CBV/960 G-2011


Completely renewed, the edge polishing machine mod. CBV/960 G allows the processing (polishing) of marble and granite sides with different thickness by means of plates with abrasive wheels moved by spindle-motors. It is also possible to chamfer the lower and upper edges by means of spindles inclined at 45° with respect to the strips sides. The machine consists essentially of two parts: a carpentry, spindle holder structure, welded and planed, produced following the new technical concepts, to guarantee accuracy of processing, absence of vibration and high stability, and a bench made of planned steel, where the conveyor belt is installed. The pressure roller is composed of independent units with PVC wheel, pneumatically operated. Movement is controlled by PLC. Thanks to this system, you can work materials of different thickness, without any adjustment. The beam carrying spindles is equipped with motorized up-down movement. It allows the centering of the abrasive wheels according to the thickness of the material to work, with the possibility of setting the thickness on “touch screen” graphic therminal. All the water feeding pipes are dimensioned to guarantee a good inflow for the perfect dressing of the abrasive wheels. Spindles exits during the processing phases are operated by PLC. It is also possible to adjust their position to anticipate or delay the abrasive wheel outlet. The machine has two hooks to lift the whole structure. The non-deformability of the components is guaranteed during the unloading operation. The electric board is built with steel plate, thickness 15/10, painted with RAL7032. Its degree of protection is IP 55. An insulated transformer for 380V network voltage and output 48V in installed inside the electric board for all the control bodies to guarantee the safety of the operator. All the motor protective devices (fuses, magnetothermics and thermal relay) are dimensioned for each single motor to intervene in case of anomaly.

Now you can help in the development of superexpo.com and the exhibition industry!

We are asking you to help in collecting funds to extend the current form of the portal and its independence. Until now, the portal has been maintained from private funds, but we want to go ahead and grow for our users. The portal unites the entire trade show industry: it is addressed to exhibitors, organizers and visitors - we care about maintaining and transferring these mutual relations to a higher level.

superexpo team Digitization and development of the trade shows with our help is also in your hands!

Thanks to the support, we will get the opportunity to better influence on the direction of evolution and even better promotion of the industry. Superexpo.com is a place of presentation for companies and free materials for those interested, including video and 360 degree virtual tours. A professional approach in the implementation of materials and management of the portal costs us a lot of work and we would like the portal to be user-friendly and free of ads. We are aware that most people will skip our appeal, but if superexpo.com is useful to you or you believe in our mission, consider supporting our initiative.
