RENISHAW 06-0439 Replacement Stylus M4, Ruby Ball Ø 6mm, Ceramic, Range Length 50mm

Buy online your RENISHAW 06-0439 Replacement Stylus M4, Ruby Ball diameter 6 mm, Ceramic, Length 50 mm from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The RENISHAW 06-0439 is a precision probe stylus designed for coordinate measuring machines (CMMs) and CNC machine tool probing systems. Used for workpiece setup, dimensional inspection, and part verification, it provides a reliable replacement solution for probing equipment utilizing an M4 interface.

This stylus features an M4 thread compatible with a wide range of RENISHAW probe heads, extensions, and modules. It is fitted with a 6 mm ruby ball that provides a consistent and repeatable contact point, while the ceramic stem combines low mass with excellent rigidity to support stable measurement performance. With an overall length of 50 mm, it offers convenient access to bores, faces, datum features, and other common inspection points encountered in metrology and production environments.

The RENISHAW 06-0439 is widely used for part location, in-process inspection, and final quality control operations. Its design supports reliable triggering and repeatable measurement results, helping maintain accuracy throughout the inspection process and reducing the risk of measurement variation.

In maintenance applications, this stylus is commonly replaced when the ruby tip becomes worn or damaged, or when the stem is bent and affects calibration accuracy. Installation is straightforward, and a routine probe recalibration allows the measurement system to quickly return to full operating performance.

Manufactured in the United Kingdom, the RENISHAW 06-0439 meets the requirements of industrial measurement applications and is frequently stocked as a spare part to minimize downtime. Units can be inspected prior to shipment and are supplied in protective packaging suitable for industrial transportation. Standard warranty coverage is available, and repair or exchange solutions may be offered depending on availability.

Frequently asked questions about 06-0439:

Which probes does this M4 stylus fit
It fits RENISHAW probe heads, modules and extensions that use an M4 female thread. If you are unsure, check the thread specification of your probe assembly or share the probe model with our team for confirmation.

Do I need to recalibrate after swapping this stylus
Yes. After any stylus change you should run the standard probe calibration routine so the control compensates for ball diameter and center offset. This ensures measurement repeatability before resuming production checks.

When is a 6 mm ruby ball a good choice
A 6 mm ball is a versatile size for general workholding features, faces and medium bores where a stable contact area is preferred. It balances access and robustness for routine inspection on common machined materials.

Is the ceramic stem suitable for shop-floor use with coolant
The ceramic stem and ruby sphere are well suited to typical shop conditions. Wipe the tip clean before calibration and measurement to maintain consistent triggering on the probe.

What is the usable reach relative to the 50 mm overall length
Overall length is 50 mm measured to the thread. Effective working reach depends on the mounting stack and ball radius, so verify clearances in your setup and adjust extensions only as needed to maintain rigidity.
