PES plastic--PES polyethersulfone resin, is a transparent amber amorphous resin, with excellent heat resistance, excellent dimensional stability, and good chemical resistance. In addition, PES shows excellent reliability against sharp temperature changes, and has excellent reliability in long-term use at high temperatures. Excellent processability and excellent properties make PES have a wide range of applications.
PPSU is a slightly amber linear polymer. In addition to strong polar solvents, concentrated nitric acid and sulfuric acid, it is stable to general acids, alkalis, salts, alcohols, aliphatic hydrocarbons, etc. Partially soluble in ester ketones' aromatic hydrocarbons, soluble in halocarbons' DM. Good rigidity and toughness, temperature resistance, heat oxidation resistance, excellent creep resistance, corrosion resistance of inorganic acids, alkalis and salt solutions, ion radiation resistance, non-toxic, good insulation and self-extinguishing properties, easy to form and process.
The lightweight performance of PEEK materials and the comprehensive performance potential behind them are exciting. PEEK offers some representative products for the aviation industry, such as the PEEK polymer injection molded parts used to replace the expensive production of aluminum brackets.
When turning a slender shaft, due to the poor rigidity of the workpiece, several shapes of the turning tool have obvious influence on the vibration of the workpiece. The following points are mainly considered in the reasonable choice of geometric Angle of the CNC turning and milling compound machine tool:
the turn-milling compound can cover the processing of the five-axis machining center, but the five-axis can not do the turn-milling compound processing. Turning and milling compound is in fact the extension of lathe function, mainly to the lathe function and then add the power head, increase the milling and drilling function of the milling machine, thus reducing the product processing technology to improve the efficiency.
Turn-milling composite machining is a way of mechanical processing, turn-milling composite machining is not simply the two processing means of turning and milling into a machine tool, but the use of turn-milling synthetic motion to complete all kinds of surface processing, is a new cutting theory and cutting technology produced under the condition of the greater development of numerical control technology;
