Type 9272 Four-component dynamometer for measuring a torque Mz and the three orthogonal components of a force. The dynamometer has a great rigidity and consequently a high natural frequency. Its high resolution enables the smallest dynamic changes in large forces and torques to be measured.

• Compact and robust multicomponent force measuring instrument
• Suitable for cutting force measurements when drilling
• Universal use

Description

The dynamometer consists of a four component sensor fitted under high preload between a base plate and a top plate. The four components are measured practically without dis- placement. It must be taken into account that combined and eccentric loads may reduce the measuring ranges. The sensor is mounted ground-isolated. Therefore ground loop problems are largely eliminated. The dynamometer is rustproof and protected against penetra- tion of splash water and cooling agents. Together with the connecting cable Type 1677A5/1679A5 it corresponds to the protection class IP 67. Application examples

• Measuring feed force, deflective force and moment when drilling, threadcutting etc.
• Cutting force measurements while milling and grinding
• Cutting force measurements while turning
• Testing torque wrenches
• Testing springs (torsion)
• Measurements on small thrust bearings, friction clutches etc.
• Measuring starting torques on fractional horsepower and stepping motors

Uneven supporting surface may set up internal stresses, which will impose severe additional loads on the sensor and may also increase crosstalk. For mounting the force-introducing components, such as lathe tools and workpieces, eight M8 mm threaded holes in the cover plate are available. The supporting surfaces for the force-introducing parts must be face-ground to obtain good mechanical coupling to the cover plate. For satisfactory mounting of lathe tools up to 20x20 mm shank cross section, the tool holder Type 9404 may be used. This holder is not included in the standard accessories and must therefore be ordered separately.
