Overview

About SPR GmbH

Who we are

SPR GmbH is a service provider for the production of turned and milled parts and your reliable contract manufacturer! The strengths of our production lie in the production of individual parts and small series. Regardless of whether it's turning, milling or turn-milling combinations, our machinery allows us to be very flexible for you. The maximum travel distances for milling are 1,100 x 600mm and with 5-axis simultaneous machining, we can process workpieces of up to 1.2 tons. On our lathes, we can produce chuck parts from the smallest diameters up to Ø800 mm. Shafts up to Ø500 mm and a length of 2000 mm can be produced. We have had our quality standards certified in accordance with ISO 9001:2015 with our QM system!
