The Company
SK Schleiftechnik GmbH, which evolved from Durak Präzisionsschleiferei e.K. founded in 2009 in Erbach (Odenwald), is a specialized metalworking company with approximately 10 to 19 employees. The range of services includes cylindrical grinding (external, internal and non-circular grinding), surface grinding, turning with and without bar feeder, hard turning and CNC milling on a machine with tool changer (working envelope 500×400×400 mm). The offering is complemented by tool repair and the manufacture of stamps for deburring technology. Technical parts are manufactured for mechanical engineering, tool and die making, the automotive industry, hydraulic engineering and control technology; batch sizes for milling range from 10 to 1,000 pieces. Since 2009 the company has been certified to DIN EN ISO 9001 (TÜV Hessen/Profi Cert) and operates its own quality assurance with a height gauge and measuring microscope. Production sites are located in Erbach and Oberzent (Hesse); the Turkish market is served through the sales office MLK Makina in Gaziantep.
