Hollow Spindle Stop for Spindle Ø75–96 mm – TECWERK

The Hollow Spindle Stop is a rear‑inserted clamping device for hollow spindles, designed to secure tooling by pressing the jaws against the spindle inner wall and to allow axial repositioning with a special key.

• Rear insertion with special key tightening
• Clamping range 5–96 mm
• Fits spindle Ø75–96 mm
• Adjustable axial position with release key

Precise clamping that reduces runout and improves repeatability

The device provides a secure fit by pressing the clamping jaws against the inner wall of the hollow spindle, which reduces radial play and contributes to consistent concentricity during turning and rotating operations. The clamping range 5–96 mm covers a wide variety of mandrel and tool diameters, enabling one solution for multiple set‑ups. This compact rear‑mounted design simplifies installation in machines where front access is limited, while the mechanism ensures repeatable positioning for production runs.

Simple operation and fast adjustment for workshop efficiency

Assembly is straightforward: the stop is inserted from the rear of the hollow spindle and tightened with a special key, which drives the clamping screws and activates the jaws. When axial repositioning is required, the same key releases the jaws to allow controlled movement along the spindle axis. This method eliminates the need for complex fixtures, shortens set‑up times and reduces machine downtime — a clear operational advantage for busy workshops and serial production environments.

Robust seating and safe handling minimise process interruptions

Because the jaws are pressed directly onto the spindle inner wall, the connection achieves a positive seating that resists loosening under rotation, improving safety and reducing the risk of tool run‑out. The mechanism’s design prioritises a reliable seating rather than relying solely on friction, which supports stable machining forces and consistent machining quality. This stability contributes to lower scrap rates and less rework, making the stop a pragmatic choice for quality‑conscious operations.

Wide applicability across machines and set‑ups

The configuration suits hollow spindles with outer dimensions between Ø75–96 mm while the internal clamping span permits use with small to large tool shafts (5–96 mm). The product is particularly suitable for lathe spindles and machining centres that accept rear‑mounted accessories, offering a flexible solution for turning, balancing and rotational measurement fixtures. Where space constraints or accessibility limit front mounting, this rear‑inserted stop provides a compact and practical alternative.

FAQ

What spindle diameters does the stop suit?
The hollow spindle stop fits spindles with an outer diameter of Ø75–96 mm and provides an internal clamping span from 5–96 mm, allowing versatile use across different tool shafts.

How is the device tightened and released?
Tightening and release are performed from the rear using a special key; turning the key expands the jaws to press against the inner wall and secures the stop, while reversing the action allows axial adjustment.

Is the stop suitable for production use with frequent repositioning?
Yes, the design supports repeated axial repositioning with consistent seating; the positive jaw contact reduces the likelihood of loosening under rotational loads, which is beneficial for serial production.

Which SKU identifies this product for ordering?
Order under SKU 4000832498NW; referencing this number ensures the correct hollow spindle stop from TECWERK is supplied.
