Cost-optimised electro-mechanical joining module from KistlerKistler Instruments’ new NCFB electro-mechanical joining modules have been value engineered to provide a cost-effective option for many assembly and joining processes. Two versions of the new design are available, each with two measuring ranges. The smaller version has measuring ranges of 5 and 15kN with 200mm stroke at a speed of 250mm/s and the larger version has ranges of 25 and 50kN with a 400mm stroke length at 150mm/s. Both types retain the precision and flexibility of the NC modules with stroke length repeatability in real world conditions of 0.01mm.

The ram is driven by an electronically commutated AC servo motor controlled by servo electronics to ensure constant rotational and therefore translational speed. The integrated piezoelectric force sensor with integral charge amplifier and absolute displacement encoder provide accurate and reliable operation over the module’s long service life of approximately 5 million cycles. Standard functions such as block pressing, position pressing and force feedback controlled pressing as well as intermediate positioning are all supported.

These modules may be flange mounted vertically or horizontally and threaded bores of sufficient strength to hold tools are provided on the face of the ram. The maximum tool weight without holding brake is 10kg or 50kg with holding brake for the smaller unit and 15kg or 100kg for the larger.

In addition to economical initial cost, the new modules share the low installation and operating costs of the NC range, requiring only an electrical supply and cabling to the servo controller and monitoring and evaluation unit which communicates with the machine interface to provide OK/NOK commands. All Kistler NC joining modules are very energy efficient and low maintenance, compared with pneumatic and hydraulic systems, giving a very short cost recovery period – often less than 24 months depending on the specific application.
