Calibrating the device
Fig. 10
A D40x3000 test rod is used to calibrate the VK70181000.
Just like on a roller, the components are fastened to the test rod, only
without interchangeable disc.
There is a circular groove on the target disc, which has the same
radius as the laser in the laser arm with regards to the centre line of
the test rod. By rotating the laser arm and observing the laser beam
on the circular groove, the alignment of the laser beam with the test
rod can be measured.
The fine adjustment of the laser is achieved using M5 setting nuts on
the suspension of the laser.
Furthermore, the laser beam point of the laser is adjusted using a
setting groove nut on the laser to reach the smallest laser beam point
diameter. The nut should be secured with thread lock.
