Flying knife processing double-head worm gear

As is known, since the worm wheel hob is a special tool, when a small number of worm gears are manufactured, it is often uneconomical to use a worm wheel hob, and the production cycle is also long, and in this case, a worm wheel cutter can be used for processing. When machining a worm gear with a flying knife, it is best to carry it on a hobbing machine with a tangential tool holder, and it is required to have a tooth movement and a forming motion during the machining process. In addition, only when the number of teeth of the worm wheel and the number of heads of the worm have no common factor, all the slots of the worm wheel can be cut out in one process with one cutter head. If there is a common factor, it cannot be processed once with a flying knife. In the middle, all the slots of the worm wheel are cut, and the slots on the worm wheel are machined at intervals, and then the other slots are processed by the teeth. The so-called tooth-toothing is to hang the teeth of the hobbing machine after the flying knife has processed a set of tooth slots.

Irregular Window

Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
When selecting windows, you should consider the following: material,transmission,scattering,wave front distortion,parallelism and resistance to certain environment.
China Star Optics offers all types of windows made from different materials.Special size and materials are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating on Optical Windows.
