MB Maschinenbau says the ROBA Fentech moulding sander is ideal for batch one windows and mouldings. The laser-based part recognition at the machine inlet allows all sanding units to move into the required position, while a newly developed vacuum transport system holds short parts securely and four double brush units process the workpieces on all sides. Using the part return option, profiles can be processed by just one person. It is also possible to sand the parts again on the return movement at normal speed, or to choose the throughfeed option for high material output. A jump control of the sanding heads avoids over sanding of the short sides or miters, the company adds.
