Pedrini M744LV-2/3/4 - Edge trimming machine for marble, travertine, granite slabs and strips

This machine performs the longitudinal cuts of marble or granite slabs into strips with predetermined length by means of diamond discs. It is equipped with a variable number of discs and with different automation levels and powers according to the production needs.
M744 is available also in the version for marble and granite strips with 2, 3 or 4 discs.
Pedrini M744 trimming machines perform the longitudinal continuous cutting of marble or granite strips and slabs to produce elements with defined width.
All Pedrini M744 trimming machines are available in several versions and with different automation levels.
On demand, M744 machines can be manufactured in special versions to cut semi-finished products having different sizes compared to the standard.
Trimming machines M744LV are normally used for the trimming of up to 650 mm wide strips of marble and granite.
Whether used individually or included in a production line, M744LV can be equipped with a different number of discs to enable different processing:
. with 2 discs it allows to trim strips to get the final width;
. with 3 discs it allows to trim and get two strips from a single strip;
. with 4 discs it allows to trim and get three strips from a single strip.
Trimming machines M744LD, M744MD and M744KD are particularly suitable for high production cutting lines for marble and granite slabs.
Trimming machines for slabs can be equipped with a different number of disc holder heads according to the minimum processed sizes (5, 6, 7 or 8) and to the slabs width.
As option, the first disc holder head can be mounted in an opposite position to the others so to recover undersized elements from the remaining waste.
A special double-coated rubber belt moves the slab to the machine entry.
Special guides keep the conveyor belt straight movement ensuring the cuts linearity.
The disc holder heads are directly selected from the control panel. The heads which are not used are excluded by means of a pneumatic system without removing the disc.
After the execution of the cuts, on request, a special waste crushing unit is mounted at the machine exit allowing to cut the waste into small pieces facilitating its fall on the removal conveyor belt.
