CL stands for contact line, CP for contact point. The difference between the two can be dramatic depending on the material. Old-line band saws (CL) enter the sample at the top and continue through the sample until exiting at the bottom. The active cutting surface is a line at any point.
In CP technology the sample is automatically rotated during cutting so
that only a small portion of the sample is in contact with the active
cutting surface at any time, thus the term "contact point".
All of EXAKTs cutting systems are available with CP capability.
The CP advantages are:
For fast, accurate cuts without metal distortion in applications that
include rubber or polymers bonded to metal try the EXAKT 300 CP with the
reversing tool feature. With EXAKTs capability to reverse the tool
direction on its band and rotary systems, the customer can reduce the
"pulling" effect that "single direction" tools have
on metal. The outcome is a clearer interface, greater structural integrity
of the metal and faster cutting times.
Recognizing that some materials are so soft that even a very low constant feed force can be excessive, EXAKT provides a system with a constant feed rate mechanism to further inhibit the force at the cutting surface. The CPV option enables the researcher to further slow the rate of cutting if the force at the cutting surface becomes too great. This option is only available on the Band Systems.
With the addition of the CPVS parallel motion saddle, it is possible to make serial cuts without operator intervention. This option is only available on the EXAKT 310 CPVS Band System.
