Machining for single-part and series production parts
Frästechnik Krieger is a German supplier headquartered in Pettendorf/Adlersberg in the district of Regensburg (Bavaria). The sole proprietorship produces single-part and series production parts – from small to large series – for general and highly demanding mechanical engineering as well as for national and international customers. In-house, the company performs CNC milling with 3-, 4- and 5-axis simultaneous machining (up to 15,000 rpm, including rotary tables and vacuum clamping), CNC turning with C-/Y-axis and driven tools, Swiss-type turning as well as surface, cylindrical and vibratory grinding; this is supplemented by sawing, drilling and threading. Qualified subcontractors perform wire EDM, die sinking EDM, surface treatments (electroless nickel plating, anodizing, hard coating, burnishing), heat treatment and welding. Upon request, the company manufactures complete solutions such as fixtures, test stations and setting units. Materials processed include steels, aluminum alloys, stainless steels, castings, non-ferrous metals and plastics.
