Rotogravure cylinders inner metal rolls are engineered and constructed of double-shell forged steel or chilled iron to maintain a uniform roll-face temperature, with a profile variance within 2°F (1°C) while operating at up to 500° F (260° C). Metal rolls are available with many options, which include: Nickel or chrome plated, Release coated, Precision ground, Heated or cooled, Hardened (case or through), etc.Â
To determination copper respectively chrome hardness of rotogravure cylinders simply, fast and accurately, UCI Hardness tests in Vickers range of light weight have the advantage that they are supposed to be non-destructive as the lasting surface indentation is microscopically small.
Measuring is effected by Vickers penetration procedure by ultrasonic evaluation of the indentation (UCI process). Different instrument adjustments (calibration values, penetration times, tolerance thresholds) for various metals can be stored in the device (e. g. copper, chrome, steel, zinc). A transfer to PC via Bluetooth or USB interface for long-term storing is possible on a very easy way.
The measuring values and the current average value are shown simultaneously and judged (cross means poor value) on the display in Vickers hardness HV or converted to others hardness scales. Furthermore, the whole measurement-series (statistic results, single measurement values) can be displayed at a glance.

Electric bicycles have many advantages. They do not have exhaust gas and noise pollution like cars and motorcycles. They are low speed and easy to drive. Generally, as long as you can ride a bicycle, you can master the operation of electric bicycles in less than an hour, so it is especially suitable for women and women. Elderly use. Of course, there is no denying that electric bicycles do not directly pollute the environment. However, if the waste batteries are not handled well, it will cause great pollution to the environment just like car batteries. However, with the development of the battery industry and finding better disposal methods for waste batteries, electric bicycles will continue to develop.
Smart electric bicycles generally consist of plastic parts, iron parts, electrical parts and brake systems.
The plastic parts mainly include the car body, various plastic decorative parts and rear fenders.
The iron parts mainly include frame, front fork, handlebar, rear hanger, saddle, bottom axle, rear shock absorber and other standard parts such as flywheel, chain, chain regulator and so on.
The electrical part mainly includes four major electrical parts (motor, controller, charger, battery) and various electrical auxiliary functional components (such as converters, flashers, lamps, horns, cables, and speed control brake handles).
