Vacuum - upto 10-5 torr or 10-7 torr
Load - from µN to 1200N
Motions - Rotary, Linear, Reciprocating
UMT-V is fully-computerized high vacuum tribometer of acclaimed design. It can perform practically all common tribological tests on all scales. The tester can also be pressurized with inert gas.
Unique Features
- Force maintained by servo control motors (not by dead weight).
- Close loop feedback.
- All motions Independently programmable (for custom wear tracks).
- Automatic Coefficient of Friction vs Load/Velocity curves generated.
- Monitors and records Insitu Acoustic emission, electrical data, friction, wear, down force, temperature, humidity etc.
- ISO, ASTM and DIN compliant.
- Simple, flexible, intuitive, easy to use windows-based software package.
Some of the typical tests routinely run on the UMT-series tribometers:
- Pin/ball-on-disc -spiral wear track or concentric wear track.
- Disc/ring-on-ring/disc with both or one of the disc/ring rotating,
- Pin/ball-on-plate with an either reciprocating or rotating or stationary upper pin/ball on an either linearly-reciprocating or stationary plate.
- Flat-on-flat with self-aligning specimen holders and at least one of them linearly-reciprocating; when both of them are linearly reciprocating in perpendicular axes, a controlled ratio of their frequencies allows for either circular (ratio of 1) or butterfly-wings (ratio of 2) or other programmable wear track patterns.
In all these and numerous other tests, the UMT-V can perform an automated synchronized control of several specimen motions with linear speeds from 0.1 micron/s to 30 m/s (7 orders of magnitude!) and angular speeds ranging from 0.001 to 7,000 rpm, under the precision loads from Micro N to 1.2 kN. In these unprecedented wide ranges, the UMT-V can automatically monitor a number of process parameters in-situ with a high sampling rate.
