The high-speed spindle system of CNC metal cutting machine; Wang Wensheng has high reversal speed; but there is no strict boundary. For the machining intermediate and CNC milling machine represented by high-speed cutting machine; generally refers to the maximum speed ≥ 10,000r/min The spindle system; and correspondingly has a high angular addition (decrease) speed; to complete the instantaneous speed of the spindle and start and stop. For the custom manufacturing industry, the machining accuracy is becoming higher and higher; the high-speed cutting spindle should also have higher The reversal accuracy of the spindle; the radial runout of the main shaft is less than 1 or 2 μm; the axial turbulence is less than 1 μm. In addition, the spindle must also have static and dynamic stiffness; to accept a certain cutting load and maintain high reversal accuracy. .

Hemispherical Aspherical Lens

Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. Aspheric lenses may also reduce the number of elements needed in a multi-element system. Aspheric lenses can reduce overall system weight while providing advantages such as increasing throughput or simplifying assembly.

Convex Aspheric elements are used to reduce aberrations, aspheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.

China Star Optics has strong and comprehensive technical capability, manufactured various aspherical products,including infrared material ZnSe,Ge,Si,ZnS etc.has already application in various high technology project and products.
