at load station; keep receivers dry and protected.
Marks on the dovetail	Burrs, too much clamping pressure, or poor surface condition.	Deburr and add a small lead-in chamfer; use correct clamp force; consider sacrificial dovetail pads.
Repeatability degrades over time	Wear, contamination, or damaged locator pins.	Inspect pins and contact surfaces; replace worn inserts; schedule periodic cleaning and calibration checks.

If you’re running lights-out production, pair this fixture with a pneumatic zero-point plate and pallet changer so docking is consistent across stations.

Selection • Integration • Maintenance Cheatsheet

The 5-axis dovetail fixture grips raw stock with a 45-degree dovetail profile, exposing five sides for machining in a single setup. This cheatsheet covers dovetail depth and material selection, integration onto zero-point plates, and maintaining consistent grip force and surface finish over long production runs.

1) Selection: pick the right configuration

1) Selection: pick the right configuration — technical data
If you care most about…	Start with…	Why this helps
Maximum 5-side access on small parts	52 mm dovetail fixture—low profile, minimal obstruction for short-reach tools.	Keeps the grip zone below the finished part envelope so the cutter never hits the fixture.
Larger or heavier blanks	96 mm dovetail fixture with deeper dovetail engagement and higher grip force.	Prevents pull-out during aggressive roughing on tall workpieces.
Soft materials (aluminum, brass, plastics)	Shallower dovetail cut (1.0–1.5 mm) with lighter clamp torque.	Avoids crushing the material or leaving deep witness marks that waste stock.
Hard materials (steel, titanium, Inconel)	Full-depth dovetail (2.0–3.0 mm) with maximum clamp engagement.	Resists the higher cutting forces without workpiece rocking or chatter.

2) Integration: what to prepare before install

2) Integration: what to prepare before install — technical data
Item	Typical choice	Practical tip
Dovetail cutter selection	Use the recommended 45° dovetail end mill; match diameter to fixture jaw width.	A worn or incorrect cutter angle produces a sloppy fit and reduces grip force.
Zero-point plate mounting	Bolt the dovetail fixture onto a 52 or 96 mm zero-point plate with dowel pins.	Combining dovetail + zero-point gives you fast fixture swap and five-side access in one stack.
Workpiece prep (dovetail milling)	Mill the dovetail profile on Op 1 (vise or soft jaws); transfer to dovetail fixture for Op 2.	Keep the dovetail cut consistent—variation in depth directly affects grip force and Z datum.
5-axis clearance check	Simulate the full toolpath with the fixture model to verify no collision at extreme tilt angles.	The fixture jaw height sets the minimum Z clearance—account for tool holder and spindle nose.

3) Maintenance: keep repeatability stable

3) Maintenance: keep repeatability stable — technical data
Risk / wear point	Early symptom	Prevention / quick fix
Jaw face wear from repeated clamping	Grip force drops; workpiece shifts under cutting load.	Inspect jaw faces every 500–1,000 clamp cycles; resurface or replace jaws when wear exceeds 0.02 mm.
Chip packing in the dovetail groove	Part won’t seat fully; Z datum shifts upward.	Blow out the groove with an air gun before every load; avoid flood coolant aimed directly into the groove.
Clamp screw thread wear	Screw feels loose at rated torque; clamp force inconsistent.	Apply anti-seize to threads; replace the screw when torque-to-force relationship drifts beyond spec.
Corrosion on jaw faces (coolant or humidity)	Surface pitting reduces friction; part slips during heavy cuts.	Wipe jaws dry at end of shift; store unused fixtures with a light oil film or VCI wrap.

Frequently Asked Questions

How much material do I need to prepare for the 45° dovetail?

For optimal clamping, prepare a 45° dovetail on the raw stock with a depth of about 3–5 mm. This small engagement delivers strong pull-down holding while keeping five faces open for machining, reducing stock waste versus traditional vises.

What is the primary difference between the 52 mm and 96 mm dovetail fixtures?

It’s mainly the mounting pattern and scale. System 52 is great for smaller parts and high-density setups. System 96 offers a wider footprint and pairs with larger zero-point plates/pallets for heavier parts and maximum stability.

Can I use these dovetail fixtures on a 3-axis or 4-axis machine?

Yes. Even on 3-axis/4-axis machines, dovetail workholding improves rigidity and tool access, and it speeds up changeovers—especially for high-mix production.

What dovetail angle and cutter do you recommend?

The fixtures are designed around a 45° dovetail. Use a matching dovetail cutter sized to your stock and leave a clean, burr-free profile. If you’re unsure, share your part drawing and material and we’ll recommend a proven dovetail spec.

How does this dovetail fixture compare to a self-centering vise for 5-side machining?

A self-centering vise grips two parallel sides, which blocks tool access and needs taller stock. A dovetail fixture grips a small 45° profile at the base, creating pull-down clamping and leaving five faces unobstructed—ideal for true 5-side machining.

How do I prevent part pull-out or vibration during aggressive machining?

Keep overhang low, ensure the dovetail is consistent and deburred, and match fixture size to load (System 96 for heavier cuts). For high torque operations, add stops/locators where needed and validate the process with a trial cut and inspection.

Is it suitable for thin plates or window-style parts?

Yes. For thin or window-style parts, use the appropriate pressing plates/support columns and place the clamp point close to the stiffest area of the part to minimize distortion.

How repeatable is swapping parts when combined with a zero-point plate or pallet?

Repeatability depends on the zero-point base and your dovetail consistency. With clean interfaces, consistent dovetail prep, and proper seating, many shops can swap parts quickly with minimal touch-off—always verify to your tolerance requirements.

What kind of maintenance do these fixtures require?

Blow chips out of the clamping interface regularly, keep contact surfaces clean, and lightly lubricate threaded elements to prevent galling. Periodically check wear items (screws/pins) and replace as needed.

Are the clamping components and locating pins replaceable?

Yes. Wear components such as clamping screws and locating pins are field-replaceable, helping you maintain consistent performance over long service life.

What is the typical lead time from confirmed PO to shipment?

Standard dovetail fixtures ship 4–6 weeks after PO confirmation. Custom dovetail angles, matched pairs, or pre-machined soft jaws add 1–2 weeks. Committed lead time is confirmed in writing once the dovetail spec, jaw width, and serial configuration are locked.

What inspection and quality documentation ships with each dovetail fixture?

Each dovetail fixture ships with a factory inspection report covering dovetail angle accuracy, jaw parallelism, and clamping-force measurement at the rated input. Material certificates for the hardened body, calibration records, and the written warranty are available on request at order time.
