Well known for its multifunctional machining centers (rotary transfer machines), Precitrame Machines SA is also a historical provider of high performance polishing machines. The company has just presented a concept of robotic linear transfer machining centers with features that open new perspectives in terms of finishing and polishing. Meeting with Mr. Vincenzo Bonavoglia, Sales Director of the company.
The basic concept is simple, let’s imagine a working cell including a robot and two workstations allowing six or seven axes machining. Then let’s multiply these cells to create machines with two to five stations. Parts are gripped in holding devices that move from one station to the next. Thus, it is possible to implement a global chain of finishing (e.g. deburring, felting, polishing and brightening) within a single machine, and in one clamping.
Incomparable cycle time and flexibility The logic of the sequential work on several stations (and therefore always with operations in hidden time) allows the achievement of extremely short cycle times. Compared with a conventional solution, the tests show gains of 5 times or more.
To gain steps of production? Nowadays the quality produced by machining centers is steadily increasing and, depending on the part to be done, they can be directly loaded into the Cyberpolish T for all operations from grinding to brightening without having to pass through a specific grinding machine before. M. Bonavoglia says: "In some cases, specialised grinding operations before finishing are always necessary, but for all the others, we can directly finish the parts in one machine and in one clamping just after the milling operations".
Precitrame will be present at the next AMB with a multifunctional machining centre that will perform an automotive part. The new Cyberpolish series T will be shown through the many multimedia tools of the company.
