About KIFFE Surface Grinding
KIFFE ENGINEERING GmbH is a contract service provider for the fine machining of flat surfaces, based in Villingen-Schwenningen. Founded in 1985, the family-owned company machins components from 1 mm to 1500 mm in size in tool steel, stainless steel, titanium, aluminium, carbide, engineering plastics, fibre composites, ceramics, glass and sintered materials. The processes include surface grinding, double-disk surface grinding, fine grinding, flat grinding, disk grinding, face lapping up to Ø 1600 mm, polishing up to Ra 0.02, flat honing, brush deburring, vibratory finishing, belt grinding and optical high-performance milling. In addition, cleaning (hydrocarbon, aqueous, modified alcohol), laser marking, nano-thin-film preservation, packaging and transport are offered – as complete machining from concept to finished component. With 24 high-performance fine grinding machines from Lapmaster Wolters (workpieces up to Ø 650 mm), over 250 million components have been machined in 25 years; customers come from mechanical engineering, automotive, medical technology and optics. Production is carried out according to DIN EN ISO 9001:2015 and ISO 14001 on 4,500 sqm of production space in two manufacturing buildings.
