BM permanent-magnetic clamping plate

Design: With transverse pole pitch and extremely low installation height. The high-energy neodymium-iron-boron NdFeB (noble earths) magnet system, the small installation height and the finest pole pitch offer a great variety of application options. The massive construction of the base body and the stable upper plate as well as the high-energy magnetic system ensure an extremely long and maintenance-free service life. All clamping plates are equipped with a removable actuating lever. Machining of the upper plate without impairing the holding force is possible up to a depth of 5 mm. Attachment on the machining tables is done using 2 clamping jaws. Holding force: max. 80–100 N/cm 2 (magnet quality N50) with ground workpiece clamping surface. Application: The clamping plates have been especially designed for clamping very thin and small workpieces. The clamping systems can also be used on spark erosion systems. Scope of delivery: Clamping plate with 2 stop bars. Note: Further dimensions available on request. The upper plate can be machined up to a depth of 5 mm without impairing the holding force. The clamping plates are normally supplied with 2 stop bars.

BM precision sine bar clamping table

Design: With the finest transverse pole pitch, easy to pivot across the longitudinal axis and permanent-magnetic clamping plates. The high-energy neodymium-iron-boron NdFeB (noble earths) magnet system and the finest pole pitch offer a great variety of application options. The massive construction and the stable upper plate as well as the high-energy magnetic system ensure an extremely long and maintenance-free service life. All clamping plates are equipped with a removable actuating lever. The sine bar clamping table is of all-steel construction, can be swivelled up to 75° and has an extremely low installation height. The gauge blocks can be adjusted up to 45°. The support surface for gauge blocks lies 2 mm below the 0 line, thus allowing very small angles to be set: the setting accuracy for the angle is ± 5 arc seconds. Machining of the upper plate without impairing the holding force is possible up to a depth of 5 mm. Attachment on the machining tables is done using clamping jaws. Lines of force: The magnetic field generated during operation is very low, and thus the residual magnetism in the workpiece and tool is insignificant. Holding force: max. 80–100 N/cm 2 (magnet quality N50) with ground workpiece clamping surface. Application: Ideal for the extremely precise grinding of very thin and small workpieces with non-parallel surfaces. The angles can bet set using gauge blocks. The table needs to be locked into place on the main shank in order to avoid any oscillations during the grinding process. The clamping systems can also be used on spark erosion systems. Scope of delivery: Sine bar clamping table with 2 stop bars and a sine lookup table. Note: Further dimensions available on request. The upper plate can be machined up to a depth of 5 mm without impairing the holding force. The clamping plates are normally supplied with 2 stop bars.
