Dynamometer Piezoelectric "Kistler Type 9121"

Description:

The multicomponent dynamometer provides dynamic and quasi-static measurement of the 3 orthogonal components of a force (Fx,Fy,Fz) acting from any direction onto the top plate.With the aid of options evaluatuion devices the drilling moment can be measured as well. The dynamometer has high rigidity and hence high natural frequency. The high resolution enables very small dynamic changes to be measured in large forces

The dynamometer measures the actives cutting forces regardless of its application point. Both the average value of the force and the dynamic force increase may be measured. The usable frequency range depends mainly on the resonance frequency of the entire measuring rig

Dynamometer application:

r Cutting force measurements during turning and drilling on revolver lathes

High sensitivity and calibrated partial ranges allow accurate measurements on small tools.

Profilometer "Hommeltester T1000"

Description:

The Hommel Tester  T 1000 represents a modern, easy to handle, portable. Measurement preparation and measuring runs are carried out with 4 electronic membrane switches. Calibration on a regular basis is no longer needed as the central micro-processor retains a fixed value against which measured profiles are evaluated. All parameters and measured values are displayed on a large, 8 digit LCD display.

A number of standard surface roughness parameters (Ra, Rz, Rt, Rmax, tpi, tpa, etc) are available for determining the magnitude of surface flaws and characterizing the surface profile.Dependent upon type of parameter meadured, these are calculated from the unfiltered, measured profile, the filtered roughness profile or the filtered waviness profile.

The benefit of measuring surface topography is to detect surface flaws which are generated by the manufacturing process. This allows specific steps to be taken to hold the surface finish within tolerances permitting the correct function of the part. It should be remembered though, that the task of surface measurement is not to create as smooth a surface as possible. A highly finished surface is far more expensive to manufacture and may also function less well than a rougher surface..

Shop Microscope "Mitutoyo TM-500"

Description:

The Mitutoyo Measuring Microscope TM-500  are easy-to-use, compact-size measuring microscopes that feature a vertical supporting column. Designed with measurement of workpiece contours and inspection of surface features in mind, the TM 500 suports a wide range of applications from shop-floor inpection, measurement of tools and machined parts, to precision measurements of test tools in a measuring room
