Manufacture of precision machined parts and milling parts from all machinable materials. CNC turning (up to D 90 mm ​​rod) CNC turning (up to 250 mm in the feed) CNC long turning CNC multi-spindle turning (32 axes) CNC Machining Centers (5-Axis) Batch sizes up to 1000 pieces .... Piece including all subsequent operations up to the assembly In the field of machining there are many different ways of working. One is the CNC machining. Through this method, the milled parts get even complicated 3D contours. The CNC machining is done with machines with up to 8 axes. CNC turned parts can be made of different materials. For machining titanium, copper, brass, plastic, aluminum, stainless steel and other materials are suitable. Rotating parts in general can assume unusual shapes. In particular, the CNC milled parts often see pretty spectacular. Through its 3D contours CNC turned parts have a special effect.The machining is extremely versatile. Machining technology is used in various fields. Lathe parts, especially CNC lathe parts, are very expensive to manufacture. To produce a CNC lathe part, one special machines and more time than the normal CNC turned parts needed. The machining and especially the CNC machining requires a good education in the field. The partially very complex turned parts and just the CNC lathe parts require a tremendous expertise. A single CNC lathe part caused enormous amount of time. For these special turned parts, a particularly accurate work is absolutely necessary. For the purposes of machining are all chip forming materials. Depending on the material, the cutting is performed with different speeds. Are the turned parts made of wood, the cutting is done with high cutting speed and without cooling lubricants.Turned parts made of plastics, however, are processed at medium cutting speed. When machining water or alcohol are used for cooling. A special product from the metal cutting machines is the rotating part. Such automatic turned parts can be made ​​from almost all machinable materials. Just like the CNC long turning parts of the screw-cutting without technical knowledge can not be produced. All machined parts require special machinery for the production. Rotating parts are to be finished by hand hardly. Are the turned parts made of wood or plastic, the machining is possibly still done manually, but with harder materials the use of expensive machining is necessary. To establish automatic turned parts, can not be dispensed with the machines. Automatic turned parts are usually ordered in enormous quantities and from extremely strong materials. Also for CNC turned parts is similar. This machining is simply too specific. CNC turned parts requiring extreme precision. Turned parts of this type are mainly used in machine and plant engineering. These industries would not do without CNC turned parts, turned parts, and the entire range of machining technology. Milling Services, CNC turned parts, turned parts, and just such special products as a CNC lathe part are absolute precision products. As simple as the concept sounds cutting, this process but it is not. Cutting sounds like simple separation that hide behind it but also things like complex CNC turned parts or automatic turned parts, no one thinks at first. Without these highly intricate parts, especially without the screw-cutting work would be impossible in some areas.
