In order to control the 1~2-um protrusion height of mutilcore (MT) fiber endface in optic connectors, a micro grinding approach was developed using a 3D flock-structured film. The objective is to replace traditional lapping with loose-abrasive slurry. Experimental result shows that to achieve its height requirement and good quality, this approach requires 5-steps

Micro-mills look similar but operate in a different world than conventional cutters do… Makino says micro-milling involves features smaller than about 0.001″ (what they actually say is smaller than 0.00098″)

Hydrophilic carrier (micro crystalline cellulose) was applied in varying ratios (1:1, 1:2 and 1:4; drug to carrier ratio by weight) for enhancement of dissolution rate of Clarithromycin by co‒grinding technique. Co‒grinded Clarithromycin was prepared by compressing lubricated physical mixture (blend of Clarithromycin and micro crystalline

Micro-Sectioning of PCBs for Failure Analysis Bob Wettermann, BEST Inc Micro-sectioning (sometimes referred to as cross-sectioning)is a technique, used to characterize materials or to perform a failure mode analysis, for exposing an internal section of a PCB or package. Destructive in nature, cross-sectioning requires encapsulation of the

Jul 01, 2005 A Toshiba ULG-1002-axis ultraprecision grinding machine, with a positioning resolution of 10 nm in the X- and Z-axes was used.The grinding set-up shown in Fig. 4a and b provides a close-up view of the grinding set-up. On-machine truing and dressing of the micro wheel was done using the technique described in Section 2.2 before each grinding test

Aug 28, 2012 Mechanical micro-machining is further subdivided into cutting and abrasive machining, with the latter comprising precision grinding and polishing and the former being dominated by diamond turning and milling. Figure 1. Classification of

employed. They stated that the technique is more effective for electro-plated instead of vitrified cBN tools. Smith et al. [9] developed a robust diamond micro-grinding tool that produced superior ground surface and showed better tool life compared to conventional, electroplated dia-mond micro-grinding tools

micro-implants made using a powder injection molding (PIM) technique with those parameters in conventional titanium micro-implants. Methods: Sixty zirconia and 60 titanium micro-implants of similar design (diameter, 1.6 mm; length, 8.0 mm) were inserted perpendicularly in solid polyurethane foam with varying

May 18, 2019 Micro-grinding was applied for the fabrication of germanium immersion grating element which were to be used in spectrograph where high surface finish and minimum radius of the groove were required. Micro-grinding tool used was iron-cobalt hybrid metallic bond diamond wheels having particle sizes of 4000 and 20,000

Micro V-Groove Grinding Technique of Large Germanium Immersion Grating Element for Mid-Infrared Spectrograph. The 8.2m SUBARU large space telescope in Hawaii requires a mid-infrared high dispersion spectrograph with a resolution of 200000 at 10 m which employs a Germanium Immersion Grating (GIG) element. For this, the GIG element with a large number

Apr 25, 2019 In recent years, microtrenching has become an attractive way for urban developers to install fiber optic cable in heavily congested areas. It's less invasive than traditional installation methods—running cables up on powerlines or boring far deeper and wider trenches. And, if installed properly, the microtrench and its installed cables will stand the test of time

SteelBeads Micro are spherical cast steel grinding beads of tempered carbon steel. The fine-grained microstructure of the grinding beads give them a long lifetime and high breakage resistance. The SteelBeads Micro are available in a diameter range of 0.25 mm to 1.4 mm

The Modular Micro Reactions System, MMRS, comprises several components, through which the reagents flow in tiny channels. The small stainless steel components take on differing roles, including mixer, heat exchanger or sensor. The centerpiece of the structure is a special reactor, known as the Lonza reactor. This reactor accurately carries out
