The dynamometer has a great rigidity and consequently a high natural frequency. Its high resolution enables the smallest dynamic changes in large forces to be measured.

• Universal applicable
• For cutting force measurements
• Stable and reliable

Description

The dynamometer consists of four three-component force sensors fitted under high preload between a baseplate and a top plate. Each sensor contains three pairs of quartz plates, one sensitive to pressure in the z direction and the other two responding to shear in the x and y directions respectively. The force components are measured practically without displace- ment. The outputs of the four built-in force sensors are connected inside the dynamometer in a way to allow multicomponent measurements of forces and moments to be performed. The eight output signals are available at the 9-conductor flange socket. The four sensors are mounted ground-insulated. Therefore ground loop problems are largely eliminated. The dynamometer is rustproof and protected against penetra- tion of splashwater and cooling agents. Together with the con- necting cable Type 1687B5/1689B5 and Type 1677A5/1679A5 it corresponds to the protection class IP67. A special thermal isolation coating is integrated in the top plate which renders the dynamometer largely insensitive to temperature influences. Application examples

• Dynamic and quasistatic measurement of the three orthogo- nal components of a force
• Measuring cutting force when turning, milling, grinding etc. In conjunction with the calibrated partial ranges the high sensitivity and low threshold allow exact measurements on small tools and when grinding.

Dimensions milling, grinding Fig. 1: Dimensions dynamometer Type 9257B Dimensions turning Fig. 2: Dimensions dynamometer Type 9257B with mounted tool holder Type 9403 Mounting The dynamometer may be mounted with screws or claws on any clean, face-ground supporting surface, such as the table of a machining tool for example. Uneven supporting surface may set up internal stresses, which will impose severe ad- ditional loads on the individual measuring elements and may also increase cross talk. For mounting the force-introducing components, such as lathe tools and workpieces, fourteen M8x1,25 mm blind tap 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 26x26 mm shank cross section, the tool holder Type 9403 may be used. This holder is not included in the standard accessories and must therefore be ordered separately. Type 9403 Type 1689B5 Type 1687B5 Type 9403
