Friktion testmaskine model 205

Friction coefficient testing machines by TesT of model series 205 are market-leading, equipped with patented components and always built according to most modern test methodologies. Thus, TesT has created an instrument for safe and fast testing of screw connections for screws and bolts of M3 to M80. The determination of friction coefficients is in the focus of analysis.

TesT is market leader in this field of application and has already supplied numerous machines. In collaboration with well-known manufacturers of screws, nuts and coating materials, as well as with important large-scale users of the automotive industry and their subcontractors we have brought to market numerous innovations and patents, particularly in the area of screw tests.

Data evaluation is made online in the corresponding software TesTWinner® and in accordance to the applicable standards. Different international standards or companies internal standards may be stored and used alternatively. Own customer specific requirements can be integrated into the software sequences and calculations. Showing the friction coefficient curve is an additional specific feature of the software.

Optionally can be integrated into the system:

• Extensometers
• Thermo chamber to heat the screw (patented)
• Ultrasonic extensometers
• Adaptation for tension bolts

Friktion testmaskine model 205

Our friction testing machines, equipped with the patented multi-component-sensors have entered the world market. All national and international standards, as well as every company standard specification will be respected. The measured and calculated forces, torques and angles are basics to show the friction coefficients at screws, bolts, nuts and components. Due to these information fixation parts can be used in that way, that an op- timized and safe fixation is assured.

Multi-Component Sensors

The patented multi-component sensors allow measuring the strain occurring by tension force and torque inside the screw individually. They transmit the decoupled measurement values to the force sensor and to the torque sensors. Additionally, the necessary angle will be measured with a high reso- lution inside the machine.

Application areas are primarily in automotive indus- try, at car and truck manufacturers, in fastener in- dustry, big mechanic construction, power engines and particularly for wind power stations.
