Highly efficient 6-sided machining with loading and unloading system This line revolutionises the cutting and complete processing of large wooden posts/beams up to 7,000 mm in length. It is far-sighted to manufacture newel posts separately from other staircase components, especially so in industrial staircase production, where large quantities are required and cycle times are important. The PBZ 6S-7000 saves valuable production time on other machines and thus reduces costs. What, however, is so special about this well-thought-out concept, which features a loading and an unloading system and two gripper units? Based on a work list (nesting), wooden rods of 7,000 x 235 x 150 mm can be cut into the required sections and machined by the system, but also the processing of prefabricated newel posts with a machining allowance according to a work list or a bar code is feasible. The highlight: 6-sided processing is possible, since only one gripper and one clamping unit, each, hold the rods first in the infeed area and then after the transfer in the outfeed area. The system as a whole is ingenious: the bars placed on a cross conveyor in the loading area are buffered one behind the other. A gripper system singles the rods out before feeding. Then, their alignment and measuring in width, height and length takes place. Comparison of the results to the programme follows. A swiveling milling unit carries out all relevant milling and drilling operations, which permits the processing of newel post cross-sections from 235 x 150 mm to 60 x 60 mm. The star-shaped head in the unit, which is equipped with four tools, eliminates tool change times. The saw blade 550 mm in diameter cuts the rods to length. Then follows the transfer to the outfeed gripper. Once the final working steps at the bottom side of the newel post are complete, another cross conveyer pushes the finished posts from the outfeed area for manual removal.
