Renishaw MP 11 probe

R enishaw MP 11 probe

The Renishaw MP 11 is a wired probe specifically designed for CNC machine tools with manual tool changes. This probe enables significant productivity gains through fast and precise part setup and inspection directly at the machine.

Technical data:

• Measuring directions : ±X, ±Y, +Z
• Unidirectional repeatability : 1.0 µm (40 µin) at a test speed of 1000 mm/min (3.28 ft/min) with a 50 mm (1.97 in) long stylus.
• Stylus trigger force :
  • X and Y directions: 0.50 to 1.5 N (50 to 150 gf, 1.76 to 5.29 ozf)
  • Z direction: 1.8 to 7.0 N (180 to 700 gf, 6.35 to 24.69 ozf)
• Stylus overflow (maximum deviation) :
  • X/Y: ±17.5°
  • Z: 8 mm (0.31 in)
• Stylus lengths :
  • Default: 50 mm (1.96 in)
  • Optional: Other lengths available up to 75 mm (2.95 in)

Features:

1. Direct signal transmission to the CNC machine control :
   • An interface unit is integrated in the probe head and processes signals between the probe and the machine control. The signals are transmitted via a spiral cable.
2. Visual display of button status :
   • An illuminated LED goes out as soon as the probe touches the workpiece.
3. External stylus spring pressure adjustment :
   • Allows for quick and easy adjustment, especially useful when using heavy stylus combinations.
4. Stylus centering :
   • Adjustment screws in the shaft allow the stylus to be aligned with the spindle center axis.
5. Flexible assembly :
   • Can be mounted like any other tool in the system. Renishaw offers a variety of shanks modified to accommodate the MP 11 probe.

Safety and operating instructions:

• Spindle rotation lock :
  • It is recommended to incorporate a fail-safe spindle rotation lock into the system to ensure that spindle rotation is automatically prevented when the probe is in use.
• Protection and storage :
  • A special storage box protects the button when it is not in use.

Areas of application:

• Component setup :
  • Reduces machine downtime through automatic fixture alignment and part setup.
• Inspection :
  • Enables in-cycle measurements and first part tests with automatic correction of offset values.
• Tool setup and breakage detection :
  • Precise measurement of tool length and diameter as well as detection of tool breakage during the cycle.

Condition and scope of delivery:

This device is used but fully functional and was taken from a running system. The wiring must be adapted to the machine to be installed and is not included in the scope of delivery. The scope of delivery is as shown in the photos and includes components such as the Festo pneumatic cylinder.

The Renishaw MP 11 thus offers a comprehensive solution for increasing the efficiency and accuracy of CNC machining centers with manual tool changes. Further details can be found on the relevant product pages in German.
