About This Part
KGL machining optical rotating eyepieces. The barrel, gear set and other structural parts are commonly used in aluminum alloy because of their light weight and easy cutting. Stainless steel with high strength and corrosion resistance can also be used to support 360° rotation. Transmission gears require high wear resistance, and titanium alloy or hardened steel can be selected. Prisms and lenses are made of optical glass, and the light path is accurately transmitted. Or fused quartz is resistant to high temperature and low expansion. The anti-fouling coating uses a biological inert coating to inhibit biological adhesion. Our optical rotating eyepieces are made of high-quality materials and have very good product quality. You are welcome to place an order!
Precision machining
In the machining of the main body of the lens barrel, we use CNC lathes to turn the inner and outer circles in the turning process, and use three-axis and five-axis machining centers to mill the mounting grooves and threaded holes in the milling process. In the processing of the gear set, CNC hobbing machines are used to hob and mill the spur gears. Then the gear meshing surface is precisely ground and polished by a CNC grinder. The transmission mechanism uses a five-axis linkage machining center to mill the worm and worm gear structure to ensure rotation stability. Then we perform dimensional inspection, appearance inspection, and deburring. Finally, we perform surface treatment according to customer requirements.
Surface treatment technology
The aluminum alloy parts of the optical rotating eyepiece are hard anodized to improve wear resistance, and the stainless steel parts are passivated for corrosion protection; the gear surface can be plated with a lubricating film to reduce the friction coefficient. The prism fixing groove needs to be CNC turned, precision polished, and electrolytic polished. After this series of processing by the KGL machining factory, customer needs are met and the product quality of the optical rotating eyepiece is improved.
Core advantages of optical rotating eyepieces
Our optical rotating eyepieces can be flexibly observed at 360°, and the eyepiece can be rotated arbitrarily to adjust the viewing angle. The eyepiece angle can also be freely adjusted to improve the operating comfort. The viewing angle can be quickly switched during operation without disturbing sensitive samples, maintaining observation stability. During rotation, the optical axis is precisely aligned, the focal length is constant, and the observation is accurate. As a professional manufacturer of optical rotating eyepieces, we are willing to provide you with high-quality optical rotating eyepieces, and provide the best service and the best price.
