Tag Arkistot: Titaaniseoksesta valmistettujen osien jyrsintä

Numerical control processing integrates drilling, jyrsintä, kääntyminen, tylsä, kalvaus, tapping and other processes into a whole, which requires high technical quality of technicians. A true CNC master should have not only a wealth of theoretical level, but also superb practical experience and practical ability.

Automatic programming of CNC machining
The automatic programming of CNC machining is also called computer-aided programming, tuo on, most or all of the programming is done by the computer. Such as completing the calculation of coordinate values, compiling part processing procedures, automatically outputting and printing processing procedures and preparing control media.

One hundred years ago, high-speed steel cutting tools began to be used, and the cutting speed for milling ordinary steel was only 25-30m/min. Compared with carbon tool steel and alloy tool steel, the processing at that cutting speed is “high-speed milling”. Siksi, “high-speed steel” was named.

The high-speed milling system is a complex dynamic system, which is prone to chatter vibration when machining thin parts. Flutter is a very strong relative vibration between the tool and the workpiece during the milling process. This kind of vibration will destroy the relative correct position of the tool and the workpiece, and reduce the surface processing quality and milling efficiency. For a long time, cutting chatter has been a major research topic in the machinery manufacturing industry and milling processing.

Parts finishing is an algorithm based on curved surfaces. For multi-curved models, the lifting of the milling cutter should be reduced as much as possible. This requires that the generated milling tool path be within the same angular range or require different allowances in the axial and radial directions.

Ultra-precision cutting started with SPDT technology, which is supported by air bearing spindles, pneumatic slides, korkea jäykkyys, high-precision tools, feedback control, and environmental temperature control to obtain nano-level surface roughness. Diamond cutters are mostly used, which are widely used in the processing of copper flat and aspheric optical elements, plexiglass, plastic products (such as camera plastic lenses, contact lens lenses, jne.), ceramics and composite materials.
