Designing automatic machines for buffing and satin finishing metals other surfaces. We have the longest expertise in this process and one of our key knowledge.
Composed of indexed rotary tables or continuous motion tables, they may be equipped with a vast selection of buffing units featuring different degrees of complexity, flexibility, and process management. Within this section, you will find some of our solutions, divided by distinguishing features that are needed to cope with any processing need, in a very innovating and competitive way.
Indexed rotary tables
A technological evolution in the field of automatic metal buffing with rotary table systems. Our C.N.C units type buffing units represent a technological evolution – entirely designed on and developed by C.O.S.M.A.P. – in the world of the automatic rotary table for metal buffing.
Featuring up to 6 electronic axes (linear and rotary) combined with 2 axes on the rotary table, the C.N.C.s are capable of a high number of movements. This allows the buff to approach any workpiece, even ones with complex geometries.
Continuous rotation table
The most widespread –and most productive– product when it comes to buffing, constantly updated to keep up with the new demands of this field and with the new technologies.
Traditional buffing machine which gets its high productivity from the continuous rotation of the rotary table and its fixtures. Featuring many spindles, this machine is highly productive, especially when working with workpieces that possess regular and even geometric shapes. The buffing units to be positioned around the rotary table may vary in complexity and capability, according to the production needs: adding simpler or servo-controlled axes that will grant different degrees of movement. To allow a faster change of production, all the units are pre-set to be equipped with the auto-positioning function. To perform special buffing and mirror finishing processes, special manual-adjustable, working position-bound counter locks can be added. An additional, lightweight buffing units can be positioned at the center of the Rotary Table.
The mobile bench or static bench solutions can be coupled with any buffing unit, from the basic ones needed to operate on a linear surface to the most complex CNC ones. The necessity to find a way to perform the loading/unloading task within hidden times, meaning during the simultaneous processing of the same number of pieces, is very important for these units, too. The static bench has been designed so that the gripper remains steady and static while the piece moves to a different working station. The buffing unit may either be equipped with a simple axis that pneumatically checks the working pressure, therefore setting the adequate contact wheel position according to the position of the currently processed piece (thanks to controlled servo-axes). Or with up to nine axes that can be interpolated between the axes of the unit and those of the fixture. An automatic tool rack may be attached to multi-axis units, allowing the usage of a single unit capable of switching between up to ten tools, allowing going through an entire process without the need to shift between different units or increasing their number.
