Hollow Spindle Stop (for spindle Ø 58–76 mm) — Rear-insert design, adjustable axial clamp — TECWERK

A Hollow Spindle Stop designed for rear insertion into a hollow spindle, providing secure internal clamping and fine axial adjustment for machining applications

• Rear-inserted design for compact spindle assembly
• Secure internal clamp via expanding jaws
• Adjustable length with special tightening key

Precise internal clamping for repeatable positioning

Installed from the spindle rear and tightened with a special key, the device converts axial torque into radial expansion so that the expanding jaws press against the spindle bore. This mechanism produces a secure fit with consistent concentricity, supporting reliable axial positioning and repeatability. The controlled radial contact reduces run-out and contributes to improved surface quality, which is particularly advantageous in operations where minimal deviation is critical.

Fast adjustment and compact installation to reduce downtime

Loosening and re-positioning are achieved with the same key, allowing the stop to be slid axially for quick length calibration or removal. Because the clamping action is internal, no external fixtures are needed and spindle overhang is minimised, helping to preserve balance during rotation. The compact installation therefore shortens set-up times and simplifies maintenance routines while maintaining stable clamping performance.

Broad compatibility and practical workshop advantages

Engineered for hollow spindles with an effective diameter window of 58–76 mm, the stop accommodates a wide range of mandrels within its 8–76 mm clamping envelope. The design emphasises a secure seating and straightforward serviceability, which helps to limit machine downtime during tool changes. Supplied through TECWERK and distributed by Metav Werkzeuge, the device combines pragmatic durability with workshop convenience for both single-piece work and serial production contexts.

FAQ

What spindle diameters is this stop suitable for?
The hollow spindle stop is intended for hollow spindles with an effective diameter of 58–76 mm; the internal clamping envelope spans 8–76 mm (TECWERK, SKU 4000832506NW).

How is the stop tightened and released?
Tightening is performed from the rear with a special key: turning the clamping screw expands the jaws against the spindle bore; the same key is used to release and slide the stop axially.

Does the design require external fixtures?
No external fixtures are required; the internal expanding jaws secure the device inside the spindle, preserving compact installation and spindle balance.

What operational benefits does the stop provide?
The internal clamping method reduces run-out and overhang, improving concentricity and contributing to better surface finish and repeatability during machining.
