Recently, in chainsaw cutting, we developed and patented a new typology/sequence in order to reduce the impact of diamond cost in chainsaw cutting, while increasing the PDC’s shock resistance, productivity and stability of the chainsaw.
The stability of the chainsaw, combined to patented geometry of the tool holders have led to longer chainsaw’s lifetime (fig.1:
Diamond chainsaw Revolutionnary, more stable and more productive).
This has been achieved with the cooperation of the University of Mons (Belgium).
By mean of a new software program, we have been able to compute the efforts/forces on every cutter of the chain saw, and work on a better distribution of the forces (fig.2).
This new “ideal/theoretical” distribution has been tested (
etau limeur) at the University’s Lab to confirm the values.

WE developed also a field instrumentation to be mounted on the chain saw machine in order to correlate/compare with Lab values and monitor field values (fig.3).
By monitoring the critical operating values (cutting speed, RPM, working pressure, chain circuit pressure, vibrations level and chain saw tension), more details in
the "cinematic du bras" and
the "PMDS Concave Trait 24/06/10" (size:1,3 M., .pdf), we
have succeeded to confirm the Lab values and optimize the working parameters: we achieved a 40% increase in productivity (
mai2009 vs mai2010).
Furthermore, we were able to reduce the diamond impact/cost in the chain saw, which brought a 50% reduction in total chain sawing production costs.
This mobile instrumentation can be hired on a daily basis, and allows the comparison between actual customer field working parameters and PMDS new typology parameters.
A calculation sheet of total production costs is produced in order to calculate the costs savings
