Ivag launches RS15 precision tool grinding machine for grinding superhard material

The RS15 grinding machine developed by Ewag can economically produce and re-grind superhard material tools such as polycrystalline diamond and cubic boron nitride. The grinding machine is also suitable for grinding carbide and high speed steel tools. Compared with the traditional grinding machine, the RS15 has high production efficiency and high precision. The grinding and measuring of the tool can be done in one setup on the grinding machine. The grinder can be trimmed with a 3 to 5 axis grating.   The precision motion system of the machine tool can complete the tool arc constant back angle and variable back angle machining (maximum back angle 27°). Optional equipment for easy processing of PCD and CBN tools. The continuous grinding pressure allows for the effective grinding of superhard materials to ensure the quality and longevity of the tool edge. The automatic grinding wheel correction system ensures the end jump and the runout accuracy of the grinding wheel. The versatile accessories cover almost all requirements and can be used for grinding operations such as embossing, spherical, multi-face grinding deep hole drills.

Saliva Antigen Test

The COVID-19 Antigen Saliva Test kit is a lateral flow immunoassay intended for the preliminary screening and qualitative detection of nucleocapsid protein antigen from severe acuterespiratorysyndrome coronavirus SARS-CoV-2which causesthe Coronavirusdisease(COVID-19),in direct saliva sample from individuals suspected of coVD-19 by their healthcare provider within the first seven days of symptom onset.The COVID-19 Antigen Saliva Test kit is for professional use only and is intended to be used as an aid in the diagnosis of SARS CoV-2 infection.
SARS-CoV-2is anenvelopedsingle-stranded RNAvirus ofthe Baenus COVD-19 is an acute respiratory infectious disease. People are generally susceptible.Currently. the patients infected bytheSARS-CoV2are the main source ofinfection:asvmptomatic infected peope car also be an infectious source Based on thecurrentepidemiologica investigation, the incubation period is 1to 14 daysmostly 3to 7 days The main manifestations include feverfatigue and drycough.Nasa congestion, runny nosesore throatmyalgia and diarhea are found in a few cases.
Results are for the identification of SARS-CoV-2 nuceocapsid protein antigen. The SARS-CoV-2 antigen is generally detectable in upper respiratory specimens during the acute phase ofinfectionPositive results indicate the presence of SARS-CoV-2viralantigenshowever cinicai corelation with patient history and other diaanostic information is key to determine status of infection.Positive results don't preclude bacterialinfection or co-infection with other yiruses.eaatveresuts To patients with symptom onset for more than seven days should be treated as presumptive and confirmation with a molecular assayand patient management may be performed according to local regulations as needed.
