In addition, the spindle speed of the SuperMach large-scale high-speed machining center produced by Cincinnati, USA is 60000r/min; the high-speed CNC boring and milling machine of Mikron Company, Switzerland, has a spindle speed of 42000r/min. 
Boiler Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.
It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase its enthalpy.
Bare tube type steam superheater coils, plate super heaters are commonly used.
