Product Introduction
The Renishaw TS27R (A-2008-0368) is a standard, radio-free contact tool setting probe designed for CNC machining centers. This specific kit is optimized for setting tool length and diameter directly on the machine table, eliminating the need for external presetters. It includes the essential 12.7mm disc stylus, making it highly effective for measuring rotating tools without causing wear to the stylus or the cutter.For maintenance teams, sourcing a verified A-2008-0368 kit means reducing machine downtime significantly. Every unit we ship undergoes a strict 24-hour functional test on a dedicated test rack. Field data shows that replacing a worn or damaged probe with a calibrated TS27R can restore tool setting accuracy to within microns, preventing costly scrapped parts due to undetected tool breakage.
Installation & Configuration Guide
Phase 1: Preparation (10 min)
- Ensure the machine is in E-STOP mode.
- Clean the machine table mounting surface thoroughly. Any chips or burrs will affect repeatability.
- Verify you have the correct interface (MI8-4) if your machine requires hard-wired signal conversion.
Phase 2: Removal of Old Probe (5–10 min)
- Disconnect the interface cable from the old probe.
- Unbolt the holder from the machine table.
- Note: If the old stylus is damaged, inspect the holder for scratches. Deep scratches might affect the seating of the new unit.
Phase 3: Installation (10 min)
- Mount the new A-2008-0368 holder assembly onto the table using the provided fixings.
- Insert the Probe Module into the holder. You should feel a positive click.
- Attach the 12.7mm Disc Stylus. Ensure the weak link protection device is seated correctly (this is crucial for collision safety).
- Connect the interface cable to the MI8-4 interface and route it safely away from moving parts.
Phase 4: Power-On & Test (10 min)
- Release E-STOP and power up the CNC controller.
- Run a basic macro call (e.g., M-code for tool setting) to verify the probe triggers.
- Check the “Probe Status” LED (if equipped on the interface) or monitor the input signal on the PLC diagnostics page.
- Perform a manual trigger test by gently pushing the stylus. The machine input should toggle immediately.
Troubleshooting Quick Reference
| Issue | Probable Cause | Quick Check / Fix |
|---|---|---|
| Probe not triggering | Weak link disengaged | Check if the stylus protection “weak link” has popped out. Re-seat it gently. |
| False triggers | Dirty stylus/holder | Clean the disc stylus and the probe seating area with isopropyl alcohol. |
| No signal to CNC | Interface fault | Verify the MI8-4 interface LED status. Check cable continuity. |
| Inconsistent measurements | Mounting surface dirty | Remove probe and clean the table mounting surface. Re-torque bolts. |
| Stylus wear | High RPM contact | Ensure the disc stylus is rotating freely (if applicable) or reduce approach speed. |
Dimensions, Mounting & Wiring Notes
- Mounting: Standard machine table bolt pattern (check specific holder dimensions in the TS27R manual).
- Wiring: Hard-wired connection via MI8-4 Interface. Ensure the cable is not pinched or stretched during axis travel.
- Stylus Note: The 12.7mm (0.5 inch) disc stylus is designed for measuring flute lengths and diameters of rotating cutters. Do not use excessive force when manually jogging the tool into the stylus.
FAQ
Q: Does the A-2008-0368 kit come with the MI8 interface?
A: No. The A-2008-0368 kit includes the Probe Module, Holder, Weak Link protection, and the 12.7mm Disc Stylus. The MI8-4 Interface is sold separately (often part of the A-2008-0397 kit or ordered individually). Please check your current machine setup to see if you already have the interface box.Q: I have a Fanuc controller. Will this work?
A: Yes, the TS27R is widely compatible with Fanuc controls, typically using Macro B. However, you will need the correct macro program loaded into the CNC. We can provide the standard macro code upon request.Q: Is this an original Renishaw product?
A: Yes. We supply verified authentic Renishaw products. Every unit undergoes an incoming inspection to check for OEM markings and build quality. We do not sell “compatible” or “clone” probes.Q: What is the “Weak Link” protection?
A: It’s a mechanical fuse. If a tool accidentally crashes into the probe, the weak link disconnects the stylus module to prevent expensive damage to the internal probe mechanism. It’s easy to reset—just push it back in.Q: Can I use this for part inspection?
A: While the TS27R is primarily designed for tool setting, it can be used for basic part positioning. However, for high-precision part inspection, we recommend Renishaw’s OMP or RMP series probes which offer higher accuracy and different stylus options.Q: What if the probe arrives and doesn’t trigger?
A: It’s rare, but if it happens, check the weak link first (it might have disengaged during shipping). If it’s still not working, contact us within 3 days. We provide a warranty and will replace any unit that fails our pre-shipment test standards.
