Netzsch relies on automatic sawing centre

As a global specialist for pumping complex media, Netzsch Pumpen & Systeme GmbH, headquartered in Waldkraiburg, specialises in the development, production and sale of positive displacement pumps. For the manufacture of its pumps, semi-finished products in various grades with diameters of up to 540 mm are cut from whole bars and tubes. These saw cuts are then fed to subsequent turning/milling production processes.

The old sawing centre at Netzsch consisted of two stand-alone automatic bandsaws from Behringer and many individual cantilever-arm storage systems, which took up an entire production hall. The overhead crane was used to unload the raw material from the lorry, store the bars in the manual long-goods store and feed the saw. In addition, the materials were not catalogued.

“The manual labour required was enormous – our employees invested a lot of time searching for the required material on the shelf, transporting it to the saw and measuring it by hand,” says Markus Hanslmaier, project manager for production planning at Netzsch.

Today, Netzsch takes advantage of two Behringer automatic bandsaws. The HBE411A Dynamic and HBM540A are characterised by precise saw cuts and reliability in unmanned operation. This is ensured by the basic design of the two bandsaws in portal construction, the use of vibration-damping cast components, their saw feed system with servo motor and the reliable chip disposal system.

As a result, costs can be reduced during the sawing of semi-finished products by minimising processing allowances. Particularly with regard to the range of materials, which often includes expensive heat-treatable steels and duplex steels through to titanium and nickel-based alloys, there is a high savings potential. Moreover, the manual labour required by operators has been drastically reduced.
