Centreless cylindrical grinding
Optimal surface quality is particularly important for products made from POM-C, PA 6, PEEK, PTFE with diameters of at least 3.5 to a maximum of 100 mm.

Optimum surface quality is of enormous importance, especially for products made from fluoroplastics such as PTFE, PEEK, ETFE, PFA, PCTFE – depending on the later area of application. At BW Kunststoffe e.K., we can offer you tailor-made solutions with centreless cylindrical grinding for the smoothing grinding of plastic semi-finished products, specifically tubes and rods. In doing so, we use the centreless cylindrical grinding process to machine workpieces with diameters from at least 3.0 to a maximum of 100 millimetres and a max. length of 3000 mm.

Centreless grinding is one of the external cylindrical grinding processes, which are always used when an extremely smooth surface finish is required that cannot be achieved by milling or turning. The workpiece to be machined rests on a support rail between a regulating wheel and a grinding wheel, whereby the grinding wheel performs the plastic removal and separates the excess material in the form of chips. With this machining process, the workpiece is not fixed, so centring at the ends (centres) is not required. The regulating wheel of the cylindrical grinding machine drives the workpiece, while the faster-rotating grinding wheel performs the cutting. Centreless cylindrical grinding ensures that an optimum surface finish is produced with extremely high dimensional and shape accuracy. Semi-finished products, rods and tubes made of fluoroplastic thus have consistent diameters and can be further processed much better. This is also why grinding is an indispensable base technology in many manufacturing processes. In addition to extensive advice and customised development in the field of fluoroplastics, at BW Kunststoffe e.K. we have been offering centreless cylindrical grinding in the best quality for years, which is documented by certification in accordance with ISO9001/2015.
