124 MMS October 2017 TOOLING AND WORKHOLDING Schunk Magnos paralle l, square and radial pole plates are designed to ensure reliable work- piece clamping, quick workpiece changes and efficient grinding. A c c o r d i n g t o t h e c o m p a n y, t h e s q u a r e pole grinding plates with movable pole exten- sions can boost productivit y by as much as 200 percent compared to conventional parallel pole solutions; ensure uniform, deformation-free cla mping; a nd e na ble f lat wor k pie c e s to b e ground with micron precision regarding flatness and parallelism without multiple grinding opera- tions, changes to the clamping configuration, and time-consuming mounting. POLE PLATES ENABLE QUICK WORKPIECE CHANGES E D ITO R J E D D CO LE , jc o l e @ m m s o n l i n e.c o m for grinding large, thin workpieces with a material thickness of 4 mm or higher. With a grid size of 32 × 32 mm, the system can clamp small or narrow parts without deformation. The square pole plates can be clamped to already installed parallel pole plates for complementary clamping. The mono- block design is said to ensure stability and rigid- ity to minimize vibrations and improve surface finish. Additional stops can be installed in the threaded holes on the side, which is said to enable fast workpiece alignment. They are available in 12 standardized sizes, with individual dimensions also possible.
